摘要： PURPOSE:To simplify the structure by combining a cylinder made of superconducting material and annular superconducting floats where magnets for producing magnetic field are arranged around the superconducting cylinder. CONSTITUTION:When a cylinder 2 made of superconducting material is erected vertically and coolant 6 having temperature lower than the critical temperature of superconducting material is fed through a coolant inlet/outlet 4 at the lower end, the portion of the superconducting cylinder 2 contacting with the coolant 6 is brought into superconducting condition. When power is fed to a magnet 1 under this condition and flux is produced, flux is confined in the cylinder 2 and rises to non-superconducting portion of the cylinder 2(portion not contacting with the coolant 6) and spreads to the outside of the cylinder 2. When an annular superconductor(containing coolant 6 at the inside) is fitted over the cylinder 2 and moved downward, floating force is produced through repulsion against the flux at the portion where the flux spreads to the outside of the cylinder, and the annular superconductor 5 stops in place. Then the coolant 6 id taken in/out of the cylinder 2 so as to vary the level of coolant 6 thus varying the floating height of the superconductor 5.

摘要： PURPOSE:To make a manufacture easy and to contrive the improvement of reliability by adhering an inner tank made of FRP to an outer tank made of FRP both of which are integrally formed with pressure inserting a glass mat, a glass nonwoven fabric, etc. impregnated with adhesives. CONSTITUTION:Between the flanges 2, 4 of an inner tank 13 and an outer tank 14 both of which are made of FRP, a material 15 placed with a glass fiber such as a glass mat 18, a glass nonwoven fabric 19, etc. impregnated with adhesives at random is provided and the adhesives are hardened by pressing. Since the glass mat 18, the glass nonwoven fabric 19, etc. have no continuous fiber in the radial direction, the effect of the reduction of the transmittance of a gas due to the mixing of glass fiber can be obtained. Even if the inner and the outer flanges have somewhat deformation or roughness, these are absorbed by the elasticity of the glass mat or the glass nonwoven fabric and a highly reliable adhesive structure can be obtained. This enables to obtain a cryostat made of FRP which is easy in manufacture and has good airtightness and high reliability.

摘要： PURPOSE:To prevent the disorder of the superconductive wire and to obtain the uniform magnetic field by a method wherein the superconductive wire is wound around a cylindrical coil bobbin in the axial direction tightly at uniform pitch to be in solenoidal manner and to form a layer, and a surface of the layer is coated with resin to be leveled thereby repeating formation of the predetermined layers. CONSTITUTION:The superconductive wire is wound around a cylindrical coil bobbin 2 in the axial direction tightly at uniform pitch to be solenoidal manner and to form a first layer 4A. When the first layer 4A is formed, its surface is coated with resin 6a to be leveled, after which the winding operation by the similar method is repeated for predetermined times to form a second layer 4B- fourth layer 4C. Also the resin 6 in which inorganic powder 7 is mixed is coated and recesses among the superconductive wires 4 are made to be inorganic substance 7 and the resin 6 is formed in the deeper portion. Viscosity of the resin 6 is increased to facilitate the formation of even planes. Thus the solenoid coil, which prevents disorder of the superconductive wire and offers uniform magnetic field, can be manufactured.
