Patent number: 7089227Abstract: In a full text search retrieval device connected to a plurality of user terminals, a received retrieval condition and terminal device information are stored in a trailing character buffer. If it is determined that a preceding retrieving process is not being performed, then a retrieval pattern variable table and a retrieval request expression variable table are generated. According to the retrieval request expression variable table, a database of the data to be searched is searched to extract a retrieval result matching the retrieval condition transmitted from each of the terminal devices, and the extracted retrieval result is transmitted to each of the plurality of terminal devices. Thus, although retrieval requests are continuously transmitted from respective users, a retrieval result can be returned to each user terminal in the same response time as in the case where a user terminal corresponds to a retrieval device.Type: GrantFiled: December 3, 2001Date of Patent: August 8, 2006Assignee: Fujitsu LimitedInventors: Fumirou Abe, Masataka Matsuura, Masahiko Nagata, Yasuhisa Hara

Publication number: 20060171662Abstract: In a conventional control apparatus, the control apparatus cannot be correctly set into a fail safe mode upon failure of a temperature sensor itself mounted in the control apparatus. Also, when the control apparatus has a plurality of elements having a concern of heat generation, a plurality of temperature sensors are required corresponding to the elements having a concern of heat generation. The requirement of the plurality of temperature sensors causes an increase in the cost and mounting area. The present invention measures an instructed current value from a CPU to an element mounted in a control apparatus and having a concern of heat generation (typically, a current control element), calculates power consumption from the measured current value and a monitored source voltage, and predicts a temperature rise of the control apparatus by multiplying the power consumption by a thermal resistance parameter of the control apparatus.Type: ApplicationFiled: August 17, 2005Publication date: August 3, 2006Applicant: Hitachi, Ltd.Inventors: Yasuhiko Nagata, Itaru Tanabe
