Inventor: INAGAKI MASANAGA
IPC: H01H85/02
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To stably fuse it by an abnormal current, restrain sensitivity to a rush current, and eliminate a fusing action by laying and forming a heating conductor film heated by abnormal current input and a fusible conductor film fused by heating of the heating conductor film at a melting point lower than this, on an insulating substrate. SOLUTION: Terminal electrodes are arranged on both ends of a cermaic substrate 1 where a glass glaze layer 2 is formed on a main surface, and a heating conductor film 3 using tungsten, molybdenum, silver or the like independently or using a high melting point metallic material of its alloy on the glass glaze layer 2 and a fusible conductor film 4 of a metallic material having a melting point lower than this, are connected in series to each other, and are laid. Selection and a shape of these materials are decided by fuse rating by considering heat conductivity of the glass glaze layer 2.  For example, the shape is set so that it does not reach a melting point or more even if it is transmitted to the fusible conductor film 4 by heating of the heating conductor film 3 in a rush current not more than a rated current, and that the fusible conductor film 4 is reliably fused by being transmitted to the fusible conductor film 4 when the heating conductor film 3 is heated in a rated current.

Title: Generation system for conditional instruction source program
Inventor: TAJI EIJI
IPC: G06F9/44
Filed: 1987-12-16
Abstract: PURPOSE:To simplify the source program generation of a conditional instruction by enabling a precompiler to compile an instruction without recognizing whether the instruction in the course of compiling belongs to any IF statement or not. CONSTITUTION:A branch instruction source 31a to be generated by a branch instruction generating means 22a designates the branch destination of a program by a label. An executable instruction source 31b to be generated by an executable instruction generating means 22b executes the instruction contents of the conditional instruction of this label. The IF instruction, i.e., the source program of the conditional performs only the distribution of processing. Since the generation of the actual instruction is realized outside the IF instruction, the precompiler 20 need not recognize any IF instruction the instruction in the course of compiling belongs to, and accordingly, the source program of the conditional instruction can be very easily generated.
