IPC: B22F1/10
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of defects such as cracks in a molded body by specifying the amts. of polyacetal resin and modified polyolefin resin and the total amt. of the resins. SOLUTION: This compsn. contains a binder contg. 10-90vol.%, in total, of 5-60vol.% polyacetal resin and 5-85vol.% modified polyolefin resin.

Title: Processor
Inventor: HASEGAWA YUTAKA
IPC: G03G15/00
Filed: 1987-11-20
Abstract: PURPOSE:To facilitate and rationalize the use of the processor except in a registered time by resetting an off-mode and setting an on mode when there is an no-mode setting indication in the off-mode, initializing a time measuring means every time an operator operates, and resetting the on-mode and setting the off-mode when the measured time of the time measuring means exceeds a specific value. CONSTITUTION:Even when the off-mode is set, the on-mode is easily set by inputting the on-mode setting indication by a processor 2c whose power supply is controlled automatically by a timer function. In this case, the storage contents of on/off mode set time, etc., are not renewed, so the on/off mode automatic control never becomes improper. Further, when the on-mode is set through the operation of an on-mode setting indicating means 1, the on-mode is reset and the off-mode is set unless the operator operates after a specific time. Consequently, the power supply is controlled automatically and rationally.

Title: Mesa discrete semiconductor device
Inventor: TAKEO KYOZO
IPC: H01L29/73
Filed: 1990-10-31
Abstract: PURPOSE:To simultaneously achieve that a breakdown strength is made high and that a saturation voltage characteristic is reduced by a method wherein regions whose thickness is different are formed on a semiconductor layer constituting a collector on the rear side of a semiconductor substrate. CONSTITUTION:Phosphorus on the order of 10<20> <to> <21>/cc is introduced into one face of an N<-> silicon semiconductor substrate 10; after that, a slumping process is executed. Thereby, an N<+> semiconductor layer 11 whose diffusion depth Xj is at about 210mum is formed selectively. Then, a phosphorus oxychloride layer 13 on the order of 10<20> <to> <21>/cc in the same manner is deposited on the revealed face of the N<-> silicon semiconductor substrate 11 surrounding the N<+> semiconductor layer 11; after that, a slumping treatment is executed for a prescribed time; an N<+> semiconductor layer 14 whose Xj is within 165mum is formed. As a result, since the Xj of the N<+> semiconductor layer 11 is different from that of the N<+> semiconductor layer 14 as described in the claims, it becomes a region whose thickness is different and it is of a two-step structure. The impurity concentration of the N<-> silicon semiconductor substrate 10 is different from that of the N<+> semiconductor layer 11. Thereby, it is possible to simultaneously achieve that a breakdown strength is made high and that a saturation voltage characteristic is reduced.

IPC: G06F9/38
Filed: 1985-12-26
Abstract: PURPOSE:To attain the control of priority for both an instruction code access and an operand data access by deciding the operation for priority by the comparison output of the instruction count value. CONSTITUTION:A fetch counter 5 counts the number of instruction codes read from a time point when the control for execution of instructions is shifted by the factors including the execution of a branch instruction, the occurrence of an interruption, etc. Then a counter detector 8 checks whether or not the count output of the counter 5 reaches >=1 designated values. An arbiter 11 decides the priority based on the output of the detector 8 for the input request signal sent from a fetch controller 9 for an instruction buffer 1 as well as the operand request signal received from a decoder or an instruction executing part. Then the result of said decision is sent back as an input or operand permission signal. At the same time, the control signal and the trigger signal are produced for a data bus switch 12 and a bus cycle controller 13 respectively.
