Abstract: A vertical circulating conveyor includes a lowering path part (3) and a raising path part (4) that connect end portions of a conveyance path part (1) and a return path part (2) vertically positioned in a linear arrangement. The lowering path part (3) includes front wheel lowering guide rails (8A) to guide front wheels (F) of a transport vehicle (5) and rear wheel lowering guide rails (8B) to guide rear wheels (R) of the transport vehicle (5). The transport vehicle (5) is moved in the lowering path part (3) by falling under its own weight in almost the horizontal state in a powerless manner while the front wheels (F) of the transport vehicle (5) are guided by the front wheel lowering guide rails (8A) and the rear wheels (R) of the transport vehicle (5) are guided by the rear wheel lowering guide rails (8B).

Abstract: The present invention provides a controlling method for a starting clutch disposed between a transmission and an engine of a vehicle and having a wet type multi-plate clutch for transmitting a power and a piston for pressing the wet type multi-plate clutch to engage the wet type multi-plate clutch, wherein, while the starting clutch is being subjected to creep control, the pressing force of the piston is controlled variably.

Abstract: An ejector is configured to generate a high negative pressure capable of sucking and conveying fine metal pieces or chips, such as machinings or cuttings, for example, when using the ejector as a driving source for a fluid conveyor. The ejector includes a convergent-divergent nozzle having a throat formed between a suction port and a discharge port. Jet blowing holes are formed in the convergent-divergent nozzle to direct a jet stream from upstream of the throat to downstream of the throat, thereby forming a negative pressure. Pressure control holes open to the downstream of the jet blowing holes and are configured to communicate with a pressure space at a pressure level higher than a negative pressure formed by the jet stream and lower than a static pressure of the jet stream and the inside of the convergent-divergent nozzle.

Abstract: An ejector capable of generating a high negative pressure capable of sucking and conveying fine metal pieces such as cuttings, for example, in a case of using the ejector as a driving source for a fluid conveyor, comprising a convergent-divergent nozzle having a throat formed between a suction port and a discharge port in which jet blowing holes are formed in the convergent-divergent nozzle for jetting a jet stream from the upstream to the downstream of the throat thereby forming a negative pressure, wherein pressure control holes are formed being opened to the downstream of the jet blowing holes for communicating a pressure space at a level higher than a negative pressure formed by the jet stream and lower than a static pressure of the jet stream and the inside of the convergent-divergent nozzle.

Abstract: A cam motor apparatus A is configured such that a cylinder block (2) rotating together with an output shaft (10) is internally provided with a plurality of cylinders (5, 5, . . . ) formed radially in a direction orthogonal to a rotational axis (X) of the cylinder block (2) and pistons (6) respectively housed in the cylinders are reciprocated by the action of working oil distributed thereto by a distribution valve (7) thereby rotating the output shaft. The cam motor apparatus A further includes a selector valve (9) for selectively communicating each of the cylinders with a supply passage (81) or a discharge passage (82) for working oil through the distribution valve. When the selector valve is in a low rotational speed position, working oil is supplied to and discharged from all the cylinders.

Abstract: A hydraulic circuit for a so called feathering control of a variable displacement pump in which displacement of the variable displacement pump is controlled to a minimum when every actuator in a system is not in operation thereby keeping a power loss to a minimum. The hydraulic circuit includes a jet flow sensor for detecting a dynamic pressure of fluid. The jet flow sensor is disposed in a circuit for connecting a system pressure line to a reservoir and is adapted to convert static pressure of the fluid to dynamic pressure thereof. This detected dynamic pressure is introduced into a servo mechanism for the variable displacement pump for effecting feathering control.
