Title: Seal device for high vacuum valve
Inventor: SHIMOMURA TOMOYOSHI
IPC: F16K51/02
Filed: 1990-08-28
Abstract: PURPOSE:To reduce a cost and to increase a seal effect by adhering a metallic film on the seal surface of the one of a valve seal and a valve desk, covering the metallic film with a synthetic resin film, and providing a mechanism to press the metallic film against an opposing surface through the synthetic resin film. CONSTITUTION:A metallic film 11 is adhered to the edge part of the seal surface of a valve desk 2, the metallic film 11 is further covered with a heat resisting synthetic resin film 13, and the synthetic resin film 13 is brought into opposite contact with the seal surface of a valve seat 1. The portion, except an end part, of the metallic film 11 is pressurized against the seal surface of the valve seat 1 through the synthetic resin film 13 by means of a pressure mechanism. This constitution reduces a cost since there is no need to provide a mirror finish for the seal surface of the metallic film 11. Further, since the synthetic resin film 13 is soft, it is well doped with lodging of refuse and thus, a seal effect is high.

IPC: G11B7/005
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device wherein a high speed rotation of the disk is achieved and a data transfer rate is improved by adding a disk chucking force increasing mechanism of an eccentric centroid correction clamper to an eccentric centroid correction mechanism while reducing vibrations caused by the disk rotation without losing reliability.

Thus, even a disk with a large amount of eccentric centroid can be rotated at a high speed without generating vibrations, and can be improved in data transfer rate.  Since vibrations and noises are suppressed and there is little change in the correction quantity with an elapse of time even when a disk with a large amount of eccentric centroid is rotated at a high speed, it is possible to realize the eccentric centroid correction mechanism with a high reliability and the optical disk device with it.
