摘要： PURPOSE:To provide a smaller inspector with excellent radiation resistance concerning a fluorescence permeation flaw inspection of a deposit weld part of a neutron flux monitoring housing at a lower part of a reactor pressure vessel. CONSTITUTION:A permeation flaw detector 5 is set right above a through hole 3b of a neutron flux monitoring housing within a reactor with a setting mechanism 6. The permeation flaw detector 5 has three types of drive mechanisms--a lift shaft drive mechanism 14, an encircling shaft drive mechanism 15 and a radial shaft drive mechanism 16--and a flaw liquidcoating mechanism 9 is arranged at the tips of the drive mechanisms. A camera mechanism 10 having a supermini CCD camera is held with a camera mounting mechanism 11 to be inserted into the reactor through the through hole 3b from a pedestal at an external lower part of a pressure vessel and mounted at the tip of the flaw liquid coating mechanism 9 by a remote control. Three types of drive mechanisms are operated and a plurality of surfaces to be inspected of a deposit weld part or the like undergoes a liquid permeation flaw detection to observe the results of the flaw detection with the camera mechanism 10.

摘要： PURPOSE:To make an arm formation conformed to the work breakdown realizable and to aim at high output, high rigidity and high precision of robot power by a method wherein plural pieces of robots are provided with plural units of connecting mechanism which partially connects or separated to or from each other and these robots are connected with each other through the connecting mechanism. CONSTITUTION:A robot 1 and a robot 2 travel on a rail 4 separately, rotating respective articulations, and their hands are positioned at the optical location, thereby performing various operations. In the case where such high output work as unable to be done by an independent arm is performed, the robot 1 assumes the same position as the robot 2, and it travels on the rail 4, getting nearer to the robot 2, and a synchronous connection of four connecting mechanisms 23c, 23d, 23e, 23f themselves is thus carried out. With this constitution, force to be added to an arm tip is dispersed in respective articulated axes of both these robots 1 and 2, where double high power is securable as compared with each individual case.

摘要： PURPOSE:To enable positive fitting with one attempt by clearing vector product direction force at the time of detecting reaction, then detecting the existence of axial moment corresponding only to the force applied to the direction of the fitting axis of a moving fitting part, and moving this moving fitting part in the axial moment applied direction for insertion. CONSTITUTION:The force 17 preset to press a fitting part 3 in the direction of a fitting axis 3b is applied to the moving fitting part 3, and the distortion of a moment detecting beam at this time is detected. The direction of the axial moment 19 of torque vertical to the fitting axis 3b of the recessed fitting part 3 is identified from the detected distortion, and the moving fitting part 3 is moved parallel in the direction of a vector product obtained from the direction of the applied force 17 and axial moment 19 for force application. The existence of reaction caused by a catch between the protruding part 4b of protruding fitting part 4 and the fitting hole 3a of the recessed fitting part 3 at this time is detected, and in the case of detecting no reaction, force application in the direction of the vector product is performed until reaction is detected.
