摘要： A vacuum pump having a rotary shaft that is rotated by a drive source has a main pump and a sub pump. The main pump includes a pump chamber and a gas transferring body that is located in the pump chamber. The main pump is driven by the drive source through the rotary shaft for transferring gas to an exhaust space. The sub pump is connected to the exhaust space for partially exhausting the gas from the exhaust space. The sub pump is driven by the same drive source. The displacement volume of the sub pump is smaller than that of the main pump.

摘要： A cooling unit which contains refrigerant for exchanging heat with an object member of cooling includes a refrigerant passage and cooling means. The refrigerant passage allows the refrigerant to circulate therethrough. The cooling means communicates with the refrigerant passage for supplying the refrigerant passage with the refrigerant. The cooling means includes a refrigeration circuit, a compressor, a condenser, decompression means, an evaporator, a refrigerant supply path, a refrigerant return path, refrigerant control means and first pressure control means. The refrigerant control means has an on mode which allows the refrigerant to circulate through the refrigerant passage at a flow rate which enables the refrigerant to maintain gas-liquid two-phase flow by allowing the condenser to communicate with the refrigerant passage, and an off mode which prevents the refrigerant from circulating through the refrigerant passage by preventing the condenser from communicating with the refrigerant passage.

摘要： A screw pump is provided with a pair of screw rotors serving as fluid transfer bodies. With respect to a rotation angle (x) around an axis of each of the screw rotors, a change of a lead angle (θ) from a winding start angle (0), which is the rotation angle (x) corresponding to a leading end of a spiral groove, to a winding end angle (E), which is the rotation angle (x) corresponding to a trailing end of the spiral groove, can be expressed by a lead angle change function θ(x). The lead angle change function θ(x) is structured by a combination of a plurality of change functions θ1(x) and θ2(x) having different manners of changing. It is possible to arbitrarily set a manner in which the lead angle (θ) changes in accordance with a combination of a plurality of change functions θ1(x) and θ2(x). Therefore, it is possible to arbitrarily set a fluid compression characteristic of the pump in a relation with an axial length (L) of the screw rotor.
摘要翻译：螺杆泵设有一对用作流体传递体的螺杆转子。对于围绕每个螺杆转子的轴线的旋转角度（x），与作为与前端的旋转角度（x）对应的卷绕起始角度（0）的导角（θ）的变化，螺旋槽的螺旋槽的旋转角度（X）与螺旋槽的后端相对应的旋转角度（X）可以由引导角变化函数θ（x）来表示。引导角变化函数theta（x）由具有不同变化方式的多个变化函数theta1（x）和theta2（x）的组合构成。可以根据多个变化函数θ1（x）和theta2（x）的组合来任意设定引导角（θ）变化的方式。因此，可以将泵的流体压缩特性与螺杆转子的轴向长度（L）成一定关系。

摘要： A diaphragm unit includes a diaphragm and a diaphragm case. The diaphragm has a center point and an outer peripheral portion. The diaphragm case includes a fixing surface and a regulating surface. The fixing surface supports the diaphragm at the outer peripheral portion thereof, thereby defining a fluid chamber in the diaphragm case. The regulating surface forms an inner surface of the fluid chamber, thereby providing a limit of deformation of the diaphragm. The regulating surface has a convex surface region and a concave surface region. The convex surface region is formed continuously with the fixing surface for supporting the diaphragm at a portion thereof adjacent to the outer peripheral portion. The concave surface region is formed continuously with the convex surface region for supporting the diaphragm at a portion thereof adjacent to the center point. Curvatures of the convex and concave surface regions are the same.

摘要： A Roots pump rotates a plurality of rotors by a pair of rotary shafts to draw gas. Each rotary shaft extends through a rear housing member of the Roots pump. A plurality of stoppers are located on each rotary shaft to integrally rotate with the corresponding rotary shaft, and prevent oil from entering a fifth pump chamber of the Roots pump. Stoppers have a circumferential surface, respectively. Annular oil chambers collect oil. The oil chambers are located about an axis of the rotary shaft to surround the circumferential surface of the stopper. This effectively prevents oil from entering the pump chamber of the Roots pump.
