A car seat fabric is simulated with a feeling of reality. A fabric texture information input acceptance portion (101) accepts texture information about the fabric used for the car seat fabric. A thread information input acceptance portion (102) accepts thread information about threads used for the fabric. A 3-D fabric image creation portion (103) creates a steric structure of the car seat fabric as a 3-D fabric image on the basis of the texture information accepted at the fabric texture information input acceptance portion (101) and the thread information accepted at the thread information input acceptance portion (102). An image attachment portion (105) attaches the 3-D fabric image created by the 3-D fabric image creation portion (103) to a car seat model. A car seat image display (402) displays the car seat model to which the 3-D fabric image is attached by the image attachment portion (105).

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.

Also, a plurality of connecting portions are selected from these connecting portions, and the connection configuration shown in the first or second embodiment may be used in the selected connecting portions. For example, the connection configuration shown in the first or second embodiment may be used in the connecting portion between the vacuum vessel 2 and the casing 3 and the connecting portion between the casing 3 and the base 10, or may be used in the connecting portion between the vacuum vessel 2 and the casing 3 and the connecting portion between the casing 8 and the casing 9, or may be used in the connecting portion between the casing 8 and the casing 9 and the connecting portion between the casing 3 and the base 10. That is, the connection configuration shown in the first or second embodiment can be used by changing the combination of connecting portions to which the connecting configuration is applied.

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.

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.

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.

An orthogonal coordinate type robot comprises a slider and a support frame supporting the slider for movement within a predetermined range along an axis. The support frame has an inner wall surface, at least one hollow portion, and a connecting hole for communicating the hollow portion with the inner wall surface. A suction device evacuates air from the hollow portion of the support frame.

The present invention provides a splinter shield for a vacuum pump, capable of reducing costs of the splinter shield by obtaining a single sheet of splinter shield having a required strength, in which fastening strength to a fixing groove is enhanced to prevent the splinter shield from bending toward the inside of a pump and coming into contact with equipment inside the pump when air rushes into the pump through an inlet port and to prevent the splinter shield from falling. Furthermore, attachment and removal of the splinter shield with respect to the inlet port are facilitated.The present invention is a splinter shield for a vacuum pump in which a rim formed in a circumferential edge portion of the splinter shield is inserted into a fixing groove that is provided in a concave manner in an inner circumferential portion of an inlet port, and the splinter shield is provided in a tensioned manner to the inlet port by pushing a retaining ring into the fixing groove, wherein locking parts that are locked into the retaining ring at a plurality of sections in the rim are provided in a standing manner at substantially right angles to the rim.

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.
