Patent number: 8706382Abstract: The disclosure provides a control device of a spark-ignition gasoline engine. When an operating state of an engine body is within a low engine speed range, a controller controls a fuel pressure variable mechanism so that a fuel pressure is higher within a high engine load range compared to a low engine load range, the controller operates, within the high engine load range, a fuel injection valve to perform a fuel injection at least at a timing that is more retarded than an injection timing of a fuel within the low engine load range and is within a retard period from a late stage of a compression stroke to an early stage of an expansion stroke, and the controller operates, within the high engine load range, an ignition plug to ignite at a timing within the retard period and further after the fuel injection.Type: GrantFiled: February 7, 2012Date of Patent: April 22, 2014Assignee: Mazda Motor CorporationInventors: Shuji Oba, Kouhei Iwai, Kazuhiro Nagatsu, Masahisa Yamakawa, Noriyuki Ota, Naoya Watanabe, Hiroyuki Kurita, Tatsuya Fujikawa, Kenji Uchida, Daisuke Asaji, Takaaki Nagano

Patent number: 8441828Abstract: The present invention provides a content addressable memory capable of higher frequency operation than conventional. When a search enable signal supplied from a search control circuit is asserted, each of search line drivers transfers search data to each CAM cell of a CAM memory array via a search line pair. The search line enable signal is transmitted to the search line drivers via a single control signal line coupled to the search control circuit. The control signal line is coupled to the search line drivers in such a manner that the search line enable signal passes through coupling nodes between the search line drivers and the control signal line in an arrangement order of the search line drivers from the side far away as viewed from match amplifiers.Type: GrantFiled: June 28, 2012Date of Patent: May 14, 2013Assignee: Renesas Electronics CorporationInventor: Naoya Watanabe

Publication number: 20120234942Abstract: A spray gun (1) forms a desired spray pattern by atomizing by means of atomizing air (A) a spray liquid which is sprayed from a liquid ejection port (44) opened/closed by a needle valve (4), and jetting pattern air (P) to the flow of spray mist of the atomized spray liquid. A nozzle taper angle (?1) is set in a range of 5° to 15°, and a cap taper angle (?2) is set in a range of 20° to 40°. Atomizing air (A) is jetted from a nozzle insertion hole (58) toward the center of a nozzle (3). Pattern air (P) is jetted in a spreading suppressed region (R) wherein the flow of the spray mist does not spread over an area greater than or equal to a predetermined cross-sectional area, to the flow of spray mist, and as a result, the spray mist is more uniformly sprayed over a wide range.Type: ApplicationFiled: October 19, 2010Publication date: September 20, 2012Applicants: Chevron U.S.A Inc., The Regents of the University of CaliforniaInventors: Kazuomi Unosawa, Shigemi Isobe, Takerou Adachi, Hirotsune Yasumi, Kouji Fukuda, Naoya Watanabe
