Patent number: 9487370Abstract: A sheet material conveying device includes: a sheet material housing unit; a sheet material conveying unit that conveys each sheet material to a predetermined conveyance target position; a separating/feeding unit that separates a sheet material from sheet materials in the sheet material housing unit and conveys the separated sheet material alone to the sheet material conveying unit; a multi-feed detecting unit that detects whether multi-feed occurs in which a plurality of sheet materials are fed from the separating/feeding unit to the sheet material conveying unit; and an internal sheet material detecting unit that detects presence of the sheet material in the sheet material conveying unit. The sheet material conveying device performs multi-feed failure detection control for detecting whether a failure occurs in the multi-feed detecting unit before notification of a detection result of the internal sheet material detecting unit.Type: GrantFiled: August 18, 2014Date of Patent: November 8, 2016Assignee: RICOH COMPANY, LIMITEDInventors: Hiroaki Utagawa, Takanori Ohta, Takashi Nakano, Takashi Fukumoto, Kenji Hayasaka, Joji Akiyama, Masataka Fukuchi

Patent number: 8211472Abstract: A suspension of ascorbic acid in glycerol or in glycerol comprising diglycerol, in which the content of ascorbic acid is 13% by mass or greater, and further in which 8 to 12% by mass of the ascorbic acid is dissolved in glycerol or in glycerol comprising diglycerol, and the rest of ascorbic acid is precipitated in the form of microcrystals having a particle diameter of 25 ?m or smaller and is uniformly dispersed in the suspension. The suspension of ascorbic acid in glycerol is useful as a base material for cosmetics containing ascorbic acid which exhibits excellent feel in the use (spreadability and smooth feel on application to the skin).Type: GrantFiled: October 18, 2007Date of Patent: July 3, 2012Assignee: Market Styles Co., Ltd.Inventors: Mikiharu Okumura, Takanori Ohta

Patent number: 5197172Abstract: A machining system comprising a plurality of different kinds of single purpose machining units arranged at plural machining stations located along a transfer path, and a transfer apparatus for transferring plural kinds of workpieces along the transfer path so as to position each of the workpieces at plural machining stations successively for machinings by the plural single purpose machining units. The machining system is provided with a return conveyor or a transfer vehicle for transferring the workpieces along a return path from the end of the transfer path to a workpiece unloading station, and a numerically controlled general purpose machine tool arranged adjacent to the return path. The general purpose machine carries out special machinings which cannot be carried out by the single purpose machining units for machining some workpieces which require such special machinings.Type: GrantFiled: May 29, 1992Date of Patent: March 30, 1993Assignee: Toyoda Koki Kabushiki KaishaInventors: Masayoshi Takagi, Takehito Aikawa, Takanori Ohta, Ryoichi Takami, Hiroki Osada

Patent number: 4831349Abstract: A switching device suitable for use on vehicles as a window regulator switch or a sunroof regulator switch. The switching device comprises a solenoid unit including a yoke, a core and a coil, a first card attached to the core so as to be pressed against a contact for supplying current to the coil of the solenoid unit and to an external load such as a motor, to keep the contact closed while the core is attracted to the yoke, a second card disposed for movement in parallel to the direction of movement of the first card, a pivotally supported operating knob having an operating arm connected to the second card, and a returning mechanism for biasing the operating knob toward the neutral position to return the operating knob to the neutral position when released. When the operating knob is turned to a manual operating position the contact is closed temporarily and is opened when the operating knob is released.Type: GrantFiled: June 20, 1988Date of Patent: May 16, 1989Assignees: Toyota Jidosha Kabushiki Kaisha, Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Hisashi Hirose, Takanori Ohta, Shigeo Hara, Kazuo Iwata

Patent number: 4554811Abstract: A crankpin rolling apparatus is provided wherein plural pairs of upper and lower arms are pivotably carried by respective hinge pins extending in parallel relation with the rotational axis of a workpiece support device. A pair of upper and lower roller holders each rotatably carrying burnishing rollers are respectively mounted on each pair of the upper and lower arms. When the plural pairs of upper and lower arms are closed by respective pressuring actuators, the pair of upper and lower roller holders arrest a corresponding one of crankpins of a crankshaft on the workpiece support means and pressure the burnishing rollers upon fillets formed on the corresponding one of crankpins. The hinge pins are respectively carried by a plurality of rocking members, which are independently pivotable about a support shaft held by a machine frame in parallel relation with the rotational axis of workpiece support device.Type: GrantFiled: August 4, 1983Date of Patent: November 26, 1985Assignee: Toyoda Koki Kabushiki KaishaInventors: Takehiko Hayashi, Hiroyuki Ikuta, Takanori Ohta
