Title: Vibration gyro
Inventor: AOTSU SHINICHI
IPC: G01C19/56
Filed: 1991-10-31
Abstract: PURPOSE:To detect a rotational angular velocity with a prescribed precision at all times by removing the effect of an external magnetic field by disposing a magnetic shield member at a position in proximity to a vibrator. CONSTITUTION:A vibrator 3 is constructed by sticking a piezoelectric element 2 having a driving function and a detecting function on two adjacent lateral surfaces of a vibrating body 1 located on the opposite sides of the ridgeline of the body, and this vibrator 3 is supported on a base 5 by wires 4a and 4b for support at a position corresponding to a nodal point of a bending motion or in the vicinity of the position. The whole of these parts are held in a magnetic shield case 7 and positioned and fixed therein. When a vibration gyro 8 constructed in this way is installed on a fitting member 9 so that the axial line of the vibrating body is directed in the vertical direction, a magnetic flux is concentrated on the magnetic shield case 7 and passes therethrough even when a magnetic member 10 is present near the gyro. Therefore the vibrator 3 is not affected by an external magnetic field and can detect a rotational angular velocity stably with a prescribed precision at all times.
