Title: Vibrational gyro
Inventor: KIYONO YUICHI
IPC: G01C19/5607
Filed: 1993-04-30
Abstract: PURPOSE:To effectively cancel the Null signal of a vibrational gyro. CONSTITUTION:Piezoelectric elements 14 and 15 for detection are respectively stuck to the front and rear surfaces of the coupling section 3 of four arms 2 of a vibrator 1. The elements 14 and 15 respectively have interdigital electrodes 16 and 17. The interdigital electrodes 16 and 17 of the elements 14 and 15 have the same electrode pattern on the front side of the vibrator 1. The outputs fc of the elements 14 and 15 when a Coriolis force acts become opposite in phase between the front and rear sides. Therefore, a Coriolis output can be obtained from the differential outputs of the front-and rear-side elements 14 and 15. On the other hand, the Null signals of the elements 14 and 15 become opposite in phase between the front and rear sides. Therefore, the Null signals can be effectively canceled by the differential outputs of the elements 14 and 15. In addition, in-phase noise generated in a signal processing circuit can be also canceled by the differential output.
