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 provide resin molded coils and their manufacturing method which makes it possible to reduce the number of blocks by sealing an insulating gas into void in conductor and hardening the injected resin. CONSTITUTION:A coil 4a provided with a wound conductor 2 and an insulating paper 3 that is inserted among the conductor layers and a sealing tube 7 that seals an insulating gas at 10-760Torr supplied from outside is molded with resin to form a resin molded coil. After resin injection into the coil 4a set in a metallic mold 8 is finished, an insulating gas at 10-760Torr is sealed from the sealing tube 7 by an outside cylinder, etc. After the sealing, the sealing tube 7 is closed with a plug 9 so as to prevent leakage of the insulating gas to outside. After this the resin is hardened. For the insulating gas SF6 or flon gas is used. The sealing tube 7 is formed by a pipe 7a that is made by forming a void in part of the conductor, and it is taken to outside through the terminal 10 of the resin molded coil connected to the metallic mold 8, and the opening in outside is provided with a plug.

摘要： PURPOSE:To prevent possible cracks with a lower axial stress of a molded coil by winding thin sheet conductors with an electromagnetic winding which is molded with a thermosetting resin, while the conductors are partially slitted perpendicular to the width, thereof. CONSTITUTION:Thin sheet conductors 5 are provided with an intermediate slit 7 widthwise. That is to say, a winding is made around the two thin sheet conductors so arranged as to be the same in the potential with the slit 7 interposed between inter-layer insulators 6. As one widthwise end of the conductors 5 is fixed with a resin section 4 while the other end thereof is slitted, conductors will be displaced easily when encountering any widthwise heat expantion thereby lowering axial stress of the molded coil and preventing possible cracks.

摘要： PURPOSE:To reduce the insulation distance of conductors and to make a transformer compact, by enclosing the conductors in a gas filled space when an electromagnetic coil of a resin-molded three-phase transformer is connected to three-phase bus lines by the use of connecting conductors. CONSTITUTION:Current terminals 3 of a molded coil 1 constituting a transformer is connected to the ends of connecting conductors 2 which pierce through a molded bushing 4, and the conductors 2 are connected to three-phase bus lines 6 by way of a spacer 7. In this constitution, a sheath 9 is provided to surround the conductors 2 on the portion from the bushing 4 to the bus lines 6, and an insulating gas comprising SF6 gas or the mixture of SF6 and flon gas is filled in a surrounded space 5 and sealed. In this method, the distance l' from the side of the coil 1 to the spacer 7 is reduced to about 1/2 that of the conventional constitution, thereby the size of the transformer becomes compact accordingly.
