Abstract

PURPOSE:To reduce a secular change by lessening the displacement of the base of a vibrator by fitting a weight to the base. CONSTITUTION:With regard to a vibrator in any shape and any mode, the virtual vibrating of it without support results it that its center of gravity is stationary. Therefore, supporting the center of gravity makes it possible to maintain a high Q value without any loss of vibration energy. For the purpose, weight 12 is added to the base of vibrator 11. The part where weight 12 is added should be close to position 13 of the center of gravity and the displacement of this part is small, which is adequate to support vibrator 11. Since the vibrator can be supported with the displacement of the base part reduced, its vibration is stabilized and the secular change can reduced.
