摘要： PROBLEM TO BE SOLVED: To enables the simultaneous work both for lifting and for reversing a core plate to be performed by constituting a core plate lifting and fixing tool so that each fixture can be fixed in a selected core plate hole with jaws movable in the radial direction by a vertical screw mechanism. SOLUTION: This tool includes upper and lower caps 36 and 38 and has upper and lower housings 40 and 42 between the respective caps. Jaws 62, 64, 66 and 68 are located in an opening in the upper housing 40. Each of the jaws 62 to 68 is partially threaded and is connected to sleeves 74 by an interlocking device 82 that axially rotates at both ends. The sleeves 74 are engaged by a screw on a shaft 76 held by bolt heads 78 and 80 of the caps 36 and 38. Therefore, the vertical action of the sleeves 74 on the shaft 76 in accordance with the rotation of the shaft 76 is converted to the horizontal radial motion in the upper housing 40 of the jaws 64 to 68. When fixtures are used, each of four fixtures 34 is inserted into a core plate hole and the jaws 62 to 68 are moved to the outside of a radial direction by rotating a rod 76 with an engaging tool of the bolt head 78.

摘要： PROBLEM TO BE SOLVED: To judge the operating direction directly only by watching the image of a mobile unit and enable the easy operation of it by controlling it so that the moving direction of a mobile unit indicated by an operating means can match with that of the mobile unit displayed on a screen. SOLUTION: An arm of a universal-head 4 is driven by operating a universal- head operator 6 to output universal-head operation signals 300 according to operations. The drive of the arm changes the picture-taking direction of a monitoring ITV camera 3 and allows a watching monitor 5 to show a cart 10. Watching the cart 10 in the watching monitor 5, a worker controls a ceiling crane operator 2 in the same direction as he wants the cart 10 on the screen to move. The operator 2 outputs operation command signals 100 to an operation command controller 9 according to operations, and the controller 9 outputs the signals 100 as motion command signals 600 to a crane 1. In response to the signals 600, the crane 1 moves the cart 10. In other words, control is exercised so that the actual cart 10 can really move in the direction displayed on the screen by matching up the moving direction of the cart 10 on the screen of the monitor 5 with the operating direction of the operator 2.

摘要： PURPOSE: To move a gutter spring composed of a conductive material arranged in the pressure tube of a reactor while being fixed to the circumference thereof with a primary coil being provided. CONSTITUTION: Power is fed such that a primary coil can generate a primary electromagnetic field transmitting through the wall of a pressure tube 29 to induce an eddy current in a gutter spring 35 when it is located closely thereto. The primary coil 65 comprises a core 67 having high permeability and an AC current is fed to the primary coil 65 such that an AC primary electromagnetic field is generated. A conductive band 73 is wound continuously around a part of primary coil 65 and coupled electromaqnetically therewith thus generating a phase shifted AC secondary electromagnetic field.
