Publication number: 20100086392Abstract: A method is provided of manufacturing semiconductor devices formed on a semiconductor wafer, including placing the wafer in a semiconductor container and conveying the container to a semiconductor manufacturing apparatus. An opening of the container is opposed to an opening of the apparatus such that an opener of the apparatus holds a lid of the opening the container. A key of the opener is inserted to a latch groove of the lid, and the key is rotated to contact a latch of the lid. The openings are connected such that a velocity differential pressure ratio obtained by dividing the maximum velocity when the opener holding the lid horizontally moves away from the opening of the container, by the differential pressure between the inside pressure and the outside pressure of the apparatus, is set to be 0.06 ((m/s)/Pa) or less, and then the wafer is processed.Type: ApplicationFiled: September 29, 2009Publication date: April 8, 2010Inventors: Yoshiaki Kobayashi, Shigeru Kobayashi, Kenji Tokunaga, Koji Kato, Teruo Minami

Patent number: 7314345Abstract: When a conventional semiconductor container opening/closing apparatus opens a lid of a semiconductor container, foreign particles enter into the container from outside through a gap between the container and a wall surface of the container opening/closing apparatus and adhere to a wafer in the container. An apparatus is provided to reduce the number of foreign particles adhering to the wafer by preventing foreign particles from entering into the container at the time of opening the container by the opening/closing apparatus. To achieve this, a velocity-differential pressure ratio obtained by dividing the maximum velocity at the time of opening the lid of the container in a vertical direction to an opening of the container, by the differential pressure between the inside pressure and the outside pressure of said semiconductor manufacturing apparatus, is set to be 0.06 ((m/s) Pa) or less.Type: GrantFiled: March 29, 2006Date of Patent: January 1, 2008Assignees: Renesas Technology Corp., Hitachi Plant Engineering & Construction Co., Ltd.Inventors: Yoshiaki Kobayashi, Shigeru Kobayashi, Kenji Tokunaga, Koji Kato, Teruo Minami

Patent number: 4508388Abstract: A hoist control valve interlock system for trolley-assisted dump trucks prevent a dump vessel from an unexpected upward movement caused by the operator's mismanipulation during running on an ascent course under the trolley mode condition. The interlock system has a pair of air cylinders for controlling a hoist control valve operatively connected to hoist cylinders for the dump vessel and directional control air valves for supplying and discharging compressed air from an air reservoir via a trolley mode interlock valve into and from the air cylinders by the operation of a hoist control lever. When the trolley mode interlock valve is shifted to its engine mode position to its trolley mode position, the hoist control valve is interlocked into its floating position by the action of one of the air cylinders where compressed air is supplied from the air reservoir via the trolley mode interlock valve and a shuttle valve irrespective of the air valves.Type: GrantFiled: May 26, 1983Date of Patent: April 2, 1985Assignee: Kabushiki Kaisha Komatsu SeisakushoInventor: Teruo Minami
