The heat shield unit 20 is formed of a heat shield plate 22 on which the cooling pipe 15 is directly mounted, and a multilayer reflecting plate situated on a cryostat 1 side. The heat shield plate 22 is mounted on the cryostat 1 side by supports 25, 26. The upper support 25 is constituted so as to have large vertical rigidity so as to support the whole weight of the unit 20 and be capable of following thermal contraction. The lower unit 26 has a role of holding the space between the unit 20 and the cryostat 1, and both the supports 25, 26 are made of titanium alloy.

摘要： PURPOSE:To prevent a core from becoming crushed and also a warping phenomenon due to bending from occurring by providing the first and the second sliding mechanism for moving a pressing plate, and a drive mechanism for displacing a pressing plate tip in a direction where a honeycomb plate is curved through the sliding mechanism. CONSTITUTION:A pressing plate 2 is formed using a high rigidity plate material such as steel plate, and is supported by the first and the second sliding mechanism 6, 7 respectively. Further, these pressing plates 2, guided by the sliding mechanisms, are arranged at an opposite position in a freely movable manner in a direction where the plates become separated from and come in contact with each other, that is, in the longitudinal direction of a honeycomb plate 1. In addition, it is so designed that the honeycomb plate 1 is attached to an area between the pressing plates 2, 2. If a lifting frame 4 is moved up and down by a drive mechanism 5, the tip of the pressing plate 2 moves up and down with the lifting frame 4 and the second sliding mechanism 7. The honeycomb plate 1 made using a flat plate is bent by lifting the lifting frame up gradually due to the activation of the drive mechanism 5.

摘要： PURPOSE:To eliminate the cause of separation by removing the inner cylinder of a spool after a superconducting coil has been impregnated with a synthetic resin and fixed. CONSTITUTION:An inner cylinder 1 is formed by combining split bodies 1a of an inner cylinder 1 and flanges 2 are fitted to the outer periphery at the opposite ends thereof and at the same time, a spool 4 is formed by fitting a holding nut 3 to the inner periphery. The holding nuts 3 are fitted to the inner periphery of the inner cylinder 1 at the opposite ends thereof and held in place with the inner diameter thereof being enlarged. A superconducting wire 8 is wound on the inner cylinder 1 in multistage and the wire 8 is impregnated with a synthetic resin and secured in place. In this case, when the superconducting wire 8 is made of Nb3Sn, for example, after heat treatment at temperature of about 700 deg.C, the wire is fixed by impregnating with the synthetic resin. The inner cylinder 1 can be taken away easily by removing the holding nut 3 after the superconducting wire 8 has been impregnated with the synthetic resin and fixed and then removing each split body 1a of the inner cylinder 1 and drawing the inner cylinder 1 in the axial direction.

摘要： PURPOSE:To avoid a concentration of the stress on a weld zone to require a seal and to improve the strength of the weld zone and the safety by fitting a strap plate to cover a welded joint of base metals on step parts formed to clad layers and welding an indentation part between a side part of the strap plate and the step parts. CONSTITUTION:A part of the tip of the clad layers 1 such as titanium, etc., is removed to form the step parts 8 and a welding groove is formed with the 2nd step part with the base metals exposed on the tip of the step parts 8. After the welded joint to connect the base metals mutually by the welding groove is formed, filler metal 11 consisting of titanium, etc., is mounted on the welded joint and the 2nd step part to cover these and next, an interval between the filler metal 11 and thin clad layers 9 is tack-welded and afterward, the strap plate 12 consisting of titanium, etc., is mounted on the 1st step parts 8 and the filler metal 11. Then, the butt-welding is performed by the indentation part formed between the side part of the strap part 12 and the 1st step parts 8 which is connected in a plane state with the surface of the clad layers 1 to avoid the concentration of the stress on the weld part.

摘要： PROBLEM TO BE SOLVED: To allow the weld zone at both ends of an already installed bent pipe to be welded without detaching it and also to enable the device to be used even in the case of a short pipe. SOLUTION: A bent pipe R is abutted on V-blocks 13a, b on a pipe supporting arm 11 having the same angle as formed by the center axis of the bent pipe, and fixed with a clamping mechanism 22, with the pipe supporting arm 11 attached to a supporting base 19 so as to be movable in the inverse and axial directions around the bisector. The supporting base 19 is rotated coaxially with one center axis C1 of the bent pipe R. As a result, circumferential welding is done for the weld zone at one end of the bent pipe R, and then, the remaining circumferential welding is made possible by merely rotatably reversing the pipe supporting arm 11. In addition, even with a different diameter of the bent pipe R, the V-blocks 13a, b are moved on the pipe supporting arm 11, and moved integrally with the pipe supporting arm in the axial direction on the bisector thereby making the center axis of the bent pipe R coincide with the rotary shaft of the supporting base 19, and enabling the welding easily.

摘要： PURPOSE:To provide a neutron generating device which can generate neutrons stably while preventing the target substance from seething. CONSTITUTION:A charged particle beam (d) is passed through an incident hole 8 from a beam duct 7 and put incident to a reaction chamber 4 to be implanted into a target substance 1 so that a nuclear reaction takes place, and thereby a neutron beam (n) is produced. Evacuation of the beam duct and reaction chamber is made by an evacuating means 9 connected with the beam duct. With the incident hole an orifice pipe 10 is connected so that the charged particle beam is put incident through the pipe and also a differential pressure is generated between the reaction chamber and beam duct by the evacuating resistance of the pipe, wherein the degree of vacuum in the chamber is set lower than that in the beam duct. It may also be accepted that a differentially evacuating mechanism is introduced using a plurality of orifice plates, in lieu of the mentioned orifice pipe 10.
