Title: Electrode division type liquid crystal light valve
Inventor: IWAKI TADAO
IPC: G02F1/1343
Filed: 1989-06-16
Abstract: PURPOSE:To divide optionally and write information optically by dividing a transparent electrode which is inserted between the transparent substrate and photoconductive layer of the liquid crystal light valve into >=2 parts which can be applied independently with voltages. CONSTITUTION:The liquid crystal light valve is formed of transparent electrode layers 2a and 2b as a voltage applying means inserted and held between transparent substrates 1a and 1b and the photoconductive layer 5, and the layer 2a is divided into >=2 parts which can be applied with the voltages independently. Then the write surface of the light valve is irradiated with a Fourier- transformed image, which is recorded by applying the valve with a DC bias voltage generated by superposing an opposite-polarity DC bias voltage or high- frequency AC voltage which is less than the threshold voltage at dark time and larger than the threshold voltage at light time. Further, a bias voltage is applied to only a specific electrode of the divided electrode 2a to perform writing to only a specific area. Consequently, the information can be divided optionally and written.

Inventor: HATANO KAZUTOSHI
IPC: G09G3/36
Filed: 1989-06-16
Abstract: PURPOSE:To increase a data transfer speed without increasing the latch operation speed of a driving means single body by outputting individual synchronized shift clock pulses to driving means in respective groups. CONSTITUTION:Driving means 2A and 2B of a 1st group and driving means 2C - 2E of a 2nd group begin to latch data at the same time with the same latch pulse(LP) signal. Further, a shift clock pulse(SCP) signal generated by inverting an SCP signal applied to the driving means 2A and 2B of the 1st group by an inverter gate 7 is applied to the driving means 2C - 2E of the 2nd group. Therefore, two transfer cycles are obtained in one cycle of the SCP signal and the amount of data which can be transferred within one horizontal display period can be increased up to twice by using the driving means which have the same data latch operation speed.

Title: Tracking controlling system of optical disk
Inventor: OGAWA KOUICHI
IPC: G11B7/09
Filed: 1981-09-30
Abstract: PURPOSE:To facilitate production of an optical disk, by providing an address information hole of a specific depth and at the same time performing a tracking control with a track shift signal and a sector pulse. CONSTITUTION:The address information of an address information region R4 is expressed by the bits A'1-A'n of 1/4lambda (lambda: wavelength of light beam) depth. The reflected light given from a disk D is made incident to a photodetector K, and the address information signal is fed to a sector separating circuit B. Thus a sector pulse is obtained. At the same time, the output of the detector K is detected S for the track of a spot, and a signal of a level corresponding to a degree of track shift is delivered in a scanning period of the same sector from sample holding circuit H. This output signal is fed to a driving circuit W of a rotary mirror M, and the mirror M is turned by an angle corresponding to the degree of the track shift. Thus a light spot is irradiated on a correct track.

Title: Pulse counting system
Inventor: OZAWA MASAYUKI
IPC: H03K21/00
Filed: 1984-07-26
Abstract: PURPOSE:To obtain the integration value of an action restoration mode through a simple circuit by using a counter which counts the input pulses only when an integration value calculating means is inactive owing to a service interruption, etc. CONSTITUTION:A stop signal ST is kept at 1 in a normal mode, and the pulse input is supplied to a counter 11 via an AND circuit 12 and an OR circuit 13. In such a case, the counter 11 performs no counting action since a control signal P0 is set at 1. When a processor stops its actuation owing to a power failure, etc., the signal P0 is set at 1. Thus the counter 11 starts its counting action. When the power failure is recovered, the processor obtains a complement of the number of input pulses to all the number of times of counting of the counter 11. Thus the count value of the input pulses can be obtained even in a power failure mode. This obtained count value is added with the integrated value obtained before the power failure. Thus, the integration value is calculated. Thus, the integration value of the recovery mode can be obtained through a simple circuit.

Just after the grip part 5 passes through the press roll 17, the press roll 17 is immediately separated from the tension reel 16, and waste coiling of 1.5-2 coils which is coiled onto the tension reel 16 is executed while giving looseness to the steel strip 13.  Thereafter, coiling onto the tension reel 16 is executed while adding tension to the steel strip 13.

Abstract: PURPOSE: To avoid a failed battery surely by providing a working means connected with a switching means to shift a conduction shunt member made of a shape memory alloy, shrinking in response to means for sensing the voltage variation between a pair of contacts in a circuit, from a nonconducting position to a conducting position. CONSTITUTION: When a detector 50 connected between terminals 70, 80 detects an open circuit damage in a battery 20 under a state where the shunt member 40 of a circuit bypass unit 30 is set open, the shunt member 40 is triggered and switched to a close position selectively. An HTR 60 made of an HTR shape memory alloy shifts the shunt member 40 to a conducting position between terminals 70, 80 in response to a voltage detected between them. This arrangement realizes a highly reliable shunt mechanism for avoiding a failed battery.

Abstract: PROBLEM TO BE SOLVED: To inform the reception of a call automatically without requiring man-hours within free of charge by adding a flag denoting it that a call is received in a communication disable state to a position registration reception signal returned from an exchange to a portable set and sending the resulting signal. SOLUTION: When a portable set 40 makes a call to a portable set 43 whose communication is disable at present, the call request from the set 40 is given to a base station 20 via a radio control channel and fed to an exchange 1.
