Patent number: 8762034Abstract: There are provided calculating a differential pressure deposition amount of PM deposited in a DPF based on an exhaust gas flow rate and a differential pressure of the DPF, calculating a model deposition amount of the PM using a model in which a PM amount burned in the DPF is subtracted from the PM amount, calculating a time change rate of the differential pressure deposition amount, and setting a first coefficient to be larger than a second coefficient when the exhaust gas flow rate exceeds a predetermined value and setting the first coefficient to be small when the exhaust gas flow rate exceeds the predetermined value and the time change rate is a predetermined threshold or more when multiplying the differential pressure deposition amount and the model deposition amount by the first and second coefficients, respectively, and calculating an addition value of the respective multiplied values as the PM deposition amount.Type: GrantFiled: February 23, 2012Date of Patent: June 24, 2014Assignee: Komatsu Ltd.Inventors: Hideo Oguri, Akikazu Miyahara

Patent number: 8609342Abstract: The invention provides a reporter gene assay method by which the sex hormone-like activity inherent in a test substance can be accurately assayed excluding the effects caused by a decrease in cell activity (protein expressing capacity). The assay method is a reporter gene assay method using luciferase-expressing cells which comprises further transferring a GFP gene into the luciferase-expressing cells, measuring the luciferase expression level and GFP expression level, and making a judgment about the thus-measured luciferase expression level using the decrease in GFP expression level as an indication of the decrease in cell activity.Type: GrantFiled: December 13, 2002Date of Patent: December 17, 2013Assignee: Otsuka Pharmaceutical Co., Ltd.Inventors: Mitsuru Iida, Hideo Oguri

Patent number: 4889080Abstract: A cylinder head for an internal combustion engine includes a plurality of cooling water passages through which cooling water for cooling the cylinder head is injected. Each of the cooling water passages is so arranged that cooling water injected therethrough is caused to unidirectionally swirl around an outer wall for a fitting hole through which a fuel injection nozzle is fitted. Thus, there is no fear that stagnation of water stream due to collision of water streams flowing around the outer wall for the fuel injection fitting hole occurs or bubbles are produced. This leads to reduction of resistance against flowing of cooling water whereby a cooling efficiency of cooling water for the cylinder head can be increased.Type: GrantFiled: May 24, 1988Date of Patent: December 26, 1989Assignee: Kabushiki Kaisha Komatsu SeisakushoInventor: Hideo Oguri
