Title: Fuel injection control device for two-cycle engine
Inventor: UIKE HIROSHI
IPC: F02P5/04
Filed: 1990-06-25
Abstract: PURPOSE:To precisely determine a misfire condition by providing such an arrangement that a detection timing output means retards the detection timing of a pressure in a combustion chamber at least after TDC during operation at a high speed rotational speed so as to detect an indicated pressure upon peak operation. CONSTITUTION:If a two-cycle engine in particular is operated in a high rotation al speed range, in order that the effect of exhaust pulsation is effectively used so as to obtain a high output power, the ignition timing is retarded so as to raise the temperature of an exhaust pipe. As a result, an indicated pressure  PIf becomes smaller so that the determination of a miss-firing comes to be difficult. Accordingly, the PI take-up timing is retarded in accordance with a retardation of the ignition timing or an increase in engine rotational speed Ne. Thus, since the difference  PIF between an indicated pressure PIMO before TDC upon ignition and an indicated pressure PIM1 after TDC becomes sufficient ly larger than the difference  PIM1 between an indicated pressure PIMO before TDC upon miss-firing and an indicated pressure PIM1 after TDC, thereby it is possible to facilitate the determination of misfiring.

Title: Amplifier and operational amplifier
Inventor: KOMORI KENJI
IPC: H03F3/45
Filed: 1994-06-25
Abstract: PURPOSE: To obtain the amplifier in which a dynamic range is high and the frequency characteristic is not deteriorated even at a low voltage power supply. CONSTITUTION: A signal current extracted from a collector of a transistor(TR) Q1 of a differential amplifier pair is given to a current mirror circuit 5 via a constant voltage drop circuit. The signal current is supplied to a load resistor Ro by connecting the constant current source to a collector of an output TR of the current mirror circuit 5. A bias of an output TR Q3 is set freely to be a bias at which a highest dynamic range is obtained by the bias circuit 3. Since almost no signal voltage is generated in the collector of the T1, the frequency characteristic is not deteriorated by a stray capacitance of a Qg.

Title: Solid-state relay
Inventor: HOSOYA KIYOSHI
IPC: H03K17/78
Filed: 1989-06-27
Abstract: PURPOSE:To improve sensitivity and to prevent malfunction to external noise by providing a depression type MOSFET, which is connected between the gate and cathode of an optical ignition thyristor, in an erroneous ignition preventing circuit. CONSTITUTION:The serial circuit of capacitors 5a and 6a for acquiring the control voltage of an MOSFET 7a are parallelly connected to the both ends of an optical ignition thyristor 2a and a connecting point between the capacitors 5a and 6a is connected to the gate of the optical ignition thyristor 2a. When a sharp rising voltage is impressed so that a relay output terminal O1 can be a positive potential to a relay output terminal O2, a transient current flows from an anode to a cathode in the internal part of the optical ignition thyristor 2a. Since the potential of the connecting point between the capacitors 5a and 6a rises up, an impedance between the drain and source of the MOSFET 7a is lowered and since the transient current flows through the MOSFET 7a, the erroneous ignition of the optical ignition thyristor 2a is prevented.

Filed: 1990-06-27
Abstract: PURPOSE:To reduce oil spill to recovery device caused by the foaming of accumulated oil in compressor, by delaying the action of switch valve of refrigerant recovery passage connecting the recovery device and refrigerating cycle. CONSTITUTION:Refrigerant recovery device 12 which is used to recover refrigerant from refrigerating cycle 11, is connected with high pressure charging valve 9 and low pressure charging valve 10 through pipings 13 and 14. In pipings 13 and 14 valves 15 and 16 are equipped respectively. When recovery compressor 19 works, electromagnetic valve 15 is opened and after Tmin passed, electromagnetic valve 16 opens. At the moment of delayed Tmin, because the electromagnetic valve 16 is closed, oil in compressor 1 can not spill out through piping 14. Even if foaming of oil in the low pressure side of compressor 1 happens because of decompression, the oil flows out only to evaporator 5 through piping 7 and can not flow out to the recovery device 12.
