Abstract
PURPOSE:To prevent the local deterioration of an interface part by using a sealing/ junction part as a mixture part of both elements to be connected. CONSTITUTION:Container 10 is made with glass; chromium layer 12 is vapor-deposited on a sealing part to a thickness of approximate 500Angstrom , and silver layer 13 on it to a thickness of approximate 1mu. Then, solder layer 14 is formed to approximate 30mu. The junction part of each layer has a mixture region of the both. On cap 11, nickel layer 15 and silver layer 16 are vapor-deposited to thicknesses of approximate 1mu and 3mu respectively. A junction between the both has a mixture part of both metals formed. Container 10 with crystal vibrator 17 installed is covered with cap 11. Thus, each junction part has the metal mixture part formed; Cr25, Co31, Ni29, Cu, etc., serve as a binder, and Ag26, Pb28, Cd, etc., as a soft metal advantageous to junction, thereby reinforcing the sealing of it.
