    • PROBLEM TO BE SOLVED: To provide a manufacturing method for biodegradable fiber-reinforced plastics composed of a combination of cellulose fiber and polylactic acid requiring a kneading process and without deterioration.
      SOLUTION: This method is for manufacturing the biodegradable fiber-reinforced plastics composed of the cellulose fiber bonded with the polylactic acid. The method comprises a process of compression-molding the cellulose fiber into a fiber consolidated material; a process of cutting the fibrous consolidated material into fibrous consolidated pellets; a process of mixing the fibrous consolidated pellets with polylactic acid pellets; and a process of molding the obtained pellet mixture at a higher than a meting point of the polylactic acid.

    • PURPOSE: To make the electromagnetic force of a superconducting magnet uniform by a superconducting shield and to prevent the deviation between wire materials for constituting the magnet by differentiating the distance between the shield and the magnet at the end the intermediate part of the magnet. CONSTITUTION: A substantially spherical superconducting shield 9 is disposed so as to surround the periphery of a superconducting magnetic 2, and the generated magnetic field is requlated by the shield 9. The upper and lower ends of the magnet 2 are oblique at the shield 9, and close to the magnet 2. Accordingly, when the center is '1', the electromagnetic forces of the upper and lower ends become 0.8 or more and the forces are made uniform. Thus, a uniform electromagnetic force operates on the coil for forming the magnet 2, the friction by the relative movement between superconducting wire materials for forming the coil can be reduced, thereby preventing the quench caused by it.

    • PURPOSE:To provide a persistent current switch in which the quenching is suppressed under superconducting state while sustaining a high resistance when a supeconducting switch is turned OFF. CONSTITUTION:The persistent current switch 21 comprises a supeconducting coil 32 wound around a cylindrical housing 31 to constitute a supeconducting switch, and fixed and movable cores 33, 34 disposed in the housing 31 and constituting a mechanical switch. The cores 33, 34 are applied with fixed coil 35 and a movable coil 37 wherein both the superconducting and mechanical switches are turned OFF when two coils are not excited and turned ON when two coils are excited. OFF resistance can be increased by reducing the stabilizing material for the superconducting coil 32 constituting the superconducting switch and quenching can be suppressed under a state where the persistent current switch is turned ON by forming a bypath by means of the mechanical switch.

    • PURPOSE: To provide a magnetic shielding apparatus capable of normally conductively transferring by friction of eddy current and electromagnetic force without reducing the shielding effect even if an exciting speed is large. CONSTITUTION: A good conductor 12 is provided between a superconducting magnetic shield 14 for preventing the external leakage of a magnetic field generated from a superconducting magnet 10 and the magnet 10. An eddy current of the direction for cancelling the magnetic field generated from the magnet 10 flows to the conductor 12 to alleviate the change of the magnetic field applied to the shield 14. The conductor 12 and the shield 14 are thermally and electrically insulated, and the part or all of the shield 14 is prevented from being normally conductively transferred by the friction generated between the conductor 12 and the shield 14 by the heat or electromagnetic force generated by the eddy current flowing to the conductor 12.
