Title: Support structure for vibrator
Inventor: TERAJIMA KOKICHI
IPC: G01C19/56
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To enhance the detecting sensitivity of the angular velocity by coupling a vibrator to a support leg via a buffer material disposed in the surface not parallel to both the Y-X plane and X-Y plane at the position corresponding to the node of the vibrator. SOLUTION: Four buffer materials 2 are connected to the sides of the vibrator 1 at the positions corresponding to the nodes of the sides at an interval of 90 degrees in the circumferential direction, and the gaps between the adjacent materials 2 are disposed in Y-axis and X-axis directions. Thus, the vibrator 1 mounted with the materials 2 is coupled to the support leg 5. The materials 2 follow the bending vibration in the Y-axis of the vibrator 1 and the bending vibration in the X-axis direction of Coriolis force with large twist deformation. The transmission of the bending motions of the respective directions of the vibrator 1 to the leg 5 is effectively stopped, the restriction for the bending motion is sufficiently reduced, the vibrating attitude is stabilized, thereby making it possible to enhance the detecting sensitivity of the angular velocity.

Abstract: PROBLEM TO BE SOLVED: To suppress the jitter of a detection signal and control the tracking accurately by a method wherein the axis of a light beam entering a light converging means is so inclined as to cancel the astigmatism given to the light beam. SOLUTION: A light beam emitted from a semiconductor laser device 11 is applied to a polarization beam splitter 13 through a grating 12.
