    摘要： The transverse tooth profile of a screw rotor which meshes with a companion screw rotor is defined by a tooth root circular arc, an outer circumferential circular arc, and two curves interconnecting the tooth root circular arc and the outer circumferential circular arc. One of the curves is defined by a trochoid curve generated by a point on an outer circumferential surface of the companion screw rotor. Alternatively, the curve may comprise two curve segments, and one of the two curve segments comprising a tooth tip arc which is defined as an arc having a radius of curvature equal to or smaller than the difference between a radius of curvature of the outer circumferential circular arc and a radius of a pitch circle of the tooth profile, and the other of the two curve segments comprising a curve connected to the tooth root circular arc and determined by a curve generated by the tooth tip arc of the companion screw rotor. The other curve is defined by determining a curve which defines an imaginary rack and thereafter producing a tooth profile curve generated by the imaginary rack.

    摘要： A bearing lubricating apparatus for a rotary machine has a rotary shaft rotatably supported by a rolling bearing, and an oil receiving portion which receives lubricating oil picked up by a pick-up member. The oil in the oil receiving portion is sucked by a suction nozzle and is sent to interior of the rotary shaft through a first passage. Then, the oil flows back through a second passage into the bearing. Oil supply nozzles are formed in the rotary shaft so that the oil is supplied to the bearing by a pumping action of the oil supply nozzles when the rotary shaft rotates.

    摘要： A trapping apparatus traps solid substances converted from reaction products contained in exhaust gases discharged from a process apparatus by a vacuum pump. The trapping apparatus has a trap member for contacting the exhaust gases and trapping reaction products contained in exhaust gases, and a trap housing (1) accommodating the trap member (4) therein. The trap housing has an inlet port (2) for introducing exhaust gases, and an exhaust gas space (3) connected to the inlet port and having an increased cross-sectional area in the direction in which exhaust gases flow in. The trap housing has a flow passage defined therein for passing the exhaust gases in the exhaust gas space and then changing the direction of the exhaust gases so as to flow from the exhaust gas space substantially perpendicularly to the trap member so as to pass the exhaust gases through the trap member while in contact therewith.

    摘要： A continuous processing trap apparatus is capable of increasing the trapping efficiency while maintaining conductance required by a vacuum chamber. The trap apparatus includes an exhaust passage for evacuating a hermetically sealed chamber by a vacuum pump, a hermetically sealed trapping and regenerating casing extending across the exhaust passage and a regenerating passage adjacent to the exhaust passage, and a trap unit movably housed in the trapping and regenerating casing for selective movement between a trapping position connected to the exhaust passage and a regenerating position connected to the regenerating passage. The trap apparatus further includes valve bodies disposed one on each side of the trap unit and supporting seals on outer circumferential surfaces thereof for sealing the exhaust passage and the regenerating passage from each other, and a monitoring mechanism for monitoring whether the seals are functioning normally.

    摘要： A screw type dry vacuum pump having dual shafts is disclosed, whereby the process gas is transported through three compartments, a gas admittance pump section, a central drive motor section, and a gas discharge pump section. By placing the drive motor in the center of the pump, it becomes possible to design a pump having the dual shafts supported only at one end, thus enabling to mount the rotors at the free ends of the pump which are closed with end plates which can be removed easily for servicing the pump sections. Synchronous operation of the dual shaft pump by magnetic coupling enables to lower power consumption and to extend the range of operable pressures.
