Patent number: 8207949Abstract: A highly durable touch panel is provided. A touch panel according to the present invention includes a deformable flexible panel, and a transparent electrode film containing In2O3 as a primary component and containing Ti is exposed to a surface of a lower electrode film of a display device. Since such a transparent electrode film has a high abrasion resistance as compared to a conventional one (such as, an ITO thin film), the transparent electrode film is neither clouded nor cracked even if the lower electrode film is repeatedly pressed. Therefore, the touch panel according to the present invention is highly durable.Type: GrantFiled: September 25, 2009Date of Patent: June 26, 2012Assignee: Ulvac, Inc.Inventors: Hirohisa Takahashi, Satoru Takasawa, Isao Sugiura, Atsushi Ota, Satoru Ishibashi, Haruhiko Yamamoto

Publication number: 20120055788Abstract: A transparent electroconductive film having a low resistivity is provided. In a film-forming method of the present invention, a transparent electroconductive film is formed on a surface of a substrate by sputtering, in a vacuum atmosphere, a target in which ZnO is a main component and Al2O3 and TiO2 are added to ZnO, and then the transparent electroconductive film is annealed by the heating thereof at a temperature of 250° C. or more and 400° C. or less. The resistivity of the obtained transparent electroconductive film is reduced because the film has ZnO as the main component and Al and Ti added therein. The transparent electroconductive film formed by the present invention is suitable as a transparent electrode for the FDP, etc.Type: ApplicationFiled: November 16, 2011Publication date: March 8, 2012Applicant: ULVAC, Inc.Inventors: Hirohisa TAKAHASHI, Sadayuki Ukishima, Atsushi Ota, Noriaki Tani, Satoru Ishibashi

Patent number: 7983602Abstract: A toner cartridge is detachably attached to an image forming apparatus and supplies toner to the image forming apparatus. The locking mechanism is positioned either at a locking position or at a non-locking position. Shortly after the toner cartridge has been attached to the image forming apparatus, the locking mechanism is at a non-locking position. When a user operates a driving member of the toner cartridge after the toner cartridge has been attached to the image forming apparatus, the operating lever engages the locking mechanism to cause the locking mechanism to move to a locking position. When the locking mechanism is at the locking position, the locking mechanism limits the driving member to move relative to the engagement portion, so that the toner cartridge is not allowed to be detached from the image forming apparatus.Type: GrantFiled: February 25, 2010Date of Patent: July 19, 2011Assignee: Oki Data CorporationInventors: Tatsuhiko Shimomura, Atsushi Ota

Patent number: 7949287Abstract: A developer cartridge includes an outer barrel member, an inner barrel member rotatably provided with respect to the outer barrel member, and a regulating member rotatably provided with respect to the inner barrel member. The regulating member includes a first engaging portion and a second engaging portion. The inner barrel member includes a first to-be-engaged portion that engages the first engaging portion and an operating member. The outer barrel member includes a second to-be-engaged portion that engages the second engaging portion. When the first engaging portion and the first to-be-engaged portion engage each other and engagement between the second engaging portion and the second to-be-engaged portion is released, the inner barrel member is rotatable together with the regulating member with respect to the outer barrel member.Type: GrantFiled: June 25, 2009Date of Patent: May 24, 2011Assignee: Oki Data CorporationInventor: Atsushi Ota
