摘要： The shape of drive electrodes and/or the shape of detection electrodes of a tuning fork type vibration gyro are made asymmetrical between the inside and outside of the arm, and between the surface and reverse face of the arm, to reduce the abnormal vibration and leaking output. The drive electrodes to be provided on the inside parts of the surface and reverse face of the first arm are formed smaller than the drive electrodes to be provided on the outside parts of the surface and reverse face thereof. The length of the detection electrode to be provided on the outside lateral face of the second arm is formed short. The drive electrodes to be provided on the surface and reverse face of the first arm are extended to the base side from the boundary position between the first arm and the base, and the detection electrodes to be provided on the surface and reverse face of the second arm are extended to the base side from the boundary position between the second arm and the base.

摘要： A resonator device having an insulating substrate, a strip-shaped vibrating element which is mounted on said insulating substrate and is provided with driving electrodes formed on the main opposing surfaces of a piezoelectric substrate, and terminal electrodes which are provided on said insulating substrate so as to be electrically connected with said driving electrodes and to which driving signals are applied by an external signal source. At least the longitudinal side portions of said vibrating element are coated with a surface active agent. With such a constitution, fluctuations in resonant resistance which are due to the excitation level can be suppressed, thereby contributing to the stable operation of the device, reducing the number of producing steps, and raising the yield rate in production.
