Title: Production of foamed resin molded product and molding die assembly
Inventor: ONISHI KAZUSHIGE
IPC: B29C45/56
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To enhance the dimensional accuracy through reducing the degree of beveling of a corner part by preventing the volume of the peripheral part of a cavity from being increased with the help of a pressing member. SOLUTION: A fixed half 1 and a movable half 2 of a mold are clamped in such a state that pressing members 3 provided in the fixed half 1 are brought into contact under pressure with the peripheral part of a cavity 2a in the movable half 2 with the assistance of urging means 4. Further, a molten resin containing a foaming agent is injected into the cavity 2a whose internal foaming suppression pressure is retained. Thus a skin layer is first molded and the internal volume of the cavity 2a excepting the peripheral part of the cavity 2a is expanded by moving the movable half 2 backward together with the pressing members 3, and the internal pressure of the cavity 2a is lowered to a level which enables the molten resin to foam, so that the foaming of the molten resin in the skin layer is achieved.  Since the peripheral part of the cavity 2a is not influenced by the expansion of the internal volume, it is possible to obtain foamed resin molded products with corner parts not beveled.

IPC: B60K11/04
Filed: 1986-05-06
Abstract: PURPOSE:To prevent the occurrence of overcool during cold season, by a method wherein a lower valve is attached to the temperature-sensitive cylinder, and the lower valve is forced into contact with a lower valve seat part. CONSTITUTION:A lower valve 2 is attached to a temperature-sensitive cylinder 1 of a thermostat, and a lower valve 2 is brought into contact with a lower valve seat part 3.

Abstract: PROBLEM TO BE SOLVED: To stably reduce oxygen content to a specified value and to reduce the quantity of non-metallic inclusions by refining high-Cr steel in an electric refining furnace or a ladle refining furnace, removing the slag in an initial stage in its reducing period and then, feeding the slag regulated to a specified quantity of SiO2 . SOLUTION: In a refining process of molten high-Cr steel, slag in the initial stage of a reducing period in which the quantity of SiO2 is increased with Si alloy charged to recover Cr in the reducing period in an electric furnace refining process or a ladle refining process is removed in advance. Thereafter, the slag in which the quantity of SiO2 is regulated to <=10 wt.% is newly formed and fed again for the reducing refining. The quantity of SiO2 in the slag becoming an oxygen supply source is reduced, by this way, the quantity of dissolved oxygen is efficiently reduced with Al deoxidation and high-Cr steel ingot of <=15 ppm in the oxygen content can be easily, stably and economically obtained with a high yield. At the same time, the generation of Al2 O3 , or the like, as a by-product through the deoxidation can be suppressed by suppressing the oxygen supply.

Title: Record protecting method of magnetic disk storage device
Inventor: INOUE EIICHI
IPC: G11B19/04
Filed: 1981-07-07
Abstract: PURPOSE:To prevent a failure in data recording to a magnetic disk storage device by starting normal processing after writing operation interrupted owing to a break of power supply is performed again after the power supply recovers. CONSTITUTION:When a power-supply recovery detector 14 detects power-supply recovery, a write instruction, data, a transfer starting address, etc., are set up in data format in a transfer data control word storage memory 13 and then the write instruction, etc., is sent from a central arithmetic control part 7 to a magnetic disk control part 9 through an input and output bus 12. The control part 9 interprets the instruction to read data out of a memory 13 through a memory bus 11, converts the data into byte data, and then transfers them to a magnetic disk storage device successively. Therefore, even if a power source is turned of, written data during a power break is stored in the memory 13, so once the power-supply recovery is detected, a control part 15 refers to the contents of the memory 13 and performs the writing operation during the break of power supply, thus a failure in data recording is eliminated.
