Title: Compound semiconductor photoelectric conversion element on si substrate
Inventor: USUI MASAAKI
IPC: H01L31/10
Filed: 1990-02-27
Abstract: PURPOSE:To permit connection of an external connector without destroying a GaAs solar battery on an Si substrate or degrading its characteristics by forming a welded assembly part of a p-electrode and a welded assembly part of an n-electrode outside the GaAs solar battery itself. CONSTITUTION:A p-electrode 7 is joined to a p-type GaAs layer 4 with a hole opened in ARC 6 and p-type AlGaAs 5 as well as wired on the side of an Si substrate via an insulating film 9 and is further extended continuously to the outside on the same plane as a second principal surface. An-electrode 8 is continuously extended to the outside of the second principal surface on the second principal plane and the same plane as the second principal plane. A welded part 7b of the p-electrode 7 and a welded part 8b of the n-electrode exist outside a GaAs layer of a GaAs solar battery on the Si substrate and the Si substrate. When an external connector is to be welded, thermal and mechanical stress accompanying the welding does not affect the GaAs layer, so that no crack will occur on the GaAs layer as well as no crack of the Si substrate due to the stress will occur.

Title: Magnetic rotation sensor
Inventor: NAKANE KENICHI
IPC: G01B7/30
Filed: 1993-03-10
Abstract: PURPOSE:To protect an epoxy case against crack due to thermal shock by filling the gap between the coil wires of a magnetic rotation sensor with an epoxy resin. CONSTITUTION:Magnetic circuit elements, e.g. a core 1, a magnet 3, a yoke 3, and lead terminals 4a, 4b are integrated with a synthetic resin molded item 6 having a bobbin 6a. A coil 7 is wound around a bobbin provided with a plurality of grooves in the side face 6a' at the coil side flange part of the bobbin 6a and then an epoxy resin is filled in the gap between the windings. This structure suppresses thermal expansion/contraction thus protecting the outer case against crack.

Title: Proportional combustion controlling device
Inventor: INOUE HIROSHI
IPC: F23N1/02
Filed: 1982-03-29
Abstract: PURPOSE:To omit an expensive air rate sensor and to keep air/fuel ratio constant not only in the time of steady operation but also at the time when load is transitionally fluctuated, by adding a very simple delay circuit to a signal circuit on the side of fuel control valve. CONSTITUTION:The signal from a load fluctuation detecting element 1 is compared with a set value and is processed in a comparison operation circuit 2. The output signal from the comparison operation circuit 2 is put into a fuel control valve driving circuit 6, after a constant value as a delay time is added to it when it is determined by the resistance value of a resistor 11 and the capacity of a capacitor 12 in a delay circuit 10 on the side of a fuel control valve 7. Then the fuel control valve 7 is driven by the output value being put out of said driving circuit 6. By this method, the response delay-time of a combustion fan 4 can be equivalently equalized with that of the fuel control valve 7 even when the load is fluctuated. Accordingly, transitional fluctuation of air/fuel ratio can be prevented, together with the incomplete combustion and pulsating combustion.

Title: Optical device for detecting paper
Inventor: HIRAMATSU KAZUHIKO
IPC: G01S17/02
Filed: 1989-03-01
Abstract: PURPOSE:To detect exactly two kinds of paper being different sharply in reflectance or a light-transmitting property by changing over two detection level setting means being different sharply in a paper detection level from each other by a detection level selector switch. CONSTITUTION:In the case of detection of ordinary paper, first a selector switch 6 is changed onto the contact 7 side to put a photosensor 4 in continuity with a volume 9 having a low resistance value. At this time, a detection value of which a current value is large is outputted from the photosensor 4. Since the resistance value of the volume 9 is low, however, the detection value of which the current value is reduced is inputted to a detecting circuit 5. Based on the detection value corrected to be at a prescribed level in this way, the detecting circuit 5 detects the ordinary paper excellently. In the case of detection of an OHP (for overhead projector) sheet, on the other side, the selector switch 6 is changed onto the contact 8 side to put the photosensor 4 in continuity with a volume 10 having a high resistance value. Thereby a detection value of which a current value is at the same level as the one of the detection value of the ordinary paper is inputted to the detecting circuit 5 and thus the detecting circuit 5 can detect also the OHP sheet excellently.

A temperature of the evaporator is detected by its special purpose temperature detecting means 15. Further, the air in the refrigerator is circulated by a circulating fan 12a while heat exchanging the air in the refrigerator with the evaporator. In this case, an outdoor temperature is detected by atmospheric temperature detecting means 19. At an initial time of energizing a power source, when detected temperatures of the evaporator and the atmosphere are equal to or higher than predetermined temperatures, the fan 9a is operated at higher number of revolutions than a normal value in synchronization with the operation of the compressor 7. Then, the fan 12a is operated at lower number of revolutions than the normal value only for a predetermined time.

Filed: 1988-03-03
Abstract: PURPOSE:To reduce the discharging voltage and improve the durability by forming a semiconductor layer with a specific resistance value by diffusion and sintering separately from a center electrode in connection to or separately from a fitting metal on the surface of an insulator. CONSTITUTION:An insulator 3 fixed with a center electrode 2 in the axis hole while its tip is exposed is inserted into a cylindrical fitting metal 1 constituting an outside electrode 11 at the tip face so that the tip face of this insulator is located at the back of the tip face of the fitting metal 1, a spark discharge gap 7 including a creeping discharge gap 4 is formed between the center electrode 2 and the outside electrode 11. A semiconductor layer 6 with a resistance value of 1-300MOMEGA is formed by diffusion and sintering separately from the center electrode 2 and in connection to or separately from the fitting metal 1 on the surface of the insulator 3. When the negative high voltage is applied to the center electrode 2, a current flowing along the outer periphery 33 occurs, the ionization of the gas in the creeping discharge gap 4 is accelerated. The spark discharge with the low voltage at the spark discharge gap 7 can occur, thereby the semiconductor layer 6 is hardly deteriorated by heat, and excellent durability is obtained.

Title: System for controlling blocking of communication

IPC: H04Q1/20
Filed: 1982-03-29
Abstract: PURPOSE:To suppress malfunction due to the insertion of a package by generating false failure state in a required communication system part forcedly at the insertion of the package and blocking the communication system part. CONSTITUTION:When insertion of a maintenance package is required, a switch 12 is turned on and a bufferful flip-flop (FF) is turned on. After that time, the output of the FF11 is kept at a high level, so that a central processor 1 always detecting the state of the output signal decides as if a failure is generated in the communication line and blocks the communication line. Consequently a disturbance signal generated at the removal of the package is not transmitted to the CP1 through a bus, preventing the CP1 from malfunction.
