Patent number: 8178006Abstract: A fiber aggregate contains fine carbon fibers and fine boron nitride fibers. Desirably the boron nitride fibers form an outer layer portion of the fiber aggregate and the fine carbon fibers form a core portion of the fiber aggregate. Desirably the fine carbon fibers and the fine boron nitride fibers are twisted with each other. Desirably the fine carbon fibers are carbon nanotubes and the fine boron nitride fibers are boron nitride nanotubes. Desirably the fiber aggregate further contains boron-containing fine carbon fibers. The fine boron nitride fibers are formed by substituting carbon atoms of fine carbon fibers by boron atoms and nitrogen atoms. The fiber aggregate is fabricated by mixing a fiber aggregate that contains fine carbon fibers with boron and heating the fiber aggregate mixed with the boron in a nitrogen atmosphere to transform some of the fine carbon fibers into fine boron nitride fibers.Type: GrantFiled: February 20, 2009Date of Patent: May 15, 2012Assignee: DENSO CORPORATIONInventors: Tomohiro Shimazu, Yoshinobu Suzuki, Hisayoshi Oshima

Patent number: 8173212Abstract: A method for manufacturing a carbon nano tube by a CVD method includes: supplying a carbon atom to a catalyzer for forming the carbon nano tube; and controlling an amount of carbon supply with time. In this method, super saturation of the carbon atom in the catalyzer is controlled appropriately. Thus, a caulking layer is prevented from being formed on the catalyzer, and therefore, the carbon nano tube having a sufficient length is obtained.Type: GrantFiled: April 22, 2008Date of Patent: May 8, 2012Assignee: DENSO CORPORATIONInventors: Hisayoshi Oshima, Shinichi Mukainakano

Patent number: 7576512Abstract: A secondary battery charging system, mounted on a vehicle having an internal combustion engine, has a secondary battery, a fuel cell, a fuel storage unit, and a fuel supply controller. In order to start the engine of the vehicle, the engine requires the electric power from the secondary battery. The fuel storage unit stores a fuel to be supplied to the fuel cell. When a given condition is satisfied, the fuel supply controller instructs the fuel storage unit to supply the fuel to the fuel cell in order to start the operation of the engine of the vehicle. The fuel cell thereby starts the generation of the electric power by performing electric chemical reaction and supplies the generated electric power to the secondary battery. The secondary battery supplies the electric power to the engine of the vehicle. The engine initiates its operation.Type: GrantFiled: January 17, 2006Date of Patent: August 18, 2009Assignee: Denso CorporationInventors: Tetsuro Kikuchi, Hiroyuki Usami, Akira Kato, Hisayoshi Oshima

Publication number: 20090117026Abstract: A method for manufacturing a carbon nano-tube by a chemical vapor deposition includes: introducing a carbon source gas into a reaction chamber; growing the carbon nano-tube by using a catalyser; and maintaining a pressure of the carbon source gas in the reaction chamber in a range between 1.0 Torr and 2.0 Torr so that the carbon nano-tube is formed. Since the pressure is maintained in a range between 1.0 Torr and 2.0 Torr, the catalyser is not caulked. Thus, the carbon nano-tube is stably formed.Type: ApplicationFiled: September 30, 2008Publication date: May 7, 2009Applicant: DENSO CORPORATIONInventors: Tomohiro Shimazu, Yoshinobu Suzuki, Hisayoshi Oshima
