Publication number: 20240136102Abstract: A winding of a transmission coil included in a power transmission device of a contactless power feed apparatus and serving to transmit AC power to a power reception device contactlessly is formed of a wiring pattern provided on a substrate. The transmission coil is divided into partial coils arranged coaxially. Each of the partial coils is formed such that, among the partial coils, a number of turns of a winding included in a partial coil is larger as the partial coil is located more outwardly.Type: ApplicationFiled: September 6, 2023Publication date: April 25, 2024Applicant: OMRON CorporationInventors: Goro NAKAO, Yuki ITO, Taichi MISHIMA, Yusuke KAWAI, Hiroyuki IBUKI, Yoshihisa ISHIKAWA

Patent number: 8843003Abstract: An image forming apparatus includes an image holding member, a transfer unit, a fixing unit, a transport unit, a transfer-performance-detection toner image forming unit, a density detection unit, and a selector. A toner image is held on the image holding member. The transfer unit transfers the toner image onto a recording medium. The fixing unit fixes the toner image onto the recording medium. The transport unit reverses the recording medium onto which the toner image has been fixed, and transports the reversed recording medium back to the transfer unit. The transfer-performance-detection toner image forming unit forms plural transfer-performance-detection toner images with different transfer settings of the transfer unit. The density detection unit detects densities of plural transfer-performance-detection toner images. The selector selects a transfer setting of the transfer unit in accordance with a detection result obtained by the density detection unit.Type: GrantFiled: February 27, 2012Date of Patent: September 23, 2014Assignee: Fuji Xerox Co., Ltd.Inventor: Yoshihisa Nakao
