摘要： PROBLEM TO BE SOLVED: To enable hazardous works by a robot, using an underwater inspection/repairing painting vehicle, for remotely scanning each work of an inspection for painting the inside of S/C, blister elimination, repairing painting, and film thickness inspection by a diver that is being discussed with the conventional method. SOLUTION: With underwater works, such as blister elimination and repairing paint requiring human visual inspection and repairing, each kind of work tool is installed in an XYZ scanning mechanism, that is mounted to an underground vehicle 100 that is steered remotely underwater in the S/N of a nuclear power plant, work such as blister detection/removal, and repairing paint is executed by the underwater vehicle 100, and the positional deviation of the underwater vehicle 100 is prevented by the pressing of the vehicle itself, using a thruster that the underwater vehicle 100 itself preserves, thus securing work position.

摘要： PURPOSE:To raise the reliability and operability of construction work by a method in which a key-shaped anchor rib is welded to a steel plate, and a side-threaded reinforcing bar coupler is attached to a threaded reinforcing bar and welded to a recession while regulation an installing error. CONSTITUTION:A key-shaped anchor rib 11 is welded to a steel plate 4, and a side-threaded reinforcing bar coupler 7 is attached to a threaded reinforcing bar 6. The coupler 7 is welded to the recession of the rib 11 while regulating an installing error, horizontal beams are set, and concrete is placed. In this case, the welding points of the coupler 7 and the rib 11 are four. Since the setting error of the reinforcing bars and the anchor system can be easily absorbed, the reliability is enhanced and the setting operation of reinforcing bars and the placing operation of concrete can be simplified.

摘要： PURPOSE:To enable inspection at a narrow part by moving a frame along a tube to be inspected, and positioning a film holding part at an inspection position and photographing it on a film. CONSTITUTION:The arcuate frame 10 formed by fitting a radiation projection part 38 to the tube 7 is provided movably in the circumferential and axial directions of the tube 7. Then, a moving body 18 where the film holding part 23 is fitted rotatably is moved to nearby a weld line C as the inspection position of the tube 7 and the holding part 23 is moved out toward the inspection position to set the film at the inspection position. Then, radiation is projected upon the inspectrion position from a radiation part 38 to photograph the inspection position on the film. The holding part 23 is moved back toward the moving body 18 after the photography to release the tube 7 from contacting the film, and the moving body 18 is moved to nearby the hand to replace the film. A film is returned to the inspection position after the film replacement and the frame is rotated and set at another inspection position to take a picture again; and the entire periphery of the weld line C is thus photographed to inspect whether or not there is a defect at an inspection position at a narrow place in the guard tube 9.

摘要： PURPOSE:To automatically adjust an axis shift and easily search for a communication target as well as communicate more information irrespective of adverse influence or the like of external noise. CONSTITUTION:Since diffusion light 14, 15 is emitted to each other at the time of searching for communication targets, a wider searching range at the time of emission than a case where condensed light is used can be obtained to facilitate searching. In addition since a light transmitting/receiving part rotates in horizontal and elevation angle directions, searching can be done easily and securely even if there is difference in height between both communicators. If communication is performed with condensed light 13, transmission/reception with high frequency signals is possible, a loss due to light diffusion can be further reduced, and also adverse influence of external noise can be prevented, thereby enabling communication of much data.

摘要： PURPOSE:To prevent the vibrations of a articulated manipulator by controlling the operating force based on the estimated exciting force. CONSTITUTION:A manipulator joint control part 10 outputs the joint angle command value to a driver circuit 50 in each control step in response to each joint of an articulated manipulator 60. The circuit 50 controls the joints of the manipulator 60 by a control system. An arm posture arithmetic part 20 calculates the length of a link of a component rectangular to the direction of gravity based on the angle command value of each joint decided by the circuit in each control step as well as the link length. A joint load torque arithmetic part 30 calculates the estimated load torque of each joint in each control step and then calculates a load torque fluctuation component, i.e., the difference between said estimated torque and the load torque applied to each joint. A joint angle correcting value arithmetic part 40 calculates the joint angle correcting value from said load torque fluctuation component and the obtains the corrected joint angle command value in consideration of the load torque fluctuation component to output this command value to the part 10.
