Patent number: 11217722Abstract: A hybrid growth method for III-nitride tunnel junction devices uses metal-organic chemical vapor deposition (MOCVD) to grow one or more light-emitting or light-absorbing structures and ammonia-assisted or plasma-assisted molecular beam epitaxy (MBE) to grow one or more tunnel junctions. Unlike p-type gallium nitride (p-GaN) grown by MOCVD, p-GaN grown by MBE is conductive as grown, which allows for its use in a tunnel junction. Moreover, the doping limits of MBE materials are higher than MOCVD materials. The tunnel junctions can be used to incorporate multiple active regions into a single device. In addition, n-type GaN (n-GaN) can be used as a current spreading layer on both sides of the device, eliminating the need for a transparent conductive oxide (TCO) layer or a silver (Au) mirror.Type: GrantFiled: July 11, 2016Date of Patent: January 4, 2022Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Erin C.

Patent number: 9010755Abstract: A printer apparatus has a contact pressure device for flat articles on a continuously moving transport belt, in particular letters in a franking and/or addressing machine. In order to increase the usable region and/or of the throughput of the printer apparatus, flat articles of different thicknesses are processed with predetermined speed, without slippage, in succession with arbitrarily small gaps between successive articles. An elastic, bellows-shaped, resiliently supported air bag has a low-friction, wear-resistant cover surface that is in non-positive contact with the transport belt. With its associated retention and air supply devices the bellows serves as a mobile contact pressure module.Type: GrantFiled: July 18, 2013Date of Patent: April 21, 2015Assignee: Francotyp-Postalia GmbHInventors: Axel Ortmann, Wolfgang Muhl

Patent number: 9010753Abstract: A sheet processing apparatus including a stacking tray that stacks sheets, a conveying member that conveys a sheet to the stacking tray and discharges the sheet bundle from the stacking tray, wherein the conveying member includes a conveying roller and a conveying belt stretched by a plurality of stretch rollers, and a sheet processor that performs predetermined processing to the sheet bundle. When the conveying member conveys the sheet to the stacking tray, a part of the conveying belt that is not wound on the stretch roller contacts the conveying roller by moving the conveying belt as such a nip for conveying the sheet is formed. When the conveying member discharges the sheet bundle from the stacking tray, a part of the conveying belt that is wound on the stretch roller contacts the conveying roller by moving the conveying belt so that a nip for conveying the sheet is formed.Type: GrantFiled: May 15, 2014Date of Patent: April 21, 2015Assignee: Ricoh Company, Ltd.Inventors: Yuusuke Shibasaki, Nobuyoshi Suzuki, Shingo Matsushita, Katsuhiro Kosuge, Ryuji Yoshida, Wataru Takahashi, Takashi Saito, Akihiro Musha, Takuya Morinaga, Ikuhisa Okamoto

Publication number: 20150102555Abstract: A sheet conveyance apparatus includes a conveyance roller pair, an urging portion, a releasing portion, and a moving portion. The conveyance roller pair includes a first roller and a second roller, and conveys a sheet. The urging portion applies a pinching force to the conveyance roller pair. The releasing portion releases the pinching force of the conveyance roller pair against an urging force of the urging portion. The moving portion moves the conveyance roller pair, the urging portion, and the releasing portion in a width direction intersecting with a sheet conveyance direction.Type: ApplicationFiled: October 10, 2014Publication date: April 16, 2015Inventor: Kouhei Deno

Patent number: 9004488Abstract: A conveying apparatus includes a first pair of rollers having a drive roller and a pinch roller driven by the drive roller, a second pair of rollers provided downstream of the first pair of rollers, and an arm member supporting the drive roller and adapted to be swingable such that a force for pressing the drive roller against the pinch roller increases as a conveyance resistance of the sheet increases. The force for pressing the drive roller against the pinch roller decreases if driven by the moving sheet. The conveying speed of the second pair of rollers is set to be higher than the conveying speed of the drive roller so as to cause the drive roller to be driven by the sheet in the case where a skew of the sheet has been corrected and the sheet having the skew corrected is conveyed by the second pair of rollers.Type: GrantFiled: August 6, 2012Date of Patent: April 14, 2015Assignee: Canon Kabushiki KaishaInventor: Hideyuki Terashima

Patent number: 8998206Abstract: A medium transport direction switching mechanism may be provided of a simple configuration which is capable of switching the transport direction of a transported information recording medium. One end may be a biasing member for biasing a pinch roller toward a transport roller engages a support shaft which supports the pinch roller, whereas the other end of the biasing member engages a retaining member which retains the support shaft. In the medium transport direction switching mechanism, rotational behavior of the pinch roller centering upon a rotational center of the transport roller is possible between a first facing position and a second facing position, wherein the pinch roller moves to the first facing position when the transport roller rotates positively, and moves to the second facing position when the transport roller rotates negatively.Type: GrantFiled: July 1, 2011Date of Patent: April 7, 2015Assignee: Nidec Sankyo CorporationInventor: Chisato Hiyama

Patent number: 8991822Abstract: A conveyor device includes a conveyor including a conveyor roller to convey a sheet along a conveyance path, a cover movable between a closed position where the cover covers the conveyor roller and an open position where the cover is separated from the conveyor roller. The conveyor further includes a pinch roller urged toward the conveyor roller when the cover is in the closed position. When the cover is in the closed position, the conveyor roller and the pinch roller define a nip point along the conveyance path. The conveyor device includes a holder supported by the cover and to rotatably support the pinch roller and an urging member disposed between the cover and the holder to move the holder away from the cover to urge the pinch roller toward the conveyor roller when the cover is in the closed position.Type: GrantFiled: September 27, 2013Date of Patent: March 31, 2015Assignee: Brother Kogyo Kabushiki KaishaInventors: Daisuke Kozaki, Takashi Ohama, Ai Oyamada, Takeru Morinaga
