Title: Damping device
Inventor: ABE ISAMU
IPC: F16F9/44
Filed: 1991-10-02
Abstract: PURPOSE:To provide a damping device that is equipped with a damper unit capable of easily setting an almost constant specified damping force. CONSTITUTION:A controller controls the opening or closing of solenoid valves 12, 13 and thereby two relief valves 10, 11 installed in oil passages 8, 9 of an oil damper 55 of a damper unit are loaded or unloaded, selecting the extent of damping force in the damper unit. These relief valves 10, 11 operates its opening when each pressure of oil in the oil passages 8, 9 is reached to an open working pressure, and opening is automatically regulated so as to keep the oil pressure almost in the open working pressure. Therefore, even if a relative speed between a cylinder 1 and a piston 2 is varied to some extent, hydraulic pressure in this cylinder 1 comes almost to a constant. Accordingly, an almost constant specified damping force that is almost independent of the relative speed between the piston 2 and the cylinder 1 is easily maintainable.

IPC: B66F9/24
Filed: 1993-10-13
Abstract: PURPOSE:To synchronize the body movement of a fork-lift truck and the face- plate movement of a push-pull device automatically. CONSTITUTION:An amount of body travel is found out by means of counting a pulse number out of a car speed pulse sensor 29 and also an amount of travel of a face-plate 16 is found out by a stroke sensor 28 installed in a hydraulic cylinder 18, whereby an amount of pressure oil supplying into this hydraulic cylinder 18 is automatically adjusted by control of a solenoid control valve so as to make the face-plate travel accord with the body travel. When a limit switch detects a fact that the face-plate 16 is reached to a push stroke end as well as when the limit switch detects the fact that the face-plate 16 is reached to a pull stroke end, a control current into the solenoid control valve 25 is brought to zero, stopping the supply of pressure oil into the hydraulic cylinder 18, and the face-plate 16 is stopped as well.

Title: Image sensor
Inventor: TAKEI AKIRA
IPC: H04N5/369
Filed: 1987-10-09
Abstract: PURPOSE:To detect a maximum or minimum value of the quantity of accumulated electric charges in real time by using two or more resistance changeable means the changes the internal resistance in response to electrical potential signals of each floating electrode that varies in accordance with the quantity of accumulated electric changes. CONSTITUTION:If it is assumed that electric charges are accumulated most in the potential well under the floating electrode 7 shown in figure A, the potential picked out from this floating electrode 7 indicates the lowest potential in the 0V direction. This causes the channel resistance of PMOST21 to decrease and the charging potential of a resistor R21 to decrease. The potential charges in a resistor R21 holds its charging potential unless the channel resistance of PMOST21-T24 changes toward a lower direction than at present. When the channel resistance of PMOST21-T24 changes toward a further lower direction, the charging potential changes toward a lower direction. That is, the potential decrease of the resistor R21 decreases in proportion to the channel resistance of PMOST21, and the channel is in reverse proportion to the light quantity of a resistance light energy P.

In this case, the A-phase inverter output current and the B-phase inverter output current of output signals from the PWM inverter 3A and the PWM inverter 3B with reference to the AC motors 1A, 1B are sampled sequentially, they are A/D converted, and they are fed back to a voltage command part so as to be output as modulating-wave signals. They are sampled separately for the respective AC motors at the timing of the maximum amplitude value of carrier waves, and a sampling operation to the individual AC motors 1A, 1B is performed at the maximum amplitude value of the carrier waves. Thereby, the influence of a current pulsation due to a PWM voltage is reduced, and a current can be controlled with high accuracy.

Filed: 1992-08-31
Abstract: PURPOSE:To reduce the load on a back-up power supply by stopping updating and reducing the time for processing when a voltage drop is detected during rewriting of an upper-digit memory. CONSTITUTION:The most recent integral driving distance data is retained in a memory part 3 by rewriting a memory 31 for lower digit or a memory 32 for upper digit on normal driving. If a battery for power supply is accidentally disconnected, the electric charge of a capacitor for back-up power supply is used temporarily. Especially, although rewriting of a lower digit requires only one word, that of an upper digit requires rewriting of a plurality of words. In this case, when a voltage drop is detected by a voltage drop detection part 5 on rewriting the upper digit, it is transferred to an operation processing part 2, rewriting of the memory part 3 is stopped, and a specific mark is written into an information bit K, thus reducing the time requiring for completing rewriting and hence the load of the back-up power supply as much as possible.
