    摘要: A terminal structure has a first connector arranged at a first member, such as a vacuum pump, and a plurality of connector pins. A second member, such as a control device, is movable toward and away from the first member, and a second member side bolt is arranged at the second member. A second connector has a plurality of connecting pins and a flange portion through which the bolt passes and which is movable with respect to the bolt while the second connector is being fit-engaged with the first connector to electrically connect the connector pins of the first and second connectors. An elastic member elastically retains the flange portion and produces an elastic force that resists a push-back displacement which acts on the second connector at the moment of fit-engagement with the first connector in either a direction parallel to the bolt or in a direction inclined at an angle from the parallel direction. The push-back displacement of the flange portion of the second connector is resisted by the elastic force generated by deformation of the elastic member so that excessive force is not applied to the two connectors even if they are obliquely fit-engaged with one another.

    摘要: A vacuum pump is removably connected to the underside of a chamber for exhausting gas molecules from the chamber. The vacuum pump has a pump case having a flange extending circumferentially around a top portion thereof, a suction port and an exhaust port. Stator blades are fixedly mounted within the pump case, and a rotor is rotatably mounted in the pump case and has rotor blades alternately disposed with respect to the stator blades. A driving motor rotationally drives the rotor so that the rotating rotor blades coact with the stator blades to evacuate gas molecules from the chamber and pump the gas molecules from the suction port to the exhaust port. Bolt insertion holes are formed in the flange and each hole has a smaller diameter portion opening at a lower surface of the flange and a larger diameter portion opening at an upper surface of the flange which faces the underside of the chamber. Bolts extend through respective ones of the bolt insertion holes for removably connecting the flange of the pump case to the underside of the chamber, and buffer members are disposed in respective ones of the bolt insertion holes and surround at least a portion of the corresponding bolt in the region between the upper and lower surfaces of the flange.

    摘要: The present invention provides a vacuum pump which reduces a damaging torque produced when a rotor rotating at high-speed crashes into a screw stator or the like. The vacuum pump has a rigid ring disposed around the screw stator such that a shock load from the screw stator causes the rigid ring to rotate. When a brittle facture occurs in the rotor rotating at high-speed, for example, and a part of the rotor crashes into the screw stator, a rotating torque, i.e., a damaging torque causing the entire vacuum pump to rotate is likely to occur. However, this damaging torque is absorbed by the rotation of the rigid ring and eventually subsides.

    摘要: The present invention provides a vacuum pump in which a damaging torque produced when a rotating rotor crashes into the inner wall of a pump case, is prevented to transfer to a vacuum chamber so as to protect the vacuum chamber. Bolt-holes of flange portions, through which the vacuum pump and the vacuum chamber and also the pump case and a base member disposed below the pump case are fastened, respectively, are formed so as to have larger diameters than the shank diameters of corresponding bolts by 20% or more. With this arrangement, when the entire vacuum turns moved by the damaging torque, the pump case slips relative to the vacuum chamber and the base member by the gaps between the pump case-base member fastening bolt-holes and the pump case-base member fastening bolts. As a result, the damaging torque is absorbed and is prevented to transfer to the vacuum chamber.

    摘要: A vacuum pump evacuates gas from a chamber by coaction of a rotationally driven rotor and a stator. An electrical equipment section that rotates the rotor is housed within a stator column integral with the stator. A cooling water pipe is buried in a wall of the stator column near the electrical equipment section. One end of the cooling water pipe branches into a plurality of water inlet ports and the other end branches into a plurality of water outlet ports. One pair of water inlet and outlet ports opens to the outside of the vacuum pump at a side surface of the stator column and another pair of water inlet and outlet ports opens to the outside at the underside of the stator column.
