Definitions

  • -It is, moreover, an object of the present invention to provide a miniaturized trimmer potentiometer which is, in spite of its unusual capabilities, formed of parts which are inherently inexpensive, and which may be easily and quickly assembled and sealed with a final epoxy potting step.
  • sonic vibration raises the temperature of the thermoplastic material so that a portion is pressed ahead of the ridges in the form of ripples 96.
