VIBRATING-TYPE GYROSCOPE ELEMENT AND ANGULAR VELOCITY SENSOR INCLUDING SAME
A vibrating-type gyroscope element includes a fixed part, a resonator having a vibration mode of cos Nθ (N is a natural number of two or more), support parts-30, and electrodes. The electrodes are arranged in 4N orientations arranged in an outer circumferential direction of the resonator. The electr...

| description | A vibrating-type gyroscope element includes a fixed part, a resonator having a vibration mode of cos Nθ (N is a natural number of two or more), support parts-30, and electrodes. The electrodes are arranged in 4N orientations arranged in an outer circumferential direction of the resonator. The electrodes include at least one primary driving electrode-PD and at least one secondary pickoff electrode. A relationship U ≥ 1 or (S1 + S2) - 2 ≥ |S1 - S2| is satisfied, where S1 is the number of cases where a secondary pickoff electrode is clockwise adjacent to a primary driving electrode, S2 is the number of cases where a secondary pickoff electrode is anticlockwise adjacent to a primary driving electrode, and U is the number of the secondary pickoff electrodes being neither clockwise nor anticlockwise adjacent to a primary driving electrode. |
