Patent number: 10054833Abstract: Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and/or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition.Type: GrantFiled: May 4, 2017Date of Patent: August 21, 2018Assignee: View, Inc.Inventors: Sridhar Karthik Kailasam, Robin Friedman, Anshu A.

Patent number: 10054870Abstract: A surface-emitting laser includes an active layer on which a spacer layer is disposed, and a reflection mirror disposed on the spacer layer, including a current constriction layer that is a selectively-oxidized layer having been selectively oxidized. The current constriction layer is disposed at a position of a node of a standing-wave of an electric field of light oscillated at the active layer and is disposed away from an interface between the spacer layer and the reflection mirror by an optical distance of one-fourth of an oscillation wavelength at the active layer. The selectively-oxidized layer is made of AlGaAs. The reflection mirror includes at least one AlGaInP layer contacting the selectively-oxidized layer.Type: GrantFiled: November 30, 2016Date of Patent: August 21, 2018Assignee: RICOH COMPANY, LTD.Inventors: Shinichi Harada, Naoto Jikutani, Kazuma Izumiya, Yusuke Okura

Patent number: 10054871Abstract: According to an embodiment, an image forming apparatus includes a housing, a developing roller, and a photosensitive drum. The developing roller includes an image area and a pair of non-image areas. The image area extends along an axial direction the developing roller. The non-image areas are provided on both sides in the axial direction with respect to the image area. The image forming apparatus further includes a regulating member. The regulating member covers a gap in positions which are aligned over the non-image area. The regulating member regulates air flow toward sides of the image area in the axial direction.Type: GrantFiled: March 2, 2018Date of Patent: August 21, 2018Assignees: KABUSHIKI KAISHA TOSHIBA, TOSHIBA TEC KABUSHIKI KAISHAInventor: Nobuaki Takahashi

Patent number: 10054872Abstract: An image forming apparatus includes first and second image forming portions. A first conveying pipe conveys a first developer discharged from a first developing unit to a collection portion, and a second conveying pipe conveys a second developer discharged from a second developing unit to the collection portion. A first detection unit detects a toner content of the first developer in the first conveying pipe, and a second detection unit detects a toner content of the second developer in the second conveying pipe. The first developing unit can be removed from the image forming apparatus in a state that the first conveying pipe and the first detection unit remain in the image forming apparatus, and the second developing unit can be removed from the image forming apparatus in a state that the second conveying pipe and the second detection unit remain in the image forming apparatus.Type: GrantFiled: February 23, 2017Date of Patent: August 21, 2018Assignee: CANON KABUSHIKI KAISHAInventor: Osamu Ariizumi

Patent number: 10054873Abstract: A system with a container including a protrusion, and a receiver to receive the container. The receiver includes a slide block that is movable relative to a body of the receiver, the slide block including two surfaces, a first surface, initially contacted by the protrusion of the container during insertion of the container into the receiver, having a first slope to resist movement of the container towards the receiver, and a second surface, subsequently contacted by the protrusion of the container during the insertion of the container into the receiver, having a second slope to interact with the protrusion of the container to assist movement of the container towards the receiver. This construction provides the user with a changing insertion force to indicate proper mounting of the container.Type: GrantFiled: September 19, 2017Date of Patent: August 21, 2018Assignee: RICOH COMPANY, LTD.Inventors: Nobuo Takami, Noriyuki Kimura, Eisuke Hori, Hideki Kimura, Kenji Kikuchi, Yuji Suzuki
