    摘要: A variable displacement piston pump of the type in which the hydraulic pressure in a pressure chamber of an output flow variable element is controlled by a proportional electro-hydraulic control valve to control the displacement of the variable element against a spring to vary the output flow within a range between a maximum output flow and a full cut-off and the output pressure or both the output pressure and the output flow of the pump are controlled electro-hydraulically through a closed loop. The variable displacement piston pump includes flow detector for generating an electric signal corresponding to the output flow of the pump, pressure detector for generating an electric signal corresponding to the output flow of the pump, and control amplifier responsive to the difference between a flow setting signal and the output signal of the flow detector to control a driving control current supplied to the proportional electro-hydraulic control valve and also responsive to the detected output pressure reaching a predetermined value to control the driving control signal in accordance with the difference between a pressure setting signal and the output signal of the pressure detector.

    摘要: Each of fins is provided with an engage projection having a first width and a engage hole portion having a second width wider than the first width, and the fins are able to be slid while engaging with each other. Accordingly, in case of installing a heat sink to a case of a fan, it is possible to install the fins to the case so that the fins are arranged in a flowing direction of a refrigerant by the fan while engaging with each other. As the result, the refrigerant is able to flow smoothly when passing through the fins by arranging the fins at desired angle. Accordingly, it becomes possible to present a radiation fin, a cooling device and an electronic equipment having such cooling device.

    摘要: A bearing unit is provided which supports a shaft (51) rotatably. It includes the shaft (51), a radial bearing (55) to support the shaft (51) circumferentially, a thrust bearing (58) to support the shaft (51) at one of thrusting-directional ends of the latter, a housing (56) having disposed therein the radial bearing (55) and thrust bearing (58) supporting together the shaft (51) and which is filled with a viscous fluid (67), and a spacer member (65) disposed inside the housing (56) to keep a gap defined between the end face of the radial bearing (55) and one side of a radial projection (54) included in the shaft (51). On the end face of the radial breading (55) opposite to one side of the radial projection (54), there is formed a first dynamic pressure producing recess (63) which produces a dynamic pressure by the viscous fluid. Also, on the side of the thrust bearing (58) opposite to the other side of the radial projection (54), there is formed a second dynamic pressure producing recess (64) which produces a dynamic pressure by the viscous fluid. As the shaft (51) rotates, the viscous fluid is circulated through the first and second dynamic pressure producing recesses (63, 64) to produce a dynamic pressure between the shaft and the radial and thrust bearings, respectively. The space member (65) provided as above permits to control the gap between the radial projection (54) and first and second dynamic pressure producing recesses (63, 64), respectively, with a high accuracy.

    摘要: The rotation of axial-flow blades permits air entered through an inlet port to exit directly to outside of a case in the axial direction, and the rotation of centrifugal blades permits air entered through the inlet port to exit through a side surface outlet port to the outside of the case in the centrifugal direction. Accordingly, the amount of flow of air exiting from inside of the case can be increased so that the amount of heat dissipation is increased. It is therefore able to provide a cooling apparatus and electronic equipment mounting the cooling apparatus with improved cooling efficiency while achieving a small thickness.

    摘要: A fan motor having a small thickness and its impeller's blades formed to have a longer length in the diametrical direction than a width in the axial direction. Since the blade of the fan motor has a tooth structure or chamfers at its edge end in the diametrical direction, turbulence is forcibly evoked in an airflow to promote the turbulent diffusion, thereby suppressing the trailing vortex and reducing the aerodynamic noises, and thus the ventilation efficiency is improved.
