Patent number: 7533185Abstract: In a data communication method, when packet data are sent and received among a plurality of computers connected each other via the network, communications are established by using a unicast connection. Then, the packet data are sent by selectively using a multicast communication and the unicast communication for at least one computer to which the communication is established. As a result, it is possible to reduce an amount of network traffic under a peer-to-peer network without intermediation of a server and improve reliability of the multicast communication.Type: GrantFiled: February 26, 2003Date of Patent: May 12, 2009Assignee: Ricoh Company, Ltd.Inventors: Masami Koide, Akira Suzuki

Patent number: 7507457Abstract: An optical recording medium includes a support substrate, and a light transmission layer 12 that is disposed so as to come in contact with the support substrate. At least one of a refractive index of the support substrate and a refractive index of the light transmission layer, and an extinction coefficient of the support substrate and an extinction coefficient of the light transmission layer is different. As such, according to the invention, a reflective layer is not formed between the support substrate and the light transmission layer, such that the support substrate and the light transmission layer directly come in contact with each other. Accordingly, since at least one of the refractive index and the extinction coefficient is different, reflection occurs at the interface between the support substrate and the light transmission layer. Therefore, data held by a plurality of pits, that are arranged on the support substrate in a spiral shape or a concentric shape, can be correctly read out.Type: GrantFiled: June 1, 2005Date of Patent: March 24, 2009Assignee: TDK CorporationInventors: Koji Mishima, Daisuke Yoshitoku, Kenji Yamaga

Patent number: 7470098Abstract: An optical sensor for detecting the housing state such as the thickness of a substrate in the present invention is provided at supporting arms. The supporting arms are attached to a supporting shaft. The supporting arms are in a vertical state in a state before detection of the substrate, but when detecting, the supporting shaft rotates to bring the supporting arms into a horizontal state so that the optical sensor enters a substrate housing body and is set at a predetermined detection position. Accordingly, a space for moving the optical sensor in the horizontal direction becomes unnecessary to reduce the space required for the detecting operation and the like, making it possible to reduce the size of a substrate processing apparatus in which the detecting apparatus is incorporated.Type: GrantFiled: October 12, 2007Date of Patent: December 30, 2008Assignee: Tokyo Electron LimitedInventor: Naruaki Iida

Patent number: 7304968Abstract: In an ad-hoc established device network, a profile based handover of the network control functionality is performed whenever a new device (15) requests association with the network and the central controller (16) does not support the profile of the new device (15). A database is searched for a controller-capable device that supports both the profiles of the network devices and the profile of the new device. The former central controller (16) passes the control functionality to the controller-capable device (17), which becomes the new central controller (24). Thus it is possible to associate the new device (15) with the network. The invention allows to integrate devices supporting different profiles into a common network.Type: GrantFiled: August 30, 2002Date of Patent: December 4, 2007Assignee: Sony Deutschland GmbHInventors: Frank Dawidowsky, Lothar Stadelmeier
