摘要： PURPOSE:To reduce a structure vibration due to an earthquake or the like by arranging a plurality of air spring devices made of movable steel tubes sealing the high pressure air on a structure and the foundation thereof in a horizontal direction, and stacking a plurality of the devices in a vertical direction. CONSTITUTION:The horizontal vibration component of a structure foundation due to an earthquake or the like is prevented from being transmitted to a structure by the help of the shearing deformation of a laminated rubber body 4 having restitutive force. On the other hand, the vertical vibration component of the foundation is prevented from being transmitted to the structure, using stacked air spring devices 5 made of movable metal tubes 6. Furthermore, each tube 6 is internally connected to an auxiliary tank via a valve 42 having orifice function, and the vertical vibration component is attenuated with the travel resistance of the air flowing through the valve 42. In this case, if the internal pressure of the tube 6 drops below a preset value, due to an air leakage or the like, a compressor is operated to maintain the pressure at the value.

摘要： PURPOSE:To reduce a structure vibration due to an earthquake or the like by coping with the requirement of three-dimensional base isolation, while a horizontal vibration being reduced with a stacked rubber body and a vertical vibration with an air spring device having pressure resistant movable bellows. CONSTITUTION:The horizontal vibration component of a structure foundation due to an earthquake or the like is prevented from being transmitted to a structure by the help of the shearing deformation of a laminated rubber body 4 having restitutive force or lead 26. On the other hand, the vertical vibration component of the foundation is prevented from being transmitted to the structure by using an air spring device 5 having a high pressure air chambers 6 and 7 formed out of inner and outer movable bellows 14 and 15. In addition, the chambers 6 and 7 are communicated with an auxiliary tank through each valve and the vertical vibration component is attenuated with the travel resistance of the air flowing through the valve. In this case, if the internal pressure of the chambers 6 and 7 drops below the preset value, a compressor is operated to maintain the internal pressure at the value.

摘要： PURPOSE: To obtain a measuring method in which the cross-linking progress state of an uncross-linked rubber can be measured by a method wherein one pair of specific steels plates out of a plurality of internal steel plates which support uncross-linked laminated rubber are used as electrodes, a cycle voltage is applied and an electrical characteristic value is detected. CONSTITUTION: Sheetlike unvulcanized rubber and steel plates 14 to 18 are arranged alternately inside a mold 20 which has been preheated to the vulcanizing temperature of the rubbers, and an axial-direction load is applied to the sheetlike unvulcanized rubber and the steel plates 14 to 18 by an upper plate 41 and a push plate 43 by means of a press machine 50. The laminated rubber 13 which are arranged in the mold 20 raise their temperature with the passage of time so as to reach the vulcanizing temperature, of the rubber, which is the same temperature as the mold. Thereby, as the cross-linking reaction of the laminated rubbers 13 progresses, an electrical AC resistance value is raised once, it is then lowered, and it then displays a constant value. This indicates a point of time in which the time change rate of an AC resistance becomes nearly zero, and it is a point of time in which the cross- linking reaction of the laminated rubber 13 has been completed. Consequently, when a change in the time change rate of the electrical AC resistance is traced, the progress degree of the cross-linking reaction of the rubber can be observed.

摘要： PURPOSE:To positively the degree of deterioration of a rubber body even if no dimensional change occurs together by judging the electrical impedance of the rubber body. CONSTITUTION:A rubber support 10 is provided with disc-shaped upper and lower flange plates 11 and 12, a cylindrical rubber body 13, and internal steel plates 14-16 for reinforcement which are buried into the rubber body 13. A specific and uniform static compression force is applied in the direction of an arrow B and at the same time a voltage with a specific frequency is applied between the steel plates 14 and 15 simultaneously. The vertical displacement generated at the rubber body and impedance change between the steel plates 14 and 15 are detected. The internal strain of the rubber body 13 is detected from the change in the impedance of the rubber body 13 and the number of changes in impedance is integrated, thus determining the degree of deterioration of the rubber body 13 caused by the generation of internal strain.

摘要： PURPOSE:To make a second heat exchanger small in size by a method wherein a heat generated by a heat generating source operated intermittently is accumulated in a first heat exchanger and the accumulated heat is released outside gradually by the second heat exchanger. CONSTITUTION:When a heat generating source 19 operated intermittently, such as a nuclear fusion reactor, works for a short time, a primary coolant circulating through a primary fluid loop 27 is heated with absorption of a heat of the heat generating source 19. In a first heat exchanger 24, heat exchange is made between the primary coolant and a secondary coolant being present inside the main body 20 of the heat exchanger and the heat generated by the heat generating source 19 is accumulated in the secondary coolant. In a second heat exchanger 29, the heat exchange is made between the secondary coolant flowing through a secondary fluid loop 32 and seawater flowing through a tertiary fluid line 36 and the secondary coolant is cooled down. Since the main body 21 of the second heat exchanger has a smaller capacity for filling the coolant than the main body 20 of the first heat exchanger, the heat exchange between the secondary coolant and the seawater is not wholly completed during the working of the heat generating source 19 and, therefore, the operation is continued.

摘要： PURPOSE:To realize the use under a severe environment at high temperatures and of large radiation quantity and provide remarkably excellent super heat resistance and radiation resistance by covering a conductor with a mica tape, and forming a second insulating layer on the obtained first insulating layer. CONSTITUTION:A conductor 1 is covered with a mica tape, thus obtaining a first insulating layer 2, which is covered with a tape made of Si-N-O continuous fiber having an oxide concentration of 0.1-2.0wt.% and infused by ionizing radiation, thereby providing a second insulating layer 3. The Si-N-O continuous fiber is such constituted that a ceramic precursor polymer such as polycarbosilane or polysilazane is turned into fiber, followed by ionizing radiation at 6-10MGy radiation quantity in an inactive gas atmosphere, to be sintered at 700-1200 deg.C in gas having a nitriding effect. Consequently, it is possible to provide remarkably excellent super heat resistance and radiation resistance, and realize the use under a severe environment of high temperature of 1,000 deg.C or higher and quantity of 100MGy or higher.
