Title: Reactor core catcher
Inventor: FUKAZAWA MASANORI
IPC: G21C9/016
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To raise cooling effect with a simple structure and solid strength by providing a low melting point oxide material making eutectic by contacting debris and a high heat conductance material connected to a radiation part below a heat resistive material holding debris. SOLUTION: If an accident causing core 3 melting occurs, the lower part of reactor pressure vessel 2 breaks and molten core 3 falls in a cavity part 4 to be debris 14. The debris 14, which is constituted mainly of nuclear fuel UO2 in high temperature state, contacts a low melting point oxide material 21 of a core catcher 16. Owing to the contact to the oxide material 21, the debris oxide as the heat source of the debris 14 melts the oxide material 21 by an eutectic phenomenon to be an eutectic material together with the oxide material 21. Its melting point becomes lower than that of the debris oxide due to the effect of the oxide material 21.  Even when cooling water is injected from above to the debris 14 and cooling efficiency to the debris 14 is lowered due to crust formation during cooling, the heat conducting to the lower anti- corrosion material 20 is radiated into water in a cooling pool 22.

IPC: G11B17/26
Filed: 1987-01-30
Abstract: PURPOSE:To decrease a required time by devising a carrier mechanism that two cartridges are contained, extracted and loaded so as to reduce the vertical motion of the carrier mechanism in the replacement and quickening the replacement of cartridges. CONSTITUTION:A cartridge 1 to be replaced is fetched in one containing part 31a of the carrier mechanism 31 and the carrier mechanism 31 is moved to a position where a cartridge 1x to be replaced exists and the cartridge is extracted in the other containing part 31b of the carrier mechanism to make a room. Then the cartridge is fetched in the one containing part 31a of the carrier mechanism 31 to load the cartridge into the space to complete the replacement. Since the carrier mechanism 31 carrying the cartridge is constituted to contain, extract and load the two cartridges respectively, the vertical movement of the containing part of the carrier mechanism having required two reciprocations conventionally is reduced to one reciprocation in the replacement of the cartridge. Thus, the number of times of vertical motions becomes smaller and the cartridge replacement time is decreased thereby reducing the required loading time.

Title: Method and device for controlling motor servo type resistance welding equipment
Inventor: SONODA AKIKAZU
IPC: B23K11/11
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To obtain a device for enabling spot welding during pressurization even when there is a clearance between welded plates, by performing spot welding while the plates are pressurized at a given pressure when a clearance exists between the plates after the clearance is removed. SOLUTION: Based on a command pressurizing force, total of a setting pressurizing force required for welding and a close contact time pressurizing force when a welded plate is closely contacted, a current command value of a servo motor 41 generated at a control unit 10 is transferred to a chip elevation device 4. The chip elevation device 4 drives the servo motor 41 by the current command value, and the pressurizing force of an upper chip 2 is used as a command pressurizing force to pressurize welded plates W1 and W2, and then the current is applied between upper and lower chips 2, 3, whereby spot welding is performed. The control unit 10 monitors a rising timing of the upper chip 2, and returns the pressurizing force to a setting pressurizing force. Even if a clearance exists between the welded plates W1 and W2, the clearance is removed during welding. Since welding is performed while pressurizing the plates at a given pressurizing force, welding failures due to inefficiency of the pressurizing force do not occur.
