  • Patent number: 5062891
    Abstract: Metallization, applied by the thick film screening technique, utilized herein has glass-ceramic bonding agents designed to promote adhesion yet maintain the desired electrical properties and post-processing characteristics.
    Type: Grant
    Filed: August 13, 1987
    Date of Patent: November 5, 1991
    Assignee: Ceramics Process Systems Corporation
    Inventors: William C. Gruber, Eric A. Barringer
  • Patent number: 4861646
    Abstract: Glass-ceramic packages for integrated circuits containing multi-layer, interconnected thick film wiring patterns are obtained by co-sintering a glass-ceramic composite and copper, silver, palladium, gold, based conductors at temperatures not exceeding about 1000.degree. C. The dielectric systems include composites of borosilicate glasses and crystalline fillers which are fabricated by either mixing glass frit and the filler or by a sol-gel coating process. The package is fabricated using a tape specifically designed for clean binder burnout in a reducing atmosphere at low temperatures and also for superior mechanical and thermal properties. Metallization, applied by the thick film screening technique, utilized herein has glass-ceramic bonding agents designed to promote adhesion yet maintain the desired electrical properties and post-processing characteristics.

  • Patent number: 4169685
    Abstract: A panel of selectively-controllable indicator elements is associated with a viewable escapement scale on a typewriter and provides an indication of a set of operative tab stops stored in an electronic memory. Escapement position codes extracted from an electronic tab storage drive a logic circuit that is so connected as to modify the state of individual panel elements at corresponding escapement scale positions to indicate a tab layout. By providing, in a preferred implementation, means for accessing the presently operative (selected) set of tab codes from a memory adapted to retain plural tab sets, the operator is enabled to assess the layout of each selection visually. In such an implementation for a typewriter having two different selectable pitches, say pitches of 10 and 12 characters per inch, the panel elements are arranged to display the selected tab layout respective of pitch.
