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: 7679879Abstract: An air cleaner includes an ion generator arranged in a path from an inlet port to an outlet port, a humidifying filter arranged in the path at a position closer to the inlet port than the ion generator, a dust sensor and an odor sensor for detecting impureness of air, and a temperature sensor and a humidity sensor. When impureness is detected by the dust sensor and the odor sensor and when the temperature and the humidity attain a specific state (YES at S06 to S08), a fan motor is driven such that water is supplied to the ion generator in an amount larger than when the specific state is not attained (S14).Type: GrantFiled: August 4, 2005Date of Patent: March 16, 2010Assignee: Sharp Kabushiki KaishaInventors: Kenji Furuhashi, Takashi Kohama

Patent number: 7120006Abstract: A switching transformer applies an alternating high voltage across an internal electrode and an external electrode which face each other with a glass tube as a dielectric body between them. The anode side of a diode is connected to the external electrode which is not a voltage supply side electrode, while the cathode side is grounded. When a relay connected to both the terminals of the diode is turned on, substantially equal amounts of positive ions and negative ions are generated, and a bacteria removal/disinfection effect can be obtained by emitting these positive ions and negative ions into the air. When the relay is turned off, a relatively small amount of positive ions and a relatively large amount of negative ions are generated, and a relaxation effect given by negative ions can be obtained by emitting these positive ions and negative ions into the air.Type: GrantFiled: April 19, 2002Date of Patent: October 10, 2006Assignee: Sharp Kabushiki KaishaInventors: Yoshinori Sekoguchi, Kenji Furuhashi, Mamoru Morikawa

The wireless transmitter is used for transmitting a signal representative of data related to operation of the vehicle. A wireless receiver is mounted on a helmet worn by a driver of the vehicle. The receiver receives a transmitted data signal from the transmitter and generates an output signal. A power supply is mounted on the helmet, and comprises a solar cell and a secondary battery for supplying electric power to the receiver. Converter circuits are connected to an output stage of the wireless receiver for converting the output signal of the receiver into a light display signal of visible rays. A display and mirror are mounted on the helmet for projecting and displaying the display signal from the converter circuits in a forward visual field of the driver.Type: GrantFiled: January 22, 1990Date of Patent: December 10, 1991Assignee: Kawajyuu Gifu Engineering Co., Ltd.Inventors: Toshio Hori, Kenji Furuhashi, Makoto Wakita, Kazuo Ueda
