Title: Individual data indentification device
Inventor: ARIMOTO TATSUYA
IPC: B42D15/10
Filed: 1990-05-09
Abstract: PURPOSE:To remove noise and to accurately read only characteristic data by providing an identification card which on/off-drives a liquid crystal shutter based on individual data and a card reader which reads individual data of the identification card by means of straight polarized light. CONSTITUTION:When reading polarized light projected from the light-projecting part 103 of the card reader 10 is made incident on the identification card ID 1, polarized light passes through the liquid crystal shutter only when the liquid crystal shutter 4 which is driven based on characteristic data is in an open state, and about half of a polarized light component which is orthogonal to incident polarized light is reflected towards the card reader by a recurrent reflector 5. Only the reflected polarized light is photoelectrically converted in a light reception part 108 through a polarized filter plate 106 where the direction of polarized light is orthogonal to the projected polarized light in the projecting part. Since the polarized direction of other polarized light which is reflected at the periphery of the identification card or the like does not change, it is prevented at the polarized light filter plate on a light-receiving-side and it is prevented from being made incident on the light-receiving part, whereby noise does not occur. Thus, characteristic data by the turning on/off of the liquid crystal shutter can accurately be read.

IPC: H01M8/04
Filed: 1994-05-11
Abstract: PURPOSE:To decrease drop in cell output performance by stopping operation of a fuel cell when the voltage of a unit cell drops to a previously set limit value, and passing a hydrophilic functional group removing gas in a cathode from which an oxidizing agent gas is purged. CONSTITUTION:When cell output performance drops by excessive wetting of a cathode catalyst layer 2b during cell operation and voltage of a unit cell reaches a previously set limit value, cell output performance drop is decided to be caused by excess wetting of the catalyst layer 2 and operation of the cell is stopped for a while. Nitrogen gas is supplied to a cathode 3b to purge an oxygen component of an oxidizing agent remaining in the cathode 3b, then hydrogen gas serving as a hydrophilic functional group removing gas is supplied to conduct hydrogen reduction treatment to the cathode 3b. That is, a hydrophilic functional group produced on the surface of carrier carbon in the catalyst layer 2b is reduced and removed. Or, gas or steam which takes hydrophilic property is brought into contact with the cathode 3b. Wettability of the catalyst layer 2b is decreased, and drop in power generation caused by excessive wetting of the catalyst layer 2b is reduced.

Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a laser processing method and device therefor which enables a stable laser processing, even when a focus point of a condensing lens slips delicately during copying due to up-and-down movements of a gap between the tip of a laser processing head and a work by holding a stable focus point through an adjustment of the slip.

IPC: H04J3/06
Filed: 1990-05-14
Abstract: PURPOSE:To obtain a bit shifting circuit which does not require a high speed element such as ECL by executing a bit shifting operation to low speed parallel data. CONSTITUTION:Data obtained by shifting input data D0-Dm by arbitrary number of bits within (n) bits can be obtained by inputting parallel data D0-Dm of (m) bit to a flip flop group and fetching data from the output of the prescribed flip flop. Then, (m) selectors 21-2m consist of m:1 selectors and (m) inputs are respectively connected to the output of the prescribed flip flops in the flip flop group 1. Respective selectors are switched so that they can select the inputs in the same order in correspondence with a selective signal and an output channel, and they generate outputs (1-m). A multiplexing part 3 obtains serial data obtained by sequentially shifting data by the arbitrary number of bits in correspondence with the selection of the selectors 21-2m by multiplexing the outputs (1-m) of (m) the selectors 21-2m. Thus, the high speed element such as ECL is not required.

Filed: 1992-04-15
Abstract: PURPOSE:To provide the A/D conversion bit expansion circuit relating to a device requiring digital processing by adopting the configuration including especially a comparator circuit, a control circuit and an amplifier circuit for the A/D conversion bit expansion circuit. CONSTITUTION:An analog video signal SV from an analog input terminal 10 is fed to a sample-and-hold circuit 1 and its output SVS is fed to an amplifier circuit 4 and a comparator circuit 2. The circuit 2 compares N-kinds of REF signals set to a REF input terminal group 11 with the output SVS from the circuit 1 and outputs the result as an output SEL. The output SEL is fed to a control circuit 3, from which a control signal Ga in response to the output SEL is generated when the N-kinds of the REF signals have a prescribed relation. Then the signal Ga and the output SVS from the circuit 1 are fed to the amplifier circuit 4, in which the signal is amplified based on the level of the signal Ga. Thus, a small level signal is amplified at a higher gain by the circuits 2, 3, 4 when the level is lower, and the bit is shifted and the number of digital signal bits is expanded.

Inventor: WATABE HITOSHI
IPC: F25B43/00
Filed: 1989-05-15
Abstract: PURPOSE:To cool thermal medium air to be cooled without generating any excessive dehumidification even at a high temperature and a high humidity by a method wherein a low pressure receiver and a first low pressure gas line are connected to each other through a cooling circuit having a first changing-over valve, a refrigerant cooling unit and a second changing- over valve, and then a third changing-over valve is arranged at the low pressure receiver rather than a connecting part with the cooling circuit in the first low pressure gas line. CONSTITUTION:Under a normal operation, a high pressure gas compressed by a compressor 20 is liquefied by a condensor 22, expanded by an expansion valve 26 to make liquid from the gas. The liquid is heat exchanged with thermal medium air to be cooled through an evaporator 28 to make gas from the liquid.

In case that a temperature of the thermal medium air to be cooled is higher than a natural cold heat temperature, the compressor 20 is stopped, the first changing-over valve 53 and the second changing-over valve 35 are opened and then the third changing-over valve 31 and the fourth changing-over valve 25 are closed. The refrigerant circulates through the evaporator 28, a refrigerant cooling unit 34, the low pressure receiver 24, a liquid pump 29 and the evaporator 28. The refrigerant is heat exchanged with the thermal medium air, evaporated, heat exchanged with the surrounding air or well water by the refrigerant cooling unit 34, cooled and condensed. In this case, even if the thermal medium air to be cooled shows a high temperature and a high humidity it is possible to perform a cooling operation without generating any excessive dehumidification.
