摘要： PURPOSE:To improve the superconductive property by mixing an activated carbon powder to which plenty of O2 is absorbed to several kinds of powders including elements to compose an oxide type compound superconductor, filling the mixture in a metal pipe to make into a wire material, and heat-treating the resultant wire material in O2. CONSTITUTION:One of oxide powder including Y, Er, Dy, Sm, Gd, Ho, Nd, Yb, Tm, or Lu, one of powder of BaCO3 or BaO, and CuO powder are mixed, and moreover, an activated carbon powder including plenty of O2 is mixed 0.5 to 5wt.%. The particle diameter of the powder is made less than 1mum. The mixture is filled in a steel pipe and sealed, and then forged and wiredrawn to make a wire material with the form of a desired electric circuit element. Then, by applying a heat treatment at 850 to 950 deg.C for 24 hours or more, the O2 absorbed in the activated carbon is released to promote the production of the compound superconductor, and an oxide type compound superconductive wire with a critical temperature of the liquid nitrogen temperature or higher, and a high critical current density can be obtained.

摘要： PURPOSE: To improve a sealability by embedding a heater in a rubber packing used to seal an equipment used during a cryogenic temperature, thereby preventing curing of the packing, adherence of vapor condensation or craze. CONSTITUTION: Since a heater material 2 is embedded in a rubber packing 1 used for an equipment during a cryogenic temperature and energized to prevent curing of the overall packing 1, its hermetical seal is completed and no leakage occurs from the packing. And, thus, adherence of vapor condensation or craze does not occur on a surface of the packing at all due to cold air. Here, the material 2 arranged in an O-ring of the packing is formed in a zigzag manner, thereby sufficiently adopting a heating part.

摘要： PURPOSE:To prevent burnout of a superconductive coil by a method wherein an image of the superconductive coil is transmitted outside a cryostat using a picture transmitter and a transmitted picture is judged by a picture processing device. CONSTITUTION:Light introduced through each light-guide 12a-12c projects to a supervised section which is equipped on a surface of a superconductive coil 2. The image irradiated by this lighting is introduced to a picture processing device 20 through the image-guide 13a-13c respectively. If the quenching is going to occur in accordance with the rise of temperature, bubble of He is generated nearby the surface of the coil 2 or deformation of the coil 2 is started. If such a phenomenon occurs, the transmitted picture signal turns to be different with a reference signal. Thereby, difference between picture signals is caused and output signal S1 from the device 20 is transmitted. If this signal is transmit ted, a switching main body 5 is changeovered to the state of OFF and energy stored in the coil 2 is released.
