CRYSTAL UNIT CR-(XM-28)/U

Abstract

Efforts were continued on the manufacture of crystal unit CR-(XM-28) . Attempts to obtain consistently satisfactory seals of the HC-27/U type holder were unsuccessful. A design for a new holding fixture is shown, and a commercially available sealing machine is reported. Results indicate that the unglazed base is superior to the glazed in obtaining good seals of the glass parts. A method of cleaning Kovar is reported on, as well as a satisfactory Pyroceram mixture.
