COMPOSITE PIEZOOELECTRIC CRYSTAL VIBRATOR

摘要

PURPOSE:To improve the reliability of a minuature vibrator unit obtained by sealing a plural number of piezo-electric vibrators in one airtight container, by identically shaping a lid body by the base body of the airtight container and by coldpressure-welding and hermetically sealing flange parts provided to the circumferences of the base body and circumferential body.
