Abstract

PURPOSE: To prevent breaking due to shock and vibration and simultaneously to make restoration of the frequency earlier, by supporting a small tuning fork type piezo electric vibrator by use of jointing material such as glass and solder of low melting point between two transparant plates of the vibrator and by maiking the clearance of the transparent plate and the vibrating plate less than 0,2 mm.
