Title:
GYROSCOPIC DEVICE
Document Type and Number:
Japanese Patent JP3181368
Kind Code:
B2
Abstract:

PURPOSE: To detect input angular velocity on the basis of the change of the electrostatic capacity obtained from the detection electrodes corresponding to the respective inclined planes of a gyroscopic device, especially, a vibrator having a triangular cross section.
CONSTITUTION: In a gyroscopic device, the vibrator 1 supported on a support member 2 in a freely vibratory state and having a triangular cross section is used. The detection electrodes 3, 4 corresponding to the vibrator 1 are constituted of a silicon substrate along with the vibrator and input angular velocity is detected on the basis of the change of electrostatic capacity.
