Thereafter, a first axial direction yarn layer is formed by laminating an axial direction yarn R arranged in the axial core direction of the mandrel 7 on the first oblique yarn layer. Then, a second oblique yarn layer is formed by laminating by wieving the oblique yarn S by the same specific angle on the first axial direction yarn layer. By laminating hereafter the axial direction yarn layer and the oblique yarn layer alternately in the same way, a cylindrical textile fabric is formed. After fitting suitable matrix to the cylindrical textile fabric, the forming is carried out. Thereby, a reinforced fiber resin made tube body for passing fluid therethrough is obtained.

摘要： PURPOSE:To efficiently manufacture a superconductive multicore by arranging a raw material mixture constituting a superconductive material in plural isolation chambers formed by arranging an insulating member inside a cylindrical body respectively, while giving a plastic process to this member to be processed so as to fire or anneal a substance in each isolation chamber before and after this plastic process. CONSTITUTION:Plural isolation chambers 4... mutually independently extending from one end to the other end are formed by fitting and arranging an insulating member 3 inside a cylindrical body 2. Next, a member to be processed 1 formed by arranging a substance constituting a superconductive material in the isolation chambers 4... respectively is extrusion-processed so as to contract a diameter. Then, after the extrusion process the member to be processed is arranged inside a furnace having a proper temperature, a raw material substance inside the isolation chambers 4... is fires or annealed for forming plural core parts consisting of a superconductive sintered substance inside the isolation chamber 4... so as to constitute a superconductive multicore. Accordingly, it is needless to manufacture a wire rod constituting each core part and moreover a crashing process of the sintered substance comes to be needless to be performed.

摘要： PURPOSE:To efficiently manufacture a superconductive multicore by sticking a mixture, in which powder of a raw material substance constituting a superconductive material is mixed with a solvent, to the peripheral surface of a long-measured insulating member for forming plural separated core parts while removing a part of it followed by firing the stuck part before and after this process. CONSTITUTION:A mixture constituted by mixing powder of a raw material substance constituting a superconductive material with a solvent is made to stick to the peripheral surface of a long-measured insulating member. Next, plural separated core parts 3... extending from one end to the other end of the insulation member 11 are formed by removing a part of a stuck part 2. Further, the core parts 3... are dried for being fired under an appropriate temperature to be made into the superconductive core parts 3... so as to obtain a superconductive multicore. Further, thereafter the outer part of this superconductive multicore may be given insulating coating. Thereby, the process starting from the raw material substance constituting the superconductive material to obtaining the multicore is prereduced so as to make crashing or the like of the superconductive sintered substance hard to be processed needless.

CONSTITUTION:A mold 3, having the grooves 1 on the surface corresponding to a coil part and the grooves 2 corresponding to a lead part, is formed and then a superconducting raw material powder layer 4 is formed on the surface of the mold 3. Then, the surface layer on the surface is removed leaving the superconducting raw material powder in the grooves 1 and 2 of the mold 3, the entire mold 3 is surrounded by an elastic film body 5, and the superconducting raw material powder is brought into the state of high density. Then, said powder is placed in an electric furnace 6, sintered at 900-950 deg.C, and a coil-like molded body 10 is obtained. The superconducting material coil-like molded body 10 is then dipped into the paste-like insulating material 11 consisting of a synthetic resin material, and it is finished as the superconducting material coil. As a result, the coil can be formed small in size, and its current density can be improved.
