Title: Solenoid valve driving circuit
Inventor: TSUTSUI OSAMU
IPC: F16K31/06
Filed: 1988-09-21
Abstract: PURPOSE:To make the excitation time nearly constant regardless of an increase of the internal resistance of a battery by providing a capacitor feeding a current to a solenoid when a switch is closed in parallel with a serial circuit of the switch and the solenoid. CONSTITUTION:When a switch 3 is opened, a capacitor C is charged until its voltage becomes equal to the voltage E of a battery 1. When the switch 3 is closed by a switch driving circuit 4 under this condition, a current from the capacitor C mainly flows through a solenoid 2, and the voltage drop due to the internal resistance of the battery is reduced. When the solenoid drive completion time t1 elapses, the switch 3 is opened by the switch driving circuit 4, then charges are gradually stored again in the capacitor C from the battery 1 via a resistor R to prepare for the next drive of the solenoid valve. A nearly constant current value is secured regardless of the size of the internal resistance of the battery, the excitation quantity can be made nearly constant, and the power consumption can be improved.

Title: Steering system for vehicle
Inventor: NAGAOKA MITSURU
IPC: B62D137/00
Filed: 1992-09-04
Abstract: PURPOSE:To moderate or prevent the sudden turning action of a vehicle at the time of an accelerator pedal being return-operated by a driver in the power under-steer state in the case of controlling the steering of front wheels or rear wheels according to front wheel steering in a front wheel drive vehicle. CONSTITUTION:A steering means 20 steers rear wheels, and a control means 30 computes the target control quantity to rear wheel steering on the basis of the state quantity of a vehicle such as the actual yaw rate, a front wheel steering angle and the estimated side slip angle of the wheel so as to control the steering means 20 by the control quantity. A driving force detecting means 33 detects the time of the slip ratio of the front wheel to the rear wheel being the set value or more, as the power under-steer state. In the power under-steer state, the control means 30 controls the rear wheel into the specified steering angle of opposite phase to the front wheel in order to compensate the under- steer state, but a regulating means 34 receives the output of the driving force detecting means 33 and limits-regulates the opposite phase control of the rear wheel performed by the control means 30 at the time of the power under-steer state.

Title: Semiconductor storage device and manufacture thereof
Inventor: NISHIMOTO TOSHIO
IPC: H01L21/8229
Filed: 1990-09-07
Abstract: PURPOSE:To store a plurality of informations and to perform a semiconductor storage device having a small chip size by storing the informations by the type of a P-N junction area. CONSTITUTION:When an address is input, a word line WL1 1 and a bit line BL1 3 are selected, the selected line WL1 1 becomes a low level, and a nonselected line BL2 4 also becomes a low level. In this case, a current flows in a memory cell M1 since the line 3 is connected to the line 1 with a low impedance. On the other hand, no current flows in a memory cell M2 since both the lines 4 and 1 are low levels. Since a P-N junction is connected reversely, the current of the cell M1 does not reversely flow to a memory cell M2. Since a word line 2 is a high level, memory cells M3, M4 have no current flowing from the lines 3, 4 to the line 2. This is sensed and amplified by a current sensor to obtain an output. Thus, the size of the memory cell per one can be reduced.

Filed: 1989-09-13
Abstract: PURPOSE:To make it possible to set easily even an alarm area in a complicated shape and to simplify a construction by designating the alarm area for a displayed radar image by adding a memory for alarm to a raster scan radar. CONSTITUTION:In an ordinary detection mode, a memory 24 for alarm is also accessed and read through a selector 29 by a reading address of a reading address generating circuit 21 and a read output of the memory 24 for alarm is compared with a read output of a radar image memory 16 in a comparator circuit 31. When alarm data '1' is read out and when the read output of the radar image memory 16 is a prescribed value or above, an alarm signal is generated. This alarm signal is supplied to a control element 11, and when the control element 11 receives the alarm signal, it sounds a buzzer and makes the display of a reflected wave flicker. In this case, even an alarm area in a complicated shape can be set easily and a construction is simplified.

Title: Operational amplifier
Inventor: SAKURAI KATSUTO
IPC: H03F3/45
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To realize a high speed operation and to reduce consumption current by varying the bias current of an output state buffer in accordance with differential voltage between a normal input terminal and an inverted input terminal. SOLUTION: The output of an operational amplifier 1 is inputted to an output stage buffer 3, is impedance-converted and is outputted to an output terminal 7. A signal detected by a differential voltage detection means 2 detecting differential voltage between the normal input terminal 5 and the inverted input terminal 6 in the operational amplifier 1 is inputted to the output stage buffer 3 and it becomes a control signal for varying the bias current of the output stage buffer 3. When the input voltage of the normal input terminal 5 is higher than the input voltage of the inverted input terminal 6, the bias current of the output stage buffer 3 is varied so that the voltage of the output terminal 7 improves the driving ability of a side where the voltage of the output terminal 7 rises.  When normal input voltage is lower than inverted input voltage, the bias current of the output stage buffer 3 is varied so that it improves the sink ability of a side where the voltage of the output terminal 7 drops.

Abstract: PURPOSE:To simplify the labor of copying work and to improve workability by reading out and storing copying information such as the legality/illegality of a copy and copying the required number of sheets of each original described in original paper. CONSTITUTION:When a start switch 18 is depressed, light emitting elements L1-L9 corresponding to 9 document distributing addresses e.g. are emitted by a command from a CPU17 and photodetecting elements S1-S9 read out the legality/illegality of distribution printed out in the original and inputs the read-out result to a CPU17. The CPU17 totalizes the required number of sheets previously fixed on respective distribution addresses at necessary parts and displays 20 the totalized result and then the copying machine continuously copies the required number of sheets. A sorter part 21 in the CPU17 controls a pin control circuit 22 and a pin driving means part 23 to deliver the required number of sheets for each address to be distributed to a prescribed tray and sorts and stores the prescribed number of sheets in the tray. Thus, the copying work is rationalized.
