Patent number: 7840999Abstract: An image processing apparatus authorizing the use thereof by carrying out user authentication prevents fraudulent use of the processor and/or a data leak due to a user's forgetting invalidation of authentication or other reason. When a user is authenticated, whether the user is authorized to use a DMFP is determined by comparing the user's input information with the information of an access-authorized person stored in the DMFP. When both information matches, a range of functions available for the user are specified, and the user is authenticated. Subsequently, for example, operation of copy setting is carried out in making setting on the DMFP. When the setting operation is over, whether authentication on the user is invalidated is determined to execute processes of copy setting, etc. In response to a trigger of invalidation of authentication on the user, the processes of copy setting, etc., are started.Type: GrantFiled: December 21, 2006Date of Patent: November 23, 2010Assignee: Sharp Kabushiki KaishaInventor: Kazuya Hamaguchi

Publication number: 20070094189Abstract: A test case table stores created test cases and round-by-round test results for each test case. The operator uses a test case extraction dialogue to set test case thinning factors, and also uses a thinning parameter setting dialogue to set a priority order among logics applied for test case extraction. When a test case extraction process is executed, each test case is assigned a priority level for extraction based on the round-by-round test results for each test case in accordance with the set priority order among the logics. High-priority test cases are extracted based on the set thinning factors.Type: ApplicationFiled: October 3, 2006Publication date: April 26, 2007Inventors: Hiroshi Yamamoto, Kiyotaka Kasubuchi, Kazuya Hamaguchi

Publication number: 20070061425Abstract: When a new theme is proposed and a thread is created, a category applicable to the thread is specified. In a menu, the theme and the category are displayed together. The thread is displayed in a form in accordance with the specified category. By specifying the category in accordance with the proposed theme, it is possible to suppress the divergence of comment details made on the thread in advance and limit the direction of comments. Further, on the thread, it becomes easy to display the contents proper for the nature of the proposed theme and efficiently perform an output display. This allows more efficient decision making and information sharing by using a bulletin board system. With this operation, it is possible to provide a bulletin board system in which the direction of comments can be limited in accordance with the category of the theme, such as discussion or question, and a summary of conclusion based on the comment details and an output in accordance with the theme can be efficiently performed.Type: ApplicationFiled: August 8, 2006Publication date: March 15, 2007Inventors: Hiroshi Yamamoto, Kiyotaka Kasubuchi, Kazuya Hamaguchi

Patent number: 5689762Abstract: A reflected-light amount detecting process is performed for white-standard and halftone-standard originals, respectively. Based on the analysis of resulting images, correct exposure voltages Vcl(WH) and Vcl(HT) are determined. When the thus determined voltage is applied to a copy lamp to turn it on, an AE sensor, receiving the light reflected from a corresponding original of the white-standard and halftone-standard originals, and outputs a corresponding output current Vae(WH) or Vae(HT). These output currents detected are used in combination with the correct exposure voltages Vcl(WH) and Vcl(HT), to calculate control constants for determining a control characteristic.Type: GrantFiled: January 17, 1996Date of Patent: November 18, 1997Assignee: Sharp Kabushiki KaishaInventor: Kazuya Hamaguchi

Patent number: 5478061Abstract: A sheet post-processing apparatus is arranged such that in the non-staple mode, the leading edges of the sheets transported from the transport rollers are directed so as to be sandwiched between the upper and lower discharge rollers by a movable sheet guide in a non-staple mode position and the sheets are discharged onto a stacking tray through the upper and lower discharge rollers. In the staple mode, the leading edges of the sheets is directed to a discharge opening formed between the upper discharge roller and the movable sheet guide by the movable sheet guide in the staple mode position so as to be dropped onto the staple tray. After being processed by the stapler, the sheets are pushed by a pushing member through the discharge opening onto the stacking tray.Type: GrantFiled: July 1, 1994Date of Patent: December 26, 1995Assignee: Sharp Kabushiki KaishaInventors: Susumu Murakami, Toshiya Mikita, Koji Katamoto, Naoya Okamura, Tomonori Ohata, Kazuya Hamaguchi
