Abstract:

Efforts concern establishment of a facility for the manufacture of crystal-units CR-XM28U utilizing the HC-27U all glass holder. Comparisons of results achieved using goldplated electrodes with those achieved using aluminum, are made. The same improvement in control of frequency change is noted when the film is annealed prior to sealing in glass. Final details of the limited production equipment were worked out and the equipment is described. A method for determining dimensions of glass units is reported. Author
