Patent number: 7311515Abstract: A first transfer mechanism of a biaxial stretch blow-forming apparatus has sliders that are transported along a circular transportation passage. The sliders slide along a circular guide rail installed on a turntable. Each of the sliders is swung to left and right by a swing arm as the turntable rotates, and a feed pitch of a preform holding groove formed in a holding plate installed at an end of each of the sliders is changed. The feed pitch can be changed by a simple mechanism. Because the holding groove always faces a radial direction, receiving and handing over actions of a preform sent along the circular transportation passage can be reliably performed.Type: GrantFiled: November 7, 2003Date of Patent: December 25, 2007Assignee: Frontier Inc.Inventor: Yoichi Netsu

Patent number: 7313462Abstract: An integrated tool and automatic calibration systems that enable wet chemical processing chambers, lift-rotate units and other hardware to be quickly interchanged without having to recalibrate the transport system or other components to the replacement items. These tools are expected to reduce the down time associated with repairing or maintaining processing chambers and/or lift-rotate units so that the tools can maintain a high throughput. Several aspects of these tools are particularly useful for applications that have stringent performance requirements because components are more likely to require maintenance more frequently, and reducing the down time associated with maintaining such components will significantly enhance the integrated tool.Type: GrantFiled: June 3, 2004Date of Patent: December 25, 2007Assignee: Semitool, Inc.Inventors: Daniel J. Woodruff, David P. Mattson, James J. Erickson, Matthew C. Egloff

Publication number: 20070280813Abstract: A vacuum robot includes an arm portion on which a work is to be disposed under a reduced pressure environment and a motor portion for rotatably driving the arm portion, the vacuum robot being configured to transfer the work by causing a rotational movement of the arm portion by the motor portion. The motor portion comprises a rotor portion connected to the arm portion, a stator portion disposed at an external periphery of the rotor portion, a housing disposed under an atmospheric pressure environment, and a thin cylindrical can disposed in an electromagnetic gap formed between the rotor portion and the stator portion and secured to the housing so that the stator portion is air-tightly encapsulated in a space formed by the housing and the can. The space is maintained in a depressurized state by a seal.Type: ApplicationFiled: June 1, 2007Publication date: December 6, 2007Applicant: KABUSHIKI KAISHA YASKAWA DENKIInventors: Takayuki NAKAMURA, Tadataka NOGUCHI, Yoshihiro KUSAMA

Patent number: 7292354Abstract: An apparatus for the photoelectric measurement of an essentially planar measurement original includes a photoelectric scanner and a positioning arrangement for the two dimensional movement of the scanner over the measurement original positioned on a supporting surface and the positioning at defined measurement locations on the measurement original. The positioning arrangement is constructed as a type of SCARA robot and includes a stationary base, a first and a second movable robot arm and a positioning control. The first robot arm is mounted on the stationary base for rotation by a motor about a first axis of rotation perpendicular to the supporting surface. The second robot arm is mounted at the free end of the first robot arm for rotation by a motor about a second axis of rotation perpendicular to the supporting surface and carries the scanner, and the positioning control is constructed for rotation of the two robot arms according to externally supplied positioning commands.Type: GrantFiled: April 19, 2005Date of Patent: November 6, 2007Assignee: X-Rite Europe AGInventors: Fortunat Schrämmli, Guido Keller
