Patent number: 6260404Abstract: A method for manufacturing a cylinder interior fuel injection valve and an apparatus for adjusting a fuel injection amount used therefor may sufficiently cope with a fluctuation in fuel pressure or combustion gas pressure that would occur in an actual engine. According to this manufacturing method, a position of an adjuster is adjusted (step 110), a fuel injection amount is measured (step 111), and it is judged whether or not the measured value of the fuel injection amount falls within a range of a rated value (step 112). Then, if the fuel injection amount is out of the range of the rated value, the process is returned back to the step 110, and if it falls within the range of the rated value, the process shifts to a subsequent step 113. Subsequently, a spring force of a valve closing spring is measured (step 113), and it is judged whether or not the measured value of the spring force falls within a control range (step 114).Type: GrantFiled: June 12, 1998Date of Patent: July 17, 2001Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Masayuki Aota, Mamoru Sumida, Kazuo Matsunaga, Tsuyoshi Munezane

Patent number: 6189032Abstract: A client-server system is provided in which access to a service by a user can properly be controlled, even if an approval by another user is required for receiving the service. First, the server 2 executes a log-in processing by using a user identifier and password transmitted from the client terminal 2, and a user control file 202. Next, the server 2 executes a service control by using a service supply request transmitted from the client terminal 1 and a service control file 42 provided with the server. When the server determines that an approval by another user is required for providing the service, the server executes the approval request to the client terminal 1 that the concerned user uses. When the reply to the approval request is affirmative, the server executes the processing in accordance with the foregoing service supply request. When the reply is negative, the server informs to the user who made the foregoing service supply request that the approval is rejected.Type: GrantFiled: January 29, 1998Date of Patent: February 13, 2001Assignee: Hitachi, Ltd.Inventors: Seiichi Susaki, Hisashi Umeki, Katsuyuki Umezawa, Seiji Miyazaki, Kazuo Matsunaga, Makoto Kitagawa
