A method for producing articles from iridium metal nanopowder. This invention relates to the sphere of powder metallurgy and may find application in the production of different articles from iridium. Technically, the object of the invention is development of a new technology. To this aim a method is proposed for the production of articles from iridium based on use of chemically pure metal of not less than 99.99 purity, produced by electron-beam remelting, characterized in that the required material is turned to nanopowder of less than 100 nm dispersity from which seamless articles of various configuration are molded by their compacting at room temperature followed by baking, with the resulting isotropic structure featuring 100-300 nm grain size and strength characteristics being improved by 200-300%.

Iridium is a refractory platinum-group metal. The combination of such properties as high melting point and the highest among metals unreactiveness make this metal an indispensable structural materials for operation under conditions of elevated temperatures (up to 2200° C.) and aggressive environments. This is the only metal from which special application articles are manufactured, such as:
crucibles for growing large oxide monocrystals used in microelectronics and laser technology;
rolled stock for the manufacture of small-size nuclear reactor pressure vessels and containers for plutonium dioxide-based thermoelectric generators for interplanetary space flights;
disks for the manufacture of radioisotope sources for use in non-destructive testing instruments and in oncological diseases treatment;
wire for the manufacture of thermocouples for not less than 2200° C. measured temperatures range;
electrodes for motor vehicle spark plugs ensuring over 250 thousand kilometers of vehicle run.
The worldwide demand for iridium articles in 2014 grew four times to reach 10.5 tons, with a 2.5-times increase in the price for iridium. Steady industrial demand for iridium products is a factor preserving stability of prices at the present time as well.
The major problem in the manufacture of products from iridium is high sensitivity of this metal processing and service characteristics to presence of most insignificant quantities of impurity elements, which appear to be the principal cause of brittle failure of iridium. According to the traditional technology of manufacture of iridium articles, the blanks used in the production of iridium rolled stock present iridium monocrystals with impurities content not exceeding 0.003% obtained in the process of preliminary multi-stage energy-consuming fire refining with the use of electron-beam remelting (EBR) under vacuum. The industrial technology of production of this metal is available to a limited number of manufacturers, among them such companies as: Johnson Matthey PLC (UK), W.C. Heraeus GmbH (Germany), the Oak Ridge National Laboratory (USA), Engelhard-CLAL Corporation (USA), OAO Ekaterinburg Non-Ferrous Metals Treatment Plant and ZAO URALINTEKH (Russia).
High-purity iridium metal nanopowder (MINP) is designed for creation of new structural materials with a set of targeted physical-chemical and application properties, offering an opportunity for development of principally new efficient processes for the manufacture of articles with improved service characteristics.
MINP was generated as a result of an original combination of hydrometallurgical, electrochemical and fire refining processes; it presents black particles of 99.990% chemically pure metal 20-70 nanometers in size, with surface area within 3-7 m2/g and powder bulk density of 0.4-0.9 g/cm2. The metal is thermally stable at up to 200° C. in air, and non-pyrophoric.
As compared with the industrial iridium powders of home and foreign manufacture, the proposed MINP exceeds them by an order of magnitude in chemical purity, 5 to 10 times in powder bulk density characterizing unit mass consumption per unit volume, and 200 to 400 times in surface area characterizing catalytic activity.
Processes under development in the USA include deposition of a coat of iridium on articles operating under rigorous service conditions, on rocket nozzles in particular. A refractory corrosion-resistant coating of the working surfaces of a combustion chamber and a rocket-thrust-chamber nozzle will allow temperature rise from 1300° C. (current engines) to 2000-2100° C., resulting in increased fuel efficiency and useful load (see www.fazwest.com).
To this aim, the chemical vapor deposition method (CVD) with the use of complex organic iridium compounds was earlier selected; however the process of production of these metalorganic compounds is expensive since it requires special synthesis conditions, and the CVD process proper with the use of these compounds is found hard to localize in the target zone. For this reason, 70-80% of iridium is assimilated by chamber walls, and only 20-30% being deposited on the target surface.
There is a known technology of manufacture of iridium crucibles (see Timofeev N. I., Yeramakov A. V., Dmitriev V. A., Panfilov P. E. Osnovy metallurgii i tekhnologii proizvodstva izdelii iz iridiya (Basic metallurgy and process for production of articles from iridium). Ekaterinburg: UB RAS, 1996.—prototype) comprising the following operations:
production of metal compact by pressing initial powder, GOST 12338-81;
induction oxidizing melting in periclase crucible;
autoclaving;
ingot swaging;
electron-beam vacuum melting in horizontal mold;
electron-beam non-crucible zone melting, monocrystal growing;
swaging (2000-1100° C.), production of sheet bar;
boiling in chloronitric acid;
rolling (1000-800° C.), production of plate;
boiling in chloronitric acid;
manufacture of crucible shell ring (600-800° C.);
boiling in hydrochloric acid;
shell ring welding and its welding to bottom;
crucible annealing at 1100° C.;
polishing.
Metal yield in a finished article is 60-65% with up to 1.3% irrecoverable loss.
Drawbacks: great number of operations, low finished product yield and high production cost.

A mounting structure of a door basket for a refrigerator is provided. The mounting structure includes a door liner, which defines a rear surface of a door and includes at least one slot that is formed from side to side by recessing a portion of an outer surface of the door liner, a slot cover configured to protect at least one outward projection, which is formed on a rear surface of the door liner by forming the slot, from a pressure of foam for forming an insulating layer, and a door basket, in which a storage space is formed, and which is provided with at least one mounting projection which is inserted into the slot and then slides from side to side. Since the slot cover prevents the slot from being deformed during a foaming process for forming the isolating layer within the door, it is possible to reduce the defective rate of the product and to minimize a thickness of the door liner, which makes it possible to reduce production costs.

1. Field of Invention
The present invention relates to a refrigerator, and more particularly, to a mounting structure of a door basket which can be mounted to a rear surface of a door of a refrigerator to move from side to side along the rear surface.
2. Description of the Prior Art
FIGS. 1a and 1b show a mounting structure of a door basket according to a prior art. Referring to the figures, a door 10, which selectively opens and closes a storage space (not shown) of a refrigerator, comprises an external appearance plate 11 defining external appearances of front, side, upper, and lower surfaces of the door and a door liner 13 defining an external appearance of a rear surface of the door. An insulating layer 14 is formed between the external appearance plate 11 and the door liner 13. The insulating layer 14 is formed from foamed polyurethane.
A pair of forward protruding projections 15 are formed vertically at both side ends of an outer surface of the door liner 13 corresponding to the rear surface of the door 10. In addition, a plurality of slots 17 are formed from side to side between the projections 15. Each of the slots 17 is formed by recessing a portion of the door liner 13. Further, a pair of the slots 17 are provided at upper and lower portions on the outer surface of the door liner 13, respectively. Since an inlet 17a of each slot 17 is formed to be relatively narrower than an interior 17b thereof, mounting projections 23, which will be described bellow, are inserted into the slots 17, and then, are not detached to the outside.
A door basket 20, which is mounted onto the outer surface of the door liner 13 and in which a storage space 21 is formed, is formed from side to side. A length from side to side of the door basket 20 is formed to be shorter than an interval between the projections 15. A rear surface of the door basket 20 is provided with a plurality of the mounting projections 23 and 23′ which cause the door basket 20 to be mounted to the door liner 13.
A pair of the mounting projections 23 and 23′ protrude rearward from and are provided at upper and lower portions on the rear surface of the door basket 20 in two rows. Preferably, two pairs of the mounting projections 23 and 23′ are provided at the upper and lower portions of the rear surface of the door basket 20, so that there are provided at least four mounting projections. The upper mounting projection 23 is press fitted into the inlet 17a of the upper slot 17, while the lower mounting projections 23′ is brought into contact with a ceiling in the lower slot 17 to serve to support load of the door basket 20. The door basket 20 including the mounting projection 23 or the mounting projection 23 may be formed of material having predetermined elasticity.
However, the mounting structure of the door basket for the refrigerator according to the above prior art has the following problems.
That is, in a manufacturing process of the door 10, a space between the external appearance plate 11 and the door liner 13 is filled with foam liquid. Here, due to a pressure of the foam liquid, a shape of the slot 17 is deformed, as shown in FIG. 2.
If the slot 17 is deformed as above, it is not easy for the mounting projection 23 to be inserted into the slot 17. Furthermore, with the mounting projection 23 being inserted into the slot 17, the door basket 20 cannot slide from side to side, causing the articles to be defective.
In order to solve the above problems, the thickness of the door liner 13 can be increased above the value capable of resisting the pressure generated from the foam liquid. However, if the thickness of the door liner 13 increases, the production costs thereof also increase. Furthermore, since there is a limit in increasing the thickness of the door liner 13, the increase of the thickness of the door liner is not effective in preventing the slot 17 from being deformed.

Display units for products such as eyeglass frames and including a frame and apparatus for adjustably supporting a plurality of eyeglass display shelves. The apparatus for supporting display shelves includes a cable assembly having a plurality of vertical cables, each vertical cable being supported by the display device frame, and a plurality of shelves suspended from the cables such that the position of the shelves can be readily adjusted.

In clinics and retail establishments of the type selling eyeglasses and frames for eyeglasses, the frames are commonly supported on wall mounted shelving or in floor mounted cases. These display devices frequently do not provide for efficient use of retail space and may not provide attractive display areas if the geometry of the display space is not suited specifically for retail sales of eyeglass frames. Additionally, retail space used for optical clinics and retail establishments selling eyeglasses frequently may not have sufficient wall space suitable for displaying sufficient numbers of eyeglass frames, or may not permit attractive display of the eyeglass frames. The retail space may also have large central open areas not useful for display of eyeglass frames, or the space may otherwise be of a geometry which makes attractive display of the eyeglass frames difficult. Additionally, wall mounted display shelves may be time consuming to install and are not conveniently moved from one retail establishment to the other.
In other applications, shelving has been supported by cables or rods having upper ends anchored to a ceiling and with lower ends anchored to the floor. Such shelving systems are distributed by Mobile Cable Systems, Northfield, Ill. and are described in a catalog titled The Function of Our Form is to Disappear.

Suspension system for displaying eyeglass frames


A system for and method of tracking and locating RFID tags, including where at least one steerable phase array antenna may locate the tags associated with items in three dimensions in real time, through the use of a beam steering unit and controller therewith to control the direction of a beam launched by the at least one steerable phase array antenna.

Conventional RFID readers can read tags at distances less than desired by the RFID tag user. Multiple RFID tags in a particular location or volume, such as a warehouse, are inherently difficult to locate or track. When RFID tags are in proximity to one another (the proximity varying, for example, due to RFID tag type or conditions within the space in which they are located or conditions in the surrounding space or both), that is a multipath environment, conventional RFID readers cannot locate the RFID tags with acceptable precision. Furthermore, conventional systems cannot track the three dimensional movement of RFID tags with any precision, if at all.
Therefore, it is an object of the invention to provide a system and method(s) that overcomes deficiencies in the prior art.

This patent is subject to a terminal disclaimer.

In a boat having a seat, a steering wheel, and an outboard motor, an outboard motor steering system is provided, where the steering wheel is installed near the seat a steering angle sensor installed near the steering wheel for outputting a signal indicative of a steering angle of the steering wheel. The steering system also includes a swivel shaft connected to a propeller to turn the propeller relative to the boat, and an electric motor connected to the swivel shaft for rotating the swivel shaft in response to the detected steering angle. The steering system also includes a manipulation load regulation mechanism, such as a hydraulic damper, to produce an added load for increasing a manipulation load of the steering wheel, thereby enabling reduced operator load by using the electric motor to steer the outboard motor, while improving the operator's feel of steering wheel manipulation.

1. Field of the Invention
This invention relates to an outboard motor steering system.
2. Description of the Related Art
In recent years, technologies have been developed that reduce the burden on the operator of an outboard motor driven boat by enabling steering of the outboard motor using an actuator connected to the motor. Steering systems of this type generally use a sensor to detect the steering angle of a steering wheel provided on the hull (boat) and drive the steering actuator based on the detected value, as taught, for example, in Japanese Laid-Open Patent Application No. 2002-187597, paragraphs 0011, 0025 and 0027 and FIG. 1.
Such a prior art steering system that steers an outboard motor using an actuator completely cut off mechanical interconnection between the steering wheel and the outboard motor. This results in such an excessive reduction in steering wheel manipulation load that the operator may be dissatisfied with the operating feel.


Briefly, in one embodiment, a method for enhancing aggregate data throughput for a number of wireless devices. First, a signal having a first level of effective isotropic radiated power is transmitted by a first wireless electronic device. In the event that a response to the signal is received by the first wireless electronic device, the level of effective isotropic radiated power is reduced to a second level of effective isotropic radiated power. In another embodiment, the aggregate amount of data throughput may be enhanced by monitoring a level of effective isotropic radiated power associated with at least one beacon produced by the first wireless electronic device on a first communication channel. The level of effective isotropic radiated power of the beacon is then reduced if the monitored level is greater than a predetermined power level threshold.

The ability of users to access programs and share data over local area networks (referred to as "LANs") has become a necessity for most working environments. To improve efficiency and ease of use, certain enhancements may be added to a LAN such as remote wireless access. By providing wireless access, a wireless LAN (WLAN) is formed.
As described in U.S. Pat. No. 5,987,062 issued to Netwave Technologies, Inc., now owned by Nortel Networks Limited, one type of WLAN employs dedicated stations, which are referred to as access points (APs). Therein, each AP is a relay station that includes a radio frequency (RF) transceiver that receives (and transmits) radio data packets over a communication channel from (and to) mobile units within a predetermined, non-adjustable coverage distance. The level of effective isotropic radiated power used by the RF transceiver determines the coverage distance. An example of this AP is a BAYSTACK™ 650 Wireless Access Point produced by Nortel Networks Limited.
Hence, depending on the coverage distance, an AP can share its communication channel with tens or even hundreds of mobile units. This reduces the aggregate amount of data throughput to the mobile units. To improve data throughput, one proposed solution is to implement additional APs within the WLAN. However, this proposed solution may not be applicable, depending on the operating environment.
For example, in order to effectively reuse communication channel frequencies within a WLAN, each additional AP must be placed outside a pollution range associated with its neighboring AP. This "pollution range" is the coverage area determined by both the coverage distance of the AP as well as the coverage distance of any of its mobile units because they communicate on the same communication channel. For a worst case scenario, where the level of effective isotropic radiated power used by the mobile unit is equivalent to the level of effective isotropic radiated power used by the AP, the pollution range is twice the coverage distance, and thus, a maximum of four times the coverage area of the AP. Hence, the additional placement of APs may not be a legitimate solution to data rate throughput problems for a WLAN when there is a high concentration of mobile units within a small area.

Dynamic power level control on transmitted messages in a wireless LAN


A power supply assembly for a terminal having Ethernet energy supply, includes a split device with an Ethernet energy supply connection (A1) that connects to an Ethernet cable which is set up to supply energy and with an output to provide a first DC voltage (U1), a logic unit coupled to the split device, a DC/DC converter coupled to the logic unit and connected to the output of the split device in a switchable manner, and a voltage (U) that supplies the terminal being provided at an output of the DC/DC converter under control of the logic unit.

Attempts are currently being made to also supply devices connected to a data network with energy via the data network. A conventional standard for this purpose is, for example, IEEE 802.3 of for the so-called Power over Ethernet. In the case of "Power over" Ethernet, network-compatible devices are supplied with energy via the eight-wire Ethernet cable. One advantage of Power over Ethernet is that it is possible to dispense with a power supply cable in the device.
To expand a terminal with Power over Ethernet functionality, a so-called "splitter" is usually installed in a conventional Ethernet-compatible terminal. This splitter separates the energy provided via the Ethernet cable from the data. The splitter thus generates a DC voltage and provides the Ethernet signal. In this case, the DC voltage is in a region of 50 V according to the standard. Consequently, this DC voltage must then be converted into a supply voltage of 3 to 12 V, for example, which is typically conventional for terminals. This increases the complexity, costs, susceptibility to faults, weight and area and space requirement of the power supply in the terminal.
Therefore, it could be helpful to further improve a power supply for terminals having Ethernet energy supply.

The actuator has a rod portion having a tip end, located at first end of the actuator, said tip end pivotably attach to a control surface of an aircraft. The link includes a pair of linear portions, each having first and second opposing ends, wherein the linear portions are disposed alongside each other; a coupling portion connecting the first ends of linear portions, a fulcrum shaft attachment portion protruding from the coupling portion configured to pivotably attach to a fulcrum shaft for rotatably supporting the control surface; and an actuator attachment portion configured to pivotably attach to the second end of the actuator. A material constituting the linear portions and the coupling portion contains fiber reinforced plastic.

1. Field of the Invention
The present invention relates to an actuator-link assembly including an actuator that can be attached to a control surface of an aircraft or to a horn arm member in order to drive the control surface, and a link that is connected to the actuator, a manufacturing method for manufacturing the actuator-link assembly, and a designing method for designing the actuator-link assembly.
2. Description of Related Art
An aircraft is provided with control surfaces that are formed as moving surfaces (flight control surfaces) and are configured as an aileron, a rudder, an elevator, and the like. As an actuator for driving such a control surface and a link that is connected to this actuator, those disclosed in JP H5-97095A and JP S62-165007A are known. With the actuator-link assemblies disclosed in JP H5-97095A and JP S62-165007A, the actuators are provided as a hydraulically driven cylinder mechanism that can be attached to a control surface or a horn arm member attached to the control surface, and the links are coupled pivotably to the actuator and the control surface.
The actuator-link assemblies for driving a control surface of an aircraft as disclosed in JP H5-97095A and JP S62-165007A are required to have high strength in order to support the load for driving the control surface, and are also required to have high rigidity from the viewpoint of suppressing the deformation and ensuring the stability as the control systems for driving the control surface. For this reason, when the actuator-link assemblies as disclosed in JP H5-97095A and JP S62-165007A are designed and also when they are manufactured, a metallic material such as stainless steel or a titanium alloy can be selected as the material constituting the actuator-link assemblies from the viewpoint of ensuring the required strength and rigidity. However, since the actuator-link assemblies are made of a metallic material, there is a limit to their weight reduction, and it is difficult to achieve further weight reduction in the current situation.
When a titanium alloy is used as the material constituting an actuator-link assembly, a high specific rigidity, which is the rigidity per unit weight, can be ensured, but the specific strength, which is the strength per unit weight, is reduced. For this reason, ensuring the strength becomes a constraint, making it difficult to achieve weight reduction. On the other hand, when stainless steel is used as the material constituting an actuator-link assembly, a high specific strength can be ensured, but the specific rigidity is reduced. For this reason, ensuring the rigidity becomes a constraint, making it difficult to achieve weight reduction.
Therefore, in order to provide an actuator-link assembly that can ensure strength and rigidity in good balance and achieve weight reduction, it is necessary to design the structure of an actuator-link assembly from a point of view that is completely different from that of conventional technology. Also, in addition to achieving weight reduction, it is necessary to ensure strength and rigidity that are equivalent to or greater than those achieved by the conventional technology.

A vehicular headlamp includes: a first light source module having semiconductor light emitting elements; a first optical member for applying light generated by the first light source module to an area of the light distribution pattern of the vehicular headlamp; a second light source module that has semiconductor light emitting elements and generates light having the brightness higher than that of the light of the first light source module; and a second optical member for applying the light generated by the second light source module to an area narrower than the area to which the light is applied by the first optical member.

1. Field of the Invention
The present invention relates to a vehicular headlamp and a car headlamp. Particularly, the present invention relates to a headlamp used for a vehicle and a headlamp used for a car.
2. Description of the Related Art
In recent years, a lighting device for a vehicle that employs a semiconductor light emitting element such as an LED (Light Emitting Diode) has been known (for instance, see JP-A-2002-231013 (pages 2 to 6, FIGS. 1-13)). Further, it has been studied to use the semiconductor light emitting element such as the LED for a vehicular headlamp, for instance, in view of design. The vehicular headlamp needs to form a prescribed light distribution pattern from the viewpoint of safety. A light distribution pattern includes an area called a hot zone to be irradiated with light more brightly than other areas in the light distribution pattern.
In order to brightly irradiate the hot zone with light, a light source of high brightness is preferably used to condense the light having high luminous intensity to the hot zone and irradiate the hot zone with the light. To generate the light of the high brightness, the light source may allow the light having a large light flux to be generated. However, when a semiconductor light emitting element such as an LED generates the light having the large light flux, a light emitting efficiency may be sometimes deteriorated. Accordingly, the consumed power of a vehicular headlamp is undesirably increased.


A method and apparatus to enable data integrity checking of a block of data while the block of data is being transferred from a volatile memory to a non-volatile storage device is provided. The data integrity checking is performed in conjunction with Direct Memory Access operations and Redundant Array of Independent Disk (RAID) operations. In addition, data integrity checking of syndrome blocks in the RAID is performed during transfers to/from the storage devices in the RAID system and during RAID update and RAID data reconstruction operations.

A Redundant Array of Independent Disks (RAID) combines a plurality of physical hard disk drives into a logical drive for purposes of reliability, capacity, or performance. Thus, instead of multiple physical hard disk drives, an operating system sees the single logical drive. As is well known to those skilled in the art, there are many standard methods referred to as RAID levels for distributing data across the physical hard disk drives in a RAID system.
For example, in a level 0 RAID system the data is striped across a physical array of hard disk drives by breaking the data into blocks and writing each block to a separate hard disk drive. Input/Output (I/O) performance is improved by spreading the load across many hard disk drives. Although a level 0 RAID improves I/O performance, it does not provide redundancy because if one hard disk drive fails, data is lost
A level 5 RAID system provides a high level of redundancy by striping both data and parity information across at least three disk drives. Data striping is combined with parity to provide a recovery path in case of failure. A level 6 RAID system provides an even higher level of redundancy than a level 5 RAID system by enabling recovery from double disk failures.
In a level 6 RAID system, two syndromes referred to as the P syndrome and the Q syndrome are generated for the data and stored on disk drives in the RAID system. The P syndrome is generated by simply computing parity information for the data (data blocks (strips)) in a stripe (data blocks (strips), P syndrome block and Q syndrome block). The generation of the Q syndrome requires Galois Field (GF) multiplications and is a more complex computation. The regeneration scheme to recover data and/or P syndrome block and/or Q syndrome block performed during disk recovery operations requires both GF and inverse operations.
The generation and recovery of the P and Q syndrome blocks for RAID 6 and parity for RAID 5 requires the movement of large blocks of data between system memory and a storage device (I/O device). Typically, an Input Output (I/O) Controller (IOC) in a computer system includes a Direct Memory Access (DMA) controller (engine) to perform transfers of data between memory and the I/O device. The computer system can also include a DMA controller used for memory to memory data transfers. A DMA controller allows a computer system to access memory independently of the processor (core). The processor initiates a transfer of data from a source (memory or I/O device (controller)) to a destination (memory or I/O device (controller)) by issuing a data transfer request to the DMA controller. The DMA controller performs the transfer while the processor performs other tasks. The DMA controller notifies the processor, for example, through an interrupt when the transfer is complete. Typically, a DMA controller manages a plurality of independent DMA channels, each of which can concurrently perform one or more data transfers between a source and a destination.
Typically, a data transfer from a source to a destination is specified through the use of a descriptor, that is, a data structure stored in memory that stores variables that define the DMA data transfer. For example, the variables can include a source address (where the data to be transferred is stored in the source (memory (or I/O device)); size (how much data to transfer) and a destination address (where the transferred data is to be stored in the destination (memory (or I/O device)). The use of descriptors instead of having the processor write the variables directly to registers in the DMA controller prior to each DMA data transfer operation allows chaining of multiple DMA requests using a chain of descriptors. The chain of descriptors allows the DMA controller to automatically set up and start another DMA data transfer defined by a next descriptor in the chain of descriptors after the current DMA data transfer is complete.
Although the following Detailed Description will proceed with reference being made to illustrative embodiments of the claimed subject matter, many alternatives, modifications, and variations thereof will be apparent to those skilled in the art. Accordingly, it is intended that the claimed subject matter be viewed broadly, and be defined only as set forth in the accompanying claims.

Method and apparatus for increasing data reliability for raid operations


An apparatus adaptable for use with an analog-digital conversion device for effecting communications between an analog device and a digital device, the analog-digital conversion device converting incoming analog signals received from the analog device to incoming digital signals. The apparatus has a digital signal processing circuit for decimating the incoming digital signals and providing a decimated incoming digital signal to the digital device.. The digital signal processing circuit is comprised of a plurality of modules which are configured so that a specified set of the plurality of modules effects a specified number of iterations of decimation. The modules are further designed so that additional modules may be added to the specified set of modules to increase the iterations of decimation.

The present invention is directed to a communications interface apparatus adaptable for use with an analog-digital conversion device for effecting communications between an analog device and a digital device. Specifically, in its preferred embodiment, the present invention is used in effecting communications between a voice-band device, such as a telephone, and a data processing device.
The present invention receives digital signals from an analog-digital conversion device, decimates those incoming digital signals to produce decimated incoming digital signals representative of the received incoming digital signals. The decimated incoming digital signals are recognizable by the data processing device.
In the manufacturing of interface devices such as the present invention, separate circuit designs are often utilized to effect different numbers of iterations of decimation of signals produced by analog-to-digital conversion circuitry. Often there is duplication of engineering effort in designing such variously capable decimation circuitry.
Such duplicate engineering effort results in each newly designed digital signal processing circuit involving essentially as much design effort, and cost, as a wholly new circuit.
The present invention is designed to overcome some of the expense of duplication of engineering effort to design variously capable digital signal processing circuits.

Apparatus having a modular decimation architecture


Disclosed is a composition comprising about from 20 to 65 percent by weight of a fiber reinforcing-agent, preferably glass fiber, dispersed in as-polymerized propylene polymer material, e.g., propylene homopolymer, having a melt flow rate (MFR) of about from 55 to 430 dg/min. The composition is useful in the manufacture of large and complex fiber-reinforced articles and parts by injection molding.

The synthetic resin formed by the polymerization of propylene as the sole monomer is called polypropylene. While "polypropylene" has been used from time to time in the art to include a copolymer of propylene and a minor amount of another monomer, such as ethylene, the term is not so used herein.
The polypropylene of commerce is a normally solid, predominantly isotactic, semi-crystalline, thermoplastic polymer mixture formed by the polymerization of propylene by Ziegler-Natta catalysis. In such catalysis the catalyst is formed from an organic compound of a metal of Groups I-III of the Periodic Table, such as an aluminum alkyl, and a compound of a transition metal of Groups IV-VIII of the Periodic Table, such as a titanium halide. Typically the crystallinity of polypropylene thus produced is about 60% as measured by X-ray diffraction. As used herein, "semi-crystalline" means a crystallinity of at least about 5-10% as measured by X-ray diffraction. Also, the typical weight average molecular weight (Mw) of the normally solid polypropylene of commerce is 100,000-4,000,000, while the typical number average molecular weight (Mn) thereof is 25,000-600,000. The typical molecular weight distribution or polydispersity is about from 4 to 7. The typical melt flow rate (MFR) of most of the normally solid polypropylenes of commerce as-polymerized has ranged from less than 1 to about 20 dg/min as determined by ASTM D 1238. Most commonly, the melt flow rate is about 4 dg/min. Over about the last five years, polypropylenes having a melt flow rate, as-polymerized, of about 20 dg/min have become available. In the last half of 1986, a normally solid polypropylene was made commercially available having an as-polymerized MFR of from about 55 to about 430 dg/min, and weight average and number average molecular weight such that its polydispersity is about 4-5.
Fiber-reinforced polypropylene has been made by incorporating short fibers in as-polymerized, polypropylene having a MFR of up to 20 dg/min. Typically the amount of fiber has been 20-30% by weight of the total composition. A few have been made with 40% fiber content. As the amount of fiber reinforcement in this polypropylene is increased, the degree of warpage increases since the addition of the fiber leads to a decrease in the MFR, thereby making it necessary to increase the temperature and pressure used during the preparation of the fiber-reinforced product. This increased stress in the preparation process leads to the warpage problems. Hence, it is not surprising that heretofore fiber-reinforced polypropylenes with a 40% fiber content have been particularly difficult to mold.
Fiber mat-reinforced polypropylenes wherein the polypropylene is an as-polymerized typical MFR polypropylene and wherein a glass fiber mat is used as the fiber-reinforcing agent also are known. Such products are typically prepared by compression molding the glass mat with the polypropylene. However, these fiber-reinforced products cannot be used in injection molding processes since the glass mat does not flow.
Since the molecular weight distribution of the polypropylene of commerce having a MFR of up to 20 dg/min cannot be readily controlled in the reactor, and since the as-polymerized polypropylene produced cannot be spun into a fiber successfully in all fiber manufacturing processes, methods of visbreaking the polymer were developed to narrow the molecular weight distribution of the as-polymerized polypropylene and to increase its MFR. The most common method used today is to treat these as-polymerized polypropylenes of commerce with a free radical initiator, such as a peroxide, thereby initiating a free radical reaction. The narrower molecular weight distribution and higher MFR are a result of chain scissioning during the free radical reaction. The more chain scissioning which occurs under the particular reaction conditions, the narrower the molecular weight distribution and the higher the MFR of the resultant polypropylene. Polypropylenes having, as a result of visbreaking, a narrow molecular weight distribution, i.e., a polydispersity typically of about 2 to 3, and a high MFR, i.e., up to about 1000 dg/min, are known.
Unfortunately, the visbreaking process adversely affects the physical properties of the as-polymerized polypropylene starting material. This adverse effect increases as the extent of visbreaking is increased. Thus, the higher the MFR of a visbroken polypropylene, the more diminished are its physical properties so that it is generally weaker and less stiff than the as-polymerized polypropylene from which it has been prepared.
Visbroken polypropylene having a MFR of 50 dg/min or more is not practical for use in the preparation of fiber-reinforced polypropylene since it is tedious and difficult to take the polymer through the visbreaking operation as well as subsequent stranding and pelletizing operations which are required before the visbroken material can be compounded with fibers.

High-melt-flow fiber-reinforced propylene polymer compositions


A turbine airfoil includes opposite pressure and suction sidewalls, and extends in chord between opposite leading and trailing edges and in span from a root to an outer tip cap. The tip cap bridges the sidewalls, and a flute extends chordally along the pressure sidewall and below the tip cap.

The present invention relates generally to gas turbine engines, and, more specifically, to turbine blade cooling.
In a gas turbine engine air is pressurized in a compressor and mixed with fuel in a combustor for generating hot combustion gases. Energy is extracted from the gases in several turbine stages which power the compressor and produce useful work such as powering an upstream fan in a turbofan aircraft engine application.
Each turbine stage includes a stationary turbine nozzle which directs the combustion gases through a corresponding row of turbine rotor blades extending radially outwardly from a supporting rotor disk.
The stator vanes and rotor blades include hollow airfoils with internal cooling circuits therein which use air bled from the compressor for cooling thereof during operation. Each stage of vanes and blades is configured differently for maximizing energy extraction from the combustion gases as they flow downstream through the turbine during operation. Each vane and blade also includes different cooling configurations specifically tailored to different heat loads from the combustion gases as they flow downstream over the pressure and suction sides thereof.
The typical turbine blade includes an airfoil having a radially outer tip spaced closely adjacent to a surrounding turbine shroud forming a small clearance or gap therebetween. During operation, the combustion gases flow over the pressure and suction sides of the turbine blade, and a small portion of the combustion gases leaks past the blade tip through the small tip clearance.
The blade tip is particularly difficult to cool since it is exposed to the hot combustion gases on both the pressure and suction sides of the airfoil between the leading and trailing edges, as well as over the tip itself in the tip-shroud gap.
Since blade tips are subject to occasional tip rubs with the surrounding turbine shroud, the tips typically include short height squealer rib extensions of the pressure and suction sidewalls extending radially outwardly from a tip floor that defines an outwardly open tip cavity. The tip floor defines the outer boundary for the internal cooling circuits of the airfoil, and positions the squealer ribs externally thereof which further increases the difficulty of tip cooling during operation.
Accordingly, turbine blade tips are subject to oxidation over extended use in the engine, and may require corresponding repair during maintenance outages of the engine. Oxidation damage to the blade tip commonly limits the useful life of the blade during operation, as well as decreases turbine efficiency as the blade tips oxidize and wear during operation and correspondingly increase the blade tip clearance.
Two significant improvements in blade tip cooling are found in U.S. Pat. Nos. 5,261,789 and 6,672,829, both assigned to the present assignee. In the earlier patent, a tip shelf is introduced along the pressure side of the turbine blade to offset inwardly the pressure side squealer rib for enhancing tip cooling by shielding the tip with a cooling air film for protection against the radial migration of combustion gases over the tip during operation.
The later patent discloses an inclined pressure side squealer rib at the tip shelf for protecting the cooling air film created thereat for enhancing tip performance.
However, since the blade tips are subject to occasional tip rubbing with the surrounding turbine shroud, the squealer ribs are subject to abrasion wear which affects both efficiency of blade tip performance, and effectiveness of the tip shelf cooling.
Accordingly, it is desired to provide a turbine blade with enhanced tip cooling notwithstanding tip rubs.


A wall cap for an interior wall of a building structure, the building structure comprising at least one exterior wall and at least one interior wall and a gap formed between the at least one interior wall and the at least one exterior wall. The wall cap comprises at least one material for abating an undesirable physical property of the gap.

Buildings having an exterior façade primarily composed of glass typically comprise a non-loading bearing curtain wall which supports the glass. The curtain wall typically comprises an aluminum frame for supporting the glass comprising a series of mullions for anchoring the frame to the building structure and may also provide a place to abut vertical and/or horizontal building partitions (e.g. walls, floors/ceilings). The mullions provide a space between the building partitions and the glass which may result in undesirable sound transmission between partitioned spaces within the building. The mullion material may also contribute to the transmission of undesirable sound.
Conventional methods for minimizing sound transmission include adding mass to the mullion or adding sound absorbing materials to the mullion, such as filling the mullion with insulation. Another method involves attaching a vibration isolation cover to the mullion face. In another example, a partition wall is cantilevered out to meet the glass and the partition wall is sealed with the glass using caulk.
These methods for minimizing sound transmission often require modifications for each building structure and typically do not provide the desired magnitude decrease in sound transmission. Methods such as cantilevering the partition wall out to meet the glass do not allow for differential movement between the building and the curtain wall system, which can result in tearing of the sealing caulk.
The space provided between the building partitions and the glass can also result in undesirable transmission of fire between partitioned spaces within the building. Wall to ceiling and wall to floor joints can be provided with fire-rated materials to provide a fire stop or break to safeguard against the spread of fire within adjacent spaces of a building. However, the systems used to provide fire-rated materials to wall to ceiling and wall to floor joints often do not work with a curtain wall structure and thus the intersection between the building partition and the glass can present a challenge in terms of preventing the spread of fire between adjacent spaces when a curtain wall is in use.

Interior wall cap for use with an exterior wall of a building structure


A system includes a compute circuit that preemptively performs a computation on a data word before receiving an indication of data errors from an error checking and correction (ECC) circuit. The ECC circuit reads the data word from a memory array and performs error detection and error correction on the data word. The compute circuit reads the data word and performs the computation on the data word to generate an output value, without waiting for the ECC circuit to check and correct the data word. In response to error detection in the data word by the ECC circuit, the compute circuit delays outputting the output value until correction of the output value in accordance with the error detection by the ECC circuit.

Computer artificial intelligence (AI) has been built on machine learning, particularly using deep learning techniques. With deep learning, a computing system organized as a neural network computes a statistical likelihood of a match of input data with prior computed data. A neural network refers to a plurality of interconnected processing nodes that enable the analysis of data to compare an input to "trained" data. Trained data refers to computational analysis of properties of known data to develop models to use to compare input data.
Certain deep learning applications, such as those that apply single- or small-batch MLPs (multi-layer-perceptrons), RNNs (recursive neural networks), and LSTMs (long short-term memory—a recursive neural network with feedback), typically perform matrix-vector (MxV) multiplications, where a vector (or a narrow matrix) with weight matrix. Other deep learning application, such as those that apply CNNs (convolution neural networks, such as used for image processing, video processing, or computations or classification of a two-dimensional (2D) image) or large-batch MLPs, are generally mapped to matrix-matrix (MxM) multiplications, where a matrix is multiplied with a weight matrix.
Dot-product operations for both MxV and MxM are performed by using an array of multiply-accumulate (MAC) arithmetic units. MAC operations typically require one of the inputs (e.g., the weight matrix) to be read from on-die memory and another input (e.g., the activation vector) to be broadcasted. Data stored in memory is protected by ECC (error checking and correction) for the detection and correction of errors associated with soft errors or process variations.
Traditionally, the system will read the data from memory and perform ECC detection and correction prior to the compute operation. Such an operation incurs at least a one-cycle latency overhead. When a compute operation is an order of magnitude greater than the cycles spent in the memory read, the additional cycle of ECC decoding delay is tolerable. However, iterative compute operations can involve compute operations that have compute cycle times comparable to the ECC decoding delay, which makes the ECC code significantly increase the compute operation time.
Descriptions of certain details and implementations follow, including non-limiting descriptions of the figures, which may depict some or all examples, and well as other potential implementations.

Safety device and safety procedure in the case of a tipping dump body (2) of a truck (1), in which the dump body (2) through the operation of a control (11) in the driver""s cab (4) of the vehicle (1) and by means of at least one hydraulic or pneumatic lifting cylinder (5) is designed to be moved between a lowered transport position (6) and a raised tipping position (7), and to assume a floating position, in which the lifting cylinder (5) is not pressurized and a holding position in which the lifting cylinder (5) is pressurized and the position of the dump body (2) is locked. The device includes a detector (13) that is designed for detection of the driver""s presence in, or absence from the driver""s cab (4), and that either a presence signal or an absence signal is delivered to the control (11) depending on whether or not the driver is in the driver""s cab. The control (11) is designed, in the event of an absence signal from the detector (13), to assume the holding position.

1. Technical Sphere
The invention relates to a safety device and a safety procedure in the case of a tipping dump body of a truck. The dump body is tipped generally by means of two hydraulic lifting cylinders. The invention is especially intended for use in waist-controlled trucks (articulated haulers), but can advantageously also be adapted to other trucks provided with tipping dump bodies or other types of tipping flatbed.
2. Background
Normally, by operating a control in the driver""s cab of the vehicle, a tipping dump body of the aforementioned type can be made to assume a so-called floating position, in which the lifting cylinders are not pressurized and the dump body is free to turn about its tipping center. The floating position is used partly during transport with the dump body resting, with unpressurized lifting cylinders, against the vehicle chassis frame in order to transmit the line of forces downwards from the dump body to the chassis frame in the most advantageous way possible. This floating position is also partly used when the dump body is loaded in such a way, or is in such a position, that it can be lowered from the raised position to the transport position under its own weight and without the action of the lifting cylinders. Where necessary, however, the driver can also lock the dump body in a so-called holding position in which the lifting cylinders are pressurized by means of valve elements in such a way that the position of the dump body is locked in any desired position.
One problem with conventionally designed trucks of this type is that the dump body is allowed to assume the floating position even when the driver is out of the vehicle driver""s cab and thereby no longer has control over the dump body. In this situation, for example, a strong gust of wind may cause the xe2x80x9cfloatingxe2x80x9d dump body to slowly start to turn about its tipping center and to be lowered, uncontrolled, onto the chassis frame, resulting in material damage.
The aforementioned problem(s) are overcome via the safety arrangement and procedures of the present invention(s). In an exemplary embodiment, the invention takes the form of a safety device in a tipping dump body of a truck in which the dump body, through the operation of a control in the driver""s cab of the vehicle, and by means of at least one preferably hydraulic lifting cylinder, is designed to be moved between a lowered transport position and a raised tipping position. A floating position is also accommodated in which the lifting cylinder is not pressurized, as is a holding position in which the lifting cylinder is pressurized and the position of the dump body is locked. In the example, the device has the characteristics of a detector that is designed for detection of the driver""s presence in, or absence from, the driver""s cab. Via this device, either a presence signal or an absence signal is delivered to a controller depending on whether or not the driver is in the driver""s cab. Preferably, the control is designed, in the event of an absence signal from the detector, to assume the holding position.
The invention also relates to a safety procedure for the operation of a dump body of a truck in which the dump body, through the operation of a control in the driver""s cab, and by means of at least one preferably hydraulic lifting cylinder, is moved between a lowered transport position and a raised tipping position. In this aspect of the invention, the procedure further permits the dump body to assume a floating position, in which the lifting cylinder is not pressurized, and to assume a holding position in which the lifting cylinder is pressurized and the position of the dump body is locked. An exemplary procedure according to this aspect of the invention includes the characteristics of a detector that detects the driver""s presence in, or absence from, the driver""s cab and delivers either a presence signal or an absence signal to the control depending on whether or not the driver is in the driver""s cab. The control is configured to, in the event of an absence signal from the detector, assume the holding position.
In summary, the several aspects of the present invention(s) provide a safety system and method that simply and cost-effectively eliminates, or at least reduces, the risk of uncontrolled lowering of the dump body as a result of the dump body being in the floating position when the driver leaves the driver""s cab.
Other special features and characteristics of the invention are described in more detail below.

An oil-free and talc-free cosmetic powder composition which is useful as a foundation, blush, lipstick, eye shadow or mascara powder and which comprises. a) about 0.00 to 90.00% of one or more coloring agents, PA1 b) about 1.00 to 90.00% of silica, PA1 c) about 1.00 to 90.00% of nylon, PA1 d) about 1.00 to 90.00% of polymethylmethacrylate and PA1 e) about 1.00 to 90.00 of mica,. and wherein each of such a) to e) components is in the form of spherical beads having an average particle size in the range of about 1 to 20 microns.

1. Field of the Invention
The present invention relates to an oil- and talc-free cosmetic powder composition. This loose powder composition provides good adhesion to the skin without the use of oil or talc. The composition is useful as a foundation, blush, lipstick, eye shadow, mascara, or other cosmetic powder.
2. Prior Art
The prior art has disclosed various loose cosmetic powders employing microspheres of silica and/or polymeric materials to give a smooth, silky feel to the cosmetic powder. U.S. Pat. No. 4,837,011 shows spherical silica particles having a particle size of 6-20 microns. U.S. Pat. Nos. 4,246,257 and 4,294,823 show microspheres of polystyrene, polymethylmethacrylate or polyethylene having a particle size of 5-15 microns being used in a cosmetic for greasy or oily skin. However, these patents do not show a cosmetic product free of oil.
The prior art has also shown that these same microspheres of silica or polymeric material can be coated with a polymer (polyethylene), titanium dioxide, or other material. This is shown by published Japanese Patent Application 95395/1985 filed May 7, 1985. However, this published application does not show a cosmetic which is oil-free and talc-free. Another published Japanese Patent Application 81512/1981 discloses porous lipophilic silica having a particle size of 0.5-20 microns being used in a cosmetic powder. This published application also does not show an oil-free cosmetic powder.
It would be desirable if a combination of the spherical powders disclosed above could be used in oil-free and talc-free cosmetic powder. Talc is undesirable since it is drying to the skin. Oil is also undesirable since certain people are allergic to cosmetic oils and others have oily skin and thus would prefer an oil-free cosmetic which can still cling to the skin.
It is therefore an object of the present invention is to provide cosmetic powder compositions which are devoid of oils and talc.
A further object of the present invention is to provide a cosmetic powder composition which can be used for a wide variety of applications.

Oil- and talc-free cosmetic powder composition


A luminescent photonic structure that comprises a luminescent material that when excited by an excitation light having a wavelength within an excitation wavelength spectrum of the luminescent material emits luminescent light having a luminescence wavelength spectrum. The luminescent photonic structure comprises a photonic crystal disposed between two other photonic crystals. The photonic crystal has a photonic lattice period within one of the luminescence wavelength spectrum and the excitation wavelength spectrum. The two other photonic crystals each have a photonic lattice period within the other of the luminescence wavelength spectrum and the excitation wavelength spectrum for reflecting one of excitation light and luminescent light propagating within the photonic crystal.

Signal intensity and signal-to-noise ratio may be generally important considerations for molecular and nanoparticle luminescence technologies, applications of which include but are not limited to chemical sensing, biochemical sensing, disease diagnostics, and environmental monitoring.
Novel photonic structures with new properties may find application in light emitting devices and optoelectronics. For example, while light-emitting diodes (LEDs) and related solid state lighting sources may be preferred over incandescent and fluorescent lighting, it may be difficult to engineer an efficient LED with a wavelength spectrum that is desired for an application. Currently, phosphors are used to convert the single emitting color of an LED to another colour or a mix of colours to produce white light, for example. Phosphors may be inefficient and may offer limited spectral shaping.
Photonic crystals (PhCs) are artificial periodic structures consisting of different dielectric materials where the index of refraction varies on length scales of the wavelength of light. The periodic dielectric contrast induces a forbidden region for electromagnetic waves, namely the photonic bandgap, or stop band for partial bandgap, which provides powerful means to control light.

An anisotropic conductive compound is cured by exposing it to heat while in the presence of an AC magnetic field followed by a static, substantially homogeneous DC magnetic field.

1. Field of the Invention
The present invention relates to an anisotropic conductive compound or material and a method of curing thereof.
2. Description of Related Art
Anisotropic conductive compounds are utilized to form conductive paths between pairs of aligned contacts, such as a contact on an integrated circuit or integrated circuit package and a contact of a printed circuit board. A typical anisotropic conductive compound includes conductive particles suspended in a binder. Such anisotropic conductive compound can be interposed in an uncured state between the integrated circuit or integrated circuit package and the substrate whereafter the anisotropic conductive compound can be cured to form conductive paths between contacts on the integrated circuit or integrated circuit package and the substrate while, at the same time, bonding the integrated circuit or integrated circuit package to the substrate.
Heretofore, anisotropic conductive compounds of the type described above were formed into a film which was interposed between the integrated circuit or integrated package and the substrate whereupon, with the application of pressure between the integrated circuit or integrated circuit package and the substrate in the presence of a curing heat, the conductive paths between aligned contacts of the integrated circuit or integrated circuit package and substrate, and the bonding of the integrated circuit or integrated circuit package to the substrate occurs.
A problem with prior art anisotropic conductive compounds is that they require the use of pressure and curing heat in order to form the conductive paths at the same time the bond is formed between the integrated circuit or integrated circuit package and the substrate. Another problem is that the film form of the prior art anisotropic conductive compounds requires special machinery in order to utilize the film in a production environment. Still, another problem is that the prior art anisotropic conductive compounds cannot effectively be utilized with integrated circuits, integrated circuit packages or substrates having adjacent contacts with edge-to-edge spacings less than about 300 xcexcm.
It is, therefore, an object of the present invention to overcome the above problems and others by providing an improved anisotropic conductive compound and a method of curing thereof. Still other objects will become apparent to those of ordinary skill in the art upon reading and understanding the following detailed description.
Accordingly, I have invented anisotropic conductive material comprising electrically conducting material suspended in a binder. The electrically conducting material includes at least one of (i) nickel coated particles having a coating of noble metal, such as silver or gold, over the nickel coat and (ii) gold or silver coated nickel particles.
The particles having the nickel and gold, or silver coatings included at least two of carbon/graphite spheres, glass spheres and mica particles or flakes. The glass spheres can be solid or hollow. The gold or silver coated nickel particles can have a spherical shape, a flake-like shape or some combination thereof.
Where it is desired to form electrically isolated conductive paths between adjacent aligned pairs of contacts having an edge-to-edge spacing as close as 80 xcexcm, the particles including their coatings can have an average maximum dimension between 10 xcexcm and 25 xcexcm. For adjacent aligned pairs of contacts having a larger edge-to-edge spacing, the use of particles including their coatings having a larger average maximum dimension can be considered.
The binder is formed from the reaction product of a catalyst and a compound that includes an aromatic epoxy resin, a dimer fatty acid diglycidyl ester and an oxirane. The catalyst can include a quaternary cyanyl R-substituted amine. The aromatic epoxy resin can be formed from the reaction product of bisphenol-A and epichlorohydrin.
The binder can further include a UV curable modifier formed from the reaction product of a C1-C20 linear or branched alkyl (meth)acrylate, a (meth)acrylated urethane and a C1-C20 linear or branched hydroxy alkyl ketone. The binder can further include a phenolic resin. The phenolic resin may be a novalac resin formed as the reaction product of formaldehyde and one of phenol, cresol and bisphenol-A.
Alternatively, the binder can be formed from the reaction product of a novalac resin, a catalyst and one of a thermally polymerized aromatic epoxy resin and a phenoxy modified epoxy novalac resin.
The viscosity of the uncured anisotropic conductive material typically decreases with temperature. At 25xc2x0 C., the uncured anisotropic conductive material has a viscosity of at least 20,000 cps, in some cases at least 25,000 cps and in other cases at least 30,000 cps. Further the 25xc2x0 C. viscosity of the uncured anisotropic conductive material is up to 100,000 cps, in some cases up to 75,000 cps, in other cases up to 50,000 cps and in some instances up to 45,000 cps. The 25xc2x0 C. viscosity of the uncured anisotropic conductive material may vary between any of the viscosities recited above. Between 75xc2x0 C. and 150xc2x0 C., the viscosity of the uncured anisotropic conductive material is less than 10,000 cps, in many cases under 5,000 cps, in other cases less than 1,000 cps, in some instances less than 500 cps, in other instances less than 100 cps, and typically less than 50 cps. The viscosity of the anisotropic conductive material is measured utilizing a Brookfield Viscometer, such as Brookfield Viscometer model LVT, with a number 6 spindle at 10 RPM and 25xc2x0 C.
I have also invented a method of forming an electronic assembly. The method includes providing a substrate having a first arrangement of conductive contacts and providing an electronic component having a second arrangement of conductive contacts. An uncured anisotropic conductive material is deposited on the first arrangement of conductive contacts and the electronic component is positioned thereon with each conductive contact of the first arrangement aligned with a corresponding conductive contact of the second arrangement. The anisotropic conductive material is heated to a curing temperature for a curing interval sufficient to cause it to cure to a solid. During heating of the anisotropic conductive material, it is subjected to an AC magnetic field followed by a static, substantially homogeneous DC magnetic field. Each magnetic field has a field vector direction that is substantially parallel with the alignment of each conductive contact of the first arrangement with the corresponding contact of the second arrangement. The DC magnetic field can have a magnetic field strength between 400 and 1,500 gauss. The frequency of the AC magnetic field can be in the ultrasonic frequency range, namely, between about 20 kHz and about 500 kHz. The curing temperature and the curing interval can be between 70xc2x0 C. for about thirty minutes and 150xc2x0 C. for about 5 to 7 minutes.
The method can further include, after the electronic component positioned on the anisotropic conductive material and before the anisotropic conductive materials heated to its curing temperature, applying a UV curable adhesive between the substrate and the electronic component and exposing the UV curable adhesive to UV light to cause the UV curable adhesive to cure.

An improved mutant vaccinia virus providing a pock and plaque size on RK13 cells that is approximately the same as those of the Lister original, having a proliferation potency on YTV cells that is approximately the same as that of the Lister original, and having a neurovirulence, assessed by a recovery of an intrabrain virus, that is lower than that of the Lister original; and a process for the production thereof.

1. Field of the Invention
The present invention relates to an improved mutant vaccinia virus and a process for the production thereof.
2. Description of the Related Art
The vaccinia virus was originally developed as a vaccination virus. Recently, however, vaccinia virus has drawn attention as a vector for a recombinant technique, a gene coding for an antigenic protein of a particular pathogenic virus, i.e., exogenous antigen gene, is introduced into a vaccinia virus gene as a vector for the construction of a recombinant vaccinia virus. According to this technique, the development of a vaccine against viral disease, which has been difficult so far, can be realized. Therefore, the vaccinia virus has become useful as a vector virus for the construction of a recombinant vaccinia virus.
A virus for a vaccine must have both a high proliferation potency and a low toxicity (pathogenic potency?), especially neurovirulence. Therefore, to obtain a recombinant vaccina virus by introducing an exogenous antigen gene into a vector vaccinia virus, the vector vaccinia virus per se. must have the above-mentioned desired properties.
The Lister original (LO) strain of the vaccination virus has a high proliferation potency, but at the same time a ralatively high neurovirulence, which is disadvantageous as the vaccination virus and as the vector for the construction of a recombinant virus as a vaccine. As an improved vaccination virus which does not have this disadvantage, a mutant Lister clone 16 (LC16) has been from the Lister original (LO) strain (Hashisum et al. Vacinia Viruses as Vectors for Vaccine Antigens, Elsevier, 1985, p 87-99).
The above-mentioned LC16 was passaged six times on RK cells and cloned by a plaque method to obtain a mutant LC16m0 strain which provides relatively small and even-size pocks on a chorio-allantoic membrane. The mutant LC16m0 was further passaged three times and recloned to isolate an LC16m8 strain, which exhibits a very small pock size. The LC16m8 is advantageous as a vaccination virus in that it has a low neurovirulence, a low proliferation potency in the brian, a low invasion potency, a low recovery of virus from virus inoculated brain, and provides a good histopathlogical feature of the brain after inoculation of virus. However, the LC16m8 is disadvantageous in that it has a low proliferation potency in the skin and a low in vitro proliferation on Vero cells (Hashizume, Rinsho To Virus, Vol 3, No. 3,225-235, 1975).
The gene structures of the original LO strain and the mutant LC16m8 strain were compared, and it was found that a Hind III D fragment of about 10 kb derived from the LC16m8 carries an Xho I site, although a corresponding fragment derived from the LO does not carries the Hind III site, suggesting that genes related to the proliferation and neurotoxicity of virus are present on the Hind III D fragment (Sugimoto et al., Microbiol. Immunol. Vol 29 (5), 401-428, 1985).
As seen from above, although a vaccinia virus which has a high proliferation potency and high pathogenic properties, and a vaccinia virus which has a low proliferation potency and low pathogenic properties, including neurotoxicity, are known, a vaccinia virus possessing a high proliferation potency with a low pathogenic properties is not known.

Mutant vaccinia virus and process for production thereof


A system and a method for scheduling disk writes for use with an application server, transactional system, or other server. The disk scheduler and method is independent of the underlying operating system and the disk hardware. This allows it to be used without porting to the various settings in which application server might be deployed. In some embodiments, a high-performance, transactional filestore is also provided to minimize the latency of small, synchronous writes to disk. The implementation uses a log-structured file system combined with disk scheduling. By relaxing the requirement that log records be physically contiguous, every modification to the disk can be scheduled.

Application servers provide an infrastructure for building distributed transaction processing applications, such as transactional applications, databases, messaging systems (including the Java Messaging System, JMS), conversation state systems, and web services. In a typical multi-tier architecture, such as that described in "Distributed computing with BEA WebLogic server", by D. Jacobs, in Proceedings Conference on Innovative Data Systems Research, Asilomar, Calif., 2003, incorporated herein by reference, clients submit requests to a cluster of application servers which act as a front-end to a collection of databases. In most instances, transactional data is maintained in the databases and is accessed from the application servers as requests arrive. However, this arrangement is less than ideal for data such as messages and business workflow state which are used only by the application servers rather than being shared with other enterprise applications; data which is relatively transient in that it is processed by the application servers and then discarded; or data which is accessed in limited ways, for example, by key or through a sequential scan, rather than through arbitrary queries.
Performance and scalability of the system can be dramatically increased by distributing such data across transactional file stores, each of which is bound to an instance of the application server in the cluster. This architecture moves the data closer to where it will be processed, eliminates contention for the data, and permits optimizations around the specific access patterns. Moreover, tight integration of the filestore with the application server simplifies management and administration of the overall system. Specialized file-based message stores are common for all of these reasons, and can be generalized to include other kinds of data. In particular, placing business workflow state in the same store as its associated messages eliminates the need for two-phase commit between the messaging system and databases.
A factor that must be considered with such systems is that transactional applications, such as databases and messaging systems, make extensive use of synchronous writes. In this process, data is transferred to the physical disk medium before the caller is notified of the completion of the operation. Synchronous writes present a significant obstacle to system performance because, unlike other disk operations, their cost cannot be reduced by caching. The cost of a synchronous write is generally dominated by the time it takes to position the disk head, especially in the case of the small writes that are common in transactional applications. This rotational latency means that transactional writes to disk are a potential bottleneck to system performance.
Disk schedulers attempt to reduce the cost of transaction applications and synchronous writes by selecting blocks that are about to rotate under the disk head. Traditional disk schedulers are implemented at a low-level, in a device driver or disk firmware, and schedule writes to the entire disk on behalf of the operating system. They generally rely on information about drive geometry that is obtained in platform-specific ways. However, one of the problems with the traditional approach to providing file stores and disk schedulers are that they are inherently platform-specific. If the application server is to be used in a different hardware environment or in a different usage setting then it must be ported to that platform or setting. This is prohibitive in terms of development and maintenance costs. What is needed therefore, is a platform-independent means of providing a file store or disk scheduler. Such platform independence would allow an application server to be optimally used in different hardware and usage settings without the need for expensive development, porting. and maintenance costs.

A secure computation device obtains concealed information {M(i0, . . . , iS−1)} of a table M(i0, . . . , iS−1) having one-variable function values as its members. It is to be noted that M(ib, 0, . . . , ib, S−1) generated by substituting counter values ib, 0, . . . , ib, S−1 into the table M(i0, . . . , iS−1) represents a matrix Mb, γ, μ, which is any one of Mb, 2, 1, . . . , Mb, 3, 2. The secure computation device obtains concealed information {Mb, γ, μ} by secure computation using concealed information {ib, 0}, . . . , {ib, S−1} and the concealed information {M(i0, . . . , iS−1)}, and obtains concealed information {Mb, Γ, MU} of a matrix Mb, Γ, MU, which is obtained by execution of a remaining process including those processes among a process Pj, 1, a process Pj, 2, a process Pj, 3, and a process Pj, 4, that are performed subsequent to a process Pγ, μ.

One of symmetric key cryptosystems is Advanced Encryption Standard (AES) (see Non-patent Literature 1, for instance) In the AES, encryption is carried out through round processing that repeats permutation of members, cyclic shifting of rows, linear summation of columns, and addition of round keys. A CTR mode is one of block cipher modes of operation that encrypt plaintext in units of blocks of a predetermined length. When the AES is implemented in the CTR mode, round processing takes place in each block and the resulting cipher text of a key of the block is added to the plaintext of that block.

Embodiments of the present disclosure provide a method and apparatus for outputting analysis abnormality information in a spoken language understanding. The method includes: acquiring first spoken language information and a first analysis result for the first spoken language information; determining whether the first analysis result includes intent information; determining whether the first spoken language information includes a predefined word slot value, in response to determining the first analysis result not including the intent information; and outputting information indicating an existence of an abnormality in the first analysis result, in response to determining the first spoken language information including the predefined word slot value.

With the development of artificial intelligence technology, a smart device (e.g., a smart phone and a smart stereo) is increasingly used by a wide range of users. A user may interact with the smart device via speech, such that the smart device may respond according to the speech made by the user. The smart device mainly analyzes the information inputted by the user through a Spoken Language Understanding (SLU) module, to facilitate subsequent processing for a business logic. However, in practical application, an analysis abnormal situation may occur in the SLU module. If the analysis abnormal situation can be mined out, the analysis effect of the SLU may be optimized with pertinence, thereby improving the user experience of a spoken dialogue system.

A stripe painting apparatus is attachable to square opening hitch receivers mounted on the rear of a pickup truck or other vehicle. The apparatus includes a transverse tubular sleeve in which a boom may be slidably locked to extend outwardly to the left or right. A forwardly extending carriage with a wheeled front end pivots on the boom and carries paint spray heads and applicators for distributing reflective beads onto the wet paint. The carriage pivots between a lower operating position and a locked upright position for highway transport. A pair of crankable jacks with elongate feet mounted on the jack legs are cranked down for ground support during mounting and removal of the apparatus from the vehicle, and for storage of the apparatus. A line guide mounts at any location of a steel vehicle body, enabling one-person operation of the apparatus from the driver's seat using a remote control box.

This invention relates generally to painting apparatus. More particularly, this invention pertains to apparatus for painting stripes on surfaces for traffic control.
Stripes are applied to roadways, parking lots, warehouse floors and the like for directing the movement and placement of vehicles. Durable paints are sprinkled with small reflecting beads to ensure long term night-time visibility of the lines with vehicle headlights.
Prior art painting systems used to apply marking lines to longer lengths of highway generally use large vehicles dedicated to a single use. Because of their large size, lack of maneuverability, high labor consumption and expense, these machines are generally inappropriate for use on smaller projects such as parking lots, building floors, short sections of roadway repair and the like. Such applications generally require enhanced maneuverability because of short lines, line discontinuity, comers and the presence of obstacles to be avoided.
Prior art systems installed in a truck bed and/or on a truck chassis typically require extensive modifications to the vehicle, and may include means for powering the painting apparatus from the vehicle engine. Use of such machines typically requires one or two riding operators in addition to the vehicle driver. Such vehicles are dedicated to the single purpose of line striping.
In these vehicle mounted units, mounting and dismounting of the paint striping apparatus is generally a long and arduous process.
Trailer mounted line markers are difficult to maneuver in cramped spaces. In addition, it is very difficult to obtain straight lines with trailer mounted units because the articulation produces a cyclic lateral motion resulting in a wavy line.
In view of the prior art, the need exists for a surface line marker which may be quickly and easily mounted on a pickup truck or other utility vehicle. Furthermore, a line marking system is needed which may be quickly converted frown an operating configuration to a transport configuration for driving at highway speeds. Such an apparatus which permits the vehicle to be used for other purposes merely by quick, simple removal of the spray system is very desirable, reducing the need for multiple vehicles.

Apparatus for forming an image, comprising a storage for storing a digitized image and a receiver. The receiver includes a matrix, a thermomeltable material disposed in the matrix having a transition temperature range which is above room temperature wherein the viscosity of the thermomeltable material decreases substantially from below to above the transition temperature range, and field-driven particles immersed in the thermomeltable material, so that the particles change optical densities in response to an applied electric field when the thermomeltable material is above the transition temperature range and is stable at temperatures below the transition temperature range. An array of electrodes selectively applies electric fields at an image forming position on the receiver. The apparatus heats the receiver to control the temperature of the receiver to control the response of the field-driven particles in the receiver. Electronic control circuitry coupled to the heater controls the temperature of the receiver when an electric field is applied and coupled to the electrode array for selectively applying voltages to the electrode array so that electric fields are applied at the image forming position at particular locations on the receiver corresponding to pixels in response to the stored image whereby the electrodes produces an image in the receiver corresponding to the stored image.

There are several types of field-driven particles in the field of non-emissive displays. One class uses the so-called electrophoretic particle that is based on the principle of movement of charged colloidal particles in an electric field. In an electrophoretic display, the charged particles containing different reflective optical densities can be moved by an electric field to or away from the viewing side of the display, which produces a contrast in the optical density. Another class of field-driven particles are particles carrying an electric dipole. Each pole of the particle is associated with a different optical densities (bi-chromatic). The electric dipole can be aligned by a pair of electrodes in two directions, which orient each of the two polar surfaces to the viewing direction. The different optical densities on the two halves of the particles thus produces a contrast in the optical densities.
To produce a high quality image it is essential to form a plurality of image pixels by varying the electric field on a pixel wise basis. The electric fields can be produced by a plurality pairs of electrodes embodied in the receiver as disclosed in U.S. Pat. No. 3,612,758. A shortcoming is that this solution requires the incorporation of electrodes in the receiver, increasing the receiver complexity.
One difficulty in above described non-emissive display is in displaying color images. The field-driven particles of different colors can be provided in discrete color pixels. This approach requires the colored particles to be placed accurately. Moreover, the electrodes that drive the colored particles also need to in precise registration to the color pixels when different color image planes are formed. This approach is therefore complex and expensive.
The field-driven particles of different colors can also be stacked in layers. But since the field-driven particles are usually opaque and scatter light, the color layers under the top color layer normally receives less input light and reflect less corresponding colored light back to the viewers. The lower color layers therefore have low color reflection densities.
An additional problem in the receivers comprising field-driven particles is forming images which are stable. Typically the images on these receivers must be periodically reformed to keep the image from degrading.

A cryogenic process system wherein a solids removal filter positioned in a conduit upstream of process equipment is within a filter housing having an angled bonnet which extends to the outside of insulated housing.

In a cryogenic process system, cryogenic fluids, which may be in liquid, gaseous or mixed phase, i.e. gaseous and liquid, form are passed through conduit means to and from process equipment. Owing to the cold temperatures at which the cryogenic process system operates which are below 233K and can be below 150K or even lower, the conduit through which the cryogenic fluid passes is within an insulated housing. Particulate or other solid matter may be in the cryogenic fluid as it passes through the conduit and, because of this contingency, filters are used on the conduit upstream of process equipment that is sensitive to plugging. Over time such filters require cleaning or replacement necessitating entry into the insulated housing which is costly and may also be dangerous.
