摘要： PROBLEM TO BE SOLVED: To ensure a sufficient area on the root of a vibrating chip, make it possible to arrange a vibration detecting element these, and improve the detecting efficiency, by detecting exciting vibration for stabilization of excitation and vibration due to Coriolis force in the direction perpendicular to the exciting vibration, with the same vibration detecting element. SOLUTION: When vibrating chips 3, 4 are excited in X-axis direction by a driving circuit 131 and rotated at an angular velocity Ωaround an axis in parallel to Y-axis as the center, vibration in Z-axis direction whose amplitude is in proportion to the angular velocity Ω is generated. This vibration amplitude appears on electrodes 34, 36, 45, 48 for detection as change of charges, and is detected by a detecting circuit 132, offset-corrected by an offset correct circuit 134, and converted in a DC signal by a synchronous detection circuit 135. Then the angular velocity Ω is calculated. During the above operation, change of charges corresponding to exciting amplitude also appears on the electrodes 34, 36, 45, 48 for detection, and is detected by the detecting circuit 132, and fed-backed to a driving circuit 131 via an AGC circuit 133, thereby stabilizing the exciting amplitude.

摘要： PURPOSE:To simplify and miniaturize the constitution of a vibrating gyro. CONSTITUTION:A pair of two vibrating pieces 14, 16 are projected from a base section 12 and provided in a vibrating gyro 10 made of a light alloy such as duralumin. Only piezoelectric elements 20 for exciting the vibrating piece 14 along an X axis are mounted at the root of the vibrating piece 14 on both side faces of the vibrating piece 14. The vibrations of the vibrating piece 14 along the X axis are propagated to the vibrating piece 16, and the vibrating piece 16 is brought previously under the state of vibrations along the X axis. On the other hand, only piezoelectric elements 24 detecting the state of vibrations at a time when the vibrating piece 16 is vibrated along a Y axis are installed at the root of the vibrating piece 16 on the upper and lower surfaces of the vibrating piece 16. When the vibrating piece 16 receives Coriolis force based on rotational angular velocity omega in the periphery of a Z axis and the vibrating piece 16 is vibrated along the Y axis, the state of vibrations along the Y axis is acquired as an electric signal (AC voltage) by the piezoelectric effect of the piezoelectric elements 24.
