Patent number: 7544993Abstract: A semiconductor storage device has memory function bodies (261, 262) having a function to retain electric charges, which are formed on opposite sides of a single gate electrode (217) provided on a semiconductor layer (211) with a gate insulation film (214) disposed therebetween. Each memory function body includes a charge retention film (242) having a charge storage region (250). The charge storage regions (250) exist over part of the channel region (273) and part of diffusion regions (212, 213) on both sides of the channel region. Because the memory function bodies are formed on both sides of the gate electrode, independently of the gate insulation film, 2-bit operations are possible. Because the memory function bodies are separated from each other by the gate electrode, interference during rewrite operation is effectively suppressed. Also, short-channel effect is suppressed through thinning of the gate insulation film. Miniaturization of memory elements is thus facilitated.Type: GrantFiled: December 19, 2003Date of Patent: June 9, 2009Assignee: Sharp Kabushiki KaishaInventors: Hiroshi Iwata, Akihide Shibata

Publication number: 20090142091Abstract: An image forming apparatus performs a single-side image formation in a way that, when delay of image formation is needed to secure time for post-process, a stacked sheet discharge control section controls a sheet carrying mechanism so that: a first sheet (for a second imaging job) to be discharged after passing a first sheet-discharging roller via a first sheet-carrying path is directed to another carrying path without being discharged, and is stood by therein; and the first sheet and a second sheet (for the second imaging job) which is carried to the first sheet-discharging roller via the first sheet-carrying path subsequently after the first sheet, are concurrently discharged overlappedly. For imaging jobs in succession, this eliminates needs for delaying image formation for the second imaging job, and for securing time for post-process for the first imaging job. Even the delay is inevitable, this reduces the delay time greatly.Type: ApplicationFiled: December 3, 2008Publication date: June 4, 2009Applicant: Sharp Kabushiki KaishaInventor: Kenji Tanaka

Publication number: 20090141951Abstract: When a user operates a processing apparatus through a touch panel, a fingerprint processing unit reads fingerprint information of the user's finger. Each time when the fingerprint processing unit reads fingerprint information, a CPU judges whether the read fingerprint information is identical to a fingerprint information of authenticated user. If being identical, the processing apparatus executes a process in accordance with an operation accepted through the touch panel. These two fingerprint information are identical each other if the operating user through the operation accepting panel is the authenticated user. It means that the processing apparatus judges whether the operating user is the authenticated user, each time when the user operates. If the user is the authenticated user, the process in accordance with the operation by this user is then executed.Type: ApplicationFiled: October 31, 2008Publication date: June 4, 2009Applicant: SHARP KABUSHIKI KAISHAInventors: Atsushi Ogo, Yuji Okamoto, Shuhji Fujii
