Patent number: 9337491Abstract: An electrode for a lithium battery, which electrode includes an electrode active material which can charge and discharge lithium ions (A), a carbonaceous conductive additive (B) and a binder (C). The carbonaceous conductive additive contains carbon fiber, the carbon fiber including a mixture of two kinds of carbon fibers having different diameter distributions on a number basis; and the fiber diameter distribution of the carbon fiber in the electrode has one or more maximum values at 5-40 nm and at 50-300 nm, respectively. Also disclosed is a lithium battery using the electrode. The electrode enables production of a lithium battery having a reduced discharge capacity decline.Type: GrantFiled: February 15, 2012Date of Patent: May 10, 2016Assignee: SHOWA DENKO K.K.Inventors: Ryuji Yamamoto, Yuusuke Yamada, Takeshi Nakamura

Patent number: 9114992Abstract: Provided are carbon fibers with low metal ion elution amount without subjecting to high-temperature heat treatment, in which the metal ion may be sometimes precipitated on an electrode of electrochemical devices such as batteries and capacitors to cause short-circuit. The carbon fibers comprises Fe, at least one catalyst metal selected from the group consisting of Mo and V, and a carrier; wherein the carbon fibers have an R value (ID/IG) as measured by Raman spectrometry of 0.5 to 2.0 and have an electrochemical metal elution amount of not more than 0.01% by mass.Type: GrantFiled: August 22, 2013Date of Patent: August 25, 2015Assignee: SHOWA DENKO K.K.Inventors: Ryuji Yamamoto, Yuusuke Yamada, Takeshi Nakamura

Publication number: 20140370282Abstract: Provided is a method of efficiently producing carbon fibers that can impart sufficient electrical or thermal conductivity to a material even by the addition of a small amount of the carbon fibers. The method of producing carbon fibers involves preparing a catalyst by allowing a carrier composed of silica-titania particles comprising silica in the core and titania in the shell of the particle to support a catalytic element, such as Fe element, Co element, Mo element, or V element, and bringing the catalyst into contact with a carbon element-containing material, such as methane, ethane, ethylene, or acetylene, under heating region at about 500 to 1000° C.Type: ApplicationFiled: December 27, 2012Publication date: December 18, 2014Inventors: Ryuji Yamamoto, Yuusuke Yamada, Takeshi Nakamura

Patent number: 8232358Abstract: Disclosed is a production method of polypropylene having high MFR value and excellent product qualities with high productivity. The method enables to produce a propylene polymer by a gas phase process where the reaction heat is removed mainly by the heat of vaporization of liquefied propylene. The method is characterized by using a solid catalyst component (A) which is prepared by contacting components (A1), (A2) and (A3) shown below. Further disclosed are: a propylene polymer produced by the method; a propylene polymer composition; and a molded body of the composition. Component (A1): a solid component containing titanium, magnesium and a halogen as essential components. Component (A2): a vinyl silane compound. Component (A3): an organosilicon compound having an alkoxy group (A3a) and/or a compound having at least two ether bonds (A3b).Type: GrantFiled: December 18, 2009Date of Patent: July 31, 2012Assignee: Japan Polypropylene CorporationInventors: Yoshitaka Kobayashi, Takanori Nakashima, Yuusuke Yamada, Iku Kouzai, Youichi Maeda, Kouji Nakayama, Keiji Fukuda

Patent number: 6825757Abstract: A vehicle perimeter monitor having a high range-finding performance of a short distance and capable of presenting correct information to a driver is provided. A radar 1 including a transmitting antenna 2 and a receiving antenna 3 is fixed on a support member 8 which is a support member integral with a door mirror 7. Accordingly, even if the driver changed viewing direction of the door mirror 7, the positions the transmitting antenna 2 and the receiving antenna 3 relative to the door mirror 7 are kept constant. Therefore, though a part of the radiated transmit wave may be reflected by the door mirror 7, by measuring the reflected wave by the door mirror 7 beforehand, the reflected wave can be canceled by a signal processing circuit part 5.Type: GrantFiled: April 30, 2001Date of Patent: November 30, 2004Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Yuusuke Yamada
