摘要： PURPOSE:To obtain the solenoid coil in which super-conductive breakdown will be prevented by a method wherein, when a super-conductive coil is manufactured, a fibrous enamel-coated electrically insulated material and conductor, whereon a double coating is performed, are used. CONSTITUTION:Enamel 6, containing epoxy resin as an impregnant, is applied and baked on the surface of a super-conductive conductor 1, and a super-conductive wire rod 7 is formed by winding a fibrous electrically insulated material 2 on the above conductor 1. Then, a super-conductive solenoid coil is formed by winding a plurality of the wire rod 7 in such a manner that they are maintained in a lined up form. Through these procedures, as the enamel 6 is coatd by baking on the super-conductive conductor 1, the adhesive strength between the two materials are high, and also as both enamel 6 and the epoxy resin are organic high molecular compound, their affinity is excellent and the adhesive strength between the enamel 6 and the epoxy resin is high. Accordingly, when tensile stress is applied, no slipping is generated among the conductor 1, the enamel 6 and the electrically insulated material, a rise in temperature is reduced, and no decline of critical value is generated.

摘要： PURPOSE:To reduce the weight of the superconductive magnets and obtain the great suspension force of a superconductive magnetically suspension railway by a method wherein a suspension coil constructed on the ground is divided into right and left side and are arranged symmetrically against the lines of the superconductive magnets loaded and almost vertically arranged on a car. CONSTITUTION:The suspension coils 8 are constructed on a track 4 and the superconductive magnets 7 arranging almost vertically against the coils 8 are provided on a car body 1. The propulsion guide coils 6 are constructed on the track 4 confronting with the superconductive magnets 7, and the car body 1 is propelled by the electromagnetic force generated between the susperconductive magnets 7 and the propulsion guide coils 6. The suspension coils 8 are divided into right and left side and arranged symmetrically against the lines of the superconductive magnets 7, and the body 1 is kept in suspension by the electromagnetic force generated between the superconductive magnets 7 and the suspension coils 8. By this construction, a greater suspension force can be obtained without increasing the number of turns of the suspension coils 8 compared with the case in which the suspension coils 8 are arranged without divided, and thereby the supermagnetic forces of the superconductive magnets 7 do not have to be large and the rolling of the car body 1 can be reduced.

摘要： PURPOSE:To normally operate a rotary electric machine without magnetic shield even in a strong DC magnetic field near a stationary electric device by providing a rotor type armature utilizing a DC magnetic flux generated from the device as a field magnetic flux. CONSTITUTION:A motor 7 is disposed in a magnetic field formed by a superconductive magnet. Since a magnetic field formed of the magnet 1 is, for example, approx. 2-3 kilogauss near the magnet 1 in case of a magnetic levitating train, the magnetic flux density crossing the armature winding of the motor 7 becomes 4-6 kilogauss or higher, and this value can be sufficiently utilized as the field magnetic flux.

摘要： PURPOSE:To prevent the superconductive breakdown of a superconductive coil made of a superconductive coil unit and a spacer by buffing the contact surface of the coil unit with the spacer. CONSTITUTION:The contact surface of a spacer 4 contacted with a superconductive coil unit 1 is buffed. Thus, the superconductive breakdown of a coil caused by the frictional heat due to the relative displacement between the coil unit 1 and the spacer 4 can be prevented.

摘要： PURPOSE:To obtain a super-conductive coil which seldom causes super-conductive breakdown, by constituting with super-conductor insulated with organic macromolecular fiber having great tensile strength. CONSTITUTION:A super-conductive wire 7 consists of a super-conductor 1 and an insulator 6 made of organic macromolecular fiber having over 30kg/mm. of tensile strength to cover the super-conductor 1. A super-conductive coil is manufactured with the use of this super-conductive wire 7. As a result, cracks due to electromagnetic force working on the super-conductive coil are hard to occur to epoxy resin which packs inside the super-conductive coil and penetrates into a fiber insulator 6 with over 30kg/mm. of tensile strength. This prevents the super- conductor 1 from rising in temperature caused thereby. The super-conductive coil keeps super-conductive status up to high current value (less than critical current value).

摘要： PURPOSE:To prevent the generation of super conductive breakdown for the subject coil by a method wherein a low friction material is inserted between a wiring circuit and a spacer. CONSTITUTION:The low friction material 6, for example, such as a kapton film, a tetron film and the like, is inserted between the spacer 4 and the wiring circuit 1. By having this low friction material 6, the heating due to the relative displacement between the wiring circuit 1 and the spacer 4 is reduced, and the generation of the super conductive breakdown can be prevented.

摘要： PURPOSE:To enable to avoid the resonance of a vehicle side with a vibration system without increasing the weight of the vehicle by laying ground coils at irregular pitches. CONSTITUTION:Propulsion coils 2 are laid at an equal pitch to an orbit 1, and floating coils 3 are laid at irregular pitches (L1not equal to L2). In this manner, since the pulsating component of a floating force does not become sinusoidal connection wave of the prescribed frequency even at a constant speed, the resonance with a vibrating system of a vehicle side can be avoided, thereby reducing the vibrating response.

摘要： PURPOSE:To keep the insulation of landside coils to the irreducible minimum by a method wherein an individual coil of a landside coil group is insulated only as demanded by the share of surge voltage it is to bear. CONSTITUTION:The landside coils LSM1-LSM4 collect power from a feeder device 5 or 6 via breakers CB1-CB4 that operate in response to the location of a vehicle 1. Surge voltage generated at the time of feeder 5 or 6 commutation or of circuit breakers CB1-CB4 rupture is fully applied on the first and following several coils of the landside coil group and, caused by the reflection of travelling surge voltage, high voltage is applied upon several coils from the ends. Landside coil manufacturing cost can be reduced by reinforcing insulation of only several landside coils from both ends of the landside coil group.
