Publication number: 20060150619Abstract: Exhaust passage control valve 10 may comprise housing 30, valve member 20, and helical torsion spring 40. Housing 30 has an exhaust passage. Exhaust gas from an internal combustion engine flows through the exhaust passage of the housing 30. Valve member 20 opens and closes the exhaust passage of the housing. Helical torsion spring 40 may be disposed at the opposite side of the valve member from the housing side thereof. Helical torsion spring 40 comprises a coil part wherein spring wires have been wound in a coil shape, and arms formed at both ends of the coil part. The coil part may be disposed at approximately the center of the valve member. When the arms bend with respect to the coil part, the counter-force of this bending energizes the valve member towards a closing side. The spring mounting member may be arranged and constructed to adjust a position in which the spring mounting member is mounted on the housing such that a rotation angle of the arms can be changed.Type: ApplicationFiled: December 30, 2005Publication date: July 13, 2006Applicants: CHUO HATSUJO KABUSHIKI KAISHA, SAKAMOTO INDUSTRY CO., LTD.Inventors: Hiroyuki Shiga, Shouji Ichikawa, Tatsuhiro Nagashima, Hiroshi Ogura

Publication number: 20050209769Abstract: A traffic management system manages, distributes, and controls various traveling states of vehicles at a high quality level. A vehicle-mounted unit performs an interconnection process for user authentication when entering a predetermined radio-wave zone. A radio unit disposed on a road sends interconnection process completion information to a center device when the interconnection process for connection to the vehicle is completed. If the vehicle does not connect to the radio unit after elapsed of a predicted time at which the vehicle is expected to travel across the radio unit, then the radio unit sends an overtime to the center device. The interconnection process completion information is received, the center device calculates a predicted time at which the vehicle is expected to pass across a radio unit, and sends the predicted time to the radio unit. When the overtime is received, the center device determines whether a fault has occurred or not.Type: ApplicationFiled: September 1, 2004Publication date: September 22, 2005Inventors: Kiyohide Yamashita, Yuji Nagano, Yuji Nomura, Hiroshi Ogura, Kazuyoshi Nagai, Takato Ohashi, Kanna Okamura

Publication number: 20040200067Abstract: A method of machining a glass substrate using a laser, in which a low-permittivity, low-dielectric-loss glass substrate, capable of coping with mass production, is made applicable as the substrate of a high-frequency circuit intended in particular for microwave and millimeter-wave bands. For that purpose, a glass substrate is provided in which the amount of air bubbles in glass is arbitrarily controlled to improve the workability of the substrate. Then, the glass substrate is machined by being irradiated with a pulsed laser a plurality of times, thereby improving the machining shape of the glass substrate. Since glass substrates which are typically difficult to machine can be easily applied to the fabrication of high-frequency circuits, it becomes possible to supply high-performance circuits and apparatuses widely to the public.Type: ApplicationFiled: May 4, 2004Publication date: October 14, 2004Applicant: Masushita Electric Industrial Co., Ltd.Inventors: Hiroshi Ogura, Yuji Hashidate, Hiroyoshi Yajima, Yoshikazu Yoshida

Patent number: 6791438Abstract: A rectangular penetration hole is formed opening in the opposite two main surfaces of a first dielectric substrate. Conductors for grounding are respectively formed on the main surfaces, to cover the openings of the penetration hole. A conductor layer is formed on opposite inner walls in the penetration hole of the dielectric substrate. A waveguide is structured by a space surrounded by the conductors and the conductor layers. The waveguide is magnetically coupled with an input/output line on a second dielectric substrate through a coupling slot. Because a waveguide has walls made continuous in the dielectric substrate, a low-loss waveguide can be realized. Hence, a high-performance radio frequency module can be realized.Type: GrantFiled: October 28, 2002Date of Patent: September 14, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kazuaki Takahashi, Suguru Fujita, Hiroshi Ogura
