Patent number: 8521459Abstract: In an instantaneous voltage drop compensating device, when an instantaneous drop occurs, an electric power transformer (8) performs an inverter action so that the electric power of a side-by-side placed capacitor (7) is DC/AC-converted and fed to a load (3). At this time, a capacitor's remaining lifetime diagnosing unit (100) introduces the DC voltage value, the DC current value, and the temperature value of the side-by-side placed capacitor (7) thereinto, and uses a prestored program for computing a remaining lifetime, thereby diagnosing the remaining lifetime, for which the side-by-side placed capacitor (7) can be used under the state where a capacitor discharge time period exceeds a rated compensation time period.Type: GrantFiled: June 5, 2009Date of Patent: August 27, 2013Assignee: Meidensha CorporationInventors: Hiroyuki Watanabe, Hiromichi Itoh, Yoshitaka Sakai

Patent number: 7908517Abstract: An information processing apparatus having a resume function which can maintain the security even when a plurality of users commonly use the apparatus. A work state at a power-off time of the apparatus is preserved together with a work state name including a user's ID in a different area in a plurality of preservation areas for resume function on a main memory for each user. When a power source is again turned on, data in the preservation area corresponding to the user's ID is used to reproduce the work state of the user at the power-off time. The work preservation areas can be provided on a file server apparatus in a network not needing battery back-up. When the information processing apparatus is used, a work state at a power-off time can be independently preserved and reproduced for each user.Type: GrantFiled: December 2, 2009Date of Patent: March 15, 2011Assignee: Hitachi, Ltd.Inventors: Hiromichi Itoh, Keiichi Nakane, Naomichi Nonaka, Yoshinori Watanabe

Patent number: 5619716Abstract: An information processing system in which update processes are automated in conformity with types of client machines, to thereby dispense with manual version update processes, and within which redirectors of identical version are run at any time, to thereby prevent any error ascribable to different programs from occurring. When a redirector stored in the client machine is started, it notifies version information of its own to a configuration management program stored in a server machine. In a case where version information of a redirector stored in a configuration management database is newer than the notified version information, the configuration management program sends an update request back to the redirector of the client machine and transfers the new redirector to the client machine so as to update the redirector thereof.Type: GrantFiled: June 6, 1995Date of Patent: April 8, 1997Assignee: Hitachi, Ltd.Inventors: Naomichi Nonaka, Keiichi Nakane, Hiromichi Itoh, Hideaki Ishida

Patent number: 5552901Abstract: A facsimile server system which can be utilized similarly to a stand-alone FAX. A remote FAX includes a scanner, a printer and a FAX communication unit. A client delivers document data to a FAX server, and makes a request for FAX transmission/printing. The FAX server expands the document data requested to be transmitted, into image data, and it transfers the image data to the appropriate remote FAX and gives a command for the FAX transmission/printing. When instructed to perform FAX transmission directly by a user, the remote FAX accepts the image of a handwritten document, and it subsequently delivers the image data of the document to the FAX server and makes a request for the FAX transmission. Besides, when the remote FAX has been commanded to scan image data or has received image data as FAX reception, it delivers the scanned image data or the received image data to the FAX server. Then, the FAX server accumulates the image data and offers them to the client in accordance with a retrieval process.Type: GrantFiled: January 28, 1994Date of Patent: September 3, 1996Inventors: Satoshi Kikuchi, Keiichi Nakane, Hiromichi Itoh, Hiroshi Kawamura
