<p>An acceleration detection type gyro device electrostatically supported and arranged to actively make the displacement of a gyro rotor zero, which comprises a gyro case, a gyro rotor supported in a noncontact manner in the gyro case by electrostatic support force, an electrostatic support electrode for producing the electrostatic support force, a rotor drive system for rotating the gyro rotor at high speed around a spin axis, a displacement detecting system for detecting the displacement of the gyro rotor, and a restraint control system having a feedback loop for so correcting a control voltage applied to the electrostatic support electrode as to make the displacement of the gyro rotor zero, wherein the gyro rotor is annulus and the electrostatic support electrode is arranged to surround the gyro rotor.</p> |
