Publication number: 20160163494Abstract: To provide a magnetron improved in high efficiency and load stability while suppressing costs. By shortening the height of vane Vh so that the ratio of the height of vane Vh to a gap between end hats EHg (EHg/Vh) satisfies a condition 1.12?EHg/Vh?1.26, an input side pole piece-vane gap IPpvg becomes larger than an output side pole piece-vane gap OPpvg, and an input side end hat-vane gap IPevg becomes larger than an output side end hat-vane gap OPevg, load stability at high efficiency can be improved while shortening the height of vane Vh. Therefore, it is possible to provide a magnetron improved in high efficiency and load stability while suppressing costs.Type: ApplicationFiled: November 24, 2015Publication date: June 9, 2016Applicant: Toshiba Hokuto Electronics CorporationInventor: Naoya Kato

Patent number: 7370642Abstract: A CPU measures an actual air-fuel ratio based on the signals detected by the air-fuel ratio sensor. When the difference between the actual air-fuel ratio and a target air-fuel ratio is larger than a predetermined value, the computer determines that a fuel vapor amount purged into the intake passage deviates from a target value due to an incorrectness of a reference flow quantity of the purge valve. The computer calculates an actual reference flow quantity based on a measured actual air-fuel ratio, and rewrites the reference flow quantity corresponding to a current intake pressure into the calculated the reference flow quantity. Thereby, the difference between the actual air-fuel ratio and the target air-fuel ratio can be reduced.Type: GrantFiled: October 19, 2006Date of Patent: May 13, 2008Assignees: Denso Corporation, Nippon Soken, Inc.Inventors: Noriyasu Amano, Naoya Kato, Masao Kano, Shinsuke Takakura

Publication number: 20070074708Abstract: A PCV valve is arranged in an outflow passage. An ECU controls rotation of a motor such that an opening degree of the PCV valve increases in response to an increase in an opening degree of a throttle valve. The outflow passage connects an interior of a head cover of an engine to a portion of an intake air passage located on a downstream side of the throttle valve. The outflow passage recirculates blow-by gas leaked from a combustion chamber into an interior of a crankcase to the portion of the intake air passage located on the downstream side of the throttle valve. An inflow passage connects the interior of the head cover to a portion of the intake air passage located on an upstream side of the throttle valve. The inflow passage conducts intake air from the intake air passage to the interior of the head cover.Type: ApplicationFiled: September 29, 2006Publication date: April 5, 2007Applicants: DENSO CORPORATION, NIPPON SOKEN, INC.Inventors: Noriyasu Amano, Hideaki Itakura, Naoya Kato, Kazuhiro Hayashi, Hidetoshi Uchiyama

Patent number: 7158673Abstract: An image-processing apparatus for processing the image data input from an image-handling device and then outputting the image data to another image-handling device. The apparatus comprises a black-adaptation correction device. The black-adaptation correction device corrects the image data in consideration of the fact that adaptation to black varies from person to person, if the darkest points of the image-handling devices differ from each other. Since the image is so corrected, the colors of the images produced by the image-handling devices look almost the same in spite of the fact that the darkest points of the image-handling devices differ from each other.Type: GrantFiled: March 23, 2005Date of Patent: January 2, 2007Assignee: Sony CorporationInventors: Kiyotaka Nakabayashi, Naoya Kato

Patent number: 6988391Abstract: A fuel vapor leakage inspection apparatus utilizes a fuel tank, an adsorption container which houses an adsorbent for adsorbing fuel vapor generated in the fuel tank, and an exhaust device for communicating between the adsorption container and an intake pipe. Furthermore, the apparatus utilizes a pressure means that pressurizes or depressurizes a fuel vapor path formed from the fuel tank through the adsorption container to the exhaust device. A leakage detection means detects leakage from the fuel vapor path after the fuel vapor path is pressurized or depressurized by the pressure means while a calculation means calculates an amount of fuel vapor adsorbed, and a control means determines if the pressure means should execute leakage inspection of the fuel vapor path in accordance with the amount of the fuel vapor calculated by the calculation means.Type: GrantFiled: June 2, 2005Date of Patent: January 24, 2006Assignees: Nippon Soken, Inc., Denso CorporationInventors: Noriyasu Amano, Naoya Kato, Hideaki Itakura, Masao Kano

Patent number: 6966215Abstract: An apparatus detects leak in a fuel vapor treatment system which is referred to as an evaporation system. The apparatus measures a required time T2 that is required for decreasing pressure in the evaporation system from P0 to P1 while opening a base leak hole that provides known amount of leak. Then, a required time T1 that is required for decreasing pressure from P0 to P1 is measured while closing the base leak hole. The apparatus compares the required times T1 and T2 in order to detect a leak other than the base leak hole. In this process, a specified coefficient that is defined in accordance with the base leak hole is taken into consideration. It is possible to detect the leak of the evaporation system with high accuracy even when the amount of remaining fuel is extremely large.Type: GrantFiled: October 15, 2004Date of Patent: November 22, 2005Assignees: Nippon Soken, Inc., Denso CorporationInventors: Noriyasu Amano, Hideaki Itakura, Naoya Kato, Masao Kano
