Title: Liquid crystal light valve and its driving method
Inventor: KAWABATA YUKIO
IPC: G02F1/135
Filed: 1991-02-26
Abstract: PURPOSE:To enable high-speed processing and reduce the deterioration of a liquid crystal layer by synchronizing a voltage applied to the liquid crystal layer and write irradiation light with each other and setting the mean value of the voltage applied to the liquid crystal in one frame period nearly to zero. CONSTITUTION:There are the liquid crystal layer 205 and a photoconductive layer 209 between electrodes 203 and 203'. At this time, the impedance of the photoconductive layer is much larger than that of the liquid crystal layer, so the driving voltage to the liquid crystal layer 205 has a little variance. The photoconductive layer 209, however, is irradiated with the write light 210 and then decreases in impedance at the irradiated part, so that the impedance of the photoconductive layer is much less than that of the liquid crystal layer. For the purpose, the voltage applied to the liquid crystal layer and the write irradiation light are synchronized with each other to minimize variation in the quantity of transmitted light which occurs in the write light irradiation period. Further, the voltage mean value in one frame period can be reduced almost to zero by setting the minimum irradiation time of light irradiating the photoconductive layer 209 to 1/n (n: optional integer) time as large as the minimum pulse width of the voltage applied to the liquid crystal layer 205.

Title: Player for housing plural disks
Inventor: SHIMIZU AKIRA
IPC: G11B23/023
Filed: 1990-02-09
Abstract: PURPOSE:To reduce the projecting surface of a surface required for moving trays by half and to miniaturize a player by alternately dividing plural tray holding members into two groups and shifting surfaces along which the holding members in the respective groups are moved. CONSTITUTION:Six tray holding arms 43-48 in one tray holding arm group arranged at the back of a magazine 5 are arranged while being shifted so as to be alternately rocked along two mutually various surfaces. Namely, the arms 43, 45 and 47 are defined as one small group and remaining arms 44, 46 and 48 are separated as the other small group. Then, the virtual surfaces, along which the arms in these both small groups in to be moved, are mutually shifted on a horizontal surface. Thus, by setting the two virtual surfaces so as to be mutually overlapped horizontally, the projecting areas of the virtual surfaces required for moving the trays are reduced by half and the player can be miniaturized as a whole.

Title: Operation data collecting device for programmable controller
Inventor: YOSHIDA MASAKI
IPC: G05B23/02
Filed: 1992-02-18
Abstract: PURPOSE:To surely collect observed system signals at the time of establishing observation conditions without increasing the capacity of a signal storing means by forcedly collecting the observed system signals regardless of whether the signal storing means is full or not when the conditions are established. CONSTITUTION:An observed system setting means sets the observed system signals out of input signals and control signals. A data collecting area 19c stores the prescribed amount of observed system signals. When the data collecting area 19c is not full, a first writing means writes the observed system signals in the storing means in the order of the lapse of time and when the area 19c is full, no signal is written. When the observation conditions are satisfied, a second writing means writes the observed system signals in the data collecting area 19c regardless of whether the data collecting area 19c is full or not. Thus, the observed system signals can be surely collected when the observation conditions are established.

Title: Paper money incoming/outgoing processor
Inventor: AZUCHI ISAMU
IPC: G07D9/00
Filed: 1988-02-13
Abstract: PURPOSE: To continuously distribute and load returned paper money by feeding a returned paper money to a money reception opening as it is without stopping a cartridge distribution and loading mode even if the paper money is returned owing to a discrimination detect. CONSTITUTION: A paper money storage cartridge has plural cartridges. When cartridge loading is selected and then set as guided on a display part 31 and a start key is pressed, a CPU 39 feeds a paper money out of the cartridge and passes it through a discrimination part and to start a process. If the paper money is returned during the process, the display part 31 requests the extraction of the returned paper money from a money payment slot, the insertion of the returned paper money into a money reception slot, and the depression of the start key. Consequently, the returned paper money is taken in a device main body, and distributed and loaded in the cartridge. During the loading process operation, the CPU 39 stores a RAM 41 with the number of bills which are distributed and loaded and the number of returned paper monies.  Thus, the loading to the cartridge can be carried on without stopping the loading mode even if a paper money is returned.

Title: Magnetic bubble memory element
Inventor: YOSHIOKA SHINYA
IPC: G11C19/08
Filed: 1979-03-19
Abstract: PURPOSE: To obtain the memory element fuaturing a short reading and writing time for the data within the house-keeping loop, by providing the house-keeping loop including the exclusive generator installed independently at the place nearest the detector.  
     CONSTITUTION: Minor loops 32 and 33 are provided at the odd and even sides in 130 pieces each, for example. And house keeping-loop 31 is provided adjacent to the even side. This loop 31 is positioned nearset detector 60 and contains generator 11 exclusive for the house-keeping loop and installed independently. Thus the magnetic bubble generated from generator 11 is transferred along writing line 71 to be written via writing gate 21. Writing line 71 joins writing line 73 connected to minor loop 33, but no disturbance is caused to the bubble rows at the joint point since the exclusive generator is provided independently. As a result, the writing time can be reduced greatly without delaying the reading time.

IPC: G05B21/02
Filed: 1983-02-28
Abstract: PURPOSE:To fix the loop gain of a servo system and to stabilize a servo operation by sampling an error signal with a signal synchronized with the information signal. CONSTITUTION:Input signals (a) and (b) are supplied to an input terminal 22 of a waveform shaping circuit 20 as well as to the negative and positive input terminals of operational amplifiers IC1 and IC2, respectively. Then these signals (a) and (b) are compared with reference voltages Vth(W) and Vth(R). If the input voltage is higher than Vth(W), the outputs of IC1 and IC2 are set at +15V and -15V respectively. The error signal supplied to the terminal 22 is delivered as it is from an output terminal 26 in the form of a sample holding error signal. In such a way, an error signal is sampled with a signal synchronized with an information signal. As a result, the loop gain of a servo system is fixed and the servo operation is more stabilized. In addition, the more accurate and more stable record and reproduction are possible to a recording medium.
