摘要： PROBLEM TO BE SOLVED: To sufficiently shorten the most shrunken length irrespective of a long stroke, while accomplishing a sufficient shock absorbing function, by taking a long stroke with plural cylinder structures. SOLUTION: In the case where the shock absorber is extended from the most shrunken state, a cylinder device 37 is extended. However, at this time, the second cylinder 37 is drawn out from the third cylinder 22 in an upward direction. Hydraulic oil in an upper part oil chamber 23 is sent to the second lower oil chamber 19 of the second cylinder through the third through-hole 25. Consequently, the oil pressure in the lower oil chamber 19 is heightened, and the second piston is pushed upward, and the first cylinder 11 is drawn out from the inside of the second cylinder 17. By this operation, the oil pressure in the second upper oil chamber 18 is heightened, and the hydraulic oil in the second upper part oil chamber 18 is sent to the first lower part oil chamber 15 through the second through hole 20. As a consequence, the first piston 13 is raised in the first cylinder 11 to push the rod 12 upward.

摘要： PROBLEM TO BE SOLVED: To provide vibration damping devices easy to fabricate and construct, capable of absorbing and damping the horizontal shaking of a plurality of adjacent high-rise structures by working in combination. SOLUTION: This vibration damping device includes a single-rod-type load cylinder 2 connecting the tops of high-rise structures together and a single-rod- type oil quantity correcting cylinder 7 having a larger diameter and a smaller stroke than the load cylinder 2. The head side oil chambers 10, 12 and the rod side oil chambers 11, 13 of the cylinders 2, 7 are communicated with each other through valve modules 14, 15 in which fixed diaphragms 18, 19 equipped with check valves 16, 17 working on the flow of hydraulic fluid from the former oil chamber to the latter oil chamber are arranged parallel to relief valves 20, 21. The inside of the piston rod 9 of the oil quantity correcting cylinder 7 is hollowed to form a reservoir 22 for supplementing the hydraulic fluid for leakage and for compensating volumetric changes. The reservoir 22 is communicated with the head and rod side oil chambers 12, 13 of the oil quantity correcting cylinder 7 through a valve module 23 comprising a relieve valve 28 equipped with check valves 24, 25 and 26, 27 on each side.

摘要： PROBLEM TO BE SOLVED: To provide degrees of freedom for axial sliding movement of a wheel, in a bearing device supporting the wheel rolling on a rail. SOLUTION: Shaft holes are coaxially formed in a pair of oppositely arranged brackets 20 respetuvely. A wheel shaft 24 is supported in the shaft holes so as to slide in the axial direction through bushes 23a, 23b. An antifriction bearing 25 is fixed on the wheel shaft between the brackets 20. A wheel 26 is fitted to the outer periphery of the bearing thereof and a specified clearance allowing the wheel shaft 24 to slide is set between the wheel and the brackets 20 arranged opposite to both faces thereof.
