摘要： PURPOSE:To prevent frictional heat due to vibration from developing between a superconductive coil and an inner case by constructing the superconductive coil in such a way that the inner case is held only by the outer surface of the superconductive coil with a gap between the other three surfaces of the superconductive coil and the inner case. CONSTITUTION:A superconductive coil 1 having a rectangular cross section comprises an outer section 1a, side section 1b, and an inner section 1c, and an inner case 2 housing the superconductive coil 1 comprises an outer plate 2, a side plate 2b, and an inner plate 2c. A support member 10 interposed between the outer section 1a of the superconductive coil 1 and the outer plate 2a of the inner case 2 is fixed to the outer section 1a of the superconductive coil 1 with an adhesive or the like. In this construction, the superconductive coil 1 and the inner case 2 act as one unit by way of the outer plate 2a as a result of a force W in a radial direction generated at the time of excitation and a frictional force caused by the force. Accordingly, the generation of friction between the superconductive coil and the inner case is prevented and the cooling of the superconductive oil is facilitated.

摘要： PROBLEM TO BE SOLVED: To make electric current distribution in paralleled superconductive wires uniform by selecting one or a plurality of element wires from respective element wire bundles of multiple stranded superconductive conductor, connecting the selected element wires with one element wire bundle of another multiple stranded superconductive conductor, and displacing the selected element wires. SOLUTION: In this superconductive apparatus, one superconductive element wire 9 is selected respectively from superconductive strand bundles 10a-1, 10a-2, 10a-3 of 3×3 double-stranded superconductor 15a and replaced by joining each of the selected wires with one of superconductive strand bundle 10b-1 of another double-stranded superconductor 15b. Consequently, since the magnetic bonding between superconductive strands 9, which are magnetically firmly bonded in the same superconductive strand bundle, is lowered, unbalance of electric current distribution due to stranding disorder is hardly caused. Moreover, as compared with a method using a conventional electric resistance, no heat is generated based on Joule's law, so that consumption of liquid helium can be lowered.

摘要： PURPOSE:To always maintain the degree of vacuum high at a part of a device, through which an electron beam passes, and stabilize the degree of vacuum by providing a joint, which is provided with a vacuum vessel, in a beam chamber, and forming an opening part in the vacuum chamber to separate the vacuum vessel and a vacuum space inside of the beam chamber. CONSTITUTION:A vacuum vessel 5 is vacuum-exhausted to a predetermined degree of vacuum to obtain the degree of vacuum required for heat insulation of a low- temperature part. Liquid helium is supplied to a superconductive coil 1 from a liquid helium reservoir 34 through helium pipelines A35, B36, and cooled to a predetermined temperature, and the coil 1 is excited by an external exciting power source to generate a predetermined magnetic field. Charged particles pass through a beam chamber 26, and a flange joint provided with a vacuum seal is provided in the vacuum vessel 5 as a part, in which the chamber 26 passes through the vacuum vessel 5, and opening is formed. A vacuum space of the vacuum vessel 5 and a vacuum space inside of the beam chamber 26 are thereby separated from each other, and even in the case where the degree of vacuum of the vacuum vessel 5 is deteriorated, vacuum of the chamber 26 is maintained at a predetermined degree of vacuum without receiving the influence to obtain the stabilized electron beam for a long time.

摘要： PROBLEM TO BE SOLVED: To easily unify the current distribution of superconductive strands and reduce the consumption of liquid helium by applying bending distortion to the superconductive strands of the prescribed length at the end section of a wound superconductive multi- core conductor to alter them, dispersedly arranging them into a nearly cylindrical shape, and providing a uniformity segment thermally insulating between the strands and reducing the superconductivity critical current apart from the wound portion. SOLUTION: A uniformity segment 10A is arranged at the position having little thermal effect apart from the wound portion of a superconductive multi-core conductor 10 wound on a superconductive electric device, and the critical current of multiple loosened superconductive strands 11 is reduced via the application of a mechanical stress. The strands 11 having large strand currents reach the critical current of the uniformity segment 10A in sequence, ordinary conductive resistance is generated to limit the current, and the current distribution of the superconductive strands 11 is balanced and stabilized. The superconductive strands 11 at the uniformity section 10A in a cooling medium are dispersedly arranged into a cylindrical shape, they give to thermal effect to each other, the temperature rise is accelerated by the boiling of the cooling medium due to heating, and the heat quantity is suppressed.

摘要： PROBLEM TO BE SOLVED: To enable a magnetic field displaying device to easily and surely display the presence/absence of a magnetic field. SOLUTION: A magnetic field displaying device is provided with a moving body composed of a magnetic material 1 which can be moved by a magnetic force and is constituted to display the movement of the moving body as the presence/absence of a magnetic field 103. The moving body is constituted so that the body can be moved by the relation between a spring force or the gravitational force and the magnetic force. The moving body rotationally moves around a rotating shaft along a display window between a position close to the display window and another point far from the window. A container 2 is constituted so that the volume of the container 2 can change as the moving body moves and has a displaying section communicated with the container 2 and contains a liquid enclosed in the container 2. The presence/absence of a magnetic field is displayed by the presence/absence of the liquid in the displaying section caused by the movement of the liquid which moves as the volume of the container 2 changes.
