Publication number: 20150043933Abstract: An image forming apparatus includes a sheet feed unit which feeds a sheet to an image forming unit forming an image on the sheet, a re-transport roller which reverses the sheet with a toner image fixed on the sheet and re-transports the sheet to the image forming unit, and a control unit which controls a sheet feed operation of the sheet feed unit for feeding the sheet. As the temperature of the re-transport roller sensed by the temperature sensing unit is decreased, the control unit retards the timing at which the sheet feed unit starts the sheet feed operation when a duplex image formation in which the image is formed on both sides of the sheet is performed after a one-side image formation is completed.Type: ApplicationFiled: October 28, 2014Publication date: February 12, 2015Inventors: Takashi Kuwata, Kenji Abe, Hideki Ohta, Takamichi Matsuo, Youhei Suzuki, Takuro Mita

Publication number: 20150037078Abstract: The present invention provides a fixing device including a flexible cylindrical rotary member and an inner-surface opposing portion that opposes an inner surface of the rotary member at an end portion of the rotary member in a generatrix direction. The inner-surface opposing portion moves upstream in a recording material conveying direction in accordance with lateral shift of the rotary member in the generatrix direction. This restricts the lateral shift of the rotary member.Type: ApplicationFiled: July 28, 2014Publication date: February 5, 2015Inventors: Hideki Ohta, Terutaka Endo, Seiji Obata, Jiro Moriya, Takayuki Mizuta

Patent number: 8426376Abstract: Because AK022567 has angiogenesis inhibitory activity, it is useful as an angiogenesis inhibitor. Furthermore, 4 splicing variants obtained from the same gene are also useful as an angiogenesis inhibitor. These 5 polypeptides, polynucleotides encoding the polypeptides and antibodies against the polypeptides are useful for screening of a candidate compound as an angiogenesis inhibitor or promoter. A compound obtained from the screening is useful as a medicine and can be used for a preventive or therapeutic agent for an angiogenesis related disease.Type: GrantFiled: February 8, 2010Date of Patent: April 23, 2013Assignee: Tohoku Technoarch Co., Ltd.Inventors: Yasufumi Sato, Hikaru Sonoda, Hideki Ohta

Patent number: 8187873Abstract: It is intended to provide a monoclonal antibody that specifically recognizes human soluble LOX-1, particularly a monoclonal antibody with a dissociation constant (Kd) for human soluble LOX-1 of 1×10?9 (M) or less. The antibody can be produced from a hybridoma prepared by a method including the following steps of: (1) immunizing a non-human animal with a prokaryotic cell-derived human LOX-1 extracellular domain; (2) collecting antibody-producing cells from the animal; (3) fusing the antibody-producing cells with myeloma cells; (4) selecting hybridomas that produce a monoclonal antibody reacting with the human LOX-1 extracellular domain from the fused cells obtained in the above step; and (5) selecting a hybridoma that produces a monoclonal antibody reacting with a eukaryotic cell-derived human LOX-1 extracellular domain from the selected hybridomas.Type: GrantFiled: July 27, 2007Date of Patent: May 29, 2012Assignee: Shionogi & Co., Ltd.Inventors: Goro Kominami, Masahiro Nakamura, Noriaki Kume, Hideki Ohta
