摘要： PROBLEM TO BE SOLVED: To provide a seismic isolation/vibration control device in the horizontal direction using superconductors. SOLUTION: A three-layer structured lowermost layer of the seismic isolation/vibration control device is configured having permanent magnet rows 212A, 212B disposed on steel plates 210A, 210B vertically installed on supporting bases 214A, 214B. The superconductors 222A, 222B are disposed inside a low-temperature container 220 opposing the permanent magnet rows 212A, 212B. Further, on the upper surface of the low-temperature container, a permanent magnet row 226 is disposed on a steel sheet 224. This is the structure of an intermediate layer of the seismic isolation/vibration control device including the structure of the interior and the upper surface of the low-temperature container. A superconductor 232 is disposed in the low-temperature container 230 on the intermediate layer opposing the permanent magnet row 226. This is the structure of an uppermost layer. Surfaces of the permanent magnet rows and the superconductors facing with each other on a lowermost layer to the intermediate layer are disposed in the vertical direction, and opposed in the horizontal direction (radial type). A levitation force is designed to be obtained from magnetic stiffness between the facing permanent magnet rows and the superconductors. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PURPOSE:To provide an oil damper for suppressing the variation of the resistance force for the variation of the relative speed between a piston and a cylinder. CONSTITUTION:In the passages 8 and 9 on a piston rod 3 side, relief valves 10 and 11 having each different opening working pressure and solenoid valves 12 and 13 for loading or unloading the relief valves 10 and 11 by the opening and closing are installed. The relief valves 10 and 11 are closed when each hydraulic pressure in the passages 8 and 9 is below an opening working pressure, and the relief valves 10 and 11 are opened when each hydraulic pressure in the passages 8 and 9 is over the opening working pressure, and the opening degree is automatically adjusted so that the hydraulic pressure is kept nearly at the opening working pressure. The variation of the resistance force for the variation of the relative speed between a piston 2 and the cylinder 1 is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a base isolated table for exhibition, which can be handled easily by making it unnecessary to adjust a friction damping function in accordance with the weight of an exhibit to be placed on the table by providing a support function, restoration function and damping function in a lump. SOLUTION: In this base isolated table for exhibition, at least three base isolated devices 4 comprising a pair of supporting bases 6A and 6B and rollers 7, which are arranged between the supporting bases 6A and 6B, are interposed between a pivotable base table and a pedestal, on which an exhibit is placed. In addition, the supporting bases 6A and 6B of the base isolated devices 4 comprise groove shaped rails 10, which are formed by two inclined faces 9, which are arranged intersected each other in the rolling direction equipped on at least one side and the groove width of the groove shaped rails 10 formed narrower toward both end sections from the center section keeping their inclination angle constant, and the rollers 7 comprising at least one inclined face 15, which is made to abut on the inclined faces 9 of the groove shaped rails 10, is arranged keeping a clearance between the rollers 7 and the groove bottoms 14 of the rails 10 constant.

摘要： PURPOSE:To provide a damping device that is equipped with a damper unit capable of easily setting an almost constant specified damping force. CONSTITUTION:A controller controls the opening or closing of solenoid valves 12, 13 and thereby two relief valves 10, 11 installed in oil passages 8, 9 of an oil damper 55 of a damper unit are loaded or unloaded, selecting the extent of damping force in the damper unit. These relief valves 10, 11 operates its opening when each pressure of oil in the oil passages 8, 9 is reached to an open working pressure, and opening is automatically regulated so as to keep the oil pressure almost in the open working pressure. Therefore, even if a relative speed between a cylinder 1 and a piston 2 is varied to some extent, hydraulic pressure in this cylinder 1 comes almost to a constant. Accordingly, an almost constant specified damping force that is almost independent of the relative speed between the piston 2 and the cylinder 1 is easily maintainable.
