Title:
ANGULAR VELOCITY METER
Document Type and Number:
Japanese Patent JPH02163612
Kind Code:
A
Abstract:
PURPOSE:To obtain an angular velocity which attenuates a disturbance vibration but does not attenuate an input angular velocity by providing a cylindrical case, a frame body and a disk-like diaphragm. CONSTITUTION:In a cylindrical case 11 of a cylindrical shape whose both ends are blocked, a vibration mechanism is held through a fixed beam member in the inside so that its detection axis and the center axis of the case coincide with each other. To both end faces of the case 11, disk-like diaphragms 12a, 12b formed from an elastic member are fixed through clamp plates 15a, 15b so that its center coincides with the detection axis of the vibration mechanism. A frame body 13 fixed to an object to be measured has a cylindrical part 13a whose diameter is larger than the outside diameter of the case 11, and the case 11 is contained in the cylindrical part 13a. According to this constitution, other vibration than the detection axis direction of the vibration mechanism is given to the frame body 13, the diaphragm 12 attenuates it, and does not attenuate only the vibration around the detection axis but propagates it to the vibration mechanism, mechanism, therefore, the influence by which other component than an input angular velocity being an object to be detected is mixed into a vibrating state is reeuced.
