20110274229 | REACTOR BOTTOM REPAIRING METHOD - A heating laser beam is emitted to a cracked portion to remove moisture from the cracked portion, and subsequently, a welding laser beam is emitted to the cracked portion to heat and melt the cracked portion. The heating laser beam and the welding laser beam are emitted to an entire surface of the cylindrical body inside the reactor such as a stub tube penetrating through and fixed to a reactor bottom portion and a crack of the welded portion between the cylindrical body and the reactor bottom portion to thereby prevent a new crack from occurring and reactor water from leaking. | 11-10-2011 |

20110266790 | FLUID COUPLING - The fluid coupling includes and houses, in a plug and a socket: valves; springs that bias the valves so as to bring the valves into pressure contact with valve seats; and spring holders which position and hold the springs. When the plug is inserted into the socket, the valves abut against each other and are retreated, and flow paths in the plug and the socket are connected to each other. Each of the valves includes: a largest diameter portion that abuts against an inner circumferential surface of the plug or the socket and positions the valve in an axial direction thereof; and inclined surfaces reduced in diameter into a conic shape from the largest diameter portion toward both sides in the axial direction. | 11-03-2011 |
