Patent JP-S5841233-A (JP)
Title: Fuel injecting apparatus for internal-combustion engine
Inventor: UCHINAMI MASANOBU
IPC: F02D41/10
Filed: 1981-09-03
Abstract: PURPOSE:To eliminate delay of fuel supply at the time of rapid acceleration of an engine, by opening a plurality of injection valves independently by generating fuel increasing pulses in synchronism with pulse signals produced when a signal relating to the opening of a throttle valve or an electric signal produced by a signal related to said throttle opening signal becomes higher than a prescribed value. CONSTITUTION:When a throttle valve is opened rapidly for the purpose of accelerating an engine, a comparison circuit 13 produces an output signal since a differentiation circuit 12 produces a voltage higher than a prescribed voltage VE. While the output signal is produced from the circuit 13, a throttle signal C exceeds voltages V2, V3 predetermined in relation with the opening of the throttle valve, and an output signal of a pulse generating circuit 11 started by respective output signals of comparators 9, 8 is given to a driving circuit 3 via an AND-circuit 14, whereupon the circuit 3 opens an injection valve 1 only for the while determined by the pulse generating circuit 11 for injecting fuel. Therefore, it is enabled to open the valve 1 without delay of time even if rapid acceleration is made between the intervals of injection pulses that are produced in synchronism with ignition signals produced from a control unit 2.

Title: Individual collating method
Inventor: TAKINAMI KOUJI
IPC: G06Q40/00
Filed: 1982-08-11
Abstract: PURPOSE:To prevent an ID card from being used illegally by using voice data characteristic of an individual for an individual collating method. CONSTITUTION:A customer inserts an ID card in a reader/writer 1 and inputs a collation specification and a registered number on a keyboard 2. When the input from the customer indicates collation, a computer 4 presses voices of the same word as that inputted during registration. The voiced word is read to extract a PARCOR coefficient and pitch. Then, the PARCOR coefficient registered on the ID card is read by the reader/writer. Then, distance is calculated together with the pitch of a memory 5. When the distance is less than a predetermined threshold value, the customer is judged to be registered and necessary service is offered; when greater, the customer is judged as a false person.

Title: Piezoelectric speaker driving circuit
Inventor: TAKAZAWA KAZUHISA
IPC: H04R17/00
Filed: 1981-09-07
Abstract: PURPOSE:To prevent elements in a circuit from breakdown by connecting a resistor to an NMOS of a CMOS driver. CONSTITUTION:If an abnormal voltage is generated due to shock, a current flows a path A when a positive voltage is generated at one end of a B-TR4 of a piezoelectric speaker 6. In this case, a reverse bias is given between the collector and the base of the B-TR4 and the current does not flow to other parts. When a negative voltage is generated at the said one end of the piezoelectric speaker 6, a current flows the paths of B, C and D. In this case, the B-TR4 performs inverse operation, and a current flows from the base to the collector and from the emitter to the collector. If the current in the path B is too excessive, an NMOS1 might be brokendown, but the current can be suppressed with a resistor 3. Since the current in the bus B is suppressed, the current in the path C can be suppressed to some extent.

Filed: 1990-05-29
Abstract: PURPOSE:To prevent the operation defect of a drainage solenoid valve and the reduction of a drainage stroke from occurring without acting a force of pinch on a connecting plate and the drainage solenoid valve by applying the reaction force of a braking lever so as to function on the operating shaft of a drainage valve and the drainage solenoid valve in a state where a brake is released. CONSTITUTION:The shape of the contact part of the braking lever is formed in curved shape extending over from an operation member point when the brake is applied to an operation member contact point when the brake is released so that the contact point of an operation member provided at the connecting plate 40 for drainage valve opening/closing and the contact part of the braking lever 34 for brake turning can always be located on the operating shaft of the drainage valve and the drainage solenoid valve. The reaction force of the braking lever 34 is comprised so that it can be operated on the operating shaft of the drainage valve and the drainage solenoid valve 41 in the state where the brake is released, and also is comprised so that a component force in an outside direction does not exist. Thereby, since a force pressing the braking lever can be always located at the operating shaft of the drainage valve and the drainage solenoid valve, no force pressing the operation member in the outside direction occurs, and no pressing of the connecting plate to the outside occurs.

Title: Belt tension controller
Inventor: TOMITA TAMAKI
IPC: F16H7/08
Filed: 1977-11-24
Abstract: PURPOSE: A power transmission system which prevents seizure of a hydraulic bearing by releasing sluid pressure of a motor-bed-mounted belt tension fluid pressure  cylinder at the time when the system is switched off to cut off the pressure oil which is supplied for the hydraulic bearing of the rotation shaft by a motor-drive hydraulic pump.  
     CONSTITUTION: A rotation shaft 12, running through a hydraulic bearing applied with fluid pressure by a hydraulic pump operated by a motor not illustrated, is kept by a supporter 10 and driven by a motor 15 with the aid of pulleys 16, 18 and a belt 17. When supply is off, dimagnetized solenoid SOL changes over a switch valve 22 to releases the fluid pressure from a belt tension fluid pressure cylinder 20 dontained in a motor bed 14 so the belt is lossened. As the rotation shaft 12 makes innertia rotation due to not so great belt tension applied, the hydraulic bearing loaded with no fluid pressure can be prevented from seizure.
