静電浮上型ジャイロ装置

Electrostatic floating type gyroscope system

Abstract

PROBLEM TO BE SOLVED: To substantially preclude a displacement detecting signal from being affected even when generating a control voltage by pulse width modulation. SOLUTION: Outputs of the control voltages A, B are executed by the pulse width modulation 41, as to a control circuit 40, displacement detecting electrodes impressed with no control voltage are allocated to both impression side electrodes 22 impressed with an impression signal C from an impression signal generating circuit 31, and detecting side electrodes 23 used for detecting detection signals D, E, as to the plurality electrodes 21-25 formed in a gyro case 20, and the impression side electrodes 22 or the detecting side electrodes 23 are arranged dispersedly to be adjacent to an electrostatic supporting electrodes 24.

【課題】制御電圧の生成をパルス幅変調で行っても、その影響が変位検出用信号にはほとんど及ばないようにする。 【解決手段】制御回路40については、制御電圧A,Bの出力をパルス幅変調(41)にて行うようにし、ジャイロケース20に形成された複数電極21〜25については、印加信号発生回路31から印加信号Cを印加される印加側電極22にも、検出信号D,Eの検出に用いられる検出側電極23にも、制御電圧の印加されない変位検出用電極を割り当て、印加側電極22又は検出側電極23を静電支持用電極24に近接させて分散配置する。 【選択図】 図1
