Patent number: 9079710Abstract: A waste storage device includes a waste storage part for storing a waste item and a packaging device arranged in an upper part of the waste storage part. The packaging device includes two film feed rollers, two waste sealing rollers which pull out films and are arranged in parallel that the peripheral surfaces thereof are in contact via the pulled out respective films in a normal state and at least one of which has the peripheral surface that is elastically deformed along the shape of the waste item, and a driving part which rotates the rollers. Two friction rollers which are driven and rotated to sandwich the films sealing the waste item having passed between the waste sealing rollers and pull them downward are provided below the waste sealing rollers. The device prevents a waste item sealed with resin films from being caught in rollers such as waste sealing rollers.Type: GrantFiled: June 22, 2010Date of Patent: July 14, 2015Assignee: Kyoritsu Seiyaku CorprorationInventor: Yoichi Nakano

Patent number: 8964042Abstract: A first heat radiation unit is formed on one surface of the imaging unit in a vertical direction. A second heat radiation unit is formed on the other surface of the imaging unit in the vertical direction. A third heat radiation unit is formed on a surface opposite to an imaging direction of the imaging unit. A first heat transfer unit transfers heat of a first heat source of the imaging unit to the first heat radiation unit and the third heat radiation unit. A second heat transfer unit transfers heat of a second heat source of the imaging unit, which has a higher maximum allowable temperature than the first heating unit, to the second heat radiation unit. A heat insulation unit suppresses heat transfer between the first and the second heat radiation units and between the third and the second heat radiation units.Type: GrantFiled: October 9, 2013Date of Patent: February 24, 2015Assignee: JVC KENWOOD CorporationInventors: Masayuki Nozawa, Munenobu Nakayama, Yoichi Nakano, Taguchi Hiromi
