Abstract

PURPOSE: To complete an air-tight sealing, and facilitate a work of electrical connection, by making the sealing temperature of a metal, for sealing a metal rod inserted through the insulator ring, higher than that for sealing the insulator ring to the peripheral case.
CONSTITUTION: To the opening end of a peripheral case 1 is air-tightly sealed a face plate 2 through an activated alloy 22, 24 and an insulator ring 23. The insulator ring 23 is constructed by ceramic, and a permeable hole 25 is drilled in a direction intersecting perpendicularly to the tube axis. Through the permeable hole 25 is inserted a metallic rod 26 and electrically connected to the bus of a color separation filter 11 through a spring 27. Another end of the metallic rod 26 is air-tightly sealed by an activated alloy 28 consisting of, for instance, Pb, Sn, Zn, Cd, Sb. A sealing temperature of the alloy 28 is made higher than that of the activated alloy 22, 24 consisting of, for instance, PB, Sn, Zn, Cd, Sb, In, Bi. In this way, a lead- out of the internal signal to outside is made with ease, simultaneously an air-tight sealing can be completed.
