Abstract

1495355 Piezo-electric resonator DAINI SEIKOSHA KK 8 April 1975 [9 April 1974 23 April 1974] 14430/75 Heading H1E To improve shock resistance a piezo-electric resonator is supported at one end by springs on a terminal structure and connected by the springs to terminals glass sealed through the structure. Quartz tuning fork watch resonator, hermetically sealed in metal housing 1 in which terminals 2b, 2c are glass sealed through outer member 2a, is supported by bronze or Be-Cu J-shaped springs soldered or welded to metal plates 2d, 2e mounted on the terminals, electrical connection also being made by the springs.
