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 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.

SOLUTION: A moving end section 1 which moves straightly against a case 3 and a rotary shaft 2 journaled turnable in the case and having discs 23 concentricly fixed on the shaft are provided. The moving end and the rotary shaft part are connected through motion conversion systems 15 and 21 which convert a straight motion of the moving end into a rotative motion of the rotation shaft. The discs of the rotary shaft part consist of induction current materials, and the case contains magnets 37 deployed closely to the discs in a way that different magnet poles are deployed on both of the discs' sides. Also, it is possible that the magnets 37 are incorporated into the discs and a plate made of induction materials is attached to the case, instead.

摘要： PROBLEM TO BE SOLVED: To sufficiently absorb the vertical vibration components of the base of a building, making their transferring to the building hard by providing a metal balloon which is made of thin-walled super-plastic material and is formed into a bellows shape, wherein ridges and valleys having U-like cross sections alternately continue, and at each center of the upper and lower end face of which cylinders are concentrically and continuously formed. SOLUTION: In the outer circumference of the bellows section of a metal balloon 10, that is, in each valley 12, a reinforcing ring 14, whose inner side is made after the shape of the valley 12 and the upper and lower faces on the outer circumference are made after the shape of a ridge 11, is secured. An upper seat 15 is secured at the upper end of the metal balloon 10, and a lower seat 15' is secured to the lower end. The vertical vibration components of the base of a building, based on crystal movements such as earthquake are absorbed by the expansion and contraction of the metal balloon 10 of an air spring device 16, making their transferring to the building hard. Even if they are transferred to the building, they are substantially damped.

摘要： PROBLEM TO BE SOLVED: To perform a high cycle test using a shaker of low shaking force and to test a test piece while controlling constant displacement and constant load by utilizing the vibration characteristics of a vibration system employing the test piece and a dynamoelectric shaker as a spring and a mass. SOLUTION: A dynamoelectric shaker 2 is set on a lower fixing floor 1 in the center thereof and posts 3 at stood on the opposite side thereof. An upper fixing floor 4 is secured to the upper part of the post 3 and a test piece upper fixing jig 5 is secured to the lower surface thereof. A test piece P having one end secured to the jig 5 and the other end secured to a test piece lower fixing jig 11 is then mounted on a shaking table 10. When the shaker 2 is operated to apply a shaking force to the test piece P, the test load is increased significantly utilizing the vibration characteristics of a vibration system employing the test piece P and the shaking table 10 as a spring and a mass. In other words, a high cycle fatigue test can be performed using a shaker of low shaking force. Furthermore, since the test piece P is fixed at one end, fatigue test can be performed while controlling constant displacement and constant load appropriately.

摘要： PURPOSE:To eliminate the need for bellows and maintenance by supporting a high temperature piping or duct by a rod-type support in such way that the high temperature piping or duct can be tilted to angles at which its movement in a plane perpendicular to the heat transfer direction is restricted and it can oscillate forth and back in the heat transferring direction. CONSTITUTION:With a rod-type support 21, screw bolts 17 having pin receivers 16 are adjustably screwed into both end parts of a rod 15. Supporting fittings 19 are connected through pins 20 to the pin receivers 16 of both end parts. A pair of red-type supports 21 are mounted as one set so that a high temperature piping 22 can be tilted to angles at which its movement can be restricted in a plane F perpendicular to the longitudinal direction shown by the arrow indicating heat transfer of the high temperature piping 22, and it can oscillate forth and back in the heat transferring direction. As a result, impact force of earthquake, etc., and dead load can be positively supported. Further, heat transmission can be released, the piping can freely expand, and no bellows is required.
