  • Patent number: 5372666
    Abstract: A method of manufacturing a multilayered circuit board, comprises the steps of: (a) laminating an insulating sheet on a lower layer (2) which reflects a laser light applied through the insulating sheet (4 and 6), said insulating sheet comprising a carrier film (4) and an insulating layer (6) formed on the carrier film; (b) forming via holes (8) in predetermined parts of said insulating sheet by applying a laser light thereto; (c) filling a conductive material (10) in the via holes formed in said insulating sheet; (d) forming a circuit-pattern layer (12) on said insulating layer with the via holes filled with the conductive material; (e) repeating steps (a) to (c) on an uppermost insulating sheet, and repeating steps (a) to (d) until a desired number of circuit-pattern layers are formed below said insulating sheet, in the case where the board has at least two circuit-pattern layers; and (f) firing the layers of the multilayered structure formed in the step (e) at the same time.

  • 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.

  • 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

  • Patent number: 4424091
    Abstract: A transfer sheet comprising, in laminated combination, a substrate sheet and, provided thereabove, a coloring layer of desired pattern containing a coloring agent possessing heat transferability and a resist layer of a desired pattern containing a metal compound for resist printing and a binder, the metal compound having the capability of causing the coloring layer to lose its heat transferability, either of the coloring layer and the resist layer being nearer than the other to the substrate sheet. Because of the capability of the metal compound, the resist power is very great, whereby ample resist printing effect can be obtained with only an extremely thin resist layer.
