Title: Miss-fire detecting device for multicylinder internal combustion engine
Inventor: OSAWA KOICHI
IPC: F02D45/00
Filed: 1991-07-19
Abstract: PURPOSE:To perform reliable detection of the occurrence of a miss-fire without being influenced by vibration of an engine body. CONSTITUTION:A miss-fire detecting device for a multicylinder internal combustion engine is provided with a rotor 11 rotated in synchronism with an engine crank shaft 10 and a sensor 12 fixed on the engine body side and detecting the angular velocity of the crank shaft 10 in coordination with the rotor 11 fixed on the engine body side. Based on an output signal from the sensor 12, the rate of change of the angular velocity of the crank shaft 10 is calculated and when the rate of change of the angular velocity of the crank shaft 10 is changed into a value higher than a predetermined set amount, it is decided that a miss-fire occurs. An operation region wherein violent vibration of an engine body is produced around the crank shaft 10 is previously stored, and when the running state of an engine is in the operation region, decision of the occurrence of a miss-fire is prohibited or a set amount is increased.

Title: Air bag gas generator and air bag device
Inventor: YAMAZAKI MASAYUKI
IPC: B60R21/26
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To lower a maxim surface temperature of a diffuser in an outer shell container by providing a thermal transmission regulating means reducing transmission of heat generated by combustion of a gas generating means to the diffuser shell side in comparison with that to the closure shell side. SOLUTION: When ignition powder 5 is burnt by means of an igniter 4 operated by an impact, a fire breaks a seal tape 27 closing an inflammation hole 26 in an inner cylinder agent 13 and flows into a combustion chamber 22. A gas generating agent 6 in the combustion chamber 22 is burnt by a fire of the ignition powder 5 so as to generate gas. The gas is purified and cooled while it passes through a coolant filter 7, passes through a clearance 9, and breaks a seal tape 25 in a gas exhaust port 11 so as to be discharged. As a clearance part is arranged between a diffuser shell 1 and the coolant filter 7, heat transmission can be prevented. A maximum surface temperature of the diffuser shell 1 after combustion of the gas generating agent 5 can be reduced below that of the closure shell 2.

Title: Phase locking circuit
Inventor: OKINO TAKAYUKI
IPC: H03L7/087
Filed: 1983-09-28
Abstract: PURPOSE:To always perform stable control, by providing a pulse generator which is triggered by an input signal and generates a pulse signal having a pulse duty of about 1/2 against the input signal between an input and a phase- lead-lag detector. CONSTITUTION:A pulse generator 9 is triggered by an input signal fin and, when the cycle is represented as T, generates a pulse signal output f'in of a pulse width of about 1/2T. A phase-lead-lag detector 4 compares the phase of the output f'in with that of the output signal fput of a voltage controlled oscillator 3 and the obtained error signal is integrated by an integrator 5 having a sufficiently long time constant. On the other hand, a phase comparator 1 compares the phase of the signal fin with that of the oscillator output fout and the obtained error signal is smoothed by an LPF2. An adder 6 adds the output of the LPF2 to the output of the integrator 5 and the added output controls the oscillator 3 and issues the output signal fout.

Title: Touch switch
Inventor: FUNAHARA HISAO
IPC: H03K17/96
Filed: 1988-07-19
Abstract: PURPOSE:To improve the temperature stability by providing a feedback path comprising an inverse amplifier, a contact plate, a capacitor and two resistors so as to act the contact plate as an equivalent capacitor. CONSTITUTION:Two resistors R1, R2 connected in series are connected between an output terminal and an inverting input terminal (a) of an inverse amplifier Z, a capacitor C is connected between the connecting point of the resistors R1, R2 and the ground terminal and the contact plate P is connected to the inverting input terminal (a). Thus, even if a human body P is in contact with the contact plate P and a capacitance is caused with the common path, the oscillation circuit is oscillated in terms of the 2nd order differential equation. Then each circuit constant is decided so that a 2nd order differential equation has oscillatory solutions. Thus, the temperature stability is enhanced and even if the amplifier chip is heated by using a solder iron, the oscillated amplitude does not cause the temperature instability.

Abstract: PURPOSE:To prevent an overrich zone of air-fuel ratio from appearing in every operating region by partly opening a movable valve, which variably controls the passage area of a Venturi part, being associated with a throttle valve when its opening increases to a predetermined value or more. CONSTITUTION:When a throttle valve 3, provided in an intake cylinder 2 in a carburetor main unit 1, increases the opening and a flow amount of air in a Venturi part 5, metered fuel in a primary main jet 10 is mixed with the metered air in a primary main air bleed 9, and the mixture is jetted to the Venturi part 5 from a primary main nozzle 8. When the opening of the throttle valve 3 reaches a predetermined value, a cam plate 31, constituting an interlocking means 30, engages a cam surface 31a with a pawl part 32 of a lever 13, partly opening a movable valve 11. As the result, the Venturi part 5 increases its passage area, suppressing a Venturi negative pressure from increasing to the predetermined value or more. Thereafter, fuel is sucked from a secondary main nozzle 17.

Title: Fuel injection device
Inventor: KUBO HIROMASA
IPC: F02D41/04
Filed: 1982-10-15
Abstract: PURPOSE:To obtain the optimum efficiency of combustion of an engine and improve its startability and drivability, by changing an injection period by a control unit on the basis of a fuel temperature signal from a sensor in the vicinity of injection nozzles so as to inject a required amount of fuel for the engine without an influence by the temperature of fuel. CONSTITUTION:A control unit 48 calculates the optimum timing and period of fuel injection for an operational condition on the basis of a signal showing the operational condition of a vehicle such as engine speed signal, intake air quantity signal, crank angle signal, etc. Then on the basis of a fuel temperature signal from a fuel temperature sensor 39, the pulse width of a fuel injection signal, that is, an injection period is adjustably corrected. Accordingly, the total amount of fuel injected from nozzles 36 is not influenced by a change of fuel temperature, causing the nozzle to always inject the amount of fuel required for an engine. As a result, the optimum efficiency of combustion can be always obtained, capable of improving startability and drivability of the engine.
