Title: Tortional vibration restriction control method
Inventor: FUJIKAWA ATSUSHI
IPC: H02P25/098
Filed: 1991-12-13
Abstract: PURPOSE:To improve tortional vibration-proofing transient characteristics by estimating a tortional velocity difference from the vibration component of tortional torque to a feedback velocity control system of a tortional system. CONSTITUTION:A velocity feedback control system of a tortional shaft system comprises a velocity P (I) control section 1, inverter section (torque coefficient generator) 2, a motor section 3 ignoring the damping of the motor, a tortional shaft section 4 ignoring the damping of the shaft, and a load section 5 ignoring the damping of a load. By applying the tortional torque (value detected by a torque meter) Ttheta of this system to the inverse function ratio section 6 of the tortional shaft ignoring the damping of the shaft, the velocity difference of the load of the motor of the tortional system can be estimated. This estimated value is added to the velocity of the motor and the result is used as velocity feedback value. Also, the tortional torque Ttheta is directly added to the torque command for compensating disturbance torque.

Title: Dual-source output amplifier
Inventor: ENRIKE RODORIGESUUKABASOSU
IPC: H04N3/18
Filed: 1989-12-22
Abstract: PURPOSE: To reduce the power consumption of an amplifier by using a low voltage power when a necessary output voltage is relatively low and using a high voltage power when the output voltage reeds a driving voltage high in the rapid change of output current. CONSTITUTION: A sensing circuit 22 detects an output voltage for driving a convergence coil 24. If the output voltage exceeds the prescribed value, the sensing circuit makes one of two voltage adjusters 11 and 13 not operate, and combines a larger supply voltage with an output stage. The operation of a low voltage mode arises when the output signal is within the range of a 1st voltage level, and the operation of a high voltage mode arises the output signal is within the range of a 2nd voltage level larger than the voltage level of the 1st range. Circuit components 18 and 20 are separated from the lower voltage source from the higher voltage source when the higher voltage source is connected to the output stage. Thus, the power consumption of the amplifier reduces.

IPC: H02N2/00
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To make an accurate and fine drive control available from a start-up by setting a drive frequency of a vibrating actuator for a start-up, based on the impedance measured by inputting AC voltage or pulse voltage at which the vibrating actuator does not operate, while the vibrating actuator is not driving. SOLUTION: In an internal memory of a controller 21, the fluctuation of the impedance of a vibrating actuator 10 is stored depending on the temperature. While the vibrating actuator is not driving, an oscillator 22 is controlled so that a frequency sufficiently far away from the preliminarily measured resonance frequency of the vibrating actuator may be applied to the vibrating actuator. At that time, the controller 21 calculates the impedance, based on the driving voltage and the drive current measured by an ammeter 26 and then finds a drive frequency of the vibrating actuator from the calculated impedance.
