专利汇可以提供Piezoelectric ceramic vibrator专利检索,专利查询,专利分析的服务。并且PURPOSE:To prevent deterioration of quality due to thermal stress by forming a metallic cap of a piezoelectric element of the piezoelectric ceramic vibrator used for generating a clock signal of a microprocessor at the state from the expansion into welding before the cap is fitted externally to a cylinder. CONSTITUTION:A cap forming metallic plate cut into a prescribed shape is made up of a plate 11 formed into a cylinder, circular side parts 12 provided side by side, and a lead terminal 13 provided a side the side plate 12. The plate 11 is formed cylindrically before it is fitted externally to a cylinder 14 made of an alumina ceramic a resin forming so as to form a cap 15 with a lead terminal, and it is pressed externally to both openings of the cylinder 14 at the inside of which the piezoelectric element is inserted. A conductive adhesives is coated at both the openings of the cylinder 14 in advance before cap external fit. The plate 11 and the side plate 12 are welded while the cap 15 is fitted externally to the cylinder 14.,下面是Piezoelectric ceramic vibrator专利的具体信息内容。
