CONSTITUTION:In a connection part of a helical coil container 14 divided into a plurality of parts in the winding direction, there are provided a fitting 12 structure and a key 11 structure formed with desired accuracy in a helical groove of a discharge tube. After the key 11 is inserted and connected by bolts 13, the connection is formed by being covered with a sealing film 15 from the inside of the container 14. Thus, the container 14 spaced from the discharge tube can be easily obtained with high accuracy. Also, a coil is wound around the container groove and a lid 16 of the container 14 is mounted with bolts 17 having a seal cap 18. Then, when the contact surfaces of the container 14 and lid 16 are seal welded 19 in the winding direction, stable plasma enclosure is provided and a helical coil holding air-tightness is obtained. Further, when another seal structure 20 is provided outside the container 14, only repair spots can be repaired from the outside after assembling of the coil without disassembly.

摘要： PURPOSE:To improve mechanical impact resistant and to reduce permeation of a gas molecule by a method wherein an electric insulating coupling is formed by composite structure of FRP and a metallic pipe or ceramics. CONSTITUTION:Fluid flowing through a metallic duct 1 flows through an FRP cylinder 6. In this case, the metallic ducts are electrically insulated by means of the FRP cylinder 6, and a gas molecule is fluid is shielded by a metallic pipe 7 embedded in the FRP cylinder 6 and prevented from leakage to the outside. Since an electric insulating coupling is formed by composite structure of FRP and a metallic pipe or ceramics, this constitution provides a coupling which improves mechanical impact resistance, reduces permeation of a gas molecule, and has excellent performance.

摘要： PURPOSE: To obtain a superconductive coil quench detecting device which is less affected by magnetic noises so as to accurately detect a very low voltage induced with quench of a superconductive coil. CONSTITUTION: When a quench occurs in a superconductive coil 2 inside a vacuum thermally insulated vessel 3, a voltage is generated in the superconductive coil 2, but no voltage is generated in pickup coils 4a and 4b provided adjacent to the superconductive coil 2, a quench detector 5 judges that a quench occurs in the superconductive coil 2 basing on a voltage generated in the coil 2, a power supply 1 is shut off by a circuit breaker 9, and a protective resistor introducing switch 10 is turned on so as to make a discharge take place through a protective resistor 11. If magnetic noises are introduced from outside, a voltage generated in the superconductive coil 2 is canceled out with a voltage generated by the pickup coils 4a and 4b, so that a quench detector 5 is not actuated and protected against the effect of magnetic noises.

摘要： PROBLEM TO BE SOLVED: To provide a single crystal production apparatus capable of impressing a radial cusped magnetic field of coaxial symmetry to the neighborhood of the center of a fusion of crystal material inside a crucible in a crystal pulling section to improve crystal properties by the use of a magnetic field generator for impressing a magnetic field into the fusion of crystal material. SOLUTION: This single crystal production apparatus comprises a single-crystal pulling section and a magnetic field generator section for providing a magnetic field for a fusion section for a single crystal material in such a configuration that on both sides of the crystal pulling section a pair of main coils and a pair of subsidiary coils which have a smaller diameter than that of the main coils and whose exciting direction is coaxial and opposite to the main coils. In this configuration of the single crystal production apparatus of magnetic field impression type shown in the figure, a crucible 2 filled with a single crystal fusion material 1 is heated by a heater 3 so as to be maintained constantly in fused condition. A seed crystal 4 is pulled up at a constant speed. The superconductive main coils 21a and subsidiary coils 21b generates a magnetic field in vertical direction as shown by the direction of field impression 11 in the crucible 2. As a result, the heat convection 8 induced by the heater 3 is substantially controlled by magnetic resistance caused by the magnetic field in the vertical direction.
