Title: Semiconductor capacitance type multi-spindle acceleration sensor
Inventor: HOSOYA KATSUMI
IPC: G01P15/18
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor capacitance type multi-spindle acceleration sensor that can reduce the change in characteristic due to a temperature change. SOLUTION: A silicon substrate 3 where a movable electrode 6, a beam part 10, and a frame 3a are formed is arranged between first and second fixing substrates 1 and 2 and each substrate is joined. The movable electrode is connected in one piece via one edge 10a of the beam part. The beam part is separated from the frame, the other edge 10b of the beam part is formed thickly, and the other edge is joined to the first fixing substrate. Therefore, frame distortion being generated due to the difference in a temperature expansion rate with the first fixing substrate is not transferred to the beam part. Further, since the area of the other edge of the beam in contact with the first fixing substrate is small, the beam part cannot be generated greatly at the beam part.  Therefore, the change in the tension of the beam part is reduced and the capacitance between the movable electrode and each fixing electrode does not change greatly due to a temperature change.

IPC: G02B1/115
Filed: 1988-03-10
Abstract: PURPOSE:To create a reflecting body reflecting artificially colored light other than gold color in place of conventional gold reflected color by eliminating white reflected color completely.
