摘要： PURPOSE:To quickly make possible the discovery of a damage part by visual observation if the damage part should occur in a glove by providing a transparent (or semitranspaent) layer positioned on the surface and a changeable color layer changed by the change of pH in contact therewith. CONSTITUTION:A first layer 11 positioned on the surface consists of a transparent or semitranparent buck-up material, a second layer 12 is composed of a changeable material containing a color changing raw material by the use of the change of pH and a third layer 13 consists of a constitutive material of a glove body. By this constitution, when a layer composed of the constitutive material of the glove body is exposed under outside environment to produce a pin hole and quality inferiority in use, chemicals are invaded from the damage part 14. Thereby, since the raw material of pH indication in a color changeable layer is color-changed, the damage part 14 can be discovered easily.

摘要： PURPOSE:To enable complete cleaning in a magazine by allowing cleaning plate to come into contact with the bottom surface of the magazine when a pusher moves forward and leave the magazine bottom surface when the pusher moves back. CONSTITUTION:When the pusher 30 is moved forward, a weight 64 moves forth together abutting on a base body 61 because of contact resistance to the magazine bottom surface 22. While the pusher 30 moves forward, the cleaning plate 62 extrudes deposits on the magazine bottom surface 22 to clean it. When the pusher 30 is moved back, on the other hand, the pusher moves back abutting on a stopper 71 because of the contact resistance. The cleaning plate 62 rotates counterclockwise to move up, so even when the pusher 30 is moved back, the deposit are not scraped and gathered.

摘要： PURPOSE:To enable non-uniform fluctuation which is generated in Raman conversion medium to be eliminated, its relaxation to be promoted, high-repetition oscillation to be stabilized, and energy to be saved by providing a multi-bus cell for non-saturation conversion and a multi-bus cell for saturation conversion. CONSTITUTION:A Raman conversion multi-bus cell consists of two parts 1 and 3, where one multi-bus cell is a multi-bus cell for non-saturation conversion 1 and temperature conditions etc., can be set freely. On the other hand, the other multi-bus cell is the multi-bus cell for saturation conversion 3 and flow of para-hydrogen is produced within this cell 3 only. Then, Raman conversion of paths excluding 2-3 paths before Stokes light power is saturated and immediately before saturation is performed within the cell 1 and then 2-3 paths immediately before saturation are performed within the cell 3 through a collimator 5 or a mirror system 5, thus enabling fluctuation which is generated due to cooling accompanying Raman conversion to be eliminated or the relaxation to be promoted, a stable and high-repetition Stokes light oscillation to be achieved, and a highly efficient conversion to be made.

摘要： PURPOSE:To improve the maintenance efficiency and the reliability of examina tion by installing an accelerometer on the main body of a mechanical snapper. CONSTITUTION:In examination system during the service period of an earth quake-proof holding device used in an atomic power plant, a mechanical snapper 3 is installed between a piping 1 and a fixing wall 2 in an atomic furnace stor ing container A. In the mechanical snapper 3, when a surface pressure acting to a ball screw 4 reaches a specific value and a ball unit 5 is moved, a mechani cal vibration is generated to the mechanical snapper 3 and a piping holder system. To detect this vobration, a small accelerometer is installed. As a result, the vibration can be detected in a simple device. Furthermore, no variation of the index value owing to a drift is generated, and a highly reliable detection can be carried out constantly.

摘要： PURPOSE:To remove deteriorated substances without using chemical agents, to use a solvent re-cyclically with a large treatment capacity and without any danger such as a fire, and to reduce a generating amount of radioactive wastes, as well, by treating spent solvents by freezing process. CONSTITUTION:Spent solvents 1 containing a TBP (a phosphoric ester) and higher carbon oxides are treated by a freezing process, using a freezing device 2 at temperature lower than soldifying point of the higher carbon oxides and higher than that of the TBP. Accordingly, the spent solvent is separated into a frozen solid body 3 mainly consisting of the higher carbon oxides and a solution 4 containing concentrated TBP which does not freeze. Besides, deteriorated TBP and the like remain in the solution without freezing. In such a way, each content can be very effectively separated and concentrated by the freezing process and therefore safety of the process can be well improved without any danger of a fire.

摘要： PURPOSE:To improve a multimode Raman laser system in conversion efficiency and to dispense with an amplifier constituted in multistage by a method wherein an unstable resonator type oscillator is used as a TEA CO2 laser device, and a multimode Raman cell is employed as a Raman cell. CONSTITUTION:An unstable resonator type oscillator is used as a TEA CO2 laser device 11, and a single longitudinal mode CW-CO2 laser device 2 is employed as an injection light source of feeble circular polarized light. A circular polarized high power laser beam emitted from the TEA CO2 laser device 11 is injected into a multimode Raman cell 16. The multimode Raman cell 16 is composed of an SUS pipe with a pair of concave mirrors provided to both its ends respectively, where a laser beam injection hole 17 and a laser beam output hole 18 are provided to the concave mirrors respectively and the SUS pipe is charged with parahydrogen gas. A circular polarized high power laser beam incident through the laser beam injection hole 17 induces scattered light 16mum in wavelength through a Raman effect of parahydrogen as being repeatedly reflected by a pair of concave mirrors, and the scattered light is emitted through the laser beam output hole 18.

摘要： PURPOSE:To simplify maintenance and inspection works and to detect vibratory wave as well by detecting the vibratory wave generated when a control rod of a control rod drive mechanism collides with a reactor core support plate. CONSTITUTION:When excitation of a supporting electro-magnet is released and a control rod 341 falls down to a lower guide tube 361, the control rod 341 collides with a reactor core support plate 35 and vibratory wave M is generated. This vibratory wave M is propagated through the reactor core support plate 35 to a control rod 342 of an adjacent control rod drive mechanism, and then is propagated to an accelerometer 39 via an extention tube 332 and a driving part 312. Falling-down of the controlrod 342 is commenced by releasing of excitation of the supporting electro-magnet, and is ended by propagation of the vibratory wave M to the accelerometer 39, and scram time is measured by time difference between commencement and ending of the falling-dowm.
