Patent number: 8423661Abstract: A transmit packet generated by a CPU 1 is held in a buffer 100a (100b). From among packets received from Ethernet 820a (820b), a packet, a destination of which is a communication device 800, is held in the buffer 100a (100b). A packet which should be transmitted is transmitted from a transfer judging circuit 200 to Ethernet 820a or 820b through a MAC unit 300a or 300b. If a transfer judging circuit 200 judges a packet from the Ethernet 820a to be a packet, a destination of which is another communication device, with reference to a destination MAC address, this packet is transferred to the Ethernet 820b through MAC 300b. If a usage rate of a transferring FIFO buffer 130a (130b) exceeds a threshold value in the process of transmitting a packet held in a transmitting FIFO buffer 120a (130b) on a priority basis, the priority order of a transfer packet is made higher than that of a transmit packet so that the transfer packet is transferred to the Ethernet 820a or 820b in preference to the transmit packet.Type: GrantFiled: September 1, 2010Date of Patent: April 16, 2013Assignees: Renesas Electronics Corporation, Hitachi Information & Control Solutions, Ltd.Inventors: Hiroshi Arita, Yasuhiro Nakatsuka, Yasuwo Watanabe, Kei Ouchi, Yoshihiro Tanaka, Toshinobu Kanai, Masanobu Tanaka, Kenji Furuhashi, Tomoaki Aoki

Patent number: 8086428Abstract: An initial layout of one pitch unit of a tire tread pattern is decided. A finite element model of a tire is created by developing the one pitch unit of the initial layout into a plurality of pitches in the circumferential direction of the tire to carry out a structural analysis. Evaluation indices calculated through the analysis are integrated into one pitch unit for each element associated with the indices. The elements are classified according to the magnitudes of the integrated evaluation indices to determine a plurality of classes to which elements subject to removal belong, and elements to be removed are selected from each of classes thus determined. Elements to be added are selected from among the elements which have been removed to decide a layout of the current generation. A finite element model of a tire is created by developing the layout of the current generation into a plurality of pitches to carry out a structural analysis, and convergence of an objective function is determined.Type: GrantFiled: April 7, 2008Date of Patent: December 27, 2011Assignee: Toyo Tire & Rubber Co., Ltd.Inventors: Yoshihiro Tanaka, Ken Ishihara
