摘要： PROBLEM TO BE SOLVED: To provide a top ring capable of maintaining a force for raising a chuck base high even when the chuck base is lower than a reference value. SOLUTION: A rubber plate 14 is held under a condition that a predetermined tension is held by combining a rubber plate 14, whose outer periphery is nipped between a tubular edge 8 of a top ring 7 and a bottom ring 9, and a plate spring member 13 made of a disc-like metallic plate and having an outer periphery smaller than an inner periphery of the tubular edge 8 and an outer periphery approximately same as an inner periphery of the top ring 7. When a chuck base 21 is lowered, the plate spring 13 arranged on the rubber plate 14 is also flexed according to a shape of the rubber plate 14, so that a reaction force is applied in a direction for raising the chuck base 21 by an elastic force of the rubber plate 14 and an elastic force of the plate spring member 13.

摘要： PROBLEM TO BE SOLVED: To synchronize the revolving time of a revolving upper structure and extent of the boom elevation during the revolving time in a hydraulic shovel which employs a hydraulic circuit comprising an independent boom circuit.SOLUTION: On a hydraulic shovel, a hydraulic cylinder moves a boom by use of the oil delivered from a first hydraulic pump. A first hydraulic circuit connects the first hydraulic pump and the hydraulic cylinder, forming a closed circuit between the first hydraulic pump and the hydraulic cylinder. A hydraulic motor turns a revolving upper structure by use of the oil delivered from a second hydraulic pump. The second hydraulic circuit is formed independently from the first hydraulic circuit, connecting the second hydraulic pump and the hydraulic motor. A motor-hydraulic-pressure-reducing part reduces the drive hydraulic pressure of the hydraulic motor when designated conditions are met. The designated conditions are that an operation of a boom-control component for raising the boom and an operation of a revolving-operation component for turning the revolving upper structure are performed in parallel, and control input of the boom-control component is equal to or more than a threshold value.

摘要： PROBLEM TO BE SOLVED: To provide a retainer mechanism for improving the flatness of a wafer by uniformizing the pressing of a retainer over the whole outer peripheral part of the wafer. SOLUTION: This retainer mechanism includes: a chuck plate 26 for sucking and fixing the wafer 27; a polishing cloth 5 for polishing the wafer; and a retainer 36 disposed in the periphery of the wafer 27, wherein the retainer 36 is provided to freely rotate independently of the chuck plate 26. Since the relative position in the rotating direction of the retainer 36 is variable to the wafer 27 (the chuck plate 26), the pressing of the retainer 36 is uniformized over the whole outer peripheral part of the wafer 27 so as to improve the flatness of the wafer 27.

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic driving system capable of reducing a loss in power consumption carried out by a charge pump.SOLUTION: An operation state-determining section 24C determines whether a hydraulic cylinder 14 is in operation or is in non-operation. A discharge pressure reducing portion 39 reduces a discharge pressure of a charge pump 28. A discharge pressure control section 24d, when the hydraulic cylinder is in non-operation, controls the discharge pressure reducing portion and reduces a discharge pressure of the charge pump to a low pressure lower than a normal pressure. The normal pressure is the discharge pressure of the charge pump when the hydraulic cylinder is in operation. An accumulator 38 is connected to a charge flow channel 35. A one-way valve is arranged between the accumulator and the charge pump. The one-way valve 49 allows a flow of actuation oil from the charge pump to the accumulator and, meanwhile, inhibits the flow of the actuation oil from the accumulator to the charge pump.
