Publication number: 20100044607Abstract: To provide a mechanism in which a moving body can be stored in a housing. A gate valve has a slide plate and a moving mechanism for changing the positions in the radial and axial directions of the slide plate. A shaft is a rotating shaft the axial displacement of which is controlled by an axial driving mechanism and the angle of rotation of which is controlled by a radial driving mechanism, and is tumably supported in the housing by a shaft supporting spring consisting of a magnetic bearing and a conical coil spring. By controlling the attraction force of a balance weight in an electromagnet, the shaft can be moved in the radial direction.

Publication number: 20090081056Abstract: To form a shock absorbing structure more easily. A shock absorbing structure for consuming shock energy is provided on the flange of a molecular pump. An insertion hole is provided in the flange, and a shock absorbing member formed by an independent and small part is fitted and fixed in this insertion hole. A bolt hole is provided to cause a bolt for fixing the flange and a vacuum vessel in the shock absorbing member to pass therethrough. The shock absorbing member is provided with a thin-wall portion by forming a cavity portion. In the case where a shock in the rotation direction of a rotor portion is produced in the molecular pump, for example, by fracture of the rotor portion, the flange slides in the rotation direction of the rotor portion together with the molecular pump. Thus, the bolt that fixes the flange to the flange of the vacuum pump hits the shock absorbing member, thereby the shock absorbing member is subjected to plastic deformation.Type: ApplicationFiled: March 15, 2007Publication date: March 26, 2009Inventors: Yasushi Maejima, Yoshinobu Ohtachi, Rumiko Wada, Yoshihiro Enomoto, Chris Bailey, Dawn Stephenson, Kate Wilson
