Publication number: 20090192641Abstract: A semiconductor manufacturing method and apparatus is provided that can improve uniformity of processing time of oxidation thickness. When starting a heat oxidation process, a time for optimum oxidation processing in the process management system is calculated based on atmospheric pressure data, a target thickness of that process, oxidization time, thickness data and atmospheric pressure data in the immediately preceding process under the same oxidization processing job. The optimum system comprises a process management system such as a host computer, a device having a barometer, a heat oxidation-processing device and a thickness-measuring device. The host computer, the barometer, the heat oxidation processing device and the thickness-measuring device are connected via a network so as to transmit data to and from each device.Type: ApplicationFiled: September 27, 2007Publication date: July 30, 2009Applicant: SEIKO EPSON CORPORATIONInventors: Akira TADANO, Yusuke INOUE, Isao YOKOYAMA

Patent number: 7353748Abstract: A bent section, which is bent substantially perpendicularly toward a main cylinder body, is formed at one end of a slide table. Further, a pair of ball-rolling grooves, in which a plurality of ball bearings roll, are formed on side surfaces of the slide table opposed to a guide section. A relief groove, which has a width wider than a spacing distance between the ball-rolling grooves and which makes it possible to change the direction of a processing jig when the ball-rolling grooves are processed, is formed at ends of the ball-rolling grooves disposed on a side of the bent section.Type: GrantFiled: May 18, 2006Date of Patent: April 8, 2008Assignee: SMC Kabushiki KaishaInventors: Toshio Sato, Akira Tadano, Gen Tsuchiya

Patent number: 7144005Abstract: A clamping device in which there is no need to carry out troublesome setting operation of a clamping position according to a size of a workpiece and wear of respective components and an operation efficiency can be further improved. A worm which is engaged with a worm wheel provided to a periphery of a rotating shaft of a clamping arm and which is connected to an electric motor can reciprocate in an axial direction. On the axis, a clamping force applying mechanism to be actuated in response to contact of the rotated clamping arm with the workpiece to apply an axial force in a direction of the axis to the worm is provided. The clamping arm is rotated by driving the worm for rotation by the electric motor and the clamping force applying mechanism applies a clamping force to the clamping arm which has come in contact with the workpiece.Type: GrantFiled: January 6, 2004Date of Patent: December 5, 2006Assignee: SMC CorporationInventors: Toshio Sato, Akira Tadano

Patent number: 6969056Abstract: A first clamping arm mounted to an arm rotary shaft is rotated by a driving mechanism formed of a worm wheel mounted to the arm rotary shaft, a worm supported on a junction frame, and a first driving source to clamp a workpiece between a second clamping arm and the first clamping arm. A rotating force in a direction opposite to a reaction force in clamping is applied by a clamping force applying mechanism to the junction frame which has been displaced through a certain angle by the reaction force to thereby generate a rotating force in a clamping direction in the arm rotary shaft through the worm and the worm wheel to thereby apply a clamping force to the first clamping arm.Type: GrantFiled: November 13, 2003Date of Patent: November 29, 2005Assignee: SMC CorporationInventors: Toshio Sato, Akira Tadano
