Abstract
PURPOSE:To prevent noise produced by the impact and at the same time to reduce the power consumption by winding a hot wire round a metallic cover of a crystal vibrator and also filling an area between the vibrator and a metallic cylinder with a heat insulating and elastic substance for generation of the stray capacity. CONSTITUTION:A crystal vibrator 1 is stored in a metallic cylinder 20 in a hollow state and a hot wire 14 is wound round a metallic cover 9. Then an area between the vibrator 1 and the cylinder 20 is filled with a heat insulating and elastic substance 26 made of silicone rubber, etc. Thus the external dissipation of heat is prevented and at the same time a thin metallic wire 25 also functions to reduce the external conduction through a lead wire 6. Then the electric power supplied to the wire 14 is reduced. While the stray capacity is reduced between the vibrator 1 and the cylinder 20 and connected in series to the capacity produced between a crystal piece and the cover 9. The stray capacity is changed less by the external impacts and functions to reduce the influence on the synthetic reactance even through the capacity has change between the crystal piece and the cover 9. Thus, it is possible to prevent the noise produced by the impact and also to reduce the power consumption.
