Patent number: 6397676Abstract: A driving signal is provided to six electrodes (driving electrodes) on one of the surfaces of each of three vibration legs of a three-pronged tuning-fork-type piezoelectric oscillator. Two output electrodes from among six electrodes (output electrodes) on the other surface thereof are connected to two current-to-voltage conversion devices, respectively. Since the two output electrodes are imaginarily short-circuited by the current-to-voltage conversion devices, there is no need to provide a ground electrode between the output electrodes. This makes it possible to simplify an electrode manufacturing process.Type: GrantFiled: May 9, 2000Date of Patent: June 4, 2002Assignee: Alps Electric Co., Ltd.Inventors: Yasuichi Ono, Kazuo Hasegawa, Daisuke Takai

Patent number: 6288474Abstract: A pair of electrodes are formed on the front surface and the rear surface of each vibrator in a longitudinal direction, and dielectric polarization is performed in the direction from the front surface to the rear surface. When I/V converters constituted by operational amplifiers are connected to electrodes of the middle vibrator, the detection electrodes can be grounded to a reference potential Vref through the imaginary short circuits of the I/V converters, so that a gyroscope can be vibrated without a conventional ground electrode. Therefore, the number of electrodes of the vibrators can be reduced, and an interval size between the drive electrodes or between the detection electrodes can be assured. For this reason, sufficient dielectric polarization can be performed when a high voltage is applied.Type: GrantFiled: May 25, 2000Date of Patent: September 11, 2001Assignee: Alps Electric Co., Ltd.Inventors: Yasuichi Ono, Kazuo Hasegawa, Daisuke Takai
