摘要： PURPOSE:To enhance stability, by providing both field winding and armature winding to a stator facing both of them and by adding a means to change the flux interlinking the armature winding. CONSTITUTION:A field winding 2 is provided to a winding shaft 1 to form electromagnetic force for producing the field. A rotating shield body 3 is composed of a superconductor 3b and a supporting substance 3a to support it mechanically and is arranged on the outside circumference of a field electromagnet through a gap 4. On the outside circumference an armature winding 5 an a magnet core 6 are arranged. When magnetic field is produced to the field winding 2 by causing the current to flow and a rotating shield body 3 is rotated, voltage is induced to the armature winding 5. Since both field winding 2 and armature winding 5 can thereby be provided to the stator, a superconductive motor can be made solidly.

摘要： PURPOSE:To improve reliability against sudden temp. change at the time of introducing liquid helium by a method wherein a cryostat of FRP is formed by setting up a member with small heat shrinkage rate, according as from outer diameter side in the bath to inner diameter thereof. CONSTITUTION:As to a cryostat, an inner bath 1 of FRP is made integral with an outer bath 2 airtightly and a vacuum thermal insulating barrier 3 is formed by being evacuated from a vacuum exhaust vent 4. As to the inner tank 1, FRP layer 13 at outer diameter side of a gas transmission masking layer 11 consisting of an aluminum foil etc. is constituted of glass mat base and a FRP layer 12 at inner diameter side thereof is constituted of a glass roving base. Just then, since heat shrinkage rate of the layer 12 is smaller than heat shrinkage rate of the layer 13, thermal stress is small, and crack and exfoliation do not generate even though sudden temp. change is occured at the time of introducing liquid helium 8 etc.

摘要： PURPOSE:To facilitate the formation of a resin curable material having small thermal shrinkage by winding an epoxy prepreg glass tape having specific composition in a plurality of layers in circumferential direction on the outer periphery of a coil body, and winding the tape having different composition in a toroidal shape on the outside. CONSTITUTION:A layer wound with a plurality of layers of epoxy prepreg glass tape 6a containing 40-60wt% of resin content in a circumferential direction is formed on the outside of a superconductive coil body 2, and an epoxy glass tape 6b similarly containing 0-20wt% of resin content is wound on the outside in a toroidal shape. The thickness of the entire layer is larger than the gap between the coil body and a metal bobibin. After the bobbin is shrink-fitted to the coil body, the entirety is heated to cure the prepreg glass tape layer in the state that pressure is applied to the layer. In this manner, a cured resin having small thermal shrinkage of substantially the same level as the coil body and the bobbin can be readily filled in the gap therebetween.

摘要： PURPOSE:To largely improve resistive mechanical stress characteristics against bending stress by a construction wherein an insulating layer is composed of plastic film insulation for principal insulation and plainly woven glass cloth and glass cloth for armour insulation. CONSTITUTION:A coil conductor 2 is provided with plastic film insulation 3a for the principal insulation and plainly woven glass cloth insulation 3b thereon and further glass cloth insulation 4 having a coefficient of elasticity smaller than that of the plainly woven glass cloth 3b and fracture extension larger than that thereof to form the armour insulation. Given that the plastic film insulation 3a is P and the plainly woven glass cloth insulation 3b is G and the glass cloth insulation 4 is G', P is a prepreg polyimide film tape 0.06mm. thick and G is a plainly woven prepreg glass cloth tape 0.24mm. thick and G' is a prepreg glass tricot tape about 0.3mm. thick, all of them being 25mm. wide. These tapes are wound on a copper bar 3.2mm.X20mm. in cross-section and 300mm. long by P=5 turns of half rope +G=2 turns of half rope +G'=3 turns of half rope, whereas the forming of the coil is carried out at 130 deg.C for 15h by adjusting forming pressure to make the coil insulating layer about 2.5mm. thick after the forming.
