Title: Master slice lsi
Inventor: KOMOTA MICHIO
IPC: H01L21/82
Filed: 1989-10-13
Abstract: PURPOSE:To reduce the electric power consumed by the title LSI when the LSI is actually used by turning on and off a transistor connected with resistive loads in series so as to discontinue the electric current flowing through the resistive loads. CONSTITUTION:This master slice LSI is constituted of resistive loads 6a-6d formed by connecting common-gate p-channel transistors in series, the first p-channel transistor 7 connected with the load 6a in series, the second p-channel transistor 8 connected with a power source 2, and an n-channel transistor 9 connected between the transistor 8 and GND 3. Accordingly, when a low-level input is made, the electric current flowing through the resistive loads can be discontinued and, when an input is high in level or opened, the input is pulled up through the resistive loads. Therefore, it becomes unnecessary to worry about the electric current flowing through the resistive loads and the electric power consumed by this LSI when the LSI is actually used can be reduced.

Title: Balance type pressure reducing valve and water supply device
Inventor: TAKADA TSUTOMU
IPC: G05D16/10
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To easily set the outlet pressure and also to prevent occurrence or a secular charge by detecting the pressure that affects the secondary side of a throttle bush and controlling a switch valve linked to a pressure control chamber based on the detected pressure. SOLUTION: This pressure reducing valve 50a detects the pressure that affects a face A set opposite to a face B partitioning an intermediate chamber 21 of a throttle bush 22, i.e., the pressure generated at the outlet 39 of the valve 50a via a pressure detection part 28 and sends this detected pressure to a control part 20 in an electric signal. The part 20 calculates the detected pressure value and also the pressure value that is set by a setting unit 20A. Based on these calculation results, a switch valve 29 is actuated to supply the water to a drain 40 in response to its opening degree as an electric switch valve that can digitally operate. Thus, it's possible to keep the output value of a pressure control chamber 25 and accordingly to set the outlet pressure of the valve 50a at a level set by the setting unit 20A.  As a result, the outlet pressure of the valve 50a is throttled by the bush 22 and set at the level set by the setting unit 20A.

Title: Recovering method of orientation of ferroelectric liquid crystal layer
Inventor: ONUMA TERUYUKI
IPC: G02F1/1337
Filed: 1986-11-07
Abstract: PURPOSE:To recover orientation of a ferroelectric liquid crystal layer to preserve desired display contrast and response characteristic by heating the ferroelectric liquid crystal layer contg. defect of orientation to convert the layer to an isotropic phase or a cholesteric phase, then cooling slowly. CONSTITUTION:When an electric voltage is impressed repeatedly to an electrode, the orientation of a liquid crystal layer 5 is disturbed by and by, and the contrast ratio (the ratio of light quantity at the stage of opening shutter to that of closing shutter) is reduced. Therefore, when each one end of both common electrodes 2-1 is connected and electric current is passed through the common electrodes, the liquid crystal layer 5 is heated by the heat generated by the electrodes, and the liquid crystal layer 5 becomes isotropic. When, thereafter, the temp. is lowered by reducing the electric current little by little, the liquid crystal phase is converted to chiral smectic C phase via a cholesteric phase and a smectic A phase, and cooled further to room temp. If such reorientation process is executed, the state of orientation of the liquid crystal is recovered to almost the initial stage, and the contrast ratio and the response characteristic are recovered to the original state.

Title: Speed controller
Inventor: HASHIRANO MASARU
IPC: G05D13/62
Filed: 1986-11-10
Abstract: PURPOSE:To detect the error of a frequency generator FG with improved accuracy and to correct the FG error with high accuracy by increasing the clock frequency in the detection mode of the FG error and increasing the rotational frequency of a rotor. CONSTITUTION:A clock selection means 11 has the input of clock pulses fCK1 and fCK2 and by switching these pulses with a write/read signal SRW outputs them. Then the pulse fCK1 is outputted in a read mode of a memory means 10 when fCK1<fCK2 is satisfied. While the pulse fCK2 is outputted in the write mode of the means 10. If the clock frequency is multiplied by N in a detection mode, i.e., in the write mode of the means 10, the rotational frequency of a rotor can be multiplied by N up to f0'. At the same time, the discriminating gain can be set at 1/N with the cut-off frequency multiplied by 1/N respectively. Thus a ratio N<2> is secured between the frequency f0' and the cut-off frequency with the attenuation value multiplied by 1/N<2> for the component of the frequency f0'. When an FG error is detected under such conditions, the f0' component can be set at 1/KX1/N<2>. Thus the detecting accuracy is improved with the FG error.

Title: Insulated gate type bipolar transistor
Inventor: MOMOTA SEIJI
IPC: H01L29/78
Filed: 1990-10-05
Abstract: PURPOSE:To get an IGBT, which reduces switching loss and does not increase on loss, by introducing the carriers, which are discharged during off-time from the high resistance layer corresponding to the base region of the bipolar transistor of the IGBT, to a collector electrode through the switching element to the buffer layer of low resistance of the same conductivity type.

Hereupon, when making a gate signal positive, a signal is also given to the gate of the external transistor 12 to put it in conductive condition. Thereupon, the electrons, which are discharged out of the depletion layer arising after extinction of the electron current of an IGBT, reach the collector electrode 10 via the transistor 12, so the reinplantation of positive holes does not occur, and a tail current can be nearly removed, and turn-off can be reduced.

Title: Ringing suppression circuit
Inventor: SHIBAZAKI KIYOSHIGE
IPC: H04N3/16
Filed: 1987-10-23
Abstract: PURPOSE:To absorb the energy being a cause to ringing by using an active element so as to suppress the dumping vibration generated in the midpoint of a horizontal deflection coil so as to reduce the loss of the deflection current. CONSTITUTION:When a switch element Q1 is turned off by a pulse, a flyback pulse FBP is generated and the dumping vibration being a cause to ringing is generated in the midpoint C of horizontal deflection coils L2, L3. In turning on a dumping vibration absorption switch element Q2 by a pulse of a switch element drive circuit B1, the energy of the midpoint C is divided by a resistor R1, and no vibration is generated and the trailing of the FBP is decreased gradually. However, in keeping the on-state of the element Q2, since the deflection current is consumed, the element is turned off before the video period is started. Thus, the deflection current loss is reduced to absorb the energy being the cause to ringing.

Abstract: PURPOSE:To perform various types of transactions in the proper ratio by calculating the time marks which a reflects the preference ranks of transactions based on the estimated processing time of each transaction and the present time and adding these calculated time marks to the transactions. CONSTITUTION:A processing time estimating device 1 estimates the time required for the end of each transaction. A time mark adding device 2 calculates the proper time mark based on the processing time of a transaction estimated by the device 1 and the present time and adds this calculated time mark to each transaction. Then the device 2 gives a transaction a time mark larger than the time when the transaction is started in consideration of the estimated processing time and based on the desired rank of preference to be given to the transaction. Thus it is possible to eliminate a problem of the time mark system where the possibility of end is reduced as the transaction scale increases. Then various types of transactions can be carried out in the proper ratio.
