Patent number: 8755307Abstract: A path-information obtaining unit obtains a piece of path information of a communication network by inquiring a port number of an Ethernet switch that transmits a MAC address of a request source of an IP address. An IP-address specifying unit specifies an IP address that corresponds to the piece of path information of the communication network by referring to an IP-address correspondence table, and distributes the specified IP address to the request source of an IP address.Type: GrantFiled: January 20, 2010Date of Patent: June 17, 2014Assignee: Mitsubishi Electric CorporationInventors: Tetsuya Shigeeda, Hiroyuki Ohata

Patent number: 8743873Abstract: A train communication system includes a communication relay device that is installed in each vehicle and a communication terminal device that is connected to the communication relay device. The communication relay device acquires vehicle information indicating an in-formation position of a vehicle in which the communication relay device is installed. The communication terminal device refers to a correspondence table that defines a correspondence relationship between vehicle information and communication identification information, and determines communication identification information to be provided to the communication terminal device, based on vehicle information obtained from the communication relay device.Type: GrantFiled: January 20, 2010Date of Patent: June 3, 2014Assignee: Mitsubishi Electric CorporationInventors: Tetsuya Shigeeda, Hiroyuki Ohata

Patent number: 7924693Abstract: An optical disk physical has a recording region divided into zones, each zone including physical tracks adjacent to each other. An integer number of sectors are provided in each physical track. The angular recording density is higher in the more outward zones such that the linear recording density is substantially constant throughout the recording region, and logical tracks are formed of a predetermined number of sectors, independent of the physical tracks. The conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from a host device is easy. The addresses written in headers of the sectors in the logical track in which data are actually recorded, including substitute sectors used in place of defect sectors, are preferably consecutive to further facilitate the conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from the host device.Type: GrantFiled: September 5, 2006Date of Patent: April 12, 2011Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kyosuke Yoshimoto, Mahesh C. Rao, Hiroyuki Ohata, Kazuhiko Nakane, Teruo Furukawa, Junichi Kondo, Masafumi Ototake

Patent number: 7563337Abstract: This invention aims to provide a composite sheet having a layer of inelastically stretchable continuous fibers improved so that a possible unevenness in fiber diameter may be minimized. A composite sheet comprises an elastically stretchable layer and an inelastically stretchable layer formed with inelastically stretchable continuous fibers bonded to at least one surface of the elastically stretchable layer intermittently in one direction. The continuous fibers are oriented substantially in one direction thereof so that the composite sheet may present a ratio S1/S2 of 3.0 or higher where S1 represents a tensile strength in this one direction and S2 represents a tensile strength in the direction orthogonal to this one direction.Type: GrantFiled: September 1, 2005Date of Patent: July 21, 2009Assignee: Uni-Charm CorporationInventors: Satoru Tange, Hiroyuki Ohata
