Title: Production of thermally conductive base plate
Inventor: ITSUDO YOSHIKO
IPC: C04B37/02
Filed: 1990-09-28
Abstract: PURPOSE:To join a metallic member to an AlN-based base body at high joining strength by forming an oxidative film on the AlN-based base body by a sol-gel method in the case of producing a thermally conductive base plate wherein an aluminum nitride-based sintered body is used. CONSTITUTION:An AlN-based base body is coated with a soln. formed of metallic alkoxide and an organic solvent. The coated film is allowed to gelatinize by a proper method. An oxidative film is formed by heat-treating the film allowed to gelatinize. In order to enhance wettability of the liquid phase of eutectic alloy which is formed of the metallic member to be joined together with oxygen, this oxidative film is formed in a preceding state of a joining stage. Thickness thereof is preferably regulated to <=5mum because the thermal expansion coefficient ordinarily differs from AlN. Then, this oxidative film is brought into contact with the metallic member and heated to join metal to the AlN-based base body via the oxidative film. Metal is joined to the AlN- based base body at high joining strength by this method. The thermally conductive base plate is obtained which is free from blistering, warpage, waviness and peeling.

IPC: B41J2/485
Filed: 1993-10-18
Abstract: PURPOSE:To provide a printing atmosphere according to a wide need by a method wherein a specific image processing is carried out, and printing is carried out by using a specific recording material as a recording medium based on the image processed output data. CONSTITUTION:A CPU 3 judges whether a content of printing information is an outline font or not (1). When it is YES, scaling (rasterize) of the outline is carried out, and only an outline letter indicating a contour of the font is printed (2). The process is ended. Besides, when the information is printing information excepting the outline font by judgement of the step (1), for example, it is a bit map font, a process such as ordinary bit map expansion or the like is executed and a solid letter shown in ordinary printing is printed (3) to end the process. By this method, a consumption of a developer or an ink agent can be reduced, and besides rasterize processing time can be also decreased.
