摘要： PURPOSE:To obtain a flywheel having a big capacity which has never been obtained in prior art in case there exists a size limit such as a transportation limit or the like by making a revolving body to have a configuration such that a circular disk is cut by parallel symmetrical lines. CONSTITUTION:In case an outer diameter D of a revolving body of a flywheel is exceeding a limit width L of a transportation limit, the revolving body is formed to have a configuration such that it is cut by parallel lines located at distances of L/2 from an axle center respectively. Here, the width L between straight lines is L= Dcos. Consequently, if theta equal 45 deg., the width L becomes about 70% of the diameter D, therefore, ample energy of inertia may be obtained in the flywheel in spite of the existing transportation limit thereon.

摘要： PURPOSE:To obtain a superconducting magnet apparatus wherein the increase of a thermal load is reduced, and the deformation of a thermal shielding board at the time of quenching can be prevented, by arranging scattered recesses on a metal thin board having high resistivity and Young's modulus, and constituting a continuous cavity by combining a flat board having an edge. CONSTITUTION:On the outside of an inner vessel 7 accommodating a superconducting coil 8, a stainless steel board 16 having high resistivity and Young's modulus wherein many convex-shaped recesses are arranged by embossing and a flat board 17 wherein an edge is formed by bending the outer periphery are combined. The recesses are subjected to spot welding and the peripheral edge is subjected to TIG welding, thereby constituting an unified body. Hence a radiant heat shielding board 20 wherein a thermal shielding board 19 having a continuous cavity 18 surrounding many recesses is combined with a conventional thermal shielding board 12 is constituted. Thereby the rigidity of a superconducting magnet apparatus is increased, the induced current is reduced, and the increase of a thermal load due to Joule's heat of the inner vessel can be restrained to a minium, so that the deformation of thermal shielding is restrained and the superconducting magnet apparatus can be stabilized when quenching is generated.

摘要： PURPOSE:To increase the discharge speed of the cryopump in the caption by reflecting gas molecules which comes straight from an opening toward the cryopump unit side by means of a reflection part provided on a sealed plate and having a number of uneven parts. CONSTITUTION:Plural cryopanels 1 are arranged approximately in parallel to the approach direction 5 of gas molecules. Louver blinds 3 are blackened, while a sealed plate 2 which has a reflection part 8 containing number of semi- spherical recesses is arranged on the side of an opening 7. Owing to the reflection part 8, the gas molecules are reflected toward a cryopump unit 6 so that they can reach the surface of the cryopanels 1 easily. Passing probability of gas molecules from the opening 7 is thus improved, resulting in increase of the discharge speed.

摘要： PURPOSE:To reduce an electromagnetic force geuerated between superconducting coils and thereby to lessen the amount of consumption of a cryogenic medium by a construction wherein a vacuum adiabatic container of a superconducting magnet employed in a magnetic resonance imaging apparatus is formed of a magnetic substance except for a part on the diagnostic space side. CONSTITUTION:A vacuum adiabatic container 5 of a superconducting magnet employed in a magnetic resonance imaging apparatus is formed of a magnetic substance except for a part thereof on the diagnostic space side. Concretely, an outer tube 2 and end plates 3 are formed respectively of a magnetic material such as iron, for instance. Then an electromagnetic attracting force 13 acts between a superconducting coil 7 and the outer tube 2 and the end plate 3, and an electromagnetic attracting force 14 generated between superconducting coils 6 is reduced in comparison with the one in a conventional apparatus. Therefore the cross-sectional area of a support 10 supporting the coils is reduced and consequently the amount of consumption of a cryogenic medium is lessened.

摘要： PROBLEM TO BE SOLVED: To provide a superconducting magnet, where a multilayered thermal insulation material in which a mesh-like sheet member is inserted is rigidly fixed to a heat-shielding board, while not causing shielding effect with respect to radiation heat to be reduced. SOLUTION: Related to amultilayered heat shielding material 23, a mesh-like sheet member 22 is inserted between aluminum vapor-deposited sheets 19 only at an outside laminated part, with the outermost layer covered with a heat- resistance sheet member 24. According to this configuration, the thickness of a thermal shielding material is thinner than conventional material while seamed as before, fixing strongly to a heat-shield board 12. Damages due to heat at welding of an outer vessel 13 is prevented.

摘要： PURPOSE:To ensure uniform cooling conditions for bipolar electric current leads for superconducting coil by uniformly twisting the multiple +, - enamel- coated copper or aluminum alloy lead wires, inserting them in a pipe, and circulating helium gas in the pipe. CONSTITUTION:Multiple +, - enamel-coated copper or aluminum alloy lead wires are twisted at a short pitch into a single unit and inserted into a pipe to form an electric current lead 5. This is divided into two poles at a low- temperature terminal 53 and electric current is supplied to a superconductive coil 1 within the liquid helium 2. Gas helium is made to flow in a direction indicated by the arrow 7 in order to cool the lead wires. As a result, it is possible to maintain uniform Joule heat generation at both poles and uniform cooling conditions and, at the same time, to balance the electromagnetic force produced by the lead wires within the electric current lead 5, preventing the generation of external electromagnetic force.

摘要： PURPOSE:To allow the nuclear fusion device to measure a radiation dose rate without the influence of a magnetic field by an oxide superconductor in the neighborhood of a superconductivity coil provided near a plasma to supply it with a microcurrent so as to monitor a voltage. CONSTITUTION:Magnetic field coils 6, 7 allow superconductor 2 to be housed in a helium vessel 4 serving as a liquid helium reservoir. An oxide superconductor 10 is housed in the center part of a toroidal magnetic field coil 7 which is greatly affected by neutron irradiation in the helium vessel 4. This superconductor 10 carries microcurrent through terminals 11 to monitor the voltage of terminals 12. Since superconductivity characteristics are deteriorated by neutrons, a neutron radiation dose rate can be monitored. Since the oxide superconductor has a high magnetic field, it is not affected by the magnetic field which the coils generate.
