    摘要: A pump housing supporting a driving shaft has a plurality of cylinder bores extending radially and arranged at substantially regular intervals around an outer periphery of the driving shaft. Each cylinder bore has a plunger fitted therein, which reciprocates in response to a rotation of the driving shaft. An inlet, an inlet valve, an outlet, and an outlet valve are provided for each plunger. Fluid flowing from an inlet port provided in the pump housing flows into each inlet, and moreover, fluid flowing from each outlet passes through an outlet passage and flows into an outlet port provided in the pump housing. The outlet passage has a plurality of communication holes corresponding to the outlet valves. Outlet ends of the communication holes converge on one spot in the pump housing.

    摘要: In a hydraulic joint structure for joining respective tubular joint portions of two members, opposed pressure-contact surfaces of the two members for preventing loosening form a downstream space on the downstream side of a seal member. A passage is formed on the pressure-contact surfaces in such a manner that when working fluid leaks from the upstream side of the seal member to the downstream space via a clearance between the seal member and the tubular joint portions, the passage permits the working fluid to flow from the downstream space to an external space in the state in which the pressure-contact surfaces are in pressure contact. The passage is formed in such a manner that the passage extends in a circumferential direction of the thread portions, and communicates at one end with the downstream space and at the other end with the external space.

    摘要: A malfunction detection device of a bellows type accumulator for pressurized fluid includes malfunction judgment unit for judging a malfunction of the bellows type accumulator on the basis of a detection output of the pressure sensor. The malfunction judgement unit judges that the malfunction of the seal member generates when the difference between a peak pressure value appeared before a predetermined time is past after the starting of the pressure increase from a value below a predetermined value in the inlet and outlet port and a stable fluid pressure appeared after the appearance of the peak pressure value is not within a predetermined range and/or when the peak pressure value does not appear before the progress of the predetermined time.

    摘要: An object of the present invention is to provide a substrate plating apparatus capable of performing continuous plating operations within one apparatus without the wafers becoming contaminated after the post-plating process by chemicals used in the plating process and the like. Further object is to provide a substrate plating apparatus capable of forming a plating film of uniform thickness on the plating surface of the wafer, while encouraging bubbles to escape from fine holes or grooves in the substrate surface and deterring particles from depositing on the plated surface. According to the present invention, there is provided a substrate plating apparatus for continuously performing a plating process and post-plating process within the same apparatus, the substrate plating apparatus comprising a contaminated zone within which the plating process is performed; a clean zone within which the post-plating process is performed; and a partition dividing the apparatus into the contaminated zone and the clean zone, wherein each zone is independently ventilated. A substrate plating apparatus for plating a surface of a substrate with a plating solution comprises a plating bath that is hermetically sealed and accommodates the substrate to be plated; and a flow path of the plating solution being formed to be parallel to the surface of the substrate.
