Patent number: 7908737Abstract: A gas is fed, so as to cause a gas flow to occur from a lower opening of a bearing hole of a sleeve 6 in an outward direction of an annular portion 12a of a rotor hub 12 via a radial gap 50 and an upper opening of the bearing hole, thereby lifting a rotor section 10. In a condition where the rotor section 10 is lifted, the magnitude of run-out synchronized with the rotation of the rotor section 10 is measured by using a displacement gauge 40. Then, based on the magnitude of run-out synchronized with the rotation, the run-out of the rotor section 10 is adjusted.Type: GrantFiled: April 23, 2008Date of Patent: March 22, 2011Assignee: Nidec CorporationInventors: Hosei Kudou, Hirofumi Takayama, Takashi Nishina, Masaaki Inagi

Patent number: 5582795Abstract: A hold-transfer system for extraction containers has a main body and a cassette detachable from the main body. The cassette has holding devices for holding extraction containers in an upright position, an endless traveling member carrying the holding devices arranged in a row, and a driving rotor and a driven rotor engaging the endless traveling member about perimeters thereof. The endless traveling member has rotatable support member for rotatably supporting the holding devices with lower portions of the holding devices protruding below the rotatable support members and accessible from beneath the cassette. The main body has a driving motor for driving the driving rotor and an identifying device, installed at a reading position relative to a specified position for an extraction, for identifying an identification mark associated with one of the extraction containers.Type: GrantFiled: April 5, 1995Date of Patent: December 10, 1996Assignees: Furuno Electric Company, Limited, Mitsui Pharmaceuticals, Inc.Inventors: Takashi Nishina, Ryoichi Ito
