Patent JP-S63283073-A (JP)
Title: Semiconductor pressure sensor
Inventor: OHATA SATORU
IPC: H01L29/84
Filed: 1987-05-15
Abstract: PURPOSE:To suppress a mutual thermal interference between a piezoresistance element and a temperature-sensing element thanks to an action by a low thermal-conductivity part to reduce the thermal interference by a method wherein the low thermal- conductivity part is installed between a diaphragm part and the temperature-sensing element. CONSTITUTION:A groove 9 is formed at the rear surface of an Si substrate 1 between a diaphragm part 2 and a third-layer part 8 where a temperature-sensing element 7 is formed. Because the groove 9 functions as a low thermal-conductivity part, a thermal influence by the temperature-sensing element 7 as a heat source installed on the thick-layer part 8 to be remote from the groove 9 becomes small with reference to piezoresistance elements 3-6 which are installed on the surface of the diaphragm part 2 acting as a distortion-causing part. In addition, the groove functions in such a way that an influence by the heat generated at the distortion-causing part or by the distortion due to the impressed pressure is hardly transmitted to the temperature- sensing element 7 formed at the thick-layer part 7. Thanks to an action by the groove 9 to reduce a thermal interference a change in temperature at a zero point of a bridge constituted by the piezoresistance elements 3-6 does not cause any hysteresis; a characteristic corresponding to a change in the external temperature is obtained.

Title: Electronically controlled fuel injection process in internal-combustion engine and equipment
Inventor: KOBAYASHI NOBUYUKI
IPC: F02D41/10
Filed: 1981-07-24
Abstract: PURPOSE:To reliably prevent the engine from its bad condition due to the abnormality of the increment in the low temperature in such a way that in a structure that fuel injection rate is compensated in response to the condition in the engine, etc., the upper limit value to the total of the increment in the low temperature is determined as the function for the engine cooling water. CONSTITUTION:During ordinary operation, an electronic control circuit 38 computes the reference injection time Tp through each output from an air-flow meter 12 and a distributor 14, and the effective synchronous injection time tau1 is computed by compensating said time Tp in response to signals from other various sensors 16, 22, etc. Besides, an injection valve 36 is controlled by computing the synchronous injection time taus in such a way that the unavailable injection time tauv which is found out when the battery voltage is abated is added to the stated time tau1. Hereat, the control circuit 38 also compensates the injection time by storing the sum of the increment after starting, accelerating increment when warming up, overheat increment and increment as the upper limit value to the sum of the increment in the low temperature to a register using the upper limit value as the function of the cooling water temperature.

Title: Optical signal reception circuit
Inventor: UEMATSU HIROHARU
IPC: H04B10/40
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To limit a current to flow to a light receiving element by separating an average optical input level expressed by a DC component in an electric signal from the light receiving element and lowering a bias voltage from a voltage supply means when the average input level is higher than a prescribed level. SOLUTION: At DC separation part 19 of protection circuit 17, the DC voltage of electric signal is separated and the signal level of separated DC component corresponds to the average optical input level and is inputted to an amplifier circuit 21. The average optical input level inputted to the amplifier circuit 21 is amplified and outputted to the base of transistor 23. When the average optical input level higher than the prescribed level is inputted to the base of transistor 23, corresponding to the average optical input level, a current flows between a collector and an emitter. As a result, an output voltage from a driving circuit regulation circuit 15 to a driving circuit 13 is lowered, and the driving circuit 13 lowers the bias voltage of avalanche photodiode(APD) 3 and lowers a current to flow to the APD 3.

Title: Fault detecting method for matrix-like touch switch of copying machine
Inventor: MIYAWAKI SHOZO
IPC: G03G21/00
Filed: 1987-05-15
Abstract: PURPOSE:To improve the operability, the maintenance property, etc., by storing a switch holding continuously an operating state for a longer time than a value determined by a narrower range than a prescribed vale, in assuming the switch as being disconnected, in a ROM, and disregarding this switch at the time of deciding a depression of the switch. CONSTITUTION:A voltage is applied successively from output side 13-1, 13-2...13-m of a matrix, and the quality is decided by read data from input sides 14-1, 14-2...14-n. Subsequently, a state which has been pushed with a finger is decided from a part of a pressing part 15, and in case of a switch fault, an electric conduction is an isolated point, and also, an operating state is held continuously in a ROM for a longer time than a value determined by a narrower range than a prescribed value. On the other hand, in case of a normal depressing operation by a operator, the switch is energized within some range. Accordingly, in case of a fault, by disregarding a faulty part and using the switch as usual, the operability, the maintenance property and the productivity can be improved.

Title: Numerical controller
Inventor: ISHIHARA TOSHIO
IPC: G05B19/416
Filed: 1993-05-19
Abstract: PURPOSE:To make the controller possible to give a command on a motor torque control method by a simple NC part program in order to perform the shaft feeding while keeping a constant motor torque. CONSTITUTION:When a follow-up error comparing part 16 decides that a follow-up error is larger than its allowable value, a speed comparing part 17 compares the detecting position change value DELTAAPA per unit time with a feeding command speed DELTAF. If the speed DELTAF is larger than the value DELTAAPA, the present function generating position CONn of the feeding shaft is set at the value obtained by adding the value DELTAAPA to the precedent function generating position CONn-1 of the feeding shaft. Thus, the follow-up error can be kept at the value less than a fixed level.

Title: Optical output device
Inventor: SUNAGA YOSHINORI
IPC: H04B10/071
Filed: 1992-05-11
Abstract: PURPOSE:To maximize the output in a range in which a transmission light is not wasted by separating a reflected light returning from an optical fiber to the optical output device, detecting the separated reflected light and controlling a transmission optical level based on the detected output. CONSTITUTION:An optical signal outputted from a fiber type optical amplifier 40 passes through an optical circulator 50 and is outputted to an optical fiber 10. A reflected light mainly caused by stimulated brillouin scattering is generated in the inside of the fiber 10 and returns in the direction of an optical transmitter 21. The progressing direction of the reflected light is changed by the circulator 50 and made incident on a photodetector 6. A controller 70 decreases a current of a stimulation semiconductor laser of the amplifier 40 when the reflected luminous quantity is more than the setting value based on the information of the reflected luminous quantity outputted from a detector 60 to limit the output. Waste of power consumption is prevented by deciding the amplification factor of the amplifier 40 to suppress the reflected light to be the setting value or below thereby limiting the optical output and extending the service life of the semiconductor laser.
