    摘要： An inclination of an inclined surface formed by working a ridge of a resonator is set to be within a predetermined angular range, whereby a leakage of vibration in the out-of-plane direction is reduced, the leakage of vibration being generated according to the detuning degree adjustment. In addition, a single laser beam is irradiated onto the ridge at an incident angle within a predetermined angular range, whereby a simple working on the inclined surface is established for the leakage vibration adjustment. A degree of the leakage vibration of the resonator is determined based on a relationship with the drift amount that is a ratio of the angular velocity change, and the inclination of the inclined surface is set to be within a predetermined angular range, thereby suppressing the drift amount.

    摘要： A vibration gyro having a high accuracy, no vibration leak, and high S/N. The width of a detection leg of a resonator used in the vibration gyro is less than ⅗ of the width of drive legs. The length of the detection leg is larger than the length of the drive legs. As a result, the distance between the detection electrodes is decreased by comparison with the conventional vibration gyro and, therefore, the detection signal is increased and S/N is raised. Furthermore, increasing the leg length brings the natural vibration frequency of out-of-plane vibration of the drive legs close to the natural vibration frequency of the detection leg, providing good coupling and reducing vibration leak to the support section. As a result, Q is increased and S/N is accordingly further increased.

    摘要： A vibration gyro has a vibrator composed of three tines (first, second, and third tines) which are aligned in a single line at prescribed intervals in one direction on a base and extend in a direction perpendicular to an aligning direction. A central second tine and an adjacent first tine on a left are driven by oscillator. Further, Coriolis force generated on the second tine and the third tine on a right is detected by a detector. In this vibration gyro, the dimensions of the parts are determined so as to cause the third tine to substantially stand still when the first and second tines are driven by the oscillator.

    摘要： At the frequency of natural vibration with which the driving tines and detection tine of a piezoelectric vibrator resonate, the vibration directions of natural vibrations and the frequency difference between the resonance frequencies are set to reduce the leakage of vibration from the driving tines to the detection tine for suppressing the leakage vibration of the piezoelectric vibrator. In the piezoelectric vibrator, the vibration direction of the driving tines is made orthogonal to the vibration direction of the detection tine, or the frequency difference between the resonance frequency of the driving tines in the in-plane direction and the resonance frequency of the driving tines in the out-of-plane direction is increased sufficiently to suppress the growth of the leakage vibration. This configuration makes the piezoelectric vibrator compact and reduces leakage vibrations.
