摘要： PURPOSE:To shorten the measuring time for continuous heat generation without making a calorimeter larger in size by taking into account the plumbing method for the calorimeter. CONSTITUTION:In prior to the following heat generation measurement after the preceding measurement has been completed, the water in an inner tank is completely removed practically and then a specified amount of water whose temperature is lower than the set temperature is fed into an outer tank 14. Further, after the temperature in the outer tank became approximately same as the set temperature, a part of water in the outer tank is fed into the inner tank 12, thereby shortening the time necessary for removing/ feeding water in the inner and outer tanks and adjusting the set temperatures therein and reducing total measuring time.

摘要： PURPOSE:To relax a thermal shock and prevent a damage and degradation of characteristic even if an oxide superconductive compound material having a multilayer perovskite structure is dipped in liquid nitrogen by coating the periphery of the oxide superconductive compound material with a coating layer which satisfies a specified condition. CONSTITUTION:The periphery of an oxide superconductive conductor 11 composed of Y-Ba-Cu-O group compound and having the perovskite structure is coated with silicone rubber 12 at the predetermined thickness under the condition that the interface with the peripheral surface is free. Furthermore, the periphery of the rubber 12 is packed with the aluminium material 13 to form an oxide superconductive compound material. The coating layer 12 made of the silicone rubber 12 has airtight property and non-permeability, and the relation of thermal conductivity at a room temperature and the mean thickness of the coating layer 12 satisfies a formula I. Furthermore, since the conductor 11 and the layer 12 are not jointed, they are not constrained mutually against the thermal strinkage. Even if the compound material is dipped in liquid nitrogen, the thermal shock is relaxed to prevent the damage and degradation of characteristic. In the formula, the unit of the mean thickness is cm, and the unit of the thermal conductivity is cal/cm.sec deg.C.
