摘要： A cleaning apparatus is generally composed of a suction unit provided with a suction source, a suction nozzle equipped with a suction port adapted to suck dust or like from a surface to be cleaned, a suction hose connected at one end to the suction nozzle and connected at another end to the suction unit, a low-center-of-gravity support member provided for the suction hose so as to serve as a fulcrum when the suction hose is bent and deformed, a wire member supported at a distal end by the suction nozzle and arranged along the suction hose, and a control unit used to bend and deform the suction hose by manipulating the wire member with the low-center-of-gravity support member serving as a fulcrum. This cleaning apparatus is specifically usable for a bottom surface of a reactor pressure vessel.

摘要： According to one embodiment, a laser welding apparatus has a laser irradiation head that is arranged in an outer frame and is divided inside into a light source side and an irradiation side by a partitioning member. The apparatus also has a gas jet nozzle that is formed so as to irradiate a portion to be welded with the laser light and jet the inert gas to the portion to be welded; and a welding wire feed pipe that sequentially feeds a welding wire. The apparatus also has a welding wire contact mechanism that includes a measuring means for measuring a distance between the extremity of the irradiation side and the extremity of the welding wire, and is formed so that the extremity of the welding wire is brought into contact with and pressed against the portion to be welded by an elastic member.
