  • Method of manufacturing thermal printer head
    Patent number: 5032158
    Abstract: A method of manufacturing a thermal printer head on a substrate having a heat accumulating layer on a surface thereof, a dot-like heat generating resistor group arranged in a straight line on said surface of said heat accumulating layer, and an electrode group for supplying power to said heat generating resistor group. The heat accumulating layer is formed by the sequential steps of:(1) forming a slip, which contains, as major component, an inorganic powder material for constituting said heat accumulating layer and an organic binder into a green sheet;(2) cutting the green sheet into the shape of heat accumulating layer;(3) laminating the cut green sheet to a predetermined position of the substrate; and(4) firing the green sheet.

    Inventors: Sadanobu Kawasaki, Hideaki Kuno, Donald W. Kuty
  • Method of manufacturing gas discharge display device
    Patent number: 5011391
    Abstract: A method of manufacturing a gas discharge display device comprising a pair of panel substrates arranged to oppose each other at a predetermined gap, at least one of said pair of panel substrates having on a surface thereof a plurality of electrodes which form discharge light-emitting display sections and an insulating barrier for defining the discharge light-emitting display section, the pair of panel substrates being encapsulated by an encapsulating member, characterized in that the method of forming the insulating barrier comprises the sequential steps of:(1) forming a slip, which contains, as major component, finely divided electrically insulating solids which form a major constituent of the insulating barrier, and an organic binder, into a green sheet;(2) processing the green sheet by forming holes in the green sheet in an array corresponding to discharge areas such that the green sheet remaining between the holes defines the insulating barrier;(3) laminating the processed green sheet to a predetermined p
