Title: Molding tool
Inventor: MIYOSHI YOJI
IPC: B29C39/40
Filed: 1986-10-03
Abstract: PURPOSE:To prevent the generation of sink marks or vacuum bubbles on the surface of a molded form, which are due to a cavity, and reduce manufacturing cost, by a method wherein the inside volume of the cavity is permitted to be reduced by moving either one or both of a top force and a bottom force into the direction of mold clamping upon molding. CONSTITUTION:The height H of the projection 5 of a top force 2 for a molding tool 1 is sufficiently longer than a length, in which the height K of the cavity 4 is subtracted from the depth D of the recess 6 of a bottom force 3, when stock solution is cast into the cavity 4. Accordingly, the top force 2 as well as the bottom force 3 are permitted to be moved into the direction of mold clamping whereby the internal volume of the cavity 4 may be reduced. The internal volume of the cavity of the molding tool 1 is reduced in accordance with the shrinkage of said stock solution B by sliding the top force 2 or the bottom force 3 into the direction of mold clamping when the stock solution B is shrinked in accordance with the curing thereof. According to this method, the molding and curing of the stock solution B may be effected without generating any space in the cavity 4, having possibility to be the cause of sink marks or vacuum bubbles.

Title: Non-volatile memory control system
Inventor: SAKAI HIROSHI
IPC: G06F9/445
Filed: 1987-09-21
Abstract: PURPOSE:To shorten time required for the restoration of processing state by allowing an initial program loader to refer non-volatile memory defining information at the time of recognizing that the preceding end state is abnormal end, and initializing areas other than an area specified as a non-volatile memory. CONSTITUTION:The initial program loader 11 recognizes whether the preceding end state is normal end or abnormal end at the time of initial program loading IPL, and in case of abnormal end, refers the contents of non-volatile memory defining information 32, and when the non-volatile memory is defined, only the memory is not initialized. Since information stored before system down is left in the 'non-volatile memory' even when the system down or the like is generated and IPL is executed, recovery is made unnecessary or the necessity of recovery can be minimized. Thus, a recovery time at the time of system down can be shortened.

Abstract: PURPOSE:To make excellent both dimensional precision and external appearance for product, and to improve the life of die, etc., at the time of plastic working for hard workability metal materials like SUS steel by means of part former, header and wire drawing machine. CONSTITUTION:A high frequency induction heating device 10 or direct electrical heating device 20 is arranged in front of a header 1, heating SUS304 steel to the prescribed temp. and forging bolt parts. Both dimensional precision and external appearance are good in the heating temp. range of 80-250 deg.C, rather defective for external appearance at 300C, defective for external appearance at 400 deg.C. On the other hand, dimensional precision at 50 deg.C becomes defective. In the case of over 80 deg.C of heating temp. the die life is improved more than double as compared to that of cold working. In the case of high frequency induction heating and direct electrical heating, use of a high frequency electric current under 300kHz prevents local heating of surface, obtaining good external appearance.
