Patent number: 7595761Abstract: A door mirror device includes an antenna and a metal frame for attaching parts. The antenna is capable of at least one of receiving radio transmissions from the outside of a vehicle cabin or transmitting radio transmissions to the outside of the vehicle cabin. The antenna includes a plate and a case that are electrically continuous with a matching-use base plate. The plate and the case of the antenna are fixed to the frame by a tapping screw. The antenna is grounded to the frame as a result of the plate becoming electrically continuous with the frame via the tapping screw.Type: GrantFiled: March 22, 2006Date of Patent: September 29, 2009Assignees: Kabushiki Kaisha Tokai-Rika-Denki-Seisakusho, Toyota Jidosha Kabushiki KaishaInventors: Terukazu Hiroe, Nana Nakajima, Hiroaki Kojima, Satoshi Ito, Nobuhiro Ide

Publication number: 20090229579Abstract: An engine-start is inhibited when a gas engine is tilted, and the engine is immediately stopped. A shutoff valve (21) is provided on a liquefied fuel passage (15) supplying a liquefied fuel to a vaporizing chamber (14) from a cylinder (16). The shutoff valve (21) is provided with a diaphragm (28) to which a pulsation pressure of a crank chamber (4) is applied, and opens the liquefied fuel passage (15) if a negative pressure is applied to the diaphragm (28). A tilting shutoff valve (39) is provided in a pressure passage (34) transmitting the pulsation pressure to the shutoff valve (21). The tilting shutoff valve (39) which has a ball valve releases the pulsation pressure of the crank chamber (4) to an atmospheric air. If the pulsation pressure is open to the atmospheric air, the diaphragm (28) can not operate. Accordingly, the liquefied fuel passage 15 is kept being shut off, and is rapidly shut off in response to the tilt during the operation.Type: ApplicationFiled: September 14, 2006Publication date: September 17, 2009Applicant: HONDA MOTOR CO., LTD.Inventors: Masanori Fujinuma, Eiichi Utsugi, Hiroaki Kojima

Patent number: 7554412Abstract: A phase locked loop (PLL) circuit automatically corrects the offset of the analog (especially active type) loop filter to improve the stability and precision of the locked clock or frequency signals. In addition to the general PLL circuit configuration having active type loop filter (30), the PLL circuit also has a frequency comparing circuit (42), a DAC controller (44) and a DAC (digital-to-analog converter) (46). In an offset measurement mode, the outputs of phase error detecting circuit (12, 14) and frequency error detecting circuit (18, 20) are cut, respectively, to establish locking in offset measurement locked loop (42, 44, 45, 30, 40). In this case, offset correction code (EDs) are identified and held. In normal mode, DAC controller (44) has offset correction code (ED) input to DAC (46), and DAC (46) sends offset correction signal (EAs) to loop filter (30).Type: GrantFiled: August 22, 2005Date of Patent: June 30, 2009Assignee: Texas Instruments IncorporatedInventors: Hiroaki Kojima, Isamu Matsushima

Patent number: 7265725Abstract: A cutout portion through which one end side of a U-shaped portion of the antenna passes is cut deeper than a preset passing position where the U-shaped portion passes through the cutout portion. Further, an open dimension of a through hole through which the other end side of the U-shaped portion passes is substantially twice an outer diameter dimension of the U-shaped portion. When the U-shaped portion is passed through the through hole at the preset passing position, the U-shaped portion passes through the substantial center of the through hole. When error arises in the retention position of the antenna and the fixing position of the base plate, the U-shaped portion is displaced inside the cutout portion and the through hole, and the above error is absorbed.Type: GrantFiled: March 22, 2006Date of Patent: September 4, 2007Assignees: Kabushiki Kaisha Tokai-Rika-Denki-Seisakusho, Toyota Jidosha Kabushiki KaishaInventors: Nana Nakajima, Hiroaki Kojima

Patent number: 6806958Abstract: A method and an apparatus for measuring the microforce acting between a micro particle fixed on the probe and the observation plane are described. The probe is feedback-controlled to be held motionless by canceling probe displacements caused by movements of the micro particle fixed on the probe, using irradiation pressure provided by a laser that applies photon pressure. The microforce acting between the micro particle fixed on the probe and the observation plane is measured by recording the time-varying laser output power. This allows probe fluctuations to be reduced to a few angstroms, and permits control of the distance to the target object to within a few nm, enabling measurement of microforces on the order of 0.1 pN.Type: GrantFiled: October 2, 2002Date of Patent: October 19, 2004Assignee: National Institute of Information and Communications Technology, Independent Administrative InstitutionInventors: Hiroaki Kojima, Kazuhiro Oiwa, Brenner Bernhard
