Publication number: 20110314796Abstract: A particulate matter (PM) detection sensor is placed in an exhaust gas pipe of a diesel engine. The PM sensor element has a detection part composed of a pair of detection electrodes and a heater part. The detection electrodes and the heater part are stacked in the PM sensor element. A control circuit instructs a heater power supply to supply electric power to the heater part when the diesel engine is started to operate. The heater part heats the detection part at a predetermined temperature T1 within a range of 600° C. to 900° C. for a predetermined period S1 of time, for example, 650° C. for 20 seconds, in order to burn and completely eliminate particulate matter accumulated in the detection part. This control process avoids incorrect detection of the PM detection sensor. After this process, the control circuit executes usual control of the PM detection sensor.Type: ApplicationFiled: June 28, 2011Publication date: December 29, 2011Applicant: DENSO CORPORATIONInventors: Satoshi NAKAMURA, Shinya Teranishi, Hirofumi Takeuchi, Takashi Sawada, Hideaki Itoh

Patent number: 7691216Abstract: A melt of a hydrogen storage alloy having an arbitrary composition is cooled gradually at a cooling rate of 5° C./min or less and solidified. Alternatively an alloy having an arbitrary composition, after heating to a temperature equal to or more than a melting point thereof, is cooled gradually at a cooling rate of 5° C./min or less and solidified. Thereby a homogeneous alloy reduced in segregation, precipitates, or inclusions is obtained. The homogeneous alloy is excellent in the hydrogen storage amount, in the plateau property and in durability.Type: GrantFiled: March 24, 2003Date of Patent: April 6, 2010Assignee: The Japan Steel Works, Ltd.Inventors: Hironobu Arashima, Takashi Ebisawa, Hideaki Itoh
