摘要： A tuning-fork type vibration gyro enables to suppress pyroelectric noise caused by temperature change and to obtain sensor output having high signal-to-noise ratio. The tuning-fork type vibration gyro includes a tuning-fork type vibration body having two arms mutually disposed in parallel and a base for commonly supporting one end of the each arm, wherein a longitudinal direction of the two arms is defined as a z-axis and a perpendicular direction thereto is defined as an x-axis; driving electrodes respectively formed on the two arms for generating vibration of the two arms in a direction parallel to the x-axis; detecting electrodes respectively formed on the two arms for detecting electromotive force generated when the tuning-fork type vibration body is rotated around the z-axis; and dummy electrodes formed on the two arms in respective areas different from the driving electrodes and the detecting electrodes.

摘要： In a piezoelectric gyro, an amplifier 42 receives and amplifies a detected signal from detecting electrodes 19 through 26, and a bandpass filter 43 extracts only a detection-side resonant frequency component from the amplified signal. The extracted resonant frequency component is phase-shifted by a phase-shifting circuit 44, and the resultant signal is passed through a limiting resistor 45 to prepare a constant-current drive signal, and the drive signal is inputted to drive electrodes 11 through 18. As a result, the piezoelectric gyro oscillates self-excitedly at the detection-side resonant frequency. The present invention provides a piezoelectric gyro capable of maintaining a high sensitivity with respect to a change in temperature by improving detection sensitivity.

At least the longitudinal side portions of said vibrating element are coated with a surface active agent.

摘要： In a tuning fork type vibration element provided in a tuning fork type vibration gyro, the sum of inertial moments of a base to an inertial moment of two arms is 1.0 or larger. The inertial moment of the two arms is obtained by multiplying the square of a rotation radius, which is a distance from a center axis of torsional vibration as a center position between the two arms to a center of gravity of the two arms with a mass of the two arms, and the inertial moment of the base is obtained by multiplying the square of the rotation radius from the center axis of the same torsional vibration.
