Patent number: 8823309Abstract: Disclosed is a smaller and lighter stage device which can be applied to a device such as a length measurement SEM for inspecting and/or evaluating a semiconductor, and in which the effect of a magnetic field on an electron beam can be reduced. Linear motors 110, 111, 112, 113 are disposed on four sides of a base 104 to be distanced from an electron beam projection position (the center of the stage device), respectively. The base 104 has dimensions substantially equivalent to minimum dimensions determined by the size of a top table 101 and a movable stroke. Linear motor stators 110, 112 are configured to have a “C-shaped” structure whose opening faces outside of the stage device, respectively. Further, a movable table is coupled to the top table via linear guides 107, 109 composed of a nonmagnetic material or roller mechanisms composed of a nonmagnetic material.Type: GrantFiled: September 17, 2010Date of Patent: September 2, 2014Assignee: Hitachi High-Technologies CorporationInventors: Hironori Ogawa, Masahiro Koyama, Nobuo Shibata, Masaru Matsushima, Shuichi Nakagawa, Katsunori Onuki, Yoshimasa Fukushima

Publication number: 20140042338Abstract: A stage apparatus includes a column for irradiating a sample with a charged particle beam, a vacuum sample chamber to which the column is attached, moving tables disposed in the vacuum sample chamber to move the sample relatively to the column, and position detectors for detecting positions of the moving tables. The stage apparatus includes an attachment member disposed between the column and the vacuum sample chamber. The attachment member has an opening which restricts movement of the column in a same direction as directions of the moving tables. Reference mirrors in the position detectors for detecting the positions of the tables are attached to the attachment member. Each of the reference mirrors has an adjustment apparatus to adjust a relative angle between the reference mirror and the laser beam.Type: ApplicationFiled: March 7, 2013Publication date: February 13, 2014Applicant: Hitachi High-Technologies CorporationInventors: Nobuo Shibata, Masahiro Koyama, Hironori Ogawa, Katsunori Onuki, Hiroyuki Kitsunai, Shuichi Nakagawa, Masaki Mizuochi, Satoru Okabe

Patent number: 8052530Abstract: To provide a network game system for switching a server-client machine without deteriorating the excitement of a game. A network game system (10) causes each of a plurality of game machines (12) to operate as a client and at least one of the plurality of game machines (12) to also operate as a server, thereby providing a game to be played by the players of the plurality of game machines (12). A game play evaluation value calculation unit (40) calculates a play evaluation value corresponding to each of the plurality of game machines (12) during a game. In the case where a predetermined switching determination time arrives during the game, a server switching unit (52) switches the game machine (12) operating as the server from the game machine (12) currently operating as the server to another game machine (12) of the plurality of game machines (12), based on the evaluation value calculated by the play evaluation value calculation unit (40).Type: GrantFiled: September 13, 2006Date of Patent: November 8, 2011Assignee: Konami Digital Entertainment Co., Ltd.Inventors: Katsunori Onuki, Ken Goto, Shin Tsuchiya, Toshikazu Munemasa

Patent number: 7284906Abstract: An exhaust apparatus for a differential exhaust mechanism having a labyrinth seal and a plurality of vacuum pockets includes a differential exhaust system for evacuating the vacuum pockets and an exhaust system for evacuating a chamber of exhaust gas. The differential exhaust system and the exhaust system are connected by control valves that can be opened and closed, enabling communication between the vacuum pockets and the interior of the chamber to be opened and closed (or connected and disconnected) as well. The valves are opened when a vacuum is being formed inside the chamber or when a malfunction occurs in the exhaust system, thus connecting the vacuum pockets and the chamber and preventing excessive pressure from building up on the hydrostatic bearing.Type: GrantFiled: January 28, 2003Date of Patent: October 23, 2007Assignees: Canon Kabushiki Kaisha, Hitachi High-Technologies CorporationInventors: Keiji Emoto, Katsunori Onuki
