2. Description of the Related Art
Due to the high cost of semiconductors, circuit boards and systems it is desirable to provide for a method to be able to remove a semiconductor module from an assembled circuit board without damaging the board or module and thereby enable field replacement capability. At present, such capability is problematic for organic packages, since the actuation loads required in currently available removable solutions exert forces which are incompatible with the organic module structures.
Existing industry solutions for removable packaging interconnect schemes, such as Land Grid Array (LGA) assemblies, apply substantial stresses to the module being connected. Today's best organic module interconnect solution is the use of Ball Grid Array (BGA) solder connections or solderable leads to make the interconnect. Soldered interconnection schemes are not readily replaceable and factory rework processes are difficult and may impact the reliability of the assembled module, particularly in a Pb-free soldering environment. Pin Grid Array interconnects or BGA sockets do provide for more convenient module replacement but can be expensive and often impart changes to electrical parameters, such as increased inductance, that negatively impact device performance. Moreover, these solutions may not be compatible with 1 mm grid I/O pitch.
The best electrical and manufacturing solution available today is the use of Land-Grid Array (LGA) structures. The LGA provides for an array of electrical contact pads on the bottom of the module which is brought into contact with a second level socket to make electrical connections to the circuit board. The drawback here is, in order to establish reliable connections between the module and circuit board, a substantial force (roughly proportional to the number of module pads) must be applied to the interposer/module assembly. Moreover, this actuation force must be maintained for the functional life of the product. The required actuation force is typically excessive for organic semiconductor packages. The high stresses imposed on the laminate substrate structures can cause reliability concerns associated with resin cracks, warpage, inner plane separation and PTH fractures. It is desirable to alleviate the excessive actuation loads associated with a removable interconnect while maintaining manufacturability, electrical performance, reliability, field reworkability, and reasonable cost.

The present invention relates to an imaging lens used in an optical system of an image readout apparatus such as facsimile machine or image scanner and, in, particular, to a readout lens for reducing or enlarging images.
2. Description of the Prior Art
For an imaging lens used for reading out an image in a facsimile machine, an image scanner, or the like which is of a type forming an image of an original image onto an image pickup device such as CCD in a reduced or enlarged state, it has been basically required to have a high resolution at the imaging magnification used, a large peripheral light quantity, and a low distortion. Additionally, together with the recent demand for attaining a compact size and a low cost in the optical apparatus as a whole, it has been required to have a compact size and a low manufacturing cost.
As an imaging lens which can respond to such requirements, there has been known, for example, a compact imaging lens of four-sheet configuration disclosed in Japanese Unexamined Patent Publication No. 7-104185.
The four-sheet imaging lens disclosed in the above-mentioned publication can shorten the length of the whole lens system while attaining a favorable quality in the readout image. When used in a line sensor of a copying machine or the like, however, there has been an increasing demand for reading out images with a wider angle due to necessity for attaining a compact size or the like. Thus, readout lenses with a wider field have been required. Further, there has been a demand for attaining a readout lens brighter than that disclosed in the above-mentioned publication.


A circuitry for detecting a fault current or leakage current on the supply line of an electronic circuit includes a current source which is rated for a maximum allowed fault current or leakage current. The current source is fed by an auxiliary voltage source. The potential on the supply line which prevails when the supply voltage is disconnected due to the leakage current is determined and assessed by a potential monitor.

The present invention relates to a circuitry which is used for detecting a fault current on the supply line of an electronic circuit and which is equipped with an auxiliary voltage source and a potential monitor for determining and analyzing the potential prevailing on the supply line during a testing period.
German patent application No. 42 42 177 discloses a circuitry of this type which is used to monitor a large number of valve coils and their associated final stages. For fault current detection, an auxiliary voltage source is connected to the common supply line for the valve coils by way of a high-ohmic resistor, and the potential on the supply line is measured and analyzed. Before this action, the connection of the supply line to the supply source, i.e., the vehicle battery, was interrupted by way of a semiconductor relay. The associated potential monitor is connected by way of a high-ohmic voltage divider. When a shunt circuit or a leakage current from the supply line to the supply source or to ground occurs, the potential on the supply line will vary.
An object of the present invention is to provide a circuitry of this type which has a high degree of accuracy, sensitiveness and reliability in the detection of fault currents, which also includes leakage currents, and, in addition, can be realized with comparatively little effort. A simple and, hence, low-cost measuring apparatus for monitoring the potential on the supply line is deemed sufficient.


A compact, durable, lightweight and long lasting electrical lighting device which is economical to manufacture and able to be releasably attached to various objects, particularly thinly cross-sectioned members, without unduly burdening the object by its being connected thereto, is composed of a plastic cylindrical housing, a first endcap connected to one end of the housing, a light emitting member mounted to the first endcap, one or more batteries located within the housing for powering the light emitting member, a second endcap slidably connected with the other end of the housing so as to be rotatably and axially guided by slots on the surface of the housing adjacent thereto, a spring for biasing the second endcap away from the light emitting member so as to effect an open circuit between the light emitting member and the batteries, electrical leads and contacts for selectively effecting a closed circuit between the batteries and the light emitting member when the second end cap, serving as an electrical switch, is slid axially along the slots toward the light emitting member, and finally, an attachment member for releasably mounting the electrical lighting device to another object, such as a fishing pole.

1. Field of the Invention
The present invention generally relates to self-contained electrical lighting devices and more particularly to a miniature electrical lighting device which is economical and durable while at the same time compact and lightweight so as not to interfere with the normal functioning of an object to which it is attached.
2. Description of the Prior Art
Fishermen who fish in darkness are unable to see the action at the end of their fishing pole. Accordingly, they must carefully use their tactile sense in order to successfully catch striking fish. This situation would be alleviated if an illumination source could be provided at the end of their fishing pole in order to indicate pole flexing in response to a fish striking the bait.
Miniature electric light sources have been well known in the art for a long time. Most simple electric light sources contain four basic components: a housing, a light emitting device mounted with respect to the housing, batteries located within the housing, and a switch mechanism for selectively connecting the light emitting device to the batteries.
There have been attempts in the prior art to provide a compact, lightweight yet durable illumination device that is adaptably structured for being retrofitted onto a thinly cross-sectioned member, particularly fishing poles, but also related structures such as automobile antennas, as follows. U.S. Pat. No. 4,376,349 to Varczower, dated Mar. 15, 1983, discloses an electric light device having a dry cell battery, an electric switch (which may be actuated by the fishing line tension), a small light bulb and a clip for providing mounting to a fishing pole. U.S. Pat. No. 4,479,321 to Welstead, dated Oct. 30, 1984, discloses an electric light device having a light bulb with a transparent cap, a battery, a gravity actuated switch and an open sided groove for providing a snap fit attachment onto a fishing pole. U.S. Pat. No. 4,586,284 to Westwood, III, dated May 6, 1986, discloses a signalling device for connection to a fishing rod which provides sound and light emission in response to fishing line tensioning. U.S. Pat. No. 2,252,395 to Cohen, dated Aug. 12, 1941, discloses an automobile antenna having a light at its distal end, the light being connected with the car battery. U.S. Pat. No. 3,506,956 to Kolm et al, dated Apr. 14, 1970, discloses a sonically activated sound and light emitting automobile finder which is connected with the radio antenna, the light bulb thereof being located adjacent the base and the light therefrom being transmitted by a fiberglass rod. Finally, U.S. Pat. No. 4,603,333 to Carlson, dated Jul. 29, 1986, discloses a telescoping boat antenna having a light bulb located at the antenna tip.
While the forgoing devices all attempt to provide a practical electrical illumination device suitable for mounting to a thinly cross-sectioned member, none is truly durable, lightweight, compact and long lasting. Accordingly, other attempts in the prior art at providing a practical illuminator of thinly cross-sectioned members have been directed away from electrical systems to chemical systems, as exemplified by the following. U.S. Pat. No. 4,505,063 to Price et al., dated Mar. 19, 1985, discloses a housing which contains two chemiluminescent liquids which react together to emit light, the housing is connected with a fishing pole. And finally, U.S. Pat. No. 4,823,496 to Powell, dated Apr. 25, 1989, discloses a luminous clip resiliently connectable to the end eyelet of a fishing pole.
Thus, despite the need for a compact, lightweight, durable and long lasting miniature electric light device, there yet remains in the art no viable structure of this type. Consequently, what is needed is a miniature electrical lighting device which is compact, durable, lightweight and has long lasting illumination, and which is easily attachable to other objects, particularly thinly cross-sectioned members such as fishing poles, and yet is of simple design so as to be economical to manufacture.


A mobile communication terminal includes timer for detecting the time of an incoming call, a caller number registration table for storing caller numbers, answer message ID numbers and time-dependent switching codes in relation to each other, the time-dependent control codes designating callers for whom answer messages are switched depending on a time zone in which the call is made. There is thus provided a capability of selecting an answer message for a caller based on the caller number included in the incoming call signal and switching between answer messages based on the time of call incoming detected by the timer.

1. Field of the Invention
The present invention generally relates to portable telephone terminals and, more particularly, to a portable telephone terminal having an answering function for switching between answer messages in accordance with a caller number and the time, and also to a terminal operable by a remote telephone set using caller number authentication.
2. Description of the Related Art
Japanese Laid-Open Patent Application No. 10-66145 discloses a mobile communication terminal having an answering function for switching between answer messages depending on a caller number. A call signal incoming at a called terminal from a calling terminal includes a caller number and control information for controlling the called terminal. The called terminal controls an answering mode and switches between answer messages based on the caller number and the control information. Answer messages for individual expected callers are registered in the called terminal and retrieved according to the flowchart of FIG. 7. Each answer message has associated therewith a message identification number.
Referring to FIG. 7, when it is determined in step ST1001 that there is an incoming call, a determination is made in step ST1002 as to whether the automatic answering mode is activated. When the answering mode is activated, a determination is made in step ST1003 as to whether a calling number is identified. If the calling number is identified, a determination is then made in step ST1005 as to whether the calling number is registered in a directory. If the calling number is registered, a determination is made in step ST1006 as to whether the forced answering mode is on. If it is determined that the forced answering mode is turned on, a determination is made in step ST1007 as to whether a predetermined answer message is to be used to automatically respond to the particular caller. If an affirmative answer is yielded in step ST1007, the answer message for that caller is used for response in step ST1008. If a negative answer is yielded in steps ST1003, ST1005, ST1006 and ST1007, a default answer message is used for response to that caller in step ST1004.
If it is determined in step ST1002 that the answering mode is not activated, similar steps (ST1011, ST1012 and ST1009) are executed. When it is determined in step ST1009 that the forced answering mode is not turned on, a normal voice call proceeds in step ST1010.
Japanese Laid-Open Patent Application No. 10-126495 and Japanese Laid-Open Patent Application No. 9-182158 disclose a portable telephone set provided with a capability whereby the portable telephone set, if lost, can be remotely operated by another telephone set so that a dialing operation using the lost portable telephone set is prohibited. Japanese Laid-Open Patent Application No. 10-126495 also discloses a portable telephone set configurable, if lost, for a fixed call destination by feeding a remote operation signal to the lost portable telephone set. Operations related to the memory are prohibited so that the leak of personal information and the illegal use of the portable telephone set are prevented. Japanese Laid-Open Patent Application No. 9-182158 discloses a system wherein a lock preventing an illegal use of a lost portable telephone set is registered in a base station using another telephone set so that call origination by an illegal user is prevented.
A rapidly increasing number of portable telephone sets is being used because of the convenience it provides in enabling communication not bounded by time and place constraints. When a user is not able to answer a call, the answering function is utilized. The related-art mobile communication terminal disclosed in Japanese Laid-Open Patent Application No. 10-66145 is provided with an answering function for switching between answer messages depending on the caller number. However, related-art mobile communication terminals are not capable of switching between answer messages for a particular caller in accordance with the time that a call is received.
A user of a portable telephone set may want to answer a call from a particular caller but does not want to answer a call from the others. The answering function that meets such a requirement should be provided with a forced alert function for alerting a user of a call from a registered caller even when the answering mode is activated.
Another problem with the portable telephone system according to the related art is that an input of a password is required when a user calls a lost portable telephone set and remotely sets up a locked dialing option in the lost telephone set. When the user has forgotten the password, the locked dialing option cannot be set up when necessary.
Accordingly, an object of the present invention is to provide a portable telephone set in which the aforementioned problems are eliminated.
Another and more specific object of the present invention is to provide a mobile communication terminal such as a portable telephone set provided with an answering function that enables switching between answer messages in accordance with the time of calling.
Still another object of the present invention is to provide a portable telephone set in which a remote operation not requiring an input of a password is enabled by specifying terminal numbers (caller numbers) authorized to perform a remote operation for a locked dialing option or a voice mail option.
The aforementioned objects can be achieved by a mobile communication terminal comprising: timer means for detecting the time when a call incoming signal including a caller number is received from an originating terminal; caller number storage means for storing control codes in relation to expected caller numbers, the control codes being used to switch between different modes of operation of the mobile communication terminal; answer message storage means for storing messages to be returned to a caller; and answer message selecting means referring to said caller number storage means so as to determine whether the caller number included in the incoming call signal is registered in said caller number storage means, reading from said caller number storage means the control code associated with the caller number, and selecting an answer message stored in said answer message storage means based on the caller number, the control code and the time of call detected by said timer means.
The caller number storage means may store caller numbers, caller names corresponding to the caller numbers and time-dependent switching codes in relation to each other, the time-dependent control codes designating callers for whom answer messages are switched depending on a time zone in which the call is made.
The caller number storage means may store caller numbers, caller names corresponding to the caller numbers and forced alert codes in relation to each other, the forced alert code designating callers triggering a forced alert option for alerting a user of the mobile communication terminal of an incoming call even when an answering mode is activated.
The caller number storage means may store caller numbers, caller names corresponding to the caller numbers and locked dialing codes in relation to each other, the locked dialing codes designating callers authorized to set up a locked dialing option in the mobile communication terminal from a calling terminal.
The caller number storage means may store caller numbers, caller names corresponding to the caller numbers and voice mail codes in relation to each other, the voice mail codes designating callers authorized to set up a voice mail option in the mobile communication terminal from a calling terminal.
According to the invention, mobile communication terminal is provided with an answering function capable of selecting an answer message in accordance with the caller number included in an incoming call signal and switching between answer messages depending on the time of call. Since it is possible to prepare a variety of answer messages suitable for individual expected callers, the answering function is enhanced.
The mobile communication terminal according to the invention is provided with the capability of alerting the user if a call is received from a designated caller even when the answering mode is activated, by recognizing the caller prior to an off-hook operation based on the caller number included in the incoming call signal. Therefore, it is possible to distinguish between callers requiring an answer and callers not requiring an answer.
In further accordance with the invention, when the caller number matches the registered number assigned a remote operation code, the caller is authorized to perform a remote operation such as setting up of a locked dialing option or a voice mail option. With this, it is possible to perform a remote operation without a password by calling from a registered terminal.

2. Brief Description of the Related Art
Japan Patent. No. 2001-168631 discloses a conventional method for manufacturing a helix antenna providing a frequency of circularly polarized radiation exceeding 200 MHz. As shown in FIG. 1A, a metal (copper) layer 2 is coated (electroplated) on the outer surface of a solid ceramic cylinder 1 in which a central through hole 3 is formed. The metal (copper) layer 2 of the solid ceramic cylinder 1 is etched by a laser etching system (not shown), thereby providing a specific profile as shown in FIG. 1B. As shown in FIG. 1C, a coaxial cable 4 with an exposed copper core 41 is disposed in the central through hole 3 of the solid ceramic cylinder 1. The copper core 41 is then bent and welded to the metal (copper) layer 2 on the top of the solid ceramic cylinder 1, thereby achieving electrical connection between the coaxial cable 4 and the metal (copper) layer 2. At this point, the copper core 41 serves as a feeder. Accordingly, as the solid ceramic cylinder 1 is three-dimensional, the metal (copper) layer 2 cannot be precisely etched to form the specific profile by the laser etching system. Thus, some parameters, such as radio frequency (RF) and impedance matching, of the helix antenna cannot be obtained as required. A test and adjustment device (not shown) must then be applied to fine tune the parameters of the helix antenna.
The following description is directed to the steps of fine tuning the parameters of the helix antenna.
The helix antenna shown in FIG. 1C is connected to the test and adjustment device. Multiple probes of the test and adjustment device are coupled to the helix antenna, detecting magnitude of relative phases and amplitude of electric currents in some specific positions of the helix antenna. According to the detection of the probes, the laser etching system etches the metal (copper) layer 2 on the top of the solid ceramic cylinder 1, forming a plurality of openings 21, as shown in FIG. 1D. Specifically, to fine tune inductance of the helix antenna, the positions, profiles, and sizes of the openings 21 must be carefully arranged, thereby providing the helix antenna with a frequency of circularly polarized radiation exceeding 200 MHz.
A few drawbacks, however, exist in the process of manufacturing the aforementioned helix antenna. Bending and welding the copper core 41 to the metal (copper) layer 2 on the top of the solid ceramic cylinder 1 increases manufacturing time and causes inconvenience. Moreover, the laser etching system is very expensive and laser heads thereof must be replaced after 1500 hours, thereby increasing manufacturing costs of the helix antenna. Additionally, the duration for which the metal (copper) layer 2 is etched by the laser etching system is lengthy. Furthermore, as errors occur during etching of the metal (copper) layer 2 with the specific profile by the laser etching system, the helix antenna must be fine tuned by the test and adjustment device and laser etching system. Namely, the metal (copper) layer 2 on the top of the solid ceramic cylinder 1 is etched and the openings 21 are formed thereon. Accordingly, the process of fine tuning the helix antenna increases manufacturing time and costs thereof.
Hence, there is a need for a helix antenna with reduced manufacturing costs and simplified structure.

The present invention relates to a motor for driving a rotary color filter that is used for projecting and displaying a color picture image and relates to a display unit employing this motor.
2. Description of Related Art
According to a projector in a DLP (Digital Light Processing) system, by rapidly rotating a color wheel having three color filters of R (red), G (green), and B (blue) (hereinafter, abbreviated as "RGB") pasted onto a circular disk, a light emitted from a light source is transmitted through these color filters so that the color lights R, G, and B are sequentially extracted. These extracted color lights are illuminated to a predetermined digital micro mirror device (hereinafter, abbreviated as "DMD") in synchronization with rotation of the color wheel. Then, reflection lights from the DMD are introduced to a predetermined screen and a color picture image is formed and displayed there.
As a conventional motor for rotating a color wheel, one that a shaft to which the color wheel is attached is rotatably supported by a sliding bearing referred to as a sleeve bearing has been known (Japanese Unexamined Pat. App. Pub. No. H05-344675). In this case, the sleeve bearing is made by inserting a shaft in an inner periphery of a sleeve which is impregnated with oil in a cylindrical porous material, and the sleeve bearing serves to support the shaft to be rotated while decreasing friction by forming an oil film between the sleeve bearing and the shaft with oil discharged from the inner periphery of the sleeve.
In the meantime, in the projector in the DLP system, a temperature of inside of a case becomes high due to heat generated from a light source. In recent years, in the projector in the DLP system, an output power of the light source tends to be large in order to improve a picture quality of the projector and a caloric value is also increased. For example, a temperature in the case may be 85° C. and more.
Under such a high temperature environment, a conventional motor for driving a rotary color wheel using the sleeve bearing has a defect that the oil of the sleeve bearing easily vaporizes and the oil is decreased for a short period of time. If the oil is decreased lower than a predetermined amount, the sleeve bearing cannot rotatably support the shaft normally. Therefore, in the conventional motor for rotary driving of a color wheel, an abnormal sound is generated from the sleeve bearing or the picture quality of the projector is deteriorated for a short period of time.
In addition, the conventional motor for driving a rotary color wheel may be attached depending on an arrangement of parts in the case of the projector so that a rotational axis of the motor is attached in the horizontal direction. The motor that is attached in this way cannot be used for a long period of time because the oil of the sleeve bearing easily flows out to the outside due to gravity.


The present invention relates to a method for controlling a loading process of a transport vehicle by a milling device in milling operation, a device for implementing this method and a road milling machine or a device for the removal of soil material with such a device. One aspect of the present invention, according to one embodiment, is a sensor device by means of which the position and partially also the fill level of the transport container of the transport vehicle can be determined.

From the prior art, milling devices are known which comprise a machine-frame-supported milling rotor that is arranged transverse to the working direction. In milling operation, such milling devices traverse overground, with the milling rotor submerging in the ground and milling off the soil material with the help of the milling tools arranged on the rotating milling rotor. In milling operation, the milling device thus moves in the working direction and traverses over the soil to be processed. Typical areas of application of such milling devices include road and pathway construction, for example, in the form of road milling, and the removal of soil material, e.g. in open-cast mining operation. Such milling devices are also preferably designed as self-propelled machines, thus eliminating the need for separate towing vehicles.
An important aspect in the operation of such milling devices is the handling of the milled material, i.e. the material milled by the milling rotor. In many areas of application, it is necessary that the milled material is transported away from the milling location by means of a suitable transport device, for example, a truck. To this end, the milling device usually has a conveyor by means of which the milled material can be transported during the milling operation of the milling device from the area of the milling rotor to the transport container of the transport vehicle. Here, various embodiments are known in regard to the specific arrangement of the conveyor device in relation to the transport vehicle. Apart from the possibility that the conveyor transports the milled material—relative to the working direction of the milling device—to the rear ("rear-loader") or to the side ("side-loader"), a conveyor belt directed to the front ("front-loader") has particularly proven suitable for milling devices designed as road milling machines. The latter has the advantage that during milling operation the transport vehicle may drive in front of the milling device on the ground still to be milled. However, especially this loading type normally places stricter requirements on the milling machine operator. For example, in particular the visibility of the preceding transport trucks is poor and the milling machine operator cannot see the loading trough completely, for instance. The driver of the transport truck cannot see the loading conveyor either. This is especially true when the visibility is also impaired by the local conditions, as is often the case in road construction, for example, due to road curves, narrow roads, traffic flow in the surroundings, ground obstacles, such as manhole covers, etc. In addition, the milling machine operator bears the responsibility for safe work process, particularly with regard to road safety and personal safety. Further, for proper removal of the milled material, precise control of the loading process is desirable. On the one hand, the milled material, which is often milled pavement, has a relatively high density, which can quickly lead to overloading. On the other hand, the transport trucks commonly used here move at speeds of up to 100 km/h, so that the overloaded vehicles may pose a particularly high safety risk.
The fact that the milling device in the working or milling mode is usually in driving operation, that is, it moves along in the working direction, the transport vehicle cannot remain at one place over the entire loading process. It must rather move with the milling device along the working direction in order to remain within the loading range of the conveyor. Since the milling device in milling operation often moves relatively slow, repeated starting and stopping of the transport vehicle has established, which at the same time particularly also allows for uniform loading of the transport container of the transport vehicle. This process will be explained in further detail below, by examples of the operation of a front-loader road milling machine.
In milling operation, for this purpose, a transport vehicle with a transport container travels ahead of the milling device and receives the milled material via the conveyor. The coordination of the moving milling device and the moving transport vehicle is of particular importance here. On the one hand it has to be ensured that the milled material can be dropped from the conveyor into the transport container of the transport vehicle. On the other hand, it is necessary to prevent a collision of the two vehicles during milling and loading operation. Presently, the responsibility for coordination of the relative position of the transport vehicle to the milling device is essentially borne by the operator of the milling device. This operator continuously monitors the distance of the milling vehicle to the transport vehicle and alerts the driver of the transport vehicle continuously by issuing the commands "move forward", "stop", and "depart" for adjusting the position of the transport vehicle relative to the milling device moving in milling operation along the working direction. This usually happens via an alarm signal. Specifically, the milling device moving at essentially constant working speed approaches the transport vehicle up to a minimum distance. The machine operator then issues the "move forward" command, until the transport vehicle has driven forward to the maximum distance for the loading operation and causes the transport vehicle to stop with the command "stop". The maximum distance is the distance between the transport vehicle and the milling device still just allowing the conveyor to discharge the milled material to the rear area of the transport container, without significant amounts of the milled material falling to the ground behind the transport container. The minimum distance is accordingly the distance at which the conveyor is still just able to discharge the milled material to the front area of the transport container or at which the milling device does not collide with the transport vehicle yet, whichever distance is greater. Once the transport container of the transport vehicle has reached its specified fill, which is also monitored by the milling machine operator, the operator indicates completion of the loading process with the "depart" command. Then the loaded transport vehicle departs. This type of loading operation places enormous demands on the operator of the milling device, who, in addition to the milling process (especially observation of the milling edge, operation and control of the machine during the milling process as well as location of the surroundings of the machine), also has to observe the loading process or the relative position between the transport vehicle and the milling device. This leads to considerable stress to the machine operator.

The system in one aspect including a flow loop with a product polymer outlet, the flow loop forming a recycling reactor, a catalyst inlet on the flow loop through which catalyst and solvent flow into the flow loop, a monomer inlet on the flow loop through which monomer and solvent flow into the flow loop and, with the catalyst, form a reactant materials stream, a first heat exchanger on the flow loop for receiving the reactant materials stream and any formed polymer and for removing heat of reaction or polymerization from the flow loop, and pump apparatus for pumping the reactant materials stream and formed polymer in the flow loop and from the first heat exchanger to the product polymer outlet. In one aspect, the system includes at least one additional heat exchanger on the flow loop for receiving the reactant materials stream and formed polymer and for removing heat of reaction or polymerization from the flow loop, the pump apparatus pumping formed polymer and remaining reactant materials to the product polymer outlet, and a portion of the formed polymer and remaining reactant materials flowing out from the product polymer outlet and the remainder recycling through the flow loop. In one aspect systems and methods according to the present invention are used to make polyethylene.

1. Field of the Invention
This invention is directed to an exothermic, controlled flow solution polymerization system and process. In particular, this invention pertains to a non-adiabatic, substantially well-mixed solution polymerization system and process for making ethylene, propylene, and styrene polymers including, but not limited to, polypropylene, styrene block copolymers, ethylene-propylene-diene monomer (EPDM) elastomers, ethylene-propylene (EP) elastomers, ethylene-styrene copolymers, ethylene/alpha-olefin interpolymers, and polyethylene.

Olefin manufacturers have long sought the ability to offer a wide range of product types all produced from a single process platform. With the development and advancement of metallocene catalyst complexes and the continued advancement of traditional Ziegler coordination catalyst systems, the potential has emerged to manufacture diverse olefin polymer types using a single polymerization system. With the recognized polymer product advantages derived from solution polymerization systems (relative to gas phase and slurry or particle-form processes), well-mixed, single- phase solution polymerization has been long perceived as the candidate process to allow full exploitation of various olefin catalyst advancements. However, known solution polymerization systems (i.e., adiabatic stirred tank reactor processes) have important shortcomings that must be resolved before the desired catalyst/polymer product exploitation can be realized. That is, significant process advancements are required beyond adiabatic, stirred reactor solution polymerization. For example, as a primary requirement, the desired solution polymerization system should accommodate or efficiently utilize the wide range of exothermic heats of reaction (heat of polymerization) occurring with respect to various olefin polymer types; for, example, ethylene polymerization being a relatively high heat generator and styrene polymerization being a relatively low heat generator.
Also, to meet accelerating volume potentials for olefin polymers manufactured using various catalyst advancements, particularly advancements pertaining to metallocene catalyst complexes, the desired solution polymerization system should accommodate or utilize the wide range of heats of reaction while maintaining high polymer production rates. Moreover, high productivity should be accomplished without the so-desired solution polymerization system being cost prohibitive to construct or operate, nor excessively large in physical size.
In particular, the desired solution polymerization system should overcome the typical limitations of adiabatic polymerizations wherein polymer concentration and conversion can not be adjusted freely and/or independently. That is, if the heat of reaction or polymerization can be removed from the polymerization system by means external to the polymerization reaction, then polymerization conditions, such as reactor temperature and polymer concentration, could be selectively controlled to selectively optimize polymer production rates, polymer structure, and catalyst efficiencies.
Himont's Spheripol process is well-known in the art of olefin polymerization. Loop polymerization systems are well-known for manufacturing polystyrene.
Meyer discloses in a paper presented at the AIChe Annual Meeting, Los Angeles, Nov. 17-22, 1991, the heat transfer capacities per unit volume for various reactor types. In FIG. 9 of the paper, Meyer discloses that pipe adapted with static mixing devices offers only incrementally improved heat removal relative to empty pipe or a stirred tank reactor. This same figure was also published as FIG. 11 in Chemical Plant & Processing, November 1989, the disclosure of which is incorporated herein by reference. The figure discloses that a static mixer/heat exchanger apparatus comprised of tortuous tubes or conduit pipes is a substantially superior heat exchange apparatus at process volumes greater than 1 cubic meter.
While various polymerization systems and/or reactor types are known for making various products, no known polymerization system or process meets the above stated object. That is, conventional, known loop reactor technology (such as, for example, standard engineering design packages commercially available from Koch which can also include known static mixer/heat exchanger reactors) do not meet the above stated object. For example, while known loop reactor technology can be readily employed for olefin polymerizations characterized by relatively low process side volumetric heat removal requirements, experiments show such technology is ill-suited for olefin polymerizations requiring relatively high heat removal rates.
For olefin polymerizations requiring high heat removal rates, known loop reactor systems are generally restricted to large process volume/size requirements, high recycle ratios and/or low production rates. Also, at least when used for high heat removal/high productivity solution polymerizations, known loop reactor systems are characterized by poor feed/catalyst mixing which results in the occurrence of cold, monomer-rich regions in the reactor system. The occurrence of these regions invariably results in the preparation of polymer product with undesirable polymer fraction, such as, for example, polymer fractions having a higher molecular weight and/or higher density relative to the bulk polymer. Also, these cold, monomer-rich reactor regions can give rise to liquid and/or solid separation (i.e., maldistribution) which in turn results in reactor instability, fouling, and plugging as well as gel formation and product compositional heterogeneity.

A system having a harmonic frequency actuator system is provided including providing an actuator body, the actuator body having more than one set of fingers for generating a motion for a semi-rigid element, and attaching a high frequency actuator to the actuator body forming a harmonic frequency actuator to provide motion at predetermined frequency pairs.

The present invention relates generally to harmonic frequency actuators, and more particularly to a system for a harmonic frequency actuator with dual movements.
Small form factor electronics devices, such as cameras, are becoming common in personal electronics including cell phones and other hand held devices. For small form factor cameras, a motor, such as a DC motor, a stepping motor, an ultrasonic motor, etc., is generally used as a driving source for the focus or focal length adjusting, often referred to as auto focus and zoom, respectively.
Some problems arise by using a motor as a driving source. One problem is that the space required for the motor and a gear reduction block that is necessary for the motor, prevent providing a compact camera. Another problem is that the motor typically has a rising-time characteristic and a multiple-pulse, and as a result a relatively long time interval is needed to move a lens, a film, or an imaging device, to a predetermined distance. Yet another problem is that a dedicated driver circuit for driving the motor is necessary, and thereby costs are increased.
Electronic actuators have been used to address space efficiency, time intervals, and dedicated driver circuit problems. Although well suited for a camera application, actuators fail to address the need of moving two elements to accommodate both zoom and auto focus where two separate lens assemblies need to be moved independently. The industry currently attempts to solve this problem by utilizing two independent actuators. The inherent weakness of two actuators is that twice as much space is consumed in the system. Particularly in the case of cameras intended for use in cell phones, space must be managed carefully.
Numerous technologies have been developed to meet these requirements. Size and power have plagued many of these technologies such as motors and multiple actuators. These technologies have struggled with problems including area, volume and power consumption.
Thus a need still remains for an improved actuator system. In view of the need for more features in less area, it is increasingly critical that answers be found to these problems.
Solutions to these problems have been long sought but prior developments have not taught or suggested any solutions and, thus, solutions to these problems have long eluded those skilled in the art.

A coupling for securing a golf shaft to a golf club head includes a first component configured to contact, and engage with, the golf shaft, and a second component bonded to the first component and configured to space the first component from the golf club head. The second component includes a second material having a Young's modulus less than a first material of the first component. In another aspect, a coupling includes a shaft engagement element, and a spacer configured to space the first component from the golf club head so that the golf shaft is above the golf club head in its entirety. The spacer includes a material having a Young's modulus no greater than about 10 Gpa. In another aspect, a kit includes a first coupling and a second coupling with at least one of a structural configuration or a material of a vibration dampening element differing.

Golf equipment designers traditionally have been interested in improving the "feel" of a golf club head, "feel" being the combination of impact effects between a golf club and a golf ball capable of being sensed by the golfer. The feel of a golf club can include at least in part vibrations emanating through the golf club when contacting the golf ball. These vibrations can be particularly apparent to the golfer when using a putter, which may involve a generally slower and more finely controlled motion than when using other types of golf clubs.
The materials used for a golf club (or club head) or the total weight of a golf club (or club head) may provide a softer or harder feel when striking a golf ball. For this reason, some putters may include an insert material on a striking face of the golf club head that is made of a different material than a remaining portion of the golf club head, or may include a milled striking face to give the putter a softer feel upon impact with a golf ball. Golfers may also add tape, such as a lead tape, to a golf club head to increase the weight of the golf club head and attempt to provide a softer feel when contacting a golf ball. However, such features often fall short of adequately isolating undesirable vibrations resulting from impact and inadequately provide vibration dampening in a manner tailorable to a particular golfer or class of golfer.

Couplings for securing golf shaft to golf club head


A method of operation for a motor vehicle object detection system is described, in which the extent angle of an identified target is accurately determined by applying a point source scatterer identification technique to data at the periphery of a composite return. Return amplitude data from one or more complete scans of the sensor beam are collected and compared with a target threshold to identify objects in the viewing angle, thereby forming an array of amplitude data associated with successive beam positions for each identified object. In each array, the left-most and right-most pair of amplitude data points associated with successive beam positions are selected and individually used to compute the angle of a point source scatterer which would be responsible for that data pair. The computed scatterer angles are taken as the left and right edges of the target and used to determine the angle extent of the identified object, which in turn, enables reliable determination as to whether the identified object is in or out of the vehicle travel path, and what, if any, vehicle response is appropriate to maintain a given headway or avoid a collision with the object.

Motor vehicle object detection systems typically include a high frequency transceiver, a scanning antenna, a signal processor and a vehicle operation system that initiates a warning or evasive vehicle operation. The antenna is designed to project a narrow energy beam, and a scanning device (which may be either mechanical or electronic) scans the beam back and forth through a viewing angle that includes the vehicle travel path angle. The signal processor analyses the amplitude of the beam reflections, or returns, to identify objects in the vehicle travel path. The object detection system may be part of a more comprehensive control system such as a intelligent cruise control system that adjusts the vehicle speed to maintain a given timed headway to the closest in-path vehicle, or a collision avoidance system that warns the driver of an impending collision or initiates an evasive action to avoid a collision. Warnings may be audible or visual, and the vehicle control actions may include braking, engine throttle control, and evasive steering.
Accurate knowledge of the extent, or width, of an identified object is required to determine if the object lies in or out of the vehicle travel path. Accurate assessment of the object extent is often difficult, particularly with large and/or multiple objects which result in a wide angle, composite return. Conventional extent estimation methods based on amplitude thresholds are arbitrary by definition, and generally not sufficiently accurate or reliable.

Angle extent estimation method for a motor vehicle object detection system


A method for adjusting a touch sensitivity of a touch sensor in a portable terminal and an apparatus thereof are provided. The method includes measuring a permittivity of an object located within a preset distance by a grip sensor disposed at a rear portion of the portable terminal when the touch sensor turned-on, and setting and adjusting a touch sensitivity corresponding to the measured permittivity of the object corresponding to the touch sensor of the portable terminal. The method adjusts the touch sensitivity of a touch sensor in a portable terminal according to a peripheral environment to improve the touch sensitivity of the touch sensor.

1. Field of the Invention
The present invention relates to an operating method and apparatus of a portable terminal. More particularly, the present invention relates to a method for adjusting touch sensitivity of a touch sensor in a portable terminal, and an apparatus thereof.
2. Description of the Related Art
In general, a portable terminal has various functions to execute complex functions. In this case, the portable terminal includes an input unit such as a keyboard or a mouse for executing all types of functions, but portability of the input unit is not easy. Accordingly, to solve the foregoing problem, a conventional portable terminal includes a touch panel instead of a keyboard or a mouse. In this case, the touch panel may be composed of a plurality of touch sensors. That is, upon sensing a touch operation in the touch sensor, the portable terminal executes a function corresponding to the touch operation. Here, the touch sensor senses the touch operation according to a set touch sensitivity.
However, in a portable terminal as illustrated above, the touch sensitivity of a touch sensor may change according to a peripheral environment. For example, when a user grips the portable terminal by hand, the touch sensitivity of the touch sensor may maintain. However, when the portable terminal is on a table, touch sensitivity of the touch sensor may be deteriorated. Namely, when the portable terminal contacts an insulated material, the touch sensitivity of the touch sensor may be deteriorated. This may significantly deteriorate the touch sensitivity of a touch sensor in a portable terminal. Furthermore, an operational efficiency of the portable terminal may consequently also be deteriorated.

Method and apparatus for adjusting touch sensitivity of touch sensor in portable terminal


A downhole drilling apparatus suspended by tubing includes a drill bit driven by an electric motor powered by a cable means. The motor is mounted upon a hollow shaft which allows fluid to pass through, so that a fluid circuit along the tube and back along the annulus between the borehole and the tubing via the drill bit is established. The state of the motor, particularly its speed and torque, can be monitored, and the motor may then be regulated as a result of the this data. Various sensors may be included in the drilling apparatus, and the data gathered similarly used to regulate the motor. Thrust means are included to urge the drill along the borehole. Supplementary pumps may be provided to assist the fluid flow. Both the thrust means and the pumps may be controlled by the control means.

Simple CTD services are known using hydraulic motors to provide the rotational torque in the drill bit using hydraulic pressure of a suitable fluid. Whereas initial efforts at CTD were based around remedial work in an existing wellbore, the technology is now used to drill wells from surface and to sidetrack existing wells. Both overbalanced and underbalanced drilling techniques have been evaluated along with advances in directional drilling technology.
However there are significant drawbacks with the existing hydraulic motor systems. They have a very low durability, due mainly to the failure of seals and generally to the problems of transmitting high pressure over long distance in a well. Such failure requires withdrawal of the whole string from the well. Also, conventional coiled tubing drilling techniques have a limited choice of drilling mediums.
It is therefore an objective of the present invention to provide a method of downhole drilling and apparatus therefor which alleviates or overcomes at least some of these disadvantages.

Method of downhole drilling and apparatus therefor


The cable bracket of the present invention generally comprises at least two matingly engageable bracket portions, each having a region for receiving a cable and an arm extending from the distal end of the region. Each arm has a retaining portion and is capable of being moved between a first position and a second position. At the second position, the arms permit the cable to be secured between the retaining portions when the bracket portions are matingly engaged.

Junction boxes have long been used to collect and protect telephone and electrical wires for distribution, splicing, cross connection and other uses. In the telephony arts, such junction boxes are more commonly known as network interface units (NIUs) and/or building entrance protectors (BEPs).
Generally, BEPs consist of a sheet metal or plastic housing with at least one orifice through which an electrical conduit or cable is passed. To prevent the terminated wires from exposure to loads or stresses exerted upon cable, the cable is strain-relieved at the point where it enters the housing wall. Where the cable contains additional wires that are to be terminated elsewhere, the cable is fed through a second orifice to a second housing.
Depending on the design of the building, BEPs may be stacked one above the other or spaced apart over relatively great distances. As such, one problem encountered when laying a cable to and between BEPs is that to position the cable within the BEP housing, the cable must be fed or "pulled" through the BEP orifices. This exercise can be extremely labor-intensive as the weight of the cable must be supported to permit the free end of the cable to be maneuvered through the BEP orifice. Further, when a cable is fed through a BEP orifice, extra care must be taken not to damage the cable insulation as it is pulled through the orifice. As a result, feeding a cable through an orifice increases the amount of time and cost required to properly lay cable.
A second problem encountered when laying cable, is that the diameter of the cable varies depending upon the number of wires required to be terminated at any location. As such, depending on the cable diameter, different methods or products are used to strain-relieve and seal the cable, requiring a significant inventory of various strain relief devices.
It would therefore be advantageous for an apparatus or method to be developed which would alleviate the above-identified shortcomings of the prior art.

Symmetrical cable bracketing and strain relieving mechanism and method


Dispensers, in particular dispensers for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source and dispensers containing dosage counters are described herein.

In general, metered-dose inhalers (MDIs) are devices for dispensing medicaments, e.g. in aerosol form, to the lungs. Broadly speaking dispensers such as MDIs are comprised of two components: a container and a delivery device. The container holds the medication, e.g. dissolved or suspended in a propellant under high pressure to maintain a liquid phase. Additionally the container often comprises an internal metering valve, which is designed to release a precisely measured, reproducible dose of medicament when the valve is actuated. The delivery device typically includes an actuator and a mouthpiece. The actuator, which can be triggered by the user, for example by inhalation or manual operation, typically interacts with the metering valve of the container to induce release of a dose. The mouthpiece serves to direct the medication towards the user.
We have previously described a number of dispensers, see for example U.S. Pat. No. 7,721,731. We have also disclosed dosage counters for use with such dispensers, see for example WO 2010/103315. Further examples of dose counters and dispensers may be found in WO2005/060535, GB2372542 and US2011/259324.
It has been found that, during use of the dispenser and counter, manufacturing tolerances may in some instances affect the performance. As such, we have appreciated the need for an improved dispenser and an improved counter.


A fine powder is reliably dispensed from a hopper into containers on a moving conveyor belt with the assistance of a powder feed system. The hopper serves as a powder inlet that dispenses by gravity into a feed chamber that is form fitted to the sweep of a relatively slow rotating feed wheel with two spaced sets of pins. A relatively fast rotating agitator is located below the feed wheel which has a series of agitating blades that rotate between the span of the feed wheel pins, the blades in at least one embodiment resemble a J-shape. The agitator is located directly above a rotary trap chamber wheel, which has recesses that take doses of powder and dispense them into awaiting containers moving on a conveyor belt below.

Powders are used in a variety of applications, including medical applications. In one example, it has been proposed to deliver certain types of drugs to patients by inhalation of a powder as a delivery mechanism. One particular example uses diketopiperazine microparticles known as TECHNOSPHERE® microparticles. The TECHNOSPHERE microparticles have a platelet surface structure and can be loaded with a drug. One use of these microparticles is the delivery of insulin by inhalation. An inhaler having a replaceable cartridge or capsule containing the drug powder is used for drug delivery.
In the commercialization of drug delivery by inhalation, large numbers of cartridges containing the drug must be produced in an efficient and economical manner. In particular, the cartridges must be filled with precisely controlled quantities of the powder. While TECHNOSPHERE microparticles are highly effective for drug delivery by inhalation, the platelet surface structure causes TECHNOSPHERE powders to be cohesive and somewhat difficult to handle.
One prior art cartridge filling system includes a feed chamber which delivers powder to a dosing wheel. The dosing wheel, in turn, dispenses controlled quantities of powder into cartridges. The prior art system utilizes vibration and a large paddle wheel to facilitate the flow of powder from a hopper through the feed chamber to the dosing wheel. While the prior art system is generally functional, the energy imparted to the Technosphere microparticles causes the powder to compress and performance to be highly variable. The performance of the prior art system depends, at least in part, on the cohesiveness of the powder being handled, which may range from highly cohesive to free flowing.
Accordingly, there is a need for improved powder feeding methods and apparatus.

EP 0 660 492 A1 discloses an electric machine with a rotor shaft that is cooled by transmission oil of a transmission. The transmission has an input gearwheel connected fixedly to the rotor shaft so as to rotate with it. Transmission oil is guided from a gearbox into the rotor shaft as coolant and is returned from the rotor shaft back into the gearbox.
The cooling of the rotor shaft of EP 0 660 492 A1 disadvantageously is dependent on the volumetric flow and on the temperature of the transmission oil and the transmission oil heats up during the passage through the rotor shaft. Furthermore, special seals are needed in the region of the rotor shaft that guides the transmission oil.

Systems and methods for providing secure quantum digital signatures. In one embodiment, a digital signature user creates a plurality of identical “public” keys having one or more bits and a corresponding quantum mechanical one-way function. Quantum digital signature recipients use a “swap test” to check the validity of a copy of the key, and compare the test results with others. The quantum digital signature user sends a signed message over any channel, including an insecure channel. The recipients evaluate the signed message, and quantify the number of incorrect keys. The message is deemed valid and original, or forged and/or tampered with, when the number of incorrect keys is less than a lower threshold, or exceeds an upper threshold, respectively. For an intermediate number of incorrect keys, the recipients determine message authenticity by comparing observations. Hardware useful for application of the method is disclosed.

Digital signatures are useful in commerce that is conducted at a distance. It is A often useful and necessary to communicate one's offer or acceptance of a commercial transaction in writing, using any one of the many forms of electronic communications presently available, such as facsimile (hereinafter "fax"), electronic mail (hereinafter "e-mail"), and documents and/or images in various electronic formats. In particular, it is now the law in the United States that electronic signatures carry the same legal effect as a handwritten signature provided in the "old-fashioned" manner by the use of pen and ink in interstate and international commerce, with certain exceptions (See the Electronic Signatures in Global and National Commerce Act, Public Law 106-229 (2000)). However, the concept of digital signatures is not new, having been proposed in 1976 by Diffie and Hellman.
In the case of traditional handwritten signatures, authentication can be provided by having a signature witnessed, for example by a notary, by the analysis of handwriting samples by experts, and the like. In the case of a digital signature, the problem is to authenticate a "signature" represented by a series of symbols, such as 1's and 0's, transmitted over an insecure communication channel from an unseen source. One major goal of classical cryptography is to certify the origin of a message.
In this document, we shall follow the conventional usage in the literature of quantum computing, in which a first person, called Alice, and a second person, called Bob, are individuals who perform the various manipulations that are discussed. The names Alice and Bob have become customary in such discussions, rather than using arbitrary names or designations.
Classical digital signature schemes can be created out of many one-way functions. ƒ(x) is a one-way function if it is easy to compute ƒ(x) given x, but computing x given ƒ(x) is very difficult. This allows the following digital signature scheme: Alice chooses k0 and k1, and publicly announces ƒ, (0,ƒ(k0)) and (1,ƒ(k1)). Later, to sign a single bit b (where b is 0 or 1), Alice presents (b, kb). The recipient can easily computer ƒ(kb) and check that it agrees with Alice's earlier announcement, and since k0 and k1 were known only to Alice, this certifies that she must have sent the message.
The use of public key digital signature schemes, in which a publicly available key is used to prepare a message and/or signature, and a privately held key is required to decode the message and/or signature, is one approach to providing digital signatures based on a one-way function. The security of all such public key digital signature schemes presently depends on the inability of a forger to solve certain difficult mathematical problems, such as factoring large numbers. The basis for such public key systems is the belief that the problem to be solved involves such great computational difficulty that present computer systems cannot solve the problem in a reasonable period of time. However, improved computer systems, or improved computational methods, can provide the capability to solve such problems in reasonable time periods. In particular, there is no known mathematical proof that such classical systems for the provision of digital signatures are incapable of being defeated by an adversary with sufficient computational power and mathematical capability. For example, with a quantum computer, the solution of certain difficult problems, such as factoring, becomes tractable. With the use of quantum computers, digital signature systems that operate according to classical principles can be defeated, and signatures can be forged. In the terminology of those of skill in the cryptologic arts, the provision of a false signature that is accepted as genuine is referred to as existential forgery.


A smart monitor system includes a hand-held electronic device and a monitor. The hand-held electronic device includes a panel, a control unit, a touch-sensing cover and a wireless communication unit. The touch-sensing cover has a cover and a touch-sensing structure. The cover is disposed on the side of the hand-held electronic device opposite the panel. Partial or total area of the touch-sensing structure is disposed on the cover. The touch-sensing structure is electrically connected to the control unit. The wireless communication unit has a wireless communication chip and an antenna. The wireless communication chip is electrically connected to the control unit, and the antenna is disposed on the touch-sensing cover. The smart monitor system can communicate with and controls the monitor through the hand-held electronic device for various application.

Technical Field
The invention relates to a monitor system and an electronic device, in particular to a smart monitor system and a hand-held electronic device.

With the progress of technologies, various novel information devices are invented, such as cell phones, tablet computers, ultrabooks, or GPS (Global Positioning System) navigation device, etc. In addition to conventional input or control manners by keyboard or mouse, utilizing the touch-control technique to operate the information device is a straight and popular operative manner. The touch display device has a friendly and straight input operative interface, and therefore users of all ages can select or operate the touch display device by fingers.
As to the conventional hand-held electronic device with the touch function, the touch operations are all directly performed on the display panel. However, for the operation on the panel, fingers may shade the user's view or the objects displayed on the display panel, such that the user may erroneously touch and open an undesired link arranged in a high information content density on the display panel by user's finger. Thus, it is inconvenient to operate.
Besides, even if the size of display panel of the hand-held electronic device is enlarged, the enlargement is limited. Its volume is limited to the size which is convenient for users to hold and carry. If the user wants to share the screen displayed by the hand-held electronic device or display it on other monitors, an additional physic cable is required for connection and it is not convenient.
In addition, due to contacting the touch panel to operate the electronic device, it often scratches the panel. Besides, when operating well-known hand-held electronic device with touch function, it usually requires one hand to hold the hand-held electronic device and the other hand to operate on the panel. If the user only uses one hand to hold and operate the device, only the thumb can manipulate the device and thus is it not convenient.
Furthermore, the above-mentioned panel also needs to be configured with the rare earth transparent touch-sensing layer such as ITO (indium tin oxide) so as to be kept in high transparent display performance. But since the rare earth metal indium is unceasingly consumed, the cost of the product is getting higher and higher. Besides, the conductivity of the rare earth metal is worse than that of the normal metal, such that the detection sensitivity for touch is restricted. Therefore, using the rare earth as the transparent touch-sensing layer in the touch display panel is not conducive to the environmental resources and energy conservation. Besides, the transparent touch-sensing layer of ITO in the display panel also reduces the transmittance of the display panel. Even if the ITO is replaced by the metal mesh, the metal interference fringe will be caused to affect the readability of the display panel and therefore the performance and convenience of the manual operation will be reduced.
Therefore, an aspect of the invention is to provide a shadeless touch hand-held electronic device which can prevent the user's view from being shaded by user's finger and reduce the scratch problem. It also provide a smart monitor system which communicates with and controls the monitor through the shadeless touch hand-held electronic device for various application.

An aerial vehicle safety apparatus includes an expandable object and an ejection apparatus. The ejection apparatus includes a container that accommodates the expandable object and has an opening provided on one end side, a moving member provided in the container, the moving member including an emission base carrying the expandable object on a side of the opening, the moving member being movable along an inner wall of the container, and a driver that ejects the expandable object by moving the moving member toward the opening. A space located opposite to the opening when viewed from the emission base and surrounded by the container and the moving member communicates with a space located outside the space through a communication portion.

Various aerial vehicles have conventionally been known. The aerial vehicle includes not only a manned aircraft such as a passenger aircraft or a helicopter but also an unmanned aircraft. In particular, with recent development of an autonomous control technology and a flight control technology, industrial applications of an unmanned aircraft such as a drone have increasingly been expanded.
A drone includes, for example, a plurality of rotors, and flies by rotating the plurality of rotors simultaneously in a balanced manner. At that time, ascent and descent are done by uniformly increasing or decreasing the number of rotations of the plurality of rotors, and movement forward and rearward is done by inclining an airframe by individually increasing or decreasing the number of rotations of each of the plurality of rotors. It is expected that such an unmanned aircraft will more increasingly be used worldwide in the future.
A falling accident of an unmanned aircraft, however, has been feared, which has interfered widespread use of the unmanned aircraft. In order to lower the possibility of such a falling accident, a parachute apparatus for an unmanned aircraft that serves as a safety apparatus has been put into practical use. Such a parachute apparatus for an unmanned aircraft lessens impact at the time of landing by lowering a speed of the unmanned aircraft by using an expanded parachute in the event of falling of the unmanned aircraft.
For example, EP No. 3050805 discloses an aerial vehicle safety apparatus that expands a parachute by operating a piston in a cylinder with thrust force of gunpowders contained in a gas generator and ejecting the parachute through an opening to the outside as a result of operation of the piston.

The second valve assembly includes a body member, a fluid inlet port in the body to receive fluid from the second fluid system, a piston slidable within a body member from the first position closing the inlet port, to a second position opening the closed inlet port in a first spring member normally biasing the piston to the first position.

Flow control devices, such as valves, are widely used for regulating the flow of materials, primarily fluids, from one containerized system to another. A conventional way to supply a fluid material to a containerized system, such as a photoprocessing machine, involves dispensing the fluid material from a receptacle, for example, a flexible container, into a fluid reservoir or distribution channel in the photoprocessing machine. In such applications, the fluids typically are liquid chemicals. The flexible containers or bottles currently used to replenish chemicals in these machines often require that the user first open the container and then pour the contents into the photoprocessing machine. One problem that results during the transfer of the chemicals is leakage. Chemical leakage, of course, exposes the operator to potential harmful effects of the material. Waste of chemicals and associated cost are related problems of the present systems. These shortcomings necessitate a need to supply materials, such as photographic chemicals to photoprocessing machines, and the like, in a containerized system and without leakage. Such systems would then present to the operator as a dripless or dry transfer system.
Consequently, a need has existed in the prior art to provide a dry system for transferring a fluid from a containerized system. Preferably, in such a system, a flow control or valving arrangement would communicate with both fluid systems (e.g. a flexible container for photographic chemicals and the photoprocessing machine) and would be utilized such that when the containerized system is removed, the valving arrangement would close and the user would not be exposed to leakage.
U.S. Pat. No. 5,694,991 discloses a valve assembly that eliminates leakage during fluid transfer between mating the container of mating fluid containerized systems in which the user does not have to open either of the containerized systems prior to transferring of fluid. The valve assembly includes a first member associated with a first fluid system and a second valve member associated with a second fluid system. While this method of assembly provides a system with little or no leakage between the mating systems, a leakage problem may develop when the two fluid systems are brought together for transferring of the fluid. If there exists axial misalignment between the two members, this misalignment can result in potential minor leakage between the two mating parts. Additionally, if either of the members is slightly irregular in shape, this could also add to the potential of small leaks. Further, since one of the members is designed as a permanent installation on an apparatus wherein the member will be subjected to many repeated engagements and disengagements, it is important that the longevity of the permanently mounted mating member be designed such that it withstand repeated use.
In a typical system, one of the containerized systems comprises a container having a liquid such as a photosensitive processing liquid, which is then designed to mate with a fluid system provided in a photographic processing apparatus, for example, a minilab, when liquid is supplied as required. Typically, the processing apparatus will also include a containerized system for storing of the fluid to be transferred. Thus, the valve assembly installed on the minilab will experience many repeated uses while the fluid supply container will be used only once.
Thus, there is a need to provide a valve assembly whereby potential fluid leaks are minimized and is durable so as to allow repeated engagements and disengagements of the valve assemblies.


This specification relates to a power supply control apparatus. In order to solve problems of a power supply control only with respect to a preset time slot and difficulties in power supply to a plurality of consumers and metering of power supplied, which are the drawbacks of the related art electronic power meter, the power supply control apparatus can store or supply power according to a comparison result between a preset reference and a real-time pricing rate. Accordingly, electric charges, which are decided according to an amount of power used and reflect real-time rates thereto, can be saved and an appropriate power supply and an appropriate power reception of a consumer according to the real-time pricing rate can be allowed.

1. Field of the Invention
This specification relates to an apparatus for controlling power supply, and more particularly, an apparatus for controlling power supply, capable of controlling power storage or power supply according to electric charges varied in real time.
2. Background of the Invention
FIG. 1 is a configuration view of a late-night electronic power meter according to the related art.
FIG. 2 is a view illustrating a process of controlling the related art late-night electronic power meter.
As illustrated in FIG. 1, a late-night electronic power meter according to the related art supplies power to many products, such as a heater or boiler, causing a great power consumption, using a late-night time slot, for which a relatively cheap rate is required, taking into account a progressive utility rate. (In this document, power may mean electric power or electricity.) The late-night electronic power meter controls supplied power according to sequential steps as illustrated in FIG. 2. Instead of supplying power directly to a load of a household, the power meter transmits a contact signal to a time switch according to a preset late-night time slot, so as to supply power to the household during the late-night time slot and block (cut off) power supply during the other time slots. The electronic power meter also has a metering function on the time slot basis and a function of inputting, changing and applying a time slot and various settings through data communication with an external communication device.
The late-night power meter according to the related art cannot be applied to real-time pricing because it can turn on a switch only for a preset time slot. Also, one meter enables measurement (metering) only for a load of a single household, which results in a slight limitation of an application range of a system. Specifically, at a place, such as multi-housing, at which a power supply facility is shared, it is disadvantageously impossible to recognize which household consumes what quantity of power supplied. Hence, for reasonable electric charges with respect to each household, the electric power meter has to be installed individually at multiple households. In addition, since power supply and power cutoff are carried out only according to preset time slots, other flexible conditions cannot be handled. Also, an adjustment of the time slot, if desired, is not fast carried out. The late-night electric power meter according to the related art thus has many limitations in use.


A new and distinct Chrysanthemum plant cultivar is disclosed, characterized by having a yellow-colored daisy type flowers that that bloom prolifically. The plant naturally blooms around the last week of August. The plant is free-branching and flexible, with a very round plant shape.

The new cultivar 'ATH THREE YTLG' is a discovered natural mutation of the parent variety 'CGG TNG8' (U.S. Plant Pat. No. 11,740). The new cultivar 'ATH THREE YTLG' was discovered and selected by Lucilene Anatriello in May, 2001, in San Jose Do Rio Preto, State of Sao Paulo, Brazil. The new variety was discovered and selected as a natural mutation which was present on a single branch of the parent variety that was growing in a controlled environment in a plot of approximately 100 plants of the parent variety.
Asexual reproduction of the new cultivar 'ATH THREE YTLG' by terminal cuttings and tissue culture was performed in a controlled environment in Oxnard, Calif. and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.

An adjustment mechanism for a movable platen of an injection molding machine is provided with a push bolt, configured to apply a force to push up the movable platen against a gravitational force, and a pull bolt, configured to apply a force to draw in the movable platen in the direction of gravity. The movable platen is adjusted by regulating its height above a base of the molding machine in a plurality of positions at different distances from a fixed platen.

1 . Field of the Invention
The present invention relates to an adjustment mechanism for a movable platen used in an injection molding machine.
2 . Description of the Related Art
FIG. 1 is a view showing a mold clamping unit of an injection molding machine. The mold clamping unit comprises a movable platen 30, rear platen 31, toggles 32, fixed platen 33, crosshead 34, and ball screw shaft 38. The rear platen 31 and the fixed platen 33 are connected by a plurality of tie-bars 41, and the movable platen 30 can be advanced (to the right in FIG. 1) toward and retracted (to the left in FIG. 1) from the fixed platen 33 by the toggles 32.
A mold 40 is mounted on the movable platen 30. The position of the movable platen 30 can be changed by advancing or retracting the crosshead 34 on the ball screw shaft 38. If the crosshead 34 is advanced (to the right in FIG. 1), in this case, the movable platen 30 is advanced to close the mold.
In precision molding such as lens molding, the parallelism between the fixed and movable platens greatly affects the quality of molded products. The parallelism in the vertical direction is conventionally adjusted by changing the slant or inclination of the movable platen. In general, the inclination of the movable platen is changed by changing the respective heights of the fixed-platen-side end portion of a support portion between the movable platen and the base frame and the opposite end portion. The heights of the two opposite end portions of the support portion are typically changed by a method using wedges, shims, or bolts.
Japanese Patent Application Laid-Open No. 2009-262514 discloses a technique related to an inclination adjustment method for a movable platen using a bolt-and-wedge assembly. Bolts are used as adjustment elements for adjusting the height of the movable platen above a base of a molding machine. The distal ends of the respective threaded portions of the bolts contact the fixed-platen-side end portion of a support block, which is inserted below the movable platen, and the end portion opposite thereto. Thus, the level of the movable platen in the vertical direction above the base of the molding machine in a position corresponding to each of the bolts can be adjusted by means of a wedge-shaped portion of the support block by rotating the bolts.
In the technique disclosed in Japanese Patent Application Laid-Open No. 2009-262514 described above, a front or rear inclination of the movable platen toward a fixed platen can be adjusted by regulating the vertical positions of the movable platen on the fixed-platen side and the opposite side by means of the wedge-shaped portion of the support block by rotating the bolts. Normally, in this case, the movable platen is designed so that its center of gravity is located at an intermediate point between the positions of contact of the bolts, and the degrees to which the positions are raised are adjusted by the weight of the movable platen. If a mold is mounted on the movable platen, however, the position of the center of gravity may be sometimes changed and shifted from between the positions of contact of the bolts. If the bolts are adjusted in this case, the entire movable platen only moves up and down and its inclination cannot be adjusted, in some cases.


Disclosed herein are polyvinyl alcohol products obtained by heat-treating a melt-molded polyvinyl alcohol product composed of a polyvinyl alcohol composition containing 0.01 to 3.0 mmol of a metal compound based on 1 g of polyvinyl alcohol;. a polyvinyl alcohol product obtained by stretching a melt-molded polyvinyl alcohol product composed of a polyvinyl alcohol composition containing 0.01 to 3.0 mmol of a metal compound based on 1 g of polyvinyl alcohol; and PA1 a multi-layer product comprising at least one inner layer of a melt-molded product composed of a polyvinyl alcohol composition containing 0.01 to 3.0 mmol of a metal compound based on 1 g of polyvinyl alcohol.

The present invention relates to a polyvinyl alcohol product and a multi-layer product containing the same.
Polyvinyl alcohol (hereinunder referred to as "PVA"), which is a resin excellent in a chemical resistance and physical properties, especially, in an oxygen gas barrier property in a dry phase, is used in a broad industrial field. PVA, however, has a crystal melting point (hereinunder referred to as "Tm") higher than the decomposition beginning temperature (hereinunder referred to as "Td"). It is, therefore, impossible to utilize a simple melt-extrusion process unlike polyethylene, polyvinyl chloride and polypropylene, and it is necessary to make pellets impregnated with a plasticizer such as glycerin and low-molecular polyethylene glycol or water, and to extrude the pellets by an extruder equipped with special melting, kneading and defoaming mechanisms (see Poval, p.377, published by KOBUNSHI KANKOKAI on Apr. 25, 1984 and Encyclopedia of Polymer Science and Engineering (1989) vol. 17, pp. 186 to 187, published by John Wiley and Sons, Inc.)
Therefore, when PVA is industrially used, it is generally formed into films, sheets and fibers by flow casting or wet spinning after PVA is dissolved in water.
In order to facilitate the hot working of PVA, use as a vinyl alcohol-vinyl acetate copolymer with a view to reducing the saponification degree of PVA or a copolymer of vinyl alcohol and ethylene, etc. has been proposed, but this way is defective in that the oxygen gas barrier property of the product obtained is lowered.
As a composition of PVA and a metal salt, the following methods and products are disclosed in the literatures.
(1) A method of producing a stock solution for a polyvinyl alcohol spinning or extruding product, comprising the steps of: preparing an aqueous solution of 20 to 80 wt % of at least one metal chloride selected from the group consisting of zinc chloride, calcium chloride, aluminum chloride and magnesium chloride or preparing a mixed aqueous solution by mixing not more than 40 wt % of hydrochloric acid, nitric acid or a water-soluble organic compound with the said aqueous solution; and dissolving polyvinyl alcohol or a copolymer mainly composed of vinyl alcohol in the said aqueous solution or mixed aqueous solution (Japanese Patent Publication No. 43-29660 (1968)).
(2) A gas barrier product produced by film-forming a water-soluble high-molecular material with lithium halide added thereto, or impregnating or coating a porous material with a water-soluble high-molecular material with lithium halide added thereto (Japanese Patent Application Laid-Open (KOKAI) No. 49-45882 (1974)).
(3) A method of producing a polyvinyl alcohol polarized film, comprising the steps of: film-forming an aqueous solution of polyvinyl alcohol with a water-soluble metal halide dissolved therein by flowcasting; and uniaxially stretching the film at 90.degree. to 150.degree. C. (Japanese Patent Application Laid-Open (KOKAI) No. 56-25419 (1981)).
(4) A heating element for generating heat by water, produced by mixing 3 to 100 parts by weight of a water-soluble resin with 100 parts by weight of magnesium chloride (Japanese Patent Application Laid-Open (KOKAI) No. 60-120784 (1985)).
(5) A moldable desiccating agent comprising a deliquescent salt and a high-water-absorbing synthetic resin as the main ingredients (Japanese Patent Application Laid-Open (KOKAI) No. 61-141916 (1986)).
(6) An adhesive PVA hydrogel composition comprising polyvinyl alcohol and a divalent metal salt as well as water as the main ingredients (Japanese Patent Application Laid-Open (KOKAI) No. 1-230659 (1989)).
However, conventional compositions of PVA and a metal salt, and products produced therefrom cannot be said to have a sufficiently high gas barrier property and, especially, in an atmosphere of a high humidity, the gas barrier property of such a film is so greatly lowered that the film cannot be put to practical use as a food packaging film.
As a result of studies undertaken by the present inventor so as to solve the above-described problems, it has been found that a PVA product obtained by heat-treating and/or stretching the molded product of PVA with a specific amount of metal compound added thereto and a multi-layer product having at least one inner layer of a melt-molded product of PVA with a specific amount of metal compound added thereto can maintain a high gas barrier property even at a high humidity. On the basis of these findings, the present invention has been achieved.
