Abstract

PURPOSE:To adjust the frequency difference independently and to drive the temperature characteristic only by frequency adjustment, by insertng a vibrating piece, where combination of bending vebration and torsional vibration is utilized, between bessels of thin plate boxes and by sealing the vibrating piece hermetically. CONSTITUTION:A vibrator 1 where a vibrator and a supporting part surrounding this vibrator and formed into one body from a crystal thin plate is inserted between plate-form vessels 3a and 3b, one or both of which are transparent, in vacuum and is sealed hermetically by solders 2a and 2b for airtight junction. By a laser beam, the weight of the node part in the torsional mode is scattered to adjust the frequency in the bending mode, and the weight of the node part in the bending mode is scattered to adjust the frequency in the torsional mode.
