Publication number: 20180288255Abstract: An image forming apparatus includes an image reading unit, an original conveyance unit, a reversing unit, an image forming unit, an image forming conveyance unit, and a control unit. The original conveyance unit conveys an original in a first direction toward the image reading unit, which reads an image of the original. The reversing unit conveys an original passing through the image reading unit in the first direction, or reversely conveys the original toward the image reading unit in a second direction. The image forming unit forms an image on a sheet. The image forming conveyance unit conveys, to the image forming unit, an original reversely conveyed by the reversing unit via the image reading unit. The control unit controls an operation for reading an image of the original by using the image reading unit and for overprinting the original with an image by using the image forming unit.Type: ApplicationFiled: March 7, 2018Publication date: October 4, 2018Inventors: Yoshitaka Zaitsu, Kazushi Suzuki, Hideki Ohta, Tamotsu Kaneko

Publication number: 20180239281Abstract: 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: April 24, 2018Publication date: August 23, 2018Inventors: Hideki Ohta, Terutaka Endo, Seiji Obata, Jiro Moriya, Takayuki Mizuta

Patent number: 9454113Abstract: 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: GrantFiled: October 28, 2014Date of Patent: September 27, 2016Assignee: Canon Kabushiki KaishaInventors: Takashi Kuwata, Kenji Abe, Hideki Ohta, Takamichi Matsuo, Youhei Suzuki, Takuro Mita

Publication number: 20160047812Abstract: A method for detecting a colorectal cancer, including the steps of measuring an amount of exosomes expressing CD147 in a body fluid sample derived from a test individual with an anti-CD147 monoclonal antibody or a fragment thereof; and comparing a signal intensity of exosomes in the step with a signal intensity in a control individual, wherein a case where the signal intensity in the test individual is found to be stronger than the signal intensity in the control individual serves as an index of the presence of the colorectal cancer. According to the method of the present invention, whether or not a sample provider has a high possibility of developing a colorectal cancer can be judged. Therefore, the method is useful because the sample provider can take a means of inhibiting the progression of cancer.Type: ApplicationFiled: March 19, 2014Publication date: February 18, 2016Applicants: THEORIA SCIENCE INC., SHIONOGI & CO., LTD.Inventors: Hideki OHTA, Hiroyuki OKAMOTO, Hikaru SONODA, Takahiro OCHIYA
