If a packet processing controller at a consumer node has failed to process a received packet within a predetermined amount of time, a packet processing control timer detects a time-out and informs a CPU of that. In response, the CPU issues packet processing suspend instruction and packet transmit instruction for the controller by way of a register. In accordance with these instructions, the controller suspends the current packet processing and produces header and data for a WRS packet, which is transmitted to a producer node through a bus. In this manner, a packet can be processed without causing a time-out at the producer node.

The present invention generally relates to a packet transmission/reception processor, and more particularly relates to a technique of exchanging packetized data using an IEEE 1394 digital interface.
Generally speaking, digital data is usually transmitted or received on a packet-by-packet basis. An IEEE 1394 interface is a typical one of various digital interfaces that exchange packetized data. As used herein, an "IEEE 1394 interface" means a next-generation high-speed serial interface, which is now being standardized by the Institute of Electrical and Electronic Engineers, Inc. (IEEE).
An IEEE 1394 interface can cope with two types of packet exchange, namely, isochronous and asynchronous packet exchange methods. The isochronous packet exchange is utilized to transfer data from an audiovisual appliance (e.g., digital video camera), from which real-time transmission is demanded strongly. On the other hand, the asynchronous packet exchange is utilized to transfer data from personal computer or external storage like hard disk drive. In that case, the data does not always have to be transferred in real time but must be highly accurate and reliable.
IEEE 1394-compliant asynchronous packets include a "request packet" representing an action to be performed and a "response packet" returning a result of an action performed responsive to a request packet. No matter whether a recipient has received request packet or response packet, the recipient always returns an acknowledge (ack) packet, which represents the reception state of the packet, to its sender. Unless the reception of an ack packet, returned in response to a request packet, completes processing, request and response packets are usually used in pairs. A packet exchange sequence using request and response packets is called a "transaction".
Hereinafter, it will be described with reference to FIG. 14 how an asynchronous transaction is carried out sequentially where Initiator sends out a request packet to Responder.
First, Initiator sends out a request packet to Responder B. On receiving the request packet, Responder returns an ack packet to Initiator. The ack packet returned may represent that the request packet should be sent again (ack—busy), that the request packet has been received safely but is now being processed (ack—pending) or that the action requested is complete (ack—complete). In the illustrated example, Responder returns an ack—busy packet to Initiator as shown in FIG. 14.
Responsive to the ack—busy packet, Initiator re-transmits the same request packet to Responder again. On receiving the request packet, Responder returns an ack-pending packet to Initiator this time.
As described above, the ack—pending packet represents that Responder has received the request packet safely but is now processing it. Accordingly, receiving this ack—pending packet, Initiator waits for Responder to return a response packet associated with the request packet.
The IEEE 1394 standard defines a time-out so that an action aborted, if any, can be detected during a transaction performed using request and response packets. Specifically, if an initiator receives no response packet even after a predetermined amount of time has passed since the initiator received an ack—pending packet responding to a request packet, then it is determined that the action requested was aborted due to some abnormality. Then, the initiator that sent the request packet can start the next transaction.
Stated otherwise, the responder that received the request packet should return an associated response packet within the predetermined amount of time. An initial value of the predetermined time is set to 100 ms, but is arbitrarily changeable at each end. On the other hand, if the responder has returned an ack—complete packet, then the initiator may start the next transaction immediately and does not have to return any response packet.
An "asynchronous connection" is known as one of the IEEE 1394 protocols utilizing the asynchronous packet exchange technique. The asynchronous connection is a transfer protocol defined for packet exchange between a "producer node" sending out a request packet and a "consumer node" returning a response packet. The asynchronous connection protocol is implementable by a system such as that shown in FIG. 15, for example. In the system shown in FIG. 15, a controller (e.g., set top box) issues a command for a consumer node (e.g., printer), thereby connecting the consumer node and a producer node (e.g., digital video camera) together. The connection protocol thereof is as follows.                (1) First, the controller performs a resource allocation on a plug control register (PCR) of the consumer node. In response, the consumer node returns an assigned plug address to the controller.        (2) Next, the controller supplies the plug address at the consumer node to the producer node, thereby initializing the producer node. In response, the producer node also returns its plug address to the controller.        (3) Then, the controller sends the plug address at the producer node to the consumer node to complete the connection.
When the connection is completed, the consumer node secures a memory region (which will be herein called a "segment buffer region") for storing the data transmitted from the producer node and issues a lock request (LRQ) packet to the producer node as shown in FIG. 16. In response, the producer node returns a lock response (LRS) packet to the consumer node as indicated by (a).
Then, the producer node sends data, which has been stored in a memory region with consecutive addresses as defined by the application on the transmitting end (which will also be called a "segment buffer region" herein), to the consumer node in the form of a block write request (BWRQ) packet. The IEEE 1394 standard defines the maximum size of a data field included in a packet that can be transmitted at a time. Accordingly, if the size of the data in the segment buffer region is greater than the maximum size, then the data is divided into multiple sections and then those divided sections are transmitted one by one. On receiving the BWRQ packet, the consumer node returns an ack—pending packet to the producer node. Next, the consumer node reads the address of the data included in the received packet and then stores the received data in the segment buffer region defined by the application on the receiving end. After the consumer node has entirely stored the data field of the received packet in the segment buffer region, the consumer node returns a write response (WRS) packet to the producer node as indicated by (b). On receiving the response packet, the producer node sends an ack—complete packet to the consumer node as indicated by (c). Transactions like this will be carried on until the data, stored in the segment buffer region defined by the application on the transmitting end, has been transmitted completely. These transactions are collectively called "data transfer processing".
When the producer node has transferred all the data from the application on the transmitting end to the application on the receiving end (i.e., at the consumer node), the producer node sends a lock request (LRQ) packet, representing that the transfer is complete, to the consumer node. In response, the consumer node returns a lock response (LRS) packet to the producer node as indicated by (d). In this case, the segment buffer regions as defined by the applications on the transmitting and receiving ends have the same top address and the same size. Also, the producer node sequentially sends the data stored in the segment buffer region and the consumer node also sequentially stores the data, included in the received packets, in the segment buffer region defined by the application on the receiving end.
Moreover, the asynchronous connection protocol requires that if the producer node fails to transmit the next request packet within 2 seconds after having received a response packet from the consumer node during data transfer, the producer node must send a request packet, indicating that state, to the consumer node as in (C) in FIG. 17. A processing step like this will be herein called "heartbeat processing".
Furthermore, unless the consumer node receives the next request packet or a packet indicating the heartbeat processing within 5 seconds after having sent the response packet, the consumer node must enter the time-out processing.
FIG. 18 illustrates a circuit performing such processing.
As shown in FIG. 18, one end of an IEEE 1394 serial bus 12a is connected to a physical layer controller 13, while the other end thereof is connected to another system (or node). A register 31 is coupled to a CPU by way of another bus 12g. The physical layer controller 13 performs various functions including initializing the bus 12a, arbitration and controlling a bias voltage. A link core circuit 14 receives a packet, transferred through the bus 12a, by way of the physical layer controller 13. Also, the link core circuit 14 generates or detects an error correction code for/from the packet received, adds a sign bit to the packet or detects the code (e.g., an ack packet code), for example. Moreover, the link core circuit 14 outputs a packet, which has been supplied from a transmission buffer 36, onto the bus 12a via the physical layer controller 13. Furthermore, the link core circuit 14 has a retry function. That is to say, even if the link core circuit 14 once failed to transfer a packet, the circuit 14 can try transferring the same packet again.
When the CPU writes header information on the register 31, data to be transmitted is sent to a packet transmitter 35. In response, the packet transmitter 35 makes a packet, which is then stored on the transmission buffer 36. In making the packet, the packet transmitter 35 provides the information about the packet to be transmitted for a reception controller 34. When the packet supplied from the packet transmitter 35 is written on the transmission buffer 36, the transmission buffer 36 passes the packet to the link core circuit 14. And then the link core circuit 14 transmits the packet by way of the physical layer controller 13.
On the other hand, the reception controller 34 receives a packet from the link core circuit 14 and analyzes the contents of the header field included in the packet. Also, to accurately identify the received packet (or to see if this is the packet that should be received in response to the packet transmitted), the reception controller 34 obtains information about the transmitted packet from the packet transmitter 35. Then, the reception controller 34 analyzes the information by comparing it to the header information of the received packet. Based on a result of the analysis, the reception controller 34 determines whether or not the packet should be accepted. And the reception controller 34 controls and instructs the link core circuit 14 not to accept the received packet if the packet is not paired with the transmitted packet.
The packet receiver 33 passes the received packet from the reception controller 34 to a packet reception buffer 32 so that the packet is stored on the buffer 32. And the CPU can read out the packet, stored on the packet reception buffer 32, by way of the register 31.
As described above, the IEEE 1394 defines a time-out to detect an action aborted during a transaction performed using request and response packets.
On the other hand, in the asynchronous connection protocol, if the data, included in the received packet, cannot be stored successfully in the segment buffer region at the consumer node within an amount of time defined by the IEEE 1394, then the consumer node cannot return a response packet in response to a request packet. Accordingly, a time-out is produced at the producer node.
However, the asynchronous connection protocol does not define how the processing should end at the producer node in case of time-out. Accordingly, a system complying with the protocol could not be established. Furthermore, since the producer node has already received an ack—pending packet, representing that the packet has been received safely, the time-out starts the next transaction while the current transaction is still incomplete. As a result, multiple transactions should be handled in parallel and multiple received packets should be processed at a time, thus making it much more complicated to establish a desired system.
Also, the asynchronous connection protocol demands that if the producer node cannot transmit the next request packet within 2 seconds after having received a response packet from the consumer node, the producer node must perform heartbeat processing to indicate the state. On the other hand, unless the consumer node receives the next request packet or the packet indicating the heartbeat processing within 5 seconds after having sent the response packet, the consumer node must enter the time-out processing. Thus, the asynchronous connection protocol requires a time management method different from the method applicable to data exchange using request and response packets in accordance with the IEEE 1394.
Furthermore, to transmit or receive a packet indicating the heartbeat processing at an arbitrary time, the producer node should perform time management in determining when the making and transmission of packets should be restarted, carried out or stopped. The consumer node should also perform time management to determine when the processing of received packets should be restarted, carried out or stopped.
Accordingly, the asynchronous connection protocol demands a packet transmission/reception processor that can transmit and receive packets while executing all of these functions.

What is disclosed herein is a novel metal coupling in combination with a fastening means to couple the metal coupling to a pipe surface, in that, the coupling is situated over a formed aperture in a pipe, a cable is looped over a supporting prong on the coupling, and a bolt, fastened to the cable, is tightened to draw the cable down onto the surface of a pipe, which in turn draws the metal coupling down onto the pipe in a secure manner.

This invention deals with a novel means for providing a branch point in a pipe or conduit. More specifically, this invention deals with a means of providing a leak-proof attachment to a pipe used for fluid transport.
Several devices have been disclosed in the prior art. Such devices are shown, for example, in U.S. Pat. No. 1,908,821, issued May 16, 1933 to E. S. Cornell Jr.; U.S. Pat. No. 2,221,934, issued Nov. 19, 1940 to R. G. Ferris; U.S. Pat. No. 2,421,596, issued Jun. 3, 1947 to A. W. Bruce et al.; U.S. Pat. No. 3,183,023, issued May 11, 1965 to B. E. Morrison; and U.S. Pat. No. 4,179,141, issued Dec. 18, 1979 to John W. Newman.
None of these devices disclose a device wherein the device can be attached to the pipe with the convenience of cable while providing the needed strengths for maintaining the coupling to the pipe in a leakproof fashion. The device of this invention allows the installer to be more efficient owing to the fact that just simple mechanical connections have to be made, in that the coupling is situated over a formed aperture in a pipe, a cable is looped over the supporting prong on the coupling, and a bolt tightened to draw the cable down onto the surface of a pipe, which in turn draws the metal coupling down onto the pipe in a secure manner.
It is believed by the inventor herein that such a device provides the efficiency of cabling but at the same time retains the required strengths to maintain the metal coupling on the surface of the pipe and prevent leaks therefrom.

Disclosed herein is a composition for use in the preparation of a Lacrosse sport ball, the composition comprising a prepolymer, the prepolymer comprising a multifunctional polyisocyanate and one or more polyols having a molecular weight of from about 1000 Daltons to about 5000 Daltons, and a curative comprising an amine or an additional polyol or a combination thereof. A Lacrosse ball formed from the composition exhibits a ball compression of from about 180 pounds to about 210 pounds or from about 90 pounds to about 210 pounds when tested in accordance with ND 049-12m12 Section 5.3 Ball Compression, and wherein the molded spherical ball exhibits a ball coefficient of restitution COR of from about 0.60 to about 0.70 or from about 0.50 to about 0.75 when tested in accordance with ND 049-12m12 Section 5.4 Ball Coefficient of Restitution COR.

According to a National Collegiate Athletic Association (NCAA) specification, a ball used in the sport of Lacrosse must contains at least 67 percent rubber. Generally, the remainder of the ball can contain fillers, additives and plasticizers. The materials of the ball can affect ball hardness which can prove troublesome owing to the high speed nature of the sport. During gameplay, the ball might collide with a player or spectator with the potential to cause serious injury. Personal protective gear does provide some protection but the lacrosse ball can frequently contact a player's body at high speeds and forces. The impact of the ball can cause bruises and broken bones. Attempts to ameliorate the damage from impact by a Lacrosse ball are described in U.S. Pat. No. 7,247,107 which describes a lacrosse ball that distributes its impact over a larger surface area by deforming to a much larger degree than conventional solid rubber lacrosse balls. One aspect of the invention describes a lacrosse ball having a hollow interior. This can be a disadvantage when trying to meet weight and volume specifications for a Lacrosse ball.
A second embodiment of the invention describes a lacrosse ball having a soft core and an exterior cover that is harder than the core. Another aspect of the invention describes a lacrosse ball having a dense core and a less dense outer layer over (e.g., over-molded) the dense core. In another aspect of the invention, the outer layer fully encases the dense core. The disadvantage of this invention is its complex structure of the Lacrosse ball and the associated increased manufacturing costs.

A system with a local data collector that collects power management data for a subsystem. The local data collector can determine whether a first formatting associated with a first channel between the local data collector and a system power management data collector is equivalent to a second formatting associated with a second channel between the local data collector and the system power management data collector, and in response to a determination that the first formatting and second formatting are not equivalent format the power management data according to the first formatting; store the power management data formatted according to the first formatting in a first location in a memory; format the power management data according to the second formatting; and store the power management data formatted according to the second formatting in a second location the memory.

Embodiments of the inventive subject matter generally relate to the field of power management, and, more particularly, to distributed collection of information for power management.
Power densities of systems have been increasing with the complexity of systems. The increase in power density affects thermal conditions and performance of the system. Power management of a complex system uses various sensors to monitor the myriad of components and subsystems and collect information about environmental conditions and events that impact system performance. Power management relies on timely communication of this information in order to take reactive or proactive actions to preserve performance.

The present disclosure provides a method, apparatus, and system to mount a filter bag to a wet/dry vacuum cleaner by providing an adapter for mounting the filter bag to a drain opening in the wet/dry vacuum cleaner drum and restricting the typical vacuum port, forcing the vacuum materials to enter through the drain opening and into the bag. The lid of the wet/dry vacuum cleaner can be removed independently of the bag to avoid rupturing the bag. Further, the bag can rest on the bottom of the drum for support.

The type of vacuum cleaners known as "wet/dry" vacuum cleaners can interchangeably suction either water or air. Thus, special structures accompany a wet/dry vacuum cleaner. Typically, a suction system with a motor creates the vacuum and is mounted in a lid that is removably attached to a collection drum. A portion of the lid, herein termed a mounting assembly, extends at least partially downward into the drum and mounts a filter support assembly and filter that generally covers a vacuum intake to the suction assembly in the lid. The collection drum receives the vacuumed materials in a loose unbagged state. The suction system in the lid suctions external air or water through a hose into an upper opening in the drum so that water or dirt is deposited throughout the drum below the opening. Remaining material, mainly air, then flows radially inward through the filter for filtering, continues through the filter support assembly into a suction impeller in the lid, and then is exhausted from the vacuum cleaner.
To empty the drum, the lid is removed and the drum is turned over to dump the contents into a waste container. Many larger wet/dry vacuum cleaners have a drain opening in the side of the drum at a low elevation. If the contents are primarily liquid, an operator can remove a drain opening cap from the drain opening to discharge the liquid contents into a waste container.
There is sometimes a desire for a paper filter bag for collecting fine, relatively dry debris. A number of non-wet/dry vacuum cleaners have a vacuum inlet transitioning into a tube that simply extends into a specially designed storage area where a paper filter bag can be placed and supported for such purposes. However, for a typical wet/dry vacuum cleaner, such capabilities are not enjoyed due to its multi-functional use. In the case of wet/dry vacuum cleaner where the vacuum inlet is integrated into the lid, it is impractical to install a paper filter bag on the inlet and then remove the lid and a full paper filter bag without rupturing the bag due to the suspended weight of the debris therein.
Therefore, there remains a need for a system, method, and device for mounting a filter bag to wet/dry vacuum cleaner.

Entering and evaluating group(s) of similar dependence hypotheses, such as time dependence hypotheses, and forecasting values of a variable based on the group(s) of similar dependence hypotheses. The group(s) of similar dependence hypotheses may be used to forecast requests for an Internet resource or Internet resources having one or more particular attributes. The entered group(s) of similar dependence hypotheses may be evaluated based on known data, such as past requests for Internet resources or Internet resources of a particular type.

.sctn.1.1 Field of the Invention
The present invention concerns time dependency of certain variables such as, for example, the time dependency of the use of (e.g., requests for) Internet resources. In particular, the present invention concerns entering and evaluating time dependency hypotheses and forecasting variable values based on the time dependency hypotheses.
.sctn.1.2 Related Art
People rely on forecasting, of one type or the other, in many ways. For example, people may rely on weather forecasts to determine what to wear or what crops to plant, people may rely on forecasts of a stock market index or of a particular company's earnings when investing money, and companies may rely on demand forecasts when deciding what and how many products to produce. Forecasting or predictions also extend to less essential issues, such as what team will win this week's football game or what movie will win this year's Academy Award.
Some forecasts are made by detecting temporal patterns in known data and extrapolating the data forward based on the detected patterns. For example, a forecast of the number of people making a telephone call during a particular time period in a day may be made based on detected temporal patterns in historical data of the number of people making telephone calls during that particular time period in past days.
One general purpose of forecasting is to predict what people will want in the future so that those wants can be met. For example, in the context of networked computers, such as the Internet, resource servers (also referred to as "web sites" or "Internet sites") service requests for content (e.g., documents, HTML ("Hyper Text Mark-up Language") pages, JPEG ("Joint Photographic Experts Group" encoded) images, MPEG ("Motion Picture Experts Group" encoded) video, audio information, etc.) from clients. If client requests can be accurately forecast, resource servers may be adapted to service such client requests in a more efficient (e.g., in terms of ease of navigation, download time, availability, etc.) manner.
Forecasts of requests for Internet resources may be made based on the resource itself, or one or more attributes of the resources. Different Internet resources may have different attributes. For example, an Internet resource providing a stock market report may have "FINANCIAL" and "HTML" attributes, an Internet resource providing an image of a famous painting may have "ART" and "JPEG" attributes, and a video clip of baseball highlights may have "SPORTS" and "MPEG" attributes.
FIG. 1a is a notional plot 110 of requests for an Internet resource which provides an interactive game, over time. As shown in FIG. 1a, requests may increase after working hours and increase dramatically (See 115a and 115b) during the weekends. FIG. 1b is a notional plot 120 of requests for an Internet resource which provides a download for a computer program, over time. If the download is provided for free during a certain time period, a spike 125 in requests may occur during that time period. FIG. 1c is a notional plot 130 of requests for an Internet resource having content which is updated every Wednesday. As shown in FIG. 1c, requests may increase on Wednesdays (See 135a and 135b) and taper off for the rest of the week.
As can be seen from the above examples, the temporal properties of Internet resource requests may depend on the attributes of those resources. If the number of attributes is relatively small, such patterns might be readily discernable merely by looking at temporal patterns in the plots of data (e.g., requests). However, large Internet sites may have resources with thousands of attributes. Thus, a tool is needed to automatically forecast requests for Internet resources.
One of the most popular time series models used in forecasting is the seasonal ARIMA (or Auto-Regressive Integrated Moving Average) model. Unfortunately, however, a fundamental assumption of the ARIMA model makes it unsuitable for forecasting events which exhibit non-homogeneous time intervals (e.g., different patterns on weekdays and weekends). It is believed that requests for Internet resources are not time-homogeneous. Thus, a tool for forecasting events that are not time-homogeneous is needed.

Methods and apparatus for entering and evaluating time dependence hypotheses and for forecasting based on the time dependence hypotheses entered


An information recording system for recording information on an optical disc using a reference clock signal generated based on a push-pull signal including a wobble frequency component, the system includes an amplitude obtaining unit for obtaining an amplitude value of the push-pull signal, a threshold calculation unit for calculating a displacement threshold of the push-pull signal based on the amplitude value obtained by the amplitude obtaining unit, and a noise reduction unit for generating a corrected push-pull signal by correcting the push-pull signal such that a displacement exceeding the displacement threshold is reduced. The reference clock signal is generated based on the corrected push-pull signal generated by the noise reduction unit.

1. Field of the Invention
The present invention relates to an information recording system and information recording method for recording information on an optical disc, and particularly to the technique of precisely generating a reference clock signal for use in, for example, precisely determining a recording position when recording information on a wobbled optical disc such as a DVD-R.
2. Description of the Prior Art
When recording data on a DVD-R, information recording systems detect a push-pull signal including a wobble frequency component of an information track by applying a light beam to the information track. Part of the light beam happens to be applied to pre-pits on tracks adjacent to the information track, which causes signals corresponding to the pre-pits to be incorporated with the push-pull signal detected from the information track, resulting in a problem of not being able to detect a quality push-pull signal.
The signals corresponding to the pre-pits have impulse characteristics, i.e. characteristics to have a signal uniformly distributed over the entire frequency band, and thus, they cause another problem of not being able to remove the signals corresponding to the pre-pits only by a simple filter.
Japanese Laid-Open Patent Publication No. 10-241260 discloses an information recording system free from such problems.
The information recording system disclosed in the publication includes a wobble signal extracting unit 22. The wobble signal extracting unit 22 includes, as shown in FIG. 1 in the publication, a limit-level generator 25, a limiter 26, a BPF 27, and a binarizer 28.
The limit-level generator 25 generates upper limit signal SUL and lower limit signal SWL, which may be modulated according to pre-information signal SPP and limit the level of SPP, based on pre-information signal SPP, i.e. a push-pull signal, outputted by a pickup. The width between upper limit signal SUL and lower limit signal SWL is set to a predetermined level width.
The limiter 26 uses the limit signals generated by the limit-level generator 25 to suppress a noise signal derived from pre-pits in pre-information signal SPP and outputs limited pre-information signal SPL.
The BPF 27 removes a high frequency component from the limited pre-information signal SPL to output wobble signal SB.
The binarizer 28 binarizes wobble signal SB to output extracted signal SDTT.

Information recording system and an information recording method


The disclosure discloses a scheduling resource configuration method and apparatus, user equipment, and a base station, so as to obtain, from a location such as a core network or a user terminal, related data, of a service that is currently executed by the user terminal, and further generate and configure scheduling configuration information such as SPS scheduling configuration information based on the data. The base station and the user terminal both run, based on the generated scheduling configuration information, the service that is currently executed by the user equipment. This disclose dynamic configuration of a scheduling resource such as an SPS resource, effectively saves resources, such as PDCCH resources, used for a scheduling indication in a system, and can also ensure, to fullest extent, data transmission quality of some services whose data packet sizes, periods, or the like change.

Semi-persistent scheduling (SPS) is also referred to as semi-static scheduling. Current dynamic scheduling means: Each time user equipment (UE) is to receive or send data, a base station is required to send a scheduling resource. In SPS, semi-static configuration of a radio resource is allowed, and the resource is periodically allocated to specific UE. Correspondingly, the UE periodically transmits service data based on the configured radio resource.
A Long Term Evolution (LTE) system is used as an example. An eNodeB (eNB, base station) specifies, in a transmission time interval (TTI) by using a physical downlink control channel (PDCCH) scrambled by an SPS cell radio network temporary identifier (C-RNTI), a radio resource used by UE. After each period, the UE receives or sends data by using the resource. The eNB does not need to deliver a PDCCH in the subframe (referred to as an SPS subframe) to specify the allocated resource. Because SPS has a characteristic of "an allocated resource can be used for a plurality of times", PDCCH resources used for a scheduling indication in the system can be effectively saved.
However, in all existing configuration manners, SPS configuration is directly performed on a network side for UE. When there is a relatively large change in a data packet of a service, of the UE, executed by using a configured SPS resource, for example, there is a relatively large change in a data packet size or a data packet interval, data transmission of the service cannot be well implemented by using the configured SPS resource. In addition, an SPS resource configured in an existing configuration manner cannot satisfy an SPS requirement of a service whose data packet size or packet interval changes.

Disclosed is a coating for gas turbine components including at least one material having vibration-damping properties. Further disclosed is an airfoil of a gas turbine having damped vibrational characteristics including an airfoil substrate and a coating applied to the airfoil substrate including at least one material having vibration-damping properties. A method of damping vibration of a gas turbine component includes applying a coating including at least one material having damping properties to the turbine component.

The subject invention relates to turbines. More particularly, the subject invention relates to damping of turbine components.
Operation of a turbine subjects many of the turbine components to vibrational stresses. This includes components of the compressor, hot gas path (HGP), and combustor sections of the gas turbine. Vibrational stresses shorten the fatigue life of components subjecting them to potential failure, especially when the components are also subjected to the harsh environment of a gas turbine.
One way to reduce vibrational stresses and extend the life of components is to provide a means for damping the vibration of the component thus altering vibrational characteristics in such a way to increase structural integrity of the component and extend its useful life. Previously, mechanical means have been used to damp vibration of turbine components. Examples of the mechanical means include a spring-like damper inserted in a rotor structure beneath the airfoil platform, or a damper included at the airfoil tip shroud.

A holder for skis includes two clamping jaws which are arranged symmetrically opposite each other relative to a vertical plane. The clamping jaws are mounted so as to be rotatable in dependence on each other about horizontal axes which are arranged parallel to each other and spaced from each other. The axes are defined by bolts which are fastened to a support plate. The clamping jaws have bearing sleeves which surround the bolts. The bearing sleeves have at their ends facing the support plate freely cantilevering arms which are directed toward each other and which are in rotational engagement with one another. The effective surfaces of the clamping jaws which face toward each other are convex arc-shaped, wherein the distance of the imaginary generatrix which forms the arc and which extends parallel to the respective axis from the axis of rotation of the clamping jaw steadily increases from the lowermost arc portion to the uppermost arc portion.

1. Field of the Invention
The present invention relates to a holder for suspending skis. The holder includes two clamping jaws which are arranged symmetrically opposite each other relative to a vertical plane. The clamping jaws are mounted so as to be rotatable in dependence on each other about horizontal axes which are arranged parallel to each other and spaced from each other. The axes are bolts which are fastened to a support plate.
2. Description of the Related Art
A number of possibilities have become known for securely suspending skis outdoors, on a wall or on a frame.
Austrian Patent No. 258 771 discloses a holder for suspending pairs of skis in which the holder has a three-sided E-shaped or S-shaped holding stirrup which is pivotally mounted on a horizontal arm. An outer stirrup side is mounted in a bearing sleeve so as to be rotatable about its longitudinal axis. The other outer stirrup side and the middle stirrup side serve to receive the skis. The weight of the skis cause these two stirrup sides to be pressed against two oppositely located surfaces of the pair of skis, wherein the weight of the pair of skis further increases the holding force. In holders of this type, it can always happen that the skis are released and fall down when the skis are unintentionally touched, particularly when the rubber sleeves placed on the stirrup sides are damaged.
In addition, a holder for skis is to be mentioned which includes a support plate with two rotatable rollers arranged next to each other. The axis of rotation of each roller is eccentric to the center axis of the roller. A circular arc-shaped recess is cut into each roller. Compression springs are placed in each recess. The compression springs have the purpose to rotate the two rollers relative to each other. The rollers are covered with rubber linings. The skis are clamped between the two rollers. This device is of very complicated construction. Moreover, the device is also not very practical. The rollers are pressed on as a result of the force applied by the above-described springs. If the skis are to be placed in the holder, the two rollers must be rotated to such an extent that a sufficiently wide gap is created between the rollers, so that the skis can be placed between the rollers. Since each of the two rollers is supported and spring-loaded individually, it is necessarily required for rotating the rollers to use both hands and, therefore, another person is necessary for placing the skis in the open gap between the rollers. This is a very cumbersome manipulation.
A simple holder for handles is known from Swiss patent 365 501. In this holder, two L-shaped jaws are freely and individually pivotable about parallel axes mounted on a support plate. This type of holder is probably sufficient for simple implements with handles, such as brooms or brushes. However, this device is not useful for skis which have a substantial weight. This is because each of the jaws can assume an arbitrary position since the two jaws are freely pivotably mounted. Thus, the handle can be easily moved either to the right or to the left, so that the angle of the jaws relative to the skis are changed, wherein one of the angles is increased and the other is decreased. This results in an instable support which is not useful for heavy objects, such as skis.
U.S. Pat. No. 1,609,666 also shows and describes a simple holder for handles. However, in this case, the two jaws are connected to each other through a common tension spring. In this holder, a symmetrical position of the jaws relative to each other can only be achieved when the two jaws are jointly pivoted upwardly to such an extent that the handle can be inserted and the two jaws can then be returned uniformly until they make contact with the handle. This is because if only one jaw were actuated, the second jaw would assume an angular position which would correspond to the position of the straight line connecting the center of gravity and the point of application of the spring on the other lever. In other words, the two jaws would have a very different angular position relative to the horizontal. The two jaws would only assume the same angle if the two jaws were completely without load. In that case, the jaws are located on the horizontal straight connecting line between the two pivot axes.


A reinforcing structure for a member such as a truck bed comprises an elongate, trough-like body having side walls diverging from a base and terminating at their free ends in outwardly turned mounting flanges. Fixed to the base and extending therefrom between the body side walls is an elongate strut the height of which corresponds to that of the side walls. Spanning the distance between the strut and each side wall is a plurality of spaced apart ribs, the upper edges of which are flush with the strut and flanges. The side walls of the body may have a thickness less than that of the strut which, in turn, may have a thickness less than that of the ribs.

Vehicles of the kind having a tiltable dump body often require reinforcing of the vehicle bed so as to rigidify the bed against deflection and torsion to which the bed may be subjected during its tilting movements. Trough-like reinforcing structures heretofore have been welded to the lower surface of the vehicle bed, but such structures have less than desirable reinforcing characteristics unless they are constructed from relatively heavy gauge sheet material which is more expensive than lighter gauge material and more difficult to handle due to the greater weight of the material. In some instances the length of the vehicle bed is so great that a fairly large number of such reinforcing troughs must be utilized if any significant reinforcing of the bed is to be achieved, as a consequence of which the weight of the vehicle is increased materially with a consequent reduction in its load carrying capacity and a reduction in its fuel efficiency.


A sensor for use in read/writing the magnetic pattern stored in a magnetic storage disk uses a Corbino structure comprising inner and outer electrodes enclosing a magnetoresistive element. The sensor is formed at the front surface of a stack of superposed layers of which the first and fifth are of a high resistivity semiconductive material, the second and fourth are of a magnetoresistive material and the third of a metal or composite structure. The second and fourth layers form a loop around the third layer, the first and fifth form a loop around the second and fourth layers. A dopant is diffused into the front surface of the stack to convert edge portions of the first and fifth layers to low resistivity to form a conductive loop that serves as the outer electrode of the Corbino disk, the third electrode serving as the inner electrode.

As is known, a Corbino structure comprises a magnetoresistive element, an inner electrode surrounded by the magnetoresistive element and an outer electrode surrounding the magnetoresistive element. When a voltage is applied across the inner and outer electrodes to establish a radial electric field in the magnetoresistive element and the element is used to read a pattern stored on a magnetic storage medium, the current flowing between the electrodes will be modulated by magnetic flux passing perpendicularly through the radial electric field. Such modulation can be detected and amplified to provide a replica of the signal information stored on the magnetic storage medium. Because of the small dimensions involved in such a sensor, it is difficult to make it reliably and simply.
The main object of the present invention is a process for making such a device reliably and simply, but it will be appreciated that the principles involved in the processing may have wider application to the processing of other semiconductive devices.

Transmission between electric motor and tool shaft, for instance for hand tools such as an electric screwdriver and the like, which transmission is provided with an adjustable breaking coupling for discontinuing the drive torque on the tool shaft when a predetermined resistance moment on this tool shaft is exceeded, wherein the breaking coupling in the form of two mutually slidable parts is provided with a signal generator for controlling a member influencing the motor feed, which signal generator comes into operation as soon as the two parts slide relative to one another when the set torque is exceeded, so that a disengagement takes place between motor and tool shaft immediately after the desired resistance moment is exceeded, wherein the inertia of the rotating parts no longer has any effect on the tool shaft so that it stops immediately.

The invention relates to a transmission between an electric motor and a tool shaft, for instance for hand tools such as an electric screwdriver and the like, which transmission is provided with an adjustable breaking coupling for discontinuing the drive torque on the tool shaft when a predetermined resistance moment on this tool shaft is exceeded.
In electric tools, particularly electric hand tools, it is known to place a slip or claw coupling between the electric motor and the tool shaft, whereby in the case of overload the tool shaft is no longer subjected to the full torque of the electric motor. The drawback to such a system is that when the motor is driven, a torque is still exerted continuously or intermittently on the tool shaft. This can be disadvantageous in particular applications. In addition, such couplings are noisy and greatly subject to wear.
There also exist protection circuits which cause the motor feed to be switched off and/or braked as soon as overload of the motor occurs. Such a switch-off system is difficult to embody particularly in conjunction with battery-powered DC-motors because the high amperages could present adverse consequences during switch-off upon overload. Moreover, the mass inertia of the rotating parts continues to act on the tool shaft during switch-off.
The object of the invention is to provide a transmission wherein a disengagement takes place between motor and tool shaft immediately after the desired resistance moment is exceeded, wherein the inertia of the rotating parts no longer has any effect on the tool shaft so that it stops immediately.

Torque release mechanism for an electronically powered tool


The purpose of the present invention is to provide a laser light source module that is capable of heat dissipation from a laser device and of suppressing the diffusion of a light beam due to the close arrangement of the laser device. The laser light source module comprises a stem that is a base plate and first and second laser assemblies disposed on the stem. Each of the laser assemblies comprises a multi-emitter LD bar that is a laser device emitting a laser light along an optical axis, and a holding member having a mounting surface parallel to the axis, the multi-emitter LD bar being mounted on the mounting surface. The first and second laser assemblies are positioned such that the optical axes of the assemblies are parallel to each other and that the mounting surfaces of the assemblies are arranged opposite to each other in parallel.

Optical apparatuses such as digital cinemas and projectors are required to have a lower cost and a power-saving property. Such an optical apparatus has a plurality of laser devices disposed therein as light source modules so as to achieve a necessary optical output. Use of optical coupling members such as optical fibers coupling light from modules in the optical apparatus is one of the factors determining the cost. Therefore, by increasing the optical output of a single module and reducing the number of laser devices in the optical device, the cost required for the optical coupling members can be reduced, and consequently, the cost per oscillation output of the optical apparatus can be lowered. This leads to a demand for a high-output type light source module having a high oscillation output as a single module.
Conventionally, for example, Patent Documents 1, 2 disclose a structure having a plurality of LD elements arranged in a uniaxial direction on the same plane and coupled to a fiber through two kinds of lenses so as to achieve a high optical output. However, since light-emitting points spread in the uniaxial direction (direction parallel to an emitter array), a divergence angle (etendue) of a synthesized optical beam becomes larger in the direction and, when a predetermined number of LD elements is exceeded, an optical coupling loss increases at the time of fiber coupling, causing a problem of reduced light emission efficiency.
Patent Documents 3, 4 disclose a package structure having a plurality of LD elements mounted on side surfaces of a common holding member in a module and thereby improving an optical output. However, since the structure of Patent Documents 3, 4 has the plurality of LD chips held by the one holding member, a distance between LD chips cannot be shortened, and a divergence angle (etendue) of an optical beam becomes larger in the uniaxial direction (the direction between the LD chips), an optical coupling loss increases at the time of fiber coupling, still causing a problem of reduced light emission efficiency.
Patent Document 5 discloses a package structure in which a plurality of LD chips is mounted in a module by using a stepped holding member. However, the stepped holding member makes it difficult to miniaturize a package as a whole.


Presented is a system that allows a user who subscribes to the system to avoid viewing commercials with unacceptable content (e.g. alcohol related, sexual content) during real-time television broadcasts. The system has a residential component consisting of a control unit having a user interface a local database and a specialized router, a remote processing component having monitoring stations where the monitored network feeds are processed, and a system DBMS component that stores channel and user information in real time. The control unit is connected to the internet, such as via a wireless connection on the user's network, to retrieve remotely-stored data obtained through monitored network feeds. The control unit retrieves real-time data associated with viewable content and applies logic to switch the viewing channel or signal source for display on the television. The monitored network feeds are viewed on the system's monitoring stations and the earliest feed for each monitored channel determines the channel content.

As known in the prior art, television content is provided to home and businesses by local broadcast providers and network content providers. Local broadcast providers can deliver programming over the air (OTA) or through a local subscriber service, such as cable or satellite broadcasters. Many television networks, however, only provide programming content through local subscriber services.
National and regional network providers distribute their programming and commercial content through network feeds to the local broadcast providers and local subscriber services. The network feeds therefore provide the earliest available source for the content. Local broadcast providers and local subscriber services may replace network commercial content with local commercial content and otherwise process the content, such as compressing digital data. As a consequence, there are lags between when content is available on the network feed and when the content is delivered to the user.
To view programming from a local subscriber service, a subscriber device (e.g. cable or satellite decoder box) must be installed at the user location and connected to a television input. The user typically selects a viewing channel using a remote control unit that communicates with the subscription device using an infrared signal protocol.
Often a user may have an interest in watching multiple programs that are broadcast at the same time. The user can time-shift by recording one program while watching another program. That solution may not meet the user's needs. Instead, while viewing one program, the user may wish to change channels and view another program. That is typically done by manually selecting another channel. The user will then view the other program until deciding to change channels again. Such channel surfing is fairly common among sports fans, who may be interested in multiple live games during any one time slot. To facilitate channel surfing, some televisions employ Picture-In-Picture (PIP) technology to tune to multiple channels and display the content from each channel on the television monitor.
Regardless of the reason, there are some predictable times during programming when a user may wish to change the channel. One instance is during a commercial break, during which the user may prefer to watch programming on another channel instead of the commercials on the current channel. Another instance is during broadcast of a commercial with content deemed unsuitable to the user.

System to avoid viewing commercials in real time


Brassiere tapes having a body portion and a pair of overlapping tabs extending outwardly therefrom are manufactured by providing a continuous strip of material for the tapes having fastener elements spaced along the strip and layers in the body portion and in each of the tabs weldable with ultrasonic vibratory energy. The tabs are separated physically from each other such that the individual layers in the strip may be simultaneously severed and welded across the body portion and the tabs when interposed between ultrasonically vibrating horn and anvil devices, except that the tabs which are physically separated from each other are not welded to each other. Compliant means for mounting of the anvil is provided so that the cutting edge for severing the tapes from the strip which is associated with the anvil is not readily dulled by the repetitive contacting engagement of the horn and anvil surfaces in the operative position. Advancing the strip between the horn and the anvil is accomplished by means of the elements on the strip for continuously producing tapes having a desired number of elements thereon.

1. Field of the Invention
The present invention relates generally to the manufacture of articles from an elongated continuous strip, and more particularly concerns an improved apparatus and method for producing tapes to be sewn to brassieres in the manufacture thereof.
In the manufacture of brassiere wearing apparel, or undergarment, one tape having hooks thereon and another tape having eyes theron are attached to opposite sides of the brassiere for adjustable coupling in a manner well known.
While the instant invention will be primarily described in conjunction with the manufacture of brassiere tapes, it will be apparent that the same principles disclosed herein may be applied to other articles formed from a continuous strip having overlapping layers of fabric, or material, with a pair of tabs or other protrusions extending therefrom for subsequently securing the article to a garment or other end product.
2. Description of the Known Art
In the known art, the useful life of an anvil or horn with ultrasonic energy utilized to simultaneously weld and sever a strip into the tapes on a sequentially repetitive basis is limited. To accomplish this simultaneous welding and cutting, either the anvil or horn is provided with a surface formed as a knife edge that extends transversely to the path of travel of the strip.
For example, the anvil may be provided with a cutting or knife edge and the horn with a mating surface. The vibratory mechanical motion hammering the cutting edge on the horn at the end of each welding and cutting cycle then tends to dull the cutting edge over a period of time.
The prior art, as for example illustrated in U.S. Pat. No. 4,025,374, issued May 24, 1977, shows that ultrasonic energy may be utilized for simultaneously wleding and cutting overlapping layers of weldable material. But it does not show how to prolong the usefulness of ultrasonic apparatus to reduce "down time" which is most expensive in production facilities.

Ultrasonic apparatus for manufacturing brassiere tapes


A method of attracting Periplaneta americana L comprising positioning a composition comprising an attractant-ingestion stimulant in a location wherein it is desired to attract Periplaneta americana L, said stimulant comprising an amount of at least one compound selected from the group consisting of ar-.alpha.-tetralol, ar-.beta.-tetralol, ac-.alpha.-tetralol, .alpha.-naphthol, .beta.-naphthol and iristectorumin's alcohol effective to attract Periplaneta americana L.

1. Field of the Invention
The present invention relates to attractant-ingestion stimulant preparations for Periplaneta americana L.
Periplaneta americana L is a species of the cockroach which is most known and distributed throughout the world. In Japan, it is the largest species of the house cockroach which is most damage-producing. Among known methods of extermination of the cockroach are ones employing a tackiness plate or toxic bait in which an attractant-ingestion stimulant agent of the invention can be incorporated to enhance the exterminative effects.
2. Description of the Prior Art
As substances which possess attractant effects for the cockroach, there are known sex pheromones produced by extraction from the feces and the mid-gut of Periplaneta americana L, several monoterpenoid compounds (see Japanese Patent Laid Open Nos. 29502/1981, 30905/1981, 30940/1981, 79602/1981, 79640/1981, 87536/1981 and others), fatty acids such as myristic acid and palmitic acid, esters thereof and others (see Japanese Patent Publication No. 320/1969).
Extraction of the sex pheromones, however, requires a large number of the insect, Periplaneta americana L, and synthesis of the monoterpenoid compounds involves a complicated process. Moreover, the sex pheromones are excitable substances, and the cockroach is hardly immobilized. Also, activities of the sex pheromones are markedly reduced when male and females insects are coexisting [S. TAKAHASHI, C, KITAMURA: Appl. Ent. Zool. 2(3), 133-141 (1972)].
Fatty acids such as myristic acid and palmitic acid and esters thereof not only possess a low attractant activity but also produce no immobilizing or ingestion stimulant effect alone and need addition of starch or sugar.
Accordingly, there have necessarily been increases not only in production cost but also in size of the attractants, with inconvenience in use associated.

Attractant-ingestion stimulant preparations for Periplaneta americana L


An improved structure and method are provided for increasing the operational bandwidth between different circuit devices, e.g. logic and memory chips, without requiring changes in current CMOS processing techniques. The structure includes the use of a silicon interposer. The silicon interposer can consist of recycled rejected wafers from the front-end semiconductor processing. Micro-machined vias are formed through the silicon interposer. The micro-machined vias include electrical contacts which couple various intergrated circuit devices located on the opposing surfaces of the silicon interposer.

The present invention relates generally to semiconductor integrated circuits. More particularly, it pertains to a structure and method for a high performance electronic packaging assembly.
Integrated circuit technology relies on transistors to formulate vast arrays of functional circuits. The complexity of these circuits requires the use of an ever increasing number of linked transistors. As the number of transistors required increases, the integrated circuitry dimensions shrink. One challenge in the semiconductor industry is to develop improved methods for electrically connecting and packaging circuit devices which are fabricated on the same and on different wafers or chips. It is an objective in the semiconductor industry to construct transistors which occupy less surface area on the silicon chip/die.
As integrated circuit technology progresses there is a growing desire for a xe2x80x9csystem on a chip.xe2x80x9d Ideally, a computing system would be fabricated with all the necessary integrated circuits on one wafer, as compared with today""s method of fabricating many chips of different functions and packaging them to assemble a complete system. Such a structure would greatly improve integrated circuit performance and provide higher bandwidth. In practice, it is very difficult with today""s technology to implement a truly high-performance xe2x80x9csystem on a chipxe2x80x9d because of vastly different fabrication processes and different manufacturing yields for the logic and memory circuits. Thus, what is needed is an improved method and structure which continues to approach the ideal set-up of a xe2x80x9csystem on a chipxe2x80x9d and thus improves the integration of different chips in an integrated circuit.
For the reasons stated above, and for other reasons stated below which will become apparent to those skilled in the art upon reading and understanding the present specification, it is desirable to develop a structure and method to increase the operational speeds, or data bandwidth, between different circuit devices, e.g. logic and memory chips. It is further desirable to attain this ability using current CMOS fabrication techniques.
The above mentioned problems with integrated circuits and other problems are addressed by the present invention and will be understood by reading and studying the following specification. A structure and method are provided to maximize the bandwith between different circuit devices.
In particular, an illustrative embodiment of the present invention includes an electronic packaging assembly. The electronic packaging assembly includes a silicon interposer which has a first and second side. At least one semiconductor chip is located on a first side of the silicon interposer. At least one semiconductor chip is located on a second side of the silicon interposer. A number of electrical connections exist through the silicon interposer which couple the semiconductor chips located on each side of the silicon interposer.
In another embodiment, an electronic system module is provided. The electronic system module includes a silicon interposer which has opposing surfaces. A microprocessor is included which has a circuit side. The circuit side of the microprocessor faces a first one of the opposing surfaces of the silicon interposer. A first memory chip is included which has a circuit side. The circuit side of the memory chip faces a second one of the opposing surfaces of the silicon interposer. Further, a number of electrical connections are provided which extend through the silicon interposer. The number of electrical connections couple the circuit side of the microprocessor to the circuit side of the first memory chip.
In another embodiment, a computer system is provided. The computer system includes an electronic packaging assembly. The electronic packaging assembly includes the electronic packaging assembly presented and described above. A number of external devices are included. A system bus couples the electronic packaging assembly to the number of external devices.
In another embodiment, a method for forming integrated circuits is provided. The method includes providing a silicon interposer which has opposing sides. A first semiconductor chip is coupled to a first side of the silicon interposer. A second semiconductor chip is coupled to a second side of the silicon interposer. The method further includes coupling the first semiconductor chip to the second semiconductor chip by means of electrical connections through the silicon interposer.
In an alternative embodiment, a method for forming integrated circuit is provided. The method includes providing a silicon interposer which has opposing sides. A number of micro-machined vias are formed through the silicon interposer. The micro-machined vias include a number of electrical connections between the opposing surfaces of the silicon interposer. A logic chip is coupled to the number of micro-machined vias on a first side of the silicon interposer. The method further includes coupling a memory chip to the number of micro-machined vias on a second side of the silicon interposer.
Thus, an improved structure and method are provided. The structure and method increase the operational bandwidth between different circuit devices, e.g. logic and memory chips, without requiring changes in current CMOS processing techniques. The structure includes the use of a silicon interposer. The silicon interposer can consist of recycled rejected wafers from the front-end semiconductor processing. This provides the added advantage of low cost and availability. A silicon interposer is thermally matched to the circuit devices such that coefficient of expansion mismatches are nonexistent. And, deposition of conductors on the silicon interposer""s surface is readily accomplished using a standard integrated circuit multi-layer metallurgy.
These and other embodiments, aspects, advantages, and features of the present invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art by reference to the following description of the invention and referenced drawings or by practice of the invention. The aspects, advantages, and features of the invention are realized and attained by means of the instrumentalities, procedures, and combinations particularly pointed out in the appended claims.

Structure and method for a high-performance electronic packaging assembly


A cutting blade assembly establishes a bidirectional and/or multifaceted scissor-type cutting action to efficiently and effectively process various types of debris encountered by the cutting blade assembly. The assembly includes a cutting plate and a cutting hub configured for relative rotation. A cutting slot is formed in the cutting plate and intersects the axial face to define a cutting edge at the intersection of the cutting slot and the axial face. The cutting hub has a cutting arm positioned adjacent to the axial face. When the cutting plate and the cutting hub undergo relative rotation, the cutting arm passes adjacent to the cutting edge to perform a scissor-type cutting action.

Cutting blade assemblies are used in a wide variety of applications to generally reduce the particle size of the medium being processed. Grinder pumps include a motor that rotates an impeller and an associated cutting blade assembly. Fluid and debris suspended within the fluid are drawn into the grinder pump where the cutting blade assembly attempts to reduce the particle size of the suspended debris before the impeller pumps the resulting slurry to a downstream location.
One issue common to most cutting blade assemblies, and especially those incorporated in a grinder pump or other fluid pumping applications, is the efficient processing and jam-free operation of the cutting blade assembly given the wide variety of debris encountered. For instance, with grinder pumps, debris including rags, mop heads, beverage containers, diapers, coins, and other objects can clog and jam the cutting blade assembly or place an increased load on the motor driving the cutting blade assembly. The various types of debris present many challenges because stringy debris (e.g., a mop head) can tend to wrap around the cutting blade assembly, resilient debris (e.g., plastic and rubber objects) can tend to wedge between moving parts of the cutting blade assembly, and hard debris (e.g., metallic objects) can wear or damage the cutting features of the cutting blade assembly.
To address these various problems associated with processing a variety of suspended debris, the drive motor torque can be increased, the cutting blade assembly strengthened, and the allowable particle size increased. However, none of these approaches presents an efficient, cohesive technique to address the persistent issues faced by cutting blade assemblies, and especially those cutting blade assemblies used in grinder pump applications.


An entirely mechanical air bag device for cars wherein a frangible lid seals a container having gas under pressure therein. The frangible lid is supported by a pressing lid in contact with a link mechanism. During a crash, an impact detecting assembly releases the link mechanism which in turn releases the pressing lid which permits the frangible lid to be fractured by the high pressure gas to inflate the bag.

1. Field of the Invention
This invention relates to air bag devices for automobiles whereby air bags can be entirely mechanically started.
More particularly, the invention relates to an air bag device wherein an opening part of a pressure gas container provided with an opening communicating with an air bag is tightly sealed with a frangible inner lid.
2. Description of Relevant Art
There is already known an air bag device for automobiles which detects the magnitude of an impact at the time of a collision of an automobile to start a gas generator in case the detected value is larger than a set value, to thereby inflate an air bag. The inflated air bag will reduce the impact to which the occupants are subjected, and the device will thus increase the safety of the automobile. Such an air bag device comprises an air bag, a gas generator, gas generation starting means, and impact detecting means.
Such known air bag device is generally of an electric fuse type which has many components and much wiring. The wiring and installation must be made very carefully and the cost is high. In addition, wiring breaks and circuit trouble are likely to occur at the time of a collision. Thus, there is also a problem in reliability.
Therefore, in an air bag device it is required that the device for starting the air bag should be activated at the time of a collision, and should have a structure as simple as possible. It should also have few parts, should be low in cost, should detect an impact, and should operate very quickly on the basis of a detected result. Also, it should inflate the air bag, should be positive in operation, should operate under any conditions, should be high in reliability, and should be able to be easily installed in an automobile by being assembled as a unit without requiring many pipings and wirings.
It is also preferable that the device be entirely mechanical while guaranteeing positive operation. It is also desirable that circuit trouble such as is caused by a long waiting period as in an electric type will not occur. There should be no delay and failure of the operation by the failure of the ignition due to hygroscopicity as in a type using a powder. There should be no need for inspection, replacement, and service of an impact detecting and transmitting system for preventing such delay and failure of operation.
It is also preferable that the gas generator should be so close that the operation of the detecting means may be transmitted directly to it to start the device.
It is also preferable that the device fitting space in the automobile should be as small as possible with respect to other mechanisms and parts. If there are many parts and pipes and wiring are required, a large space will be required. If the entire device including the piping and wiring fitting means and starting means is made large, it will not be easy to obtain the fitting space. It should not be necessary to alter the structure of the car body and to move and modify the instruments in the fitting, piping and wiring parts. Therefore, it is preferable to make the device small.


A device for attaching a tool in portable angled grinders, allowing the connection to be released without special accessories. The device consists essentially of a hollow driveshaft, of a spindle that slides inside it, and of a tool-securing point consisting of a mating flange and nut. The nut is loosened by activating the displacing mechanism, which displaces the spindle toward the tool-securing point, lifting the nut, which is connected to the spindle by means of a threaded pin, off of the tool. The nut can then be screwed off by hand.

The present invention relates to a device for attaching a tool in portable angled grinders, allowing the connection to be released without special accessories.
In order to replace the grinding disk in known angled grinders, the attaching flange, which is rigidly fastened to the grinding spindle, must be grasped with a special accessory. A mating flange, which is screwed onto the grinding spindle, can then be loosened with another accessory. This procedure is extremely inconvenient, entails the risk of severe injury, and is also very time-consuming.
German Pat. No. 2 926 469 accordingly proposes securing the grinding spindle with a mechanism that is integrated stationary into the drive-mechanism housing. The advantage of that solution is that only one accessory is needed, to loosen the mating flange. Still, the accessory for loosening the mating flange may often be out of reach, and the operator of an angled grinder of this type will be forced to look around for it. Since accessories often get lost, many attempts are made in practice to remove the tool by shear force, damaging the grinder. Furthermore, since the operator of a grinder of this type is not spared the necessity of carrying out a motion relative to the cutting edge of the tool with the hand that is holding the accessory, the risk of injury remains just as high as with the older type of grinder.
Another disadvantage to the tool disclosed in that German patent is the expense incurred in manufacture in order to prevent the grinder from being switched on unintentionally.


A constant velocity universals joint accepts rotary input through its axle and is also steered by a thrust bearing. A ball member having outward projections passes rotary motion to a surrounding socket member having cooperating inward projections which slidingly engage the ball projections. Both types of projections rotate about respective mountings. As the socket member turns in response to a steering input and the ball member maintains its orientation, the respective cooperating projections rotate about their mountings and slide across one another. The ball member thus continues to propel the socket member while accommodating variable angularity therebetween.

1. Field of the Invention
The present invention relates to constant velocity (CV) type universal joints, and more particularly, to a CV joint which accepts a rotary input and a separate steering input.
2. Description of the Prior Art
Universal joints designed to accept a steering input have been proposed in, among other sources, U.S. Pat. No. 1,188,854, issued to Thomas Spacie on Jun. 27, 1916, and U.K. Pat. Application No. 1,231,674, published on May 12, 1971. Both inventions disclose a joint having a substantially spherical inner member surrounded by a socket member. The sphere has projections configured to cooperate with the socket while accommodating relative motion therebetween.
CV type universal joints are exemplified by U.S. Pat. Nos. 397,976, issued to Riley R. Doan on Feb. 19, 1889; U.S. Pat. No. 1,297,968, issued to Fred H. Ream on Mar. 18, 1919; and U.S. Pat. No. 2,207,980, issued to Anton F. Greiner on Jul. 16, 1940. These patents disclose, generally, ball and socket construction, the ball having projections to engage the socket member while accommodating relative motion therebetween.
U.S. Pat. No. 5,042,608, issued to Satoru Hotlike et al. on Aug. 27, 1991, discloses a preferred application of the present invention, although not the structure.
None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.


An automatic performance apparatus output key data to different kinds of first and second internal or external sound sources and causes the first and second sound sources to synchronously generate tones. Key data is outputted to the first sound source after the lapse of a first delay time data is outputtted to the second sound source after the lapse of a second delay time. When the first sound source, which immediately starts tone generation in response to a tone generation instruction, and the second sound source, which starts tone generation with a delay time from the tone generation instruction, are caused to perform tone generation, a tone generation instruction to the first sound source is delayed from that to the second sound source, thus allowing synchronous musical tone generation between the two sound sources.

1. Field of the Invention
The present invention relates to an automatic performance apparatus using a plurality of sound sources and, more particularly, to a technique for controlling the sound sources to have synchronous tone generation start timings.
2. Prior Art
Conventionally, an automatic performance apparatus for driving a mechanical sound source, e.g., a pipe organ, a piano, or the like on the basis of key data (e.g., a key code and a tone generation timing) read out from, e.g., a memory, is known.
Another automatic performance apparatus for driving an electronic sound source of a waveform readout type or waveform synthesis type on the basis of key data read out from, e.g., a memory is also known.
Of the two kinds of sound sources described above, an electronic sound source starts generation of a musical tone immediately in response to a tone generation instruction. A mechanical sound source, e.g., a piano performs a mechanical operation, e.g., drives a hammer in accordance with a tone generation instruction. For this reason, the mechanical sound source starts tone generation with a delay time from the tone generation instruction.
When an automatic performance is performed using both the two kinds of sound sources, a tone generation start timing of the mechanical sound source is delayed from that of the electronic sound source in response to an identical tone generation instruction. For this reason, a good session effect cannot be obtained.

A method of manufacturing a ball valve member for cooperation with a valve and a ball valve member includes utilizing a cutting tool having first and second annular cutting surfaces with one of the cutting surfaces having a smaller radius than the other cutting surface whereby a slot is cut in the surface of the ball valve member to a greater depth than heretofore possible for permitting greater penetration of a valve stem into the ball valve member and a recess is formed adjacent the slot for the ball valve stem for receiving a lug member mounted on the stem to increase torque transmission to the ball valve element when the operation stem is rotated.

Ball valve members have long been in use especially in the field of gas and water distribution systems. In general, ball valve members have included a housing having an opening through which an operating stem is inserted to engage a surface slot or groove formed in a ball of the type having a through bore for movement into and out of alignment with conduits connected to the housing of the ball valve member. Internal seals engage the arcuate surface of the ball valve member to provide a secure seal over the life of the valve. However, it frequently happens that due to debris accumulating in and about the seals in the ball valve member, frozen liquid or the like, difficulty in rotating the ball valve through the operating stem engaged therewith has resulted in disconnection or breakage of the stem or the portion of the stem engaged in a slot formed in the surface of the ball valve.
While a number of attempted solutions have been proposed to increase the strength of the ball-stem connection, many of these have been relatively expensive to employ in a mass production facility or have proved impractical to adapt to a valve housing that has been prescribed by regulatory authorities.
In the past, the formation of the receiving slots in the surface of a ball valve member has been effected by use of a milling tool such as a key slot cutter or an end mill tool which is indexed to cut across the body of the ball valve to form a recess for cooperation with the tip of an operating stem. This was a time-consuming and labor-intensive operation which significantly contributed to the cost of the individual ball valve members.
With the operation of the present invention, the cost of manufacturing the ball valve for ready cooperation with an operating stem will be significantly reduced while significantly increasing the strength of the connection once effected.
The present invention provides an improved method of forming a ball valve member with a receiving slot whereby a connection with an operating stem can be effected that will be a stronger ball-stem connection yet less expensive than those connections utilized previously. In addition, a flow indicating feature is provided whereby a user will be readily able to determine the oriented condition of the ball valve member in establishing a connection with a stem either at the factory or in the field in an established fluid distribution system.
In a preferred embodiment, a cutting tool of the type having first and second annular cutting surfaces is employed where one of the annular surfaces has a reduced diameter relative to the other of the cutting surfaces. In carrying out the method of the present invention, the cutting tool is oriented generally perpendicularly to the through bore of the ball valve member and then is moved transversely to the ball valve surface to commence cutting a slot which has a longitudinal axis that extends perpendicular or parallel to the axis of the through bore. Cutting is continued until the second cutting surface which has a smaller radius than the first cutting surface engages and cuts a small recess adjacent to the slot for the operating stem. In some constructions, this will permit the main or first cutting surface to cut entirely through the thickness of the ball valve member to form an opening to the through bore of the ball valve but will always allow deeper penetration of the cutter than with the standard single cutter diameter.
With this arrangement, a much deeper penetration with a smaller diameter cutter of the ball member by the operating stem can be effected with a smaller diameter cutter, thus greatly increasing the strength of the connection between the operating stem and the ball valve member.
The foregoing and other advantages of this invention will become apparent to those skilled in this art as consideration is given to the following detailed description taken in conjunction with the accompanying drawings in which:

A masking for an engine block to be thermally sprayed with a coating includes a head deck mask portion adapted to engage a head deck of an engine block to prevent over-spray of a thermally sprayed coating on the head deck. The masking also includes a crankcase mask portion adapted to be disposed in a crankcase chamber of the engine block and engage a lower end of a cylinder bore cavity of the engine block to prevent over-spay of the thermally sprayed coating into the crankcase chamber.

1. Field of the Invention
The present invention relates generally to thermal spraying and, more specifically, to a masking for an engine block for thermally sprayed coatings and a method of masking engine blocks for thermally sprayed coatings.
2. Description of the Related Art
It is known to thermally spray articles. For example, thermal spraying has been used to provide a friction and wear resistance coating on cylinder bores of aluminum engine blocks. During the thermal spraying process, molten metal droplets are formed and sprayed in a relatively wide spray pattern at very high velocities from a spray nozzle of a thermal spray gun. The spray nozzle is stationed relatively close to a surface of the cylinder bore due to a restricted diameter of conventional cylinder bores (typically four to six inches). The combination of such high velocity and short travel distance will allow a small proportion of the particles to bounce or be deflected from the target surface resulting in over-spray. Such over-spray contaminates adjacent surfaces of the engine block not intended to be coated or such over-spray merely falls free of the engine block as waste material. The adjacent surfaces may be the crankcase chamber and support surfaces for the crankshaft. As a result, adequate masking must be provided to protect the crankcase and head deck of the engine block from errant particles that are generated during the thermal spray operation.
Early masking techniques used resilient or abatable plugs to protect apertures or holes of the components that are being thermally sprayed or painted. However, such plugs are not good for components having restricted access to the apertures and are a detriment when the interior of the apertures must not be penetrated or obscured to allow for proper spraying. Gases have also been used as a masking medium. Gases are blown across the interior side of a folded or curled sheet material to mask such side from a molten bath of metal into which the folded sheet is dipped. However, if such technique were to be used with thermal spraying of internal cavities, such gases would interfere with the thermal spray deposition.
Another technique to prevent over-spray is by masking cylinder bore extremities. An example of such masking is disclosed in U.S. Pat. No. 5,573,814 to Donovan. In this patent, a method of masking one or more extremities of a cylinder bore from internal thermal spraying is disclosed. The method includes the steps of supporting one or more inflatable mask members adjacent an end of the cylinder bore and pressurizing the inflatable mask member to expand and annularly engage the end of the cylinder bore. However, none of these techniques can be effectively used in an automated mass production environment practiced in the automotive industry.
Although the above method of masking for thermally sprayed articles has worked, it is desirable to improve the masking of engine blocks for thermally sprayed coatings. It is also desirable to provide a masking that accommodates all possible engine blocks and mask misalignments, provides adequate sealing and protects a crankcase and head deck of an engine block from thermal spray over-spray. It is further desirable to simplify the masking process for an engine block for spraying a thermally sprayed coating. It is still further desirable to provide a masking for an engine block that facilitates easy evacuation of the over-spray material and that is re-usable.
Accordingly, the present invention is a masking for an engine block to be thermally sprayed with a coating includes a head deck portion adapted to engage a head deck of an engine block to prevent over-spray of a thermally sprayed coating on the head deck. The masking also includes a crankcase portion adapted to be disposed in a crankcase chamber of the engine block and engage a lower end of a cylinder bore cavity of the engine block to prevent over-spray of the thermally sprayed coating into the crankcase chamber.
Also, the present invention is a method of masking an engine block for thermally spraying a coating. The method includes the steps of providing an engine block to be thermally sprayed and providing a head deck masking for masking a head deck of the engine block. The method also includes the steps of providing a crankcase masking for masking a portion of a crankcase chamber of the engine block, disposing the crankcase masking in the crankcase chamber and engaging the crankcase masking with a lower end of a cylinder bore cavity of the engine block. The method further includes the steps of engaging the head deck masking against the head deck of the engine block. The masking prevents over-spray of a coating that is thermally sprayed on a wall of the cylinder bore cavity of the engine block, from adhering to the head deck and entering the crankcase chamber.
One advantage of the present invention is that a masking for and method of masking an engine block for thermally sprayed coatings is provided. Another advantage of the present invention is that the method and masking protect the crankcase from misalignment and over-spray during thermal spraying. Yet another advantage of the present invention is that the method and masking incorporate high temperature rubber with aluminum. Still another advantage of the present invention is that the masking provides adequate stiffness and sealing in selected areas of the engine block, allowing easy evacuation of the over-spray and preventing hot thermal spray particles from adhering to the engine block during coating operation.
Other features and advantages of the present invention will be readily appreciated, as the same becomes better understood, after reading the subsequent description taken in conjunction with the accompanying drawings.

a. Field of the Invention
This invention relates to 11(eq)-substituted-2,6-methano-3-benzazocines useful as analgesics and narcotic antagonists.
b. Description of the Prior Art
2,6-Methano-3-benzazocines substituted in the 11-position with a lower-alkyl group are known. (See for example Gordon et al. U.S. Pat. No. 2,924,603, patented Feb. 9, 1960). Moreover, it is known that compounds in the 5,14-endo-etheno- and ethanotetrahydrooripavine series having ketone, carbinol or lower-alkenyl groups at the 7-position thereof have unusual analgesic potency relative to morphine. [See Bentley et al., J. Am. Chem. Soc. 89, 3267-3292 (1967)]. Consequently there has been much interest in the field of analgesics in incorporating the ketone, carbinol or lower-alkenyl function present in the latter series at the 11-position of 2,6-methano-3-benzazocine-type analgesics, but all synthetic efforts in this direction have previously been unsuccessful.

A mail sorting system is provided which includes a plurality of mail sorters and coding devices. These mail sorters and coding devices are selectively coupled together by a distributor so that any coding device can be coupled to any mail sorter. When a mail sorter cannot identify the zip code of a particular piece of mail, the unrecognized address image is transferred to one of the coding devices so that the correct address can be input by an operator. An assigning controller is connected to the distributor for determining which coding device should receive the unrecognized address image in accordance with the current mail processing capability of the mail sorters and coding devices in order to maximize the mail handling capability of the mail sorting system.

This invention relates to a mail sorting system, more particularly, a mail sorting system provided with a plurality of mail sorters and coding devices.
Various types of automatic mail sorting devices have been proposed in order to save labor in mailing services. One known type of mail sorter is described, for example, in European Patent Application EP No. 0 066 186. This mail sorter includes a reading device for obtaining a zip code image or an address printed on postal matter such as letters, cards or periodical mail, a recognition unit for determining the destination of the postal matter upon recognition of the image and a sorting device for delivering the postal matter to stacking bins on sorting shelves in accordance with the destination determined by the recognition unit.
Another type of known mail handling device uses coding equipment as described, for example, in British Pat. No. GB 2 066 018. This coding equipment includes the reading device described above for obtaining images of the postal matter but does not include a recognition unit. Instead, one or more coding stations or coding devices are provided which comprise a monitor and keyboard. Successive images are displayed on the monitor so that the operator, upon watching the monitor, can input the proper zip code or area code on the keyboard.
The described coding equipment is more reliable than the formerly described sorting devices because available recognition units cannot yet get a recognition rate of 100%. When recognition units cannot recognize the zip code, the mail is rejected and delivered to a special stacking bin, which must be manually sorted at a later time. However, the disadvantage of coding equipment is that it requires more labor and can sometimes attain less performance than sorting devices with recognition units.
In recent years, with the large increase in the amount of mail, mail sorting machines that can handle large quantities of mail without much labor are desired. One proposed solution has been to install several mail sorters and operate them in parallel. However, in such a parallel system, the amount of rejected mail in each mail sorter increases and different types of rejections occur in different mail sorters. Also, over time, variations in the amount of mail handled by each sorter occur in response to the quality of zip code or address information.


A camera dolly has a track wheel system including a kingpin pivotally supported on a dolly chassis. A kingpin tube extends laterally from the kingpin. An axle is pivotally supported within the tube on pins. A track wheel around a bearing is supported on a bushing on the axle. A knob unit threaded into the axle may be turned into a locked position wherein the track wheel is supported as in a conventional axle. For use on curved track, the knob unit is released or backed out, allowing the track wheel to shift laterally, to accommodate moving on curved dolly track, and to allow the wheel to steer on the track at a proper steering angle, by pivoting on the pins.

The field of the invention is camera dollies.
Camera dollies are used in the television and motion picture industries to support and maneuver a camera. Typically, the camera dolly is on wheels and has an arm to raise and lower the camera. The camera dolly is generally moved by dolly operators or "grips", to properly position the camera to follow the film or video sequence.
The camera dolly must support and maneuver the camera with a minimum of vibration or shock, to avoid degrading the filmed image quality. Consequently, camera dollies must be designed, manufactured and maintained with precision. When used on a relatively smooth surface, such as studio floor, the camera dolly is generally supplied with pneumatic tires, so that the camera may be smoothly supported and moved, even over minor cracks or bumps in the floor surface.
When the supporting ground surface is bumpy and irregular (e.g., when the dolly is used outdoors on sand, irregular ground, a poor quality paved surface, etc.,) track is assembled on the ground to provide a smooth rolling surface for the dolly. However, for use on track, many dollies require that the pneumatic ground wheels be replaced with stiffer track wheels. Other camera dollies require the installation of track wheel attachments, which are provided as accessories to the dolly. While these techniques have met with varying degrees of success, they have certain disadvantages. For example, it may be time consuming and labor intensive to install track wheels. During production of a motion picture or television program, even a delay of e.g., five minutes, (to install track wheels) can be very costly as all of the actors, camera operators, lighting, sound and special effects professionals, the director and the various crew members must wait until the camera dolly is set up for the track filming sequence. Accordingly, it is advantageous to have equipment which can be quickly set up for the desired film or video sequence. In addition, track wheels or track wheel attachments must be shipped and stored separately from the camera dolly, since they are not permanently attached to the dolly. This requirement further complicates the logistics of television and film production.
Where a camera dolly is moved over curved track, the lateral spacing between the left and right wheels (or sets of wheels) must be allowed to change slightly, to accommodate the wheel position geometry on curved track. In addition, the wheel (or wheel sets) on the inside of the curve must be turned or angled more sharply than the outside wheels. These requirements must be accommodated for good dolly performance, and they complicate dolly design considerations.
Accordingly, there is a need for an improved track wheel system for a camera dolly.
Other and further objects and advantages of the invention will become apparent hereinafter.
