Publication number: 20100326901Abstract: Provided are a pressure vessel for a membrane element in which the membrane element can be easily mounted, a membrane filtration apparatus equipped with the pressure vessel for a membrane element, and a method for manufacturing a membrane filtration apparatus. A rail (protrusion) 60 is formed on the inner circumferential surface of the pressure vessel 40 in such a manner that a ridge line 61 extends along the insertion direction of the membrane element. Consequently, the membrane element 10 can be inserted into the pressure vessel 40 so as to be in a sliding contact onto the ridge line 61 of the rail 60 formed on the inner circumferential surface of the pressure vessel 40. Therefore, the frictional resistance can be reduced as compared with conventional ways, so that the membrane element 10 can be easily mounted onto the pressure vessel 40.Type: ApplicationFiled: February 20, 2009Publication date: December 30, 2010Inventors: Shinichi Chikura, Toshimitsu Hamada, Masashi Beppu, Yasuhiro Uda, Masakatsu Takata

Patent number: 6002989Abstract: Inspection apparatuses of an inspection apparatus group are connected to a network and transfer inspected result to a data collection system. The same wafer selected from a specific process is inspected by the different inspection apparatuses and the inspected data are collected and analyzed to calculate a correlation degree among the inspection apparatuses. On the other hand, the course of occurrence of failures in the same process can be analyzed to thereby calculate an average occurrence frequency of failures. An optimum inspection apparatus and inspection frequency are successively obtained on the basis of calculated results of an inter-apparatus correlation degree calculation process and a failure occurrence frequency calculation process, so that a feeding method of wafers to the inspection apparatus group is indicated through an inspection apparatus group management system.Type: GrantFiled: April 1, 1997Date of Patent: December 14, 1999Assignees: Hitachi, Ltd., Hitachi Electronics Engineering Co., Ltd.Inventors: Masataka Shiba, Kenji Watanabe, Toshimitsu Hamada, Seiji Ishikawa, Naoki Go, Toshiaki Yachi, Tetsuya Watanabe, Takahiro Jingu

Patent number: 5059559Abstract: The present invention relates to a multi-pin chip mounting method and apparatus based on a TAB (Tape Automated Bonding) system in which leads formed on a tape and bumps formed an IC chip are aligned with each other and compress-bonded to each other. An IC chip having bumps formed on a surface thereof and inner leads formed on a carrier tape are disposed opposite to each other at a bonding station. A position of the IC chip on a stage is detected through the inner leads at the bonding station to determine the amount of correction of position of the stage. The inner leads and the IC chip are aligned with each other on the basis of the determined correction amount and are thereafter bonded to each other.Type: GrantFiled: November 1, 1988Date of Patent: October 22, 1991Assignee: Hitachi, Ltd.Inventors: Michio Takahashi, Tooru Mita, Yasuo Nakagawa, Toshimitsu Hamada, Hisafumi Iwata, Aizo Kaneda, Kouji Serizawa, Hiroyuki Tanaka, Koichi Sugimoto, Toshihiko Sakai, Keizo Matsukawa, Tsutomu Mimata
