摘要： PURPOSE:To prevent the resin of an insulation layer from flowing out by a method wherein a coil is composed of a conductor made of copper base and superconductive wires buried in the base and a layer insulation applied to the radial direction of the conductor and the layer insulation is made of specific glass-fiber reinforced plastic fine leaf material. CONSTITUTION:A superconductive coil is composed by winding a coil conductor 2 like a race-track. The conductor is composed of a copper base 3 in which a groove is formed and superconductive wires 4 which are laid and transposed in the groove and are buried and fixed by solder 5. To the side of the conductor 2 thermoexcel surfaces 6 for cooling are provided, an interlayer insulation 11 is provided between the adjacent conductors 2 and glass-fiber reinforced plastic fine leaf material which contains 20-40wt% of resin is used as the interlayer insulation. Medium temperature thermosetting resin 12 is applied around the insulation 11. With this constitution, the resin is prevented from flowing out of the insulation 11 and the coil is endurable enough against repeated compression stress. Moreover, the surface 6 are not contaminated, so that the heat emission effect is not inhibited.

摘要： PURPOSE:To maintain constant gaps between thermo excels when stress fatigue is exerted, by placing fiber base material impregnated with heat hardening resin between spacers and the surface of the thermo excels. CONSTITUTION:Thermo excels 9 having a uneven surface are provided to accelerate cooling by increasing contact area with a coolant at a passage of liquid He on the surface of coil conductor 2. Between the thermo excel surface 9 and the spacer 7, is placed a fiber base material 11 impregnated with heat hardening resin. The thickness of the base material 11 is preferably 1/4-1/3 of the thickness of the surface 9. The gap between the surfaces 9 is kept almost constant preventing slackness of the entire magnet and deterioration of cooling effect.

摘要： PURPOSE:To retain dielectric property of a mold coil with a layer insulator and to obtain the coil of large shearing adhesive strength and of difficult separation by employing heat resistant film for thin insulator arranged among laminated conductors and bonded to the conductors with synthetic resin and arranging glass non- woven fabric on both sides thereof. CONSTITUTION:A layer insulator 7 is formed by using heat insulating film 1 of aromatic polyamide or the like as a core material and arranging glass non-woven fabrics 2, 3 on both sides of the film 1, and arranged between coil conductors 4. Thus, it can obtain sufficient dielectric property and 20-30X10 cm/cm/ deg.C. of thermal expansion coefficient of glass non-woven fabrics 2, 3 approaching to 17X 10 cm/cm deg.C. of thermal expansion coefficient of the coil conductor 4 to thereby reduce the residual shearing stress caused due to the difference of the thermal expansion coefficients therebetween to thereby improve the shearing adhesive strength of the insulator.

摘要： PURPOSE:To obtain a slide insulating plate durable for the repetition of sliding under a surface presseure, by means of applying a lubricant on the hardened insulating plate on surface of which finely recessed parts are constructed. CONSTITUTION:As a core material 2, is used a soft aromatic polyamide paper or nonwoven fabric, having a good holding of the lubricant perfluoropolyethel, with a density of 0.2 to 0.4g/cm . On both sides of said core 2, is consturcted a slide insulating plate, made by pasting together a hardened aromatic polyamide paper 1 with a density of 0.7 tod 1.0g/cm . And with FRP plate used for the core material 2, many of finely recessed parts 3 are formed in surfaces corresponding to the insulating plate 1 in the both sides made of the above described hardened aromatic polyamide paper 1, and the slide insulating plate, that holds the above described lubricant within said recessed part 3, is constructed. The slide insulating plate, constructed in such method as said in the above, if selectively applied for in accordance with the purpose, can be fully durable for the sliding operation under a surface pressure between the coil and the conductor and between the coil and the fixed material.

摘要： PURPOSE:To raise the mechanical strength of winding and insulating material at the time of operation by raising adhesion with conductor by the procedure in which a resin-treated fibrous base material is wound around the innermost layer of winding conductor and then its outside layer is wound with an insulating material and subjected to hot forming treatment. CONSTITUTION:The resin-treated fibrous base material 5, e.g., glass cloth, glass unwoven fabric, etc., is wound around the conductor 2, its surface is wound with the pre-preg polyimide film 3, and then its surface is further wound with the pre- preg mical tape 4 into a definite turn to form the winding 1. The formation of such a winding insulated layer increases greatly the adhesion between the conductor 2 and the pre-preg polyimide film 3, thus preventing the winding insulated layer from exfoliation due to mechanical stress during operation and also raising electric characteristics.
