摘要： PURPOSE:To improve working efficiency of volume reduction treatment work and to decrease required cost by providing a waste body transfering mean by which the waste body brought into a housing is transfered to a specified cutting process position, a processing mean utilizing a submerged laser, a collection cask and the like. CONSTITUTION:A spent fuel assembly 3 is severed into a fuel body and a channel box 8 and thereafter the channel box 8 is lifted by a transfer machine 5 to be housed in a housing 4 and then is lifted down until its lower end reaches a specified cutting process position, in order to be held by a holding guide 4d. After that, a laser oscillator 10 and an assisting gas supplying source 11 are given by an operation order and a laser processing head 6 is made to swing and move along a surface of the channel box 8. Severed segments 8a fall into water within the housing 4 and are received by the collecting cask 7. The assisting gas is also collected by an exhaust gas collector device 14 via a gas piping 15, and suspended fine cruds generated in the water and the like are removed by a filter of water purification device 16.

摘要： PURPOSE:To make a minute hole of the same size being free from a variance all the time by detecting a laser light for passing through a hole when the hole is penetrated, at the time of making a hole in an object to be worked by the laser light, and stopping an oscillation of the laser light. CONSTITUTION:By a signal from a controller 8, electric power is supplied to a pulse type laser oscillator 1 from a power source part 7, and a laser light 2 is oscillated and sent to a working use lens 4 through a bend mirror 3, and condensed and radiated to the surface of a piercing part 11 of an object 5 to be worked. When a hole is penetrated by irradiating repeatedly a pulse of the laser light 2 to the piercing part 11, the laser light 2 passes through the hole and irradiates an ND filter glass plate 9, and the laser light 2 is attenuated. This attenuated laser light 2 is detected by a photodetector 10, a detecting signal is sent to the controller 8 and the electric power supply to the oscillator 1 from the laser power source 7 is stopped. In such a way, a minute hole of a prescribed outside diameter can always be formed in the object 5 to be worked.

摘要： PURPOSE:To ensure normal flow rate characteristics by constituting an apparatus such that a laser beam is irradiated on the surface of a minute gap regions of upper and lower resin mold members on which foil mirrors are easy to deposit and scans the resin mold members while moving them. CONSTITUTION:A laser beam 24 generated from a laser oscillator 21 is collected by a condenser lens 26 via a bend mirror 25 and irradiated on the surfaces of the minute gap regions 27 of upper and lower mold members 8 and 9, respectively, on an X-Y tale. At this time, the table 22 is reciprocated in an X axis or a Y axis direction at a repetitive small pitch feed by a computer control unit 23. Instantaneous evaporation is generated in the regions 27 and an approximately uniform and suitably rough surface condition is obtained. Thus, the deposit of foil mirrors is removed and surely normal flow rate characteristics are ensured.

摘要： PURPOSE:To reduce material cost and mandays by mounting a contact consisting of silver-based material on a supporting body having a surface of copper-based material, and heating them in a specified temperature range in a nonacidic gas atmosphere at an atmospheric pressure for forming a diffused attachment layer. CONSTITUTION:A silver-based contact 1 and a supporting body of a base 2 consisting of copper are cleaned, the contact 1 is mounted on the base 2, and these are heated at temperatures within 700-870 deg.C corresponding to applied material at an atmospheric pressure in a furnace having a nonacidic gas atmosphere. As a result of this heating, Ag atoms in the contact and Cu atoms in the base are mutually diffused so as to form a diffused attachment layer in the middle state of solid and liquid by reaction at the contact part of both. By cooling it gradually or quickly, the contact 1 is attached to the base 2. In this manufacturing method, use or insertion of silver wax or flux is eliminated, the material cost and mandays are reduced, and it can be applied in a wide range for attaching silver-based contacts at a high reliability.
