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 enable in use of a coil insulator having flexibility in an environment having high temperature and radioactivity by fixing part of the surface of mica powder with thermoplastic resin, and bonding between the surface of the remaining mica powder and a mica base material with an inorganic adhesive. CONSTITUTION:The surfaces of mica powder 4 are fixed with short fiber or particles of thermoplastic resin 7 to form a mica base material 3. The resin 7 is used in case of short fiber or particles of the resin 7 due to bond by the entanglement of the powder 4 though the resin 7 coats the entire powder 4 in case of liquid organic binder. Accordingly, the resin 7 does not coat the entire surface of the powder 4, but can fix with part of the surface of the powder 4. Then, an inorganic adhesive 5 is immersed in the material 3 around when or in the course while this material 3 is wound on a coil conductor, thereby forming a coil insulator by adhering between the powders 4 and between the powder 4 and the material 3.

摘要： PURPOSE:To make possible the injection of a high-resistance corona shield layer in a mono-block form by forming a high-resistance corona shield layer with an iron- contained asbestos tape attached witha catalyst which works to accelerate curing of an impregnated resin. CONSTITUTION:An intermediate-resistance corona shield tape 4 is wound up after an insulation layer 3 is wound around a coil conductor 2. In addition, a high-resistance corona shield layer 7 formed by an iron-contained tape attached with a catalyst, is wound around the surface of the insulation layer 3, partially lapped by the intermediate-resistance corona shield layer 4. Then a cover insulation layer 5a is applied on the outermost side. Later a low-resistance slot liner 6 is wound around the whole layer and then the latter is housed in a slot on a stator core 1. Thus it is possible to obtain a corona shield layer for a rotary electric appliance equipped with a high-resistance corona shield layer which can be injected in a mono-block form.

摘要： PURPOSE:To prevent cracking by providing a fitting means for track on a broad reinforced plastic board placed on the upper side of a coil body and molding whole structure into an integral body using resin concrete. CONSTITUTION:On the upper side of the coil body provided a mica insulating layer 3 around a coil conductor 2 a reinforced plastic board 8 with a larger width than the coil body is placed. Bolts 10 for example are provided as the fixing means for the track on the board 8. Thus-obtained structure is molded into an integral body using the resin concrete 11 mixed gravel and sand in a thermoplastic resin. Whereby, the electromagnetic tending to raise the coil body is transmitted to the bolts 10 via the board 8 to reduce the stress working on the concrete 11.
