    摘要: A turbomachine having an impeller rotating within a casing of the machine and groove passages are formed in a wall of the casing between an upstream portion and a downstream portion of the impeller and high pressure fluid is injected into the groove passages for increasing the stall margin without lowering the peak efficiency of the machine and prevents generation of a positive slope in a head-capacity curve.

    摘要: A switch has a first leaf spring having a first contact, the first contact being formed in a V shape and including two inclined surfaces, a second leaf spring having a second contact facing the first contact, the second contact being formed in a convex shape and including vertexes facing the inclined surfaces, respectively; and a pressing unit that presses the first leaf spring or the second leaf spring. When the pressing unit presses the first leaf spring or the second leaf spring, the inclined surface on a first side of the first contact and the vertex on a first side of the second contact come in contact with each other, and the vertex on the first side of the second contact slides on the inclined surface on the first side of the first contact.

    摘要: Disclosed are a resistance welding method for welding a stack of three or more works and a device therefor. A stack is formed in such that the thinnest work having the smallest thickness among the works is placed in the outermost position. The stack is held between a first welding electrode and a second welding electrode. A pressing member is brought into contact with a location of the thinnest work different from the location with which the first welding electrode is in contact, and the pressing member is caused to press the stack from the thinnest work side. In a state that the pressing force exerted on the stack by the first welding electrode and the pressing member is balanced with the pressing force exerted on the stack by the second welding electrode, current is applied between the first welding electrode and the second welding electrode.

    摘要: A power recovery system is used for reducing the total energy consumption in a process such as an industrial treating process or a fluid refining process including the delivery of a fluid under a high pressure. The power recovery system includes a high-pressure pump for pressuring raw water, a reverse osmosis membrane cartridge for treating high-pressure water discharged from the high-pressure pump with a reverse osmosis membrane to produce treated water, a positive-displacement piston pump for pressuring raw water under the pressure of concentrated water which is discharged from the reverse osmosis membrane cartridge without being treated by the reverse osmosis membrane, and a power recovery pump turbine for boosting the pressurized raw water discharged from the positive-displacement piston pump and adding the boosted water to the high-pressure water discharged from the high-pressure pump. The power recovery pump turbine is actuated by pressurized water generated in the power recovery system.

    摘要: Silencing equipment provided with one or more flow channels through which cooling air flows has a flow channel forming member that forms the flow channel, and an acoustic absorbent member that is fixed to the flow channel forming member. A resonance type silencer is formed on a wall surface of the flow channel by providing a cavity for the resonance type silencer in the acoustic absorbent member and an aperture for the resonance type silencer in a portion of the flow channel forming member. The resonance type silencer sets a frequency of noise necessary to be reduced based on a peak frequency of noise generated by a fan. The silencing equipment further has a slide member which slides by a slide mechanism to adjust the area of the top of the aperture. The silencing equipment for electronic devices capable of cooling heat generating sections thereof with air has a small and simple structure and can improve a silencing effect by blowing air.
