Title: Starting device for ultrasonic motor
Inventor: YOSHIOKA SHIGEKI
IPC: H02N2/00
Filed: 1989-06-16
Abstract: PURPOSE:To prevent the generation of uncomfortable abnormal sound upon starting an ultrasonic motor by a method wherein the frequency of a voltage, impressed on a piezoelectric body, is set so as to be higher than a predetermined driving frequency and, then, the frequency of the voltage is reduced sequentially. CONSTITUTION:A microcomputer 3 reads a data from an A/D converter 25, determines a driving frequency for an ultrasonic motor in accordance with the value of the read data, outputs a data in reference to the driving frequency to a D/A converter 5 and drives the ultrasonic motor. The frequency of a voltage, impressed on a piezoelectric body upon starting the motor, is set so as to be higher than predetermined driving frequency and resonance frequency but so as to be lower than a subsequent resonance frequency and the frequency of the voltage, outputted thereafter, is reduced sequentially. According to this method, a coincidence between the frequency of the voltage, impressed on the piezoelectric body upon starting the ultrasonic motor, and the resonance frequency may be avoided and the generation of uncomfortable abnormal sound upon starting the same may be prevented.

Title: Driving method for ferroelectric liquid crystal device
Inventor: HIGA MASAKATSU
IPC: G02F1/133
Filed: 1993-06-23
Abstract: PURPOSE:To shorten scanning time in order to enable high-speed writing and to suppress flickering of display without deviation in electric charges over the entire part of the waveforms of one frame so as to assure stable operation by impressing at least one pulse to compensate the deviation of the electric charges generated in a selection period, in the non-selection period just before the selection period. CONSTITUTION:While -V1 is impressed in the first period t1 of the selection period which is the timing existing at the top in one frame Tf and V2 in the second period t2 to each of common electrodes C1, C2..., a voltage value Vr is impressed by disposing a reset period tr in the position just before the selection pulse of the next frame. This impression is executed by disposing the reset period tr at the final of the non-selection period just before the selection period ts and impressing the pulse voltage Vr of the polarity reverse from the polarity of the deviation in the electric charges generated in the selection period. The generation of the deviation in the electric charges within one time of the writing time is thus obviated.
