Title: Thick film wiring material
Inventor: HOSOMI KAZUNORI
IPC: H01J29/04
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a thick film wiring material that can properly suppress the precipitation of foreign matter within an electrode. SOLUTION: Because platinum group elements are included in a thick film silver paste and alloy is formed by the reaction with silver included in it with the platinum group element paste to disperse silver into Y electrode and X electrode and then suppress reaction with the platinum constituting them, the thick film can disperse silver into an electrode and suppress the precipitation of foreign matter in burning processing of silver paste. For this reason, it hardly generates variation of electron emission efficiency or electron emission amount from an electron emission film.

Filed: 1992-12-04
Abstract: PURPOSE:To provide the matching circuit provided with an automatic adjustment means of a monolithic MIC in which the variable reactance circuit realizing an optional reactance is realized with low loss by the MIC.

Title: Nonaqueous electrolyte secondary battery
Inventor: SASAKI JO
IPC: H01M4/131
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To stop heat generation so as to prevent thermorunaway even if overcharge or an internal short-circuit occurs by covering a part or the entire part of the surface of a lithium containing metal oxide with a metal and/or carbon material mixture layer having a dissolving potential larger by a certain potential than that of lithium, and by setting the specific resistance of a positive electrode mixture layer to a specific value or less. SOLUTION: In order to restrain the interaction of a lithium containing metal oxide with a solvent of a nonaqueous electrolyte in an overcharge and an internal short circuit, a part or the entire part of the surface of the lithium containing metal oxide is covered with a metal and/or carbon material mixture layer having a dissolving potential larger by three or more volts than that of lithium. Thereby, a heat generation rate is restrained by forming an electrolyte diffusion barrier between the lithium containing metal oxide surface layer and a bulk electrolyte layer. The increase of contact resistance in conjunction with the expansion and contraction of the lithium containing metal oxide is restrained by covering it with the metal and/or carbon material mixture layer and by setting the specific resistance of a depolarizing mixture layer to 1 Ωm or less.

Title: Encoding system
Inventor: MASAMUNE KATSUNORI
IPC: G06T9/00
Filed: 1990-11-28
Abstract: PURPOSE:To shorten the signal time when document data are converted and compressed into image data by converting and compressing the margin part subsequent to a page changing code into a full-white line code directly when the document data are converted and coded into the image data. CONSTITUTION:An image data converting part 6a converts a character code in received document data into image data and writes it in a line buffer 5 and a compressing part 16 codes and compresses the data of the line buffer 5 line-sequentially. When a page changing code is detected in the document data, the image data converting part 6a ends the compression processing of a page by the compressing part 16 and notifies to a page changing code processing part 12. Thus, the page changing code processing part 12 converts the whole lines of a margin part into fixed full-white line codes.
