Patent JP-S63248948-A (JP)
Title: Fuel supply control device for on-vehicle internal combustion engine
Inventor: ISHIKAWA KEIICHI
IPC: F02D41/12
Filed: 1987-04-06
Abstract: PURPOSE:To prevent engine stop, in the case where the degree of change in a vehicle speed is increased when the number of revolutions of the engine is decreasing as the vehicle speed decreases, by causing the return to fuel supply even if the operating conditions of fuel-cut are fulfilled, and further by carrying out an increasing correction. CONSTITUTION:When it is judged by an ECU 5, during the operation of an engine 1, that the engine is in a prescribed decelerating operating condition, the cutoff of fuel supply (fuel cutoff) to a fuel injection valve 6 is carried out, and then, when the number of revolutions of the engine detected by an engine revolution sensor 10 becomes lower than a prescribed number of revolutions, the return to fuel supply is carried out. And when this is carried out, the fuel supply quantity is corrected so as to be increased. On the other hand, it is so constituted that the degree of change in the vehicle speed detected by a vehicle speed sensor 13 is detected to make it possible to release fuel cut depending on the degree of the change even if the operating conditions of fuel- out are fulfilled, and when the fuel cut is released, the supply quantity of fuel is simultaneously corrected so as to be increased.

Filed: 1992-04-07
Abstract: PURPOSE:To make system operation increasingly easier for users as they get used to operation. CONSTITUTION:A knowledge base access part 8 opens a knowledge base part 7 and inputs sentences from an input part 1. A syntax analysis part 2 analyzes the syntax, and an operation change judge part 5 judges the change of the operation. When the operation is not changed, the sentences are preserved in a temporary user input preservation part 3, the knowledge base access part 8 selects action from the knowledge base part 7 or a sense information preservation part 9, and the action is preserved in a temporary action content preservation part 11 and outputted by an output part 12. When the operation is changed, the knowledge base access part 8 constructs the contents of the temporary user input preservation part 3 in the knowledge base part 7, a temporary user input preservation part clear part 4 clears the temporary user input preservation part 3, and a temporary action content preservation part clear part 10 clears the temporary action content preservation part 11. An end judge part 6 judges whether the operation ends or not, when the operation does not end, the operation moves to the temporary user input preservation part 3 and when the operation ends, it is finished by closing the knowledge base part 7.

Title: Tape recorder
Inventor: NOJIMA HIDEAKI
IPC: G11B5/027
Filed: 1983-05-13
Abstract: PURPOSE:To control a plunger driving circuit for inversion of tape driving and a muting circuit for reproduction signal with a simple constitution, by supplying the signal of a detecting circuit which produces a pulse signal when the take-up operation is through with the tape or a manual reverse operation mode to a control circuit to deliver two control signals. CONSTITUTION:One of the signals sound recorded on a magnetic tape in a tape play mode is supplied to a speaker 8 for headphone through a remote control switch 7; while the other signal is connected to a termination detection switch 12. The voltage lower than VBE and the voltage approximately equal to the level of power supply voltage are produced when switches 7 and 12 are short-circuited and opened, respectively. Thus a pulse signal can be detected. A control circuit 15 consisting of a transistor TR2 and a resistance R7 is used in common to a muting circuit 9 and a plunger driving circuit 14. The circuit 15 is actuated even in a reverse mode during the reproduction of tape when the switch 7 is manually operated since the switches 7 and 12 are connected in series. Thus the circuit 14 is driven and at the same time the muting is performed with a low frequency signal.

Filed: 1980-06-20
Abstract: PURPOSE: To prevent the detection mistake and erroneous correction at the decoding of the next stage, by making the correction limited to one word error at the decoding of the first stage.  
     CONSTITUTION: The decoding of the 1st stage to the 2nd error correction block is made, and the PCM data series of a plurality of channels and the 1st check word series are delayed with different time for channel.

Title: Switch mechanism
Inventor: SUGITA SATORU
IPC: H01H3/60
Filed: 1990-03-30
Abstract: PURPOSE:To prevent a switch inside a switch mechanism from being broken even if an excessive force or a buffering force is carelessly exerted on the switch mechanism by providing a control member with a buffering means. CONSTITUTION:A buffering mechanism 4 comprising a spring serving as a buffering means is provided at the end of a switch button 1 and is given an appropriate spring constant (k) in order to prevent an excessive load or buffer load from being directly transmitted to a tact switch 5. When the switch button 1 is pushed in the direction of the arrow the pushing force is cancelled out by the buffering mechanism 4 and then a pushing force is exerted on the tact switch 5 whereby predetermined switching operation is completed. The tact switch 5 will thus not be broken even if a pushing force is exerted on the switch 1 excessively or in a buffering manner.

Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide an electrically controlled mechanical timepiece the duration of which can be prolonged, by reducing the occurrence of eddy current losses in members arranged around a rotor. SOLUTION: The whole body of each bearing unit 19 including the part corresponding to the arranging hole 21a of a stator 21 is constituted of an end stone 19a, a hole jewel 19b, and an end stone guide 19c made of insulators.

Abstract: PURPOSE:To prevent the start running of a vehicle in a steering direction at the time of recovery of the grip force of a wheel by increasing a brake liquid pressure for wheel cylinder, when it is judged by an irregular turning judging means, that a vehicle is in an irregular turning state during braking. CONSTITUTION:During the running of a vehicle, a wheel acceleration alphaW of each wheel 20 is calculated based on the output of a wheel speed sensor 30 in a wheel acceleration calculation unit 12 in ECU 10 and a running speed in pedaling a brake pedal is estimated as a pseudo-wheel speed V1 based on a wheel speed detection signal in a pseudo-wheel speed setter 14 and these values are outputted to a brake liquid pressure selection unit 16.

IPC: C02F1/28
Filed: 1985-04-19
Abstract: PURPOSE:To remove effectively oil including water-soluble oil or COD in waste water by bringing waste water into contact with coal or coke having specified grain size. CONSTITUTION:Waste water is brought into contact with coal or coke having <=5mm grain size in a mixing tank or an adsorption tower. Namely, since coal or coke having excellent physical and chemical adsoptive power and also having high adsorptive power to a substance having strong polarity is used, oil or COD in industrial waste water can be effectively treated, coal or coke, an adsorbent, obtained only by crushing already oxidized coal or coke in specified grain size need not be reactivated unlike activated carbon and hence is far cheaper than activated carbon, a compound and multistage apparatus is not necessitated and water-soluble oil can be removed with high efficiency with a simple means such as mixing.
