Patent number: 10315775Abstract: An aircraft duct structure includes a first duct through which exhaust air from a front-side equipment compartment flows, and a second duct through which exhaust air from a rear-side equipment compartment flows. The first duct has a terminal end part where the exhaust air inside the second duct flows into the exhaust air inside the first duct at a substantially right angle, and a flow straightening plate located inside the terminal end part. The terminal end part has a jet opening which faces, across a clearance, an air pressure regulating port where an air pressure regulating valve is disposed. The inside of the terminal end part is divided by the flow straightening plate into an upper region and a lower region. The exhaust air inside the first duct and the exhaust air inside the second duct merge together in the upper region.Type: GrantFiled: February 24, 2016Date of Patent: June 11, 2019Assignee: MITSUBISHI AIRCRAFT CORPORATIONInventors: Masatoshi Morishita, Yoichi Uefuji, Toshiyuki Ishida, Gento Ichikawa, Yasunari Tanaka, Fumio Kondo

Patent number: 5929880Abstract: A powder particle lumping recording apparatus low in cost and high in printing quality is disclosed. Toner 12 having a magnetic property contained in a toner container 21 is conveyed by a developing roller 11 constituting a magnet roller, and jumped under the effect of the electric field controlled by a control electrode formed on an FPC 22. The toner 12 is accelerated by the acceleration voltage for the conductive roller 15, attaches on a recording material inserted between the control electrode 13 and the conductive roller 15, and thus forms an image. The conductive roller 15 contains a magnet 16 therein. With the approach of the magnet 16 to the control electrode 13 by rotation of the conductive roller 15, the toner 12 can be attracted off. The toner 12 attached on the surface of the conductive roller 15 is mechanically removed by a cleaning blade 17 and accumulated in a housing 18. The conductive roller 15, the cleaning blade 17 and the housing 18 make up an easily-demountable cleaning unit 19.Type: GrantFiled: March 21, 1997Date of Patent: July 27, 1999Assignees: Ito Communication Ltd, Ito IncorporatedInventors: Katsuhiko Gotoda, Hisanobu Inada, Fumio Kondo, Susumu Shoji
