Patent number: 9052650Abstract: A fixing device fixes a toner image on a recording medium by heating the recording medium, with a heating area and a non-heating area selected in accordance with a magnetic flux and a repulsive magnetic flux. The fixing device includes a heat generating layer, an exciting coil, and a demagnetizing member. The heat generating layer generates heat. The exciting coil generates the magnetic flux, and thereby inductively heats the heat generating layer. The demagnetizing member faces the heat generating layer in the non-heating area. The demagnetizing member generates the repulsive magnetic flux against the magnetic flux generated by the exciting coil, and thereby demagnetizes the magnetic flux and suppresses the heating. Further, the demagnetizing member has a demagnetization effect different between at least a portion of the non-heating area adjacent to the heating area and the remaining portion of the non-heating area.Type: GrantFiled: November 7, 2012Date of Patent: June 9, 2015Assignee: Ricoh Company, Ltd.Inventors: Motoyoshi Yamano, Jun Okamoto, Tetsuo Tokuda, Takashi Sakamaki, Satoshi Ueno, Naoto Suzuki, Fumihiro Hirose

Patent number: 8988204Abstract: A communication unit periodically transmits a request signal toward a prescribed range. When a transmitter exists in the range where the request signal can be received, it sends identification information in a responsive manner. A comparison ECU compares the identification information provided from the communication unit with a predetermined value, and if both of them match with each other, notifies a matching notification to a power source management ECU. On receipt of the matching notification from the comparison ECU, the power source management ECU notifies a lighting-up request for providing an instruction for lighting-up of a light-emitting unit to a body ECU. Upon receipt of the lighting-up request, the body ECU activates a lighting-up command LON. As a result, the light-emitting unit is lit up and notifies a user of the position of a charging port.Type: GrantFiled: July 9, 2013Date of Patent: March 24, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Naoto Suzuki, Motohiro Nakashima
