Title: System stabilizer
Inventor: NAKAMURA TADASHI
IPC: H02J3/24
Filed: 1995-04-07
Abstract: PURPOSE: To make it possible to provide proper stabilization control even at the time of variation in power flow, reclosing or following fault, by, if the occurrence of a system fault is detected, locking stabilizing operation for a certain time and performing stabilization control operation based on the power flow immediately before the occurrence of the fault. CONSTITUTION: When a one-shot timer 12 receives output from a fault detecting relay 11, it produces output for a certain time and the output is an operation lock signal. When the operation lock signal is '0', a stabilizing operation unit 14 performs arithmetic operation in a certain cycle based on power flow at a point before the present point by a time delayed by a short-time delay circuit 13. When the operation lock signal is '1', the operation unit 14 locks stabilizing operation and holds the result of the present arithmetic operation. The time delayed by the short-time delay circuit 13 is as short as a few milliseconds or so. This makes it possible to perform proper stabilization control operation based on power flow immediately before the occurrence of a fault even at the tie of variation in prior power flow, reclosing or following fault.

Filed: 1995-04-07
Abstract: PURPOSE: To suppress the noise from a motor by changing the magnitude of an output signal which excites the coil of the motor in accordance with the direction of the rotation of the motor. CONSTITUTION: At the time of switching the direction of the rotation of a stepping motor 1, the phases of trapezoidal waves outputted to A- and B-phase coils 1d and 1f are made different from each other by 90 deg. and capacitors (CS) connected to terminal CA and CB are switched in accordance with the direction of the rotation by control signals S1 and S2. Namely, when the relation between the terminals CA and capacitors CS connected to the terminal is expressed by CA=C1, the capacitor connections to the terminals CA and CB are switched between CA=C2, CB=C4 when the motor is rotated clockwise and CA=C1, CB=C3 when the motor is rotated counterclockwise. The capacitance of the capacitors CSC1-CSC4 have the relations expressed by the formulae.  When the motor is rotated counterclockwise, namely, the inclination of the A-phase trapezoidal wave becomes smaller than that of the other and the A-phase torque becomes smaller than B-phase torque. When the motor is rotated clockwise, the inclination of the B-phase trapezoidal wave becomes smaller than that of the other and B-phase torque becomes smaller than A-phase torque.

IPC: F15B13/044
Filed: 1978-07-10
Abstract: PURPOSE: To provide a hydraulic servo valve, in which a first liquid chamber opend to the atmosphere and a second liquid chamber defined by resilient member are formed on the outside of a liquid chamber of control liquid, whereby it is enabled to use corrosive hydraulic liquid for operating the apparatus.  
     CONSTITUTION: Liquid in liquid chamber 20 leaks into liquid chambers 27, 39 through clearance formed between sleeve 3 and spool 4 after being trapped temporarily in liquid chambers 28, 40. Liquid introduced into the chambers 28, 40 is discharged into the atmosphere through conduit 32. On the other hand, since hydraulic liquid sticks onto the surface of spool 4, it is not possible to completely prevent leakage of hydraulic liquid into liquid chambers 27, 39 through the clearance between sleeve 3 and spool 4, when the spool 4 is driven by force motor 6. However, leakage of hydraulic liquid into the area of coil 11 can be prevented completely since liquid chambers 27, 39 and chambers 81, 83 are sealed completely from each other.
