  • Apparatus for resistance welding of an electro-optic device housing
    Patent number: 4322599
    Abstract: A method and apparatus for welding a header to a heat sensitive cap to form an electro-optic device housing without weld flanges. A collet electrode is used to provide a radially compressive force which provides good electric and thermal contact to the wall of the heat sensitive cap and maintains the glass to metal seal under compression.
    Type: Grant
    Filed: April 28, 1980
    Date of Patent: March 30, 1982
    Assignee: RCA, Inc.

  • Coaxially mounted high frequency light detector housing
    Patent number: 4309717
    Abstract: A light detector housing in which the light detector is mounted directly on the central conductor of a coaxial transmission line and in which an electrically conducting sheet extends around the light detector forming an rf ground plane in close proximity to the detector. One or a plurality of capacitors provide a low impedance electrical connection at rf frequencies and a high impedance at zero frequency between the header of the housing and the electrically conducting sheet.
