Title: Semiconductor memory device
Inventor: KATSUNO KUNIO
IPC: G11C17/18
Filed: 1984-02-06
Abstract: PURPOSE:To reduce short circuit current running in a sensor amplifier by changing rapidly an input potential of a sensor amplifier after a sensor amplifier output is inverted. CONSTITUTION:When a precharge command signal is inputted, an output signal of a synthesizing circuit is inverted, and a transistor 46 is brought to the nonconductive condition. At the same time, a transistor for precharge is brought to the conductive condition, and the precharge is started. When the precharge command signal is inverted after a certain period has expired, the precharge is completed. When memory is in the conductive condition, a charge to be charged in an input line 10 of a sensor amplifier is discharged. A potential of the input line 10 of a sensor amplifier approximates to that to the 3rd electrode 36 again and intersects a logic level of a sensor amplifier. As a result, an output of a synthesizing circuit is again inverted, and the transistor 46 is brought to the conductive condition. Consequently, the input line 10 of a sensor amplifier is rapidly drawn by a potential of the 2nd electrode, a sensor amplifier input is suddenly changed, and the short circuit current is reduced.

Filed: 1984-02-06
Abstract: PURPOSE:To implement a closing test simply and equivalently for all points of a multi-point breaker by closing a power source through all breaking points after impedances for sharing voltage noticeably uneven in the impedance value are connected in parallel to respective breaking points. CONSTITUTION:Impedances 2a-2d for sharing voltage are connected in parallel to breaking points 1a-1d of a multi-point breaker 1 and the impedance values Za-Zd thereof are set at Za>Zb>Zc>Zd. A voltage is applied to the breaker 1 through a current limiting reactor from a power source equipment 3 to perform a closing operation. The voltage by the power source equipment 3 is mostly applied to the first breaking point 1a because of the values of the impedances 2a-2d, to discharge this pole initially. Instantly discharge is done at the breaking point 1a, the whole voltage is applied to the second breaking point 1b to discharge this pole. Likewise, discharges are done at the breaking points 1c and 1d and a closed current flows through the multi-point breaker 1.

Title: Suspension device for vehicle
Inventor: YOSHIOKA TORU
IPC: F16F9/46
Filed: 1991-02-14
Abstract: PURPOSE:To prevent traveling stability from lowering even if a stepping motor becomes out-of-step by compensating the out-of-step of a stepping motor for altering a damping force of shock absorbers so that a control means compensates the damping force to a harder side for a specified time interval. CONSTITUTION:A control unit 8 detects a damping force at pressure sensors 61 to 64 of their respective shock absorbers, and inputs acceleration signals in vertical direction of a spring weight from acceleration sensors 11 to 14, and signals from a vehicle speed sensor 15. When a control mode is selected by a mode selection switch, the control unit 8 calculates a sky hook damping force of ideal damping force, and changes the coefficient of damping one step harder than before according to the detected damping force. Then, it outputs control signals to actuators 41 to 44, and changes the damping force of the shock absorbers by one step by a stepping motor. Thus, lowering of traveling stability can be prevented even if the stepping motor becomes out-of-step.

Abstract: PURPOSE:To maintain a stable rotation by making controllable a gyro moment which is generated in the direction perpendicular to a displacement caused to the rotating shaft by an external disturbance almost at the same time as this displacement occurs, when using a 4-shaft suction control type magnetic bearing device which has two radial bearings. CONSTITUTION:At both ends of the rotating shaft, electromagnets 1 (1a-1d, 1e-1h) are arranged radially, and the rotating shaft is supported in the air by the magnetic sucking force of the electromagnets 1. Then, from the displacement deviation of the magnetic sucking force acting point, each displacement deviation in the vertical and horizontal directions of the gravity center G of the rotating shaft and the deflection angles theta, phi about the gravity center are calculated. Next, each electromagnet 1 is controlled to control the force which acts on the gravity center and the torque about the gravity center so that the above displacement deviations and the deflection angles theta, phi will be zero. And at this time, the value obtained by multiplying the number of the rotating shaft revolutions by the coefficient is multiplied by the value obtained by differentiating the deflection angles theta, phi, and the resulting signal is added to the torque order of one radial bearing and is subtracted from the torque order of the other radial bearing.
