摘要： PURPOSE:To prevent damage, such as the collapse, cracks, etc. of a flexible pipe by compounding a specific quantity of an aromatic polyamide fiber to a cold-setting type epoxy resin in padding. CONSTITUTION:A mixture in which 1 or 5wt% aromatic polyamide fibers are compounded to a 100wt% cold-setting type epoxy resin is used as padding. The padding is solidified, an insulating layer is shaped, and the padding is cured completely. Accordingly, the padding 7a resists electromagnetic stress sigmaapplied to a coil 1a and protects a flexible pipe 6, thus obtaining the coil 1a capable of preventing damage, such as the collapse, cracks, etc. of the flexible pipe 6.

摘要： PURPOSE:To reduce the amount of liquid helium by forming a liquid helium container into a hollow cylinder, and then making a vacuum container covering it as bucket type. CONSTITUTION:The liquid helium container 2 is formed into the hollow cylinder, and the vacuum container 3 is made as bucket type. Such a cryostat 7 makes it enough that the amount of the liquid helium 7 is small, and accordingly the heat penetration from outside is also small. Besides, since the surface area of the container 3 is small and extends only over the outer periphery of a flange junction, the decrease of vacuum degrees is gentle. Therefore, it is sufficient that the amount of the liquid helium is small, and the heat penetration reduces. As a result, the small amount of liquid helium evaporation is enough.
摘要翻译：目的：通过将液氦容器形成中空圆柱体，然后将真空容器覆盖为桶型来减少液氦的量。构成：将液氦容器2形成为中空圆筒，真空容器3为桶型。这样的低温恒温器7使得液氦7的量足够小，因此来自外部的热量渗透也很小。此外，由于容器3的表面积小，仅在凸缘接合部的外周延伸，所以真空度的降低是平缓的。因此，液氦的量少，热渗透性降低就足够了。结果，少量的液氦蒸发就足够了。

摘要： PURPOSE:To raise the uniformity of magnetic field by restraining the eddy current generated in a bobbin of the solenoid coil by using anisotropic fiber reinforced plastics in which the heat-shrinkge coefficient is different between in the circumferential direction and in the axial direction, for the bobbin. CONSTITUTION:A superconductive wire 3 is wound around a cylindrical bobbin 2 to be into solenoid-form and a band layer 4 is arranged on the periphery of said wire 3, thereby forming a superconductive solenoid coil 1. The bobbin 2 is composed of anisotropic fiber reinforced plastics (ERP) in which the heat-shrinkage coefficient is 0.25% or less in the circumferential direction and that is 0.3% or more in the axial direction when the bobbin 2 is cooled down from the room temperature to 4.2K. When the bobbin 2 made of FRP is fabricated, wide cloth 6 absorbed with resin is rolled around a mandrel 5 repeatedly into a baggy form. This cloth 6 is made of mixed fabric in which the weft consists of glass yarn and the warp consists of yarn of carbon group or that of combination of carbon and glass group. Then the eddy current generated in the bobbin 2 is restrained, thereby improving the uniformity of magnetic field.

摘要： PURPOSE:To eliminate corona discharge between a liner and a core for a rotary electric machine by winding mica-containing aromatic polyamide paper on a winding in such a manner that the mica-rich surface is disposed outside to form the liner so as to enhance the wear resistance of the liner. CONSTITUTION:A slot liner material 7 is formed by coating low resistance carbon paints 10a, 10b on both surfaces of a sheet material made of an aromatic polyamide paper layer 8 and a mica-rich aromatic polyamide paper layer 9. The slot liner material 7 is so wound on a stator winding 3 that the mica-rich surface is disposed outside. Since the surface having excellent wear resistance of the liner material 7 is disposed outside on the stator winding, it can reduce the wear due to the slide between the core and a spacer to maintain the surface resistance rate within allowable value so as to eliminate corona dischage between the slot liner and the core.

摘要： PURPOSE:To ensure a safety operaion with a non-destructive inspection made operable for the coil in operation, by such means that, between the coil peripheral surfaces and an external frame be provided an electrode layer, with an electrostatic capacity made measurable between said electrode layer and the external frame. CONSTITUTION:In the periphery of a coil main unit 2, with a peripheral insulation applied, on the side of a center block 6 of the coil and on the top of a coil, positioned in perpendicular to the before said, is arranged an electrode layer 7 likely as conductive tape, metal sheet or conductive paint, etc. In this way, during an operaton, if caused an anomalous deformation and destruction in a filling material 5, charged between the coil main unit 2 and the external frame 3, an electrostatic capacity is varied between the electrode layer 7 and the external frame 3, consequently with the above condition made easily detectable even during the operation, and in case of a damage being caused in the filling material 5, a work of repair can be operated by means of injecting a mending resin 10 into from an injection hole 9 of the external frame 3. The electrode layer 7 may be provided in the filling material layer 5 and/or in an outer clad insulation layer of the coil 2.
