Patent number: 5032158Abstract: 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.Type: GrantFiled: October 31, 1990Date of Patent: July 16, 1991Assignee: E. I. Du Pont de Nemours and CompanyInventors: Sadanobu Kawasaki, Hideaki Kuno, Donald W. Kuty

Patent number: 4424091Abstract: 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.Type: GrantFiled: January 28, 1981Date of Patent: January 3, 1984Assignee: Dai Nippon Insatsu Kabushiki KaishaInventors: Shogo Mizuno, Takao Suzuki, Sadanobu Kawasaki, Hideichiro Takeda
