Abstract: A high power MOSFET semiconductor having a high breakdown voltage. The new power device concept that reaches an area of a lower specific on-resistance, higher breakdown voltage and reduced device silicon area. This device architecture is built on the concepts of charge compensation in the drift region of the device. Where, the doping of the vertical drift region is increased by one order of magnitude. To counterbalance the added charges, fine-structured wells of opposite doping type to the drift region are introduced as part of the device structure. The charge compensation wells do not contribute to the on-state current conduction, therefore, this novel new generation of high voltage device architecture breaks the limit line of silicon. This architecture may extend to higher material resistivity and larger geometry to increase the voltage to 1kv plus.

Abstract: In a xerographic printer including a fuser having a heating element, a first predetermined power level is applied to the heating element. The voltage associated with the element is measured, yielding a code which is applied to a look-up table. The output of the look-up table relates to power to be applied to the element in a time interval T going forward: the output sets forth what power level is to be applied to the element for a smaller interval t within interval T, and what power level is to be applied to the element for the balance of the interval T.

Abstract: In a copier or input scanner wherein original documents are manually placed on a platen for scanning, when a platen cover is lowered over the document and approaches a closed position, a control system initiates a scanning operation while locking the platen cover in the closed position. After the scanning operation is completed, the platen cover is automatically pushed into an open position as a visual cue to the user that a new document may be scanned. The system facilitates manual scanning of odd-shaped documents, such as successive pages of bound books.

Abstract: A double-sided printing apparatus includes: a first printing control unit which receives printing data including page-number information per slip so as to print a slip on the obverse of a sheet by selecting printing data for printing on the obverse; and a second printing control unit which receives size information of the slip to be printed on the obverse as well as printing data for printing on the reverse of the sheet. The second printing control reads a mark printed on the obverse by using a mark reading sensor at a timing according to the size information, and compares page-number information obtained by reading the mark with that included in the printing data for printing on the reverse, so as to print, on the reverse of one page of the sheet, a slip having the page-number following that of the slip printed on the obverse of the same page.

Abstract: The present invention relates to a methodology for assembling a document from content spanning multiple web-pages. Given a starting location, one process analyzes a single page at a time to find candidate links. The links are recursively followed and those pages are analyzed. A detailed set of heuristics is used to determine what is or is not a candidate link. The candidate pages are then optionally fed to a document-level analyzer. This process compares the attributes of one page against the others and looks for a document-like structure. Using another detailed set of heuristics, the document-level analyzer determines if the page should be included in the document.

Abstract: Disclosed is a process for forming a channel wafer for a novel ink jet printhead, having an ink particle-filter layer over the ink-inlet surface thereof. The process comprises the steps of applying a thin coating of a heat-curable, photopatternable polymer composition to an intermediate substrate having a release surface and drying the coating to form a semi-solid adhesive layer. The layer and supporting substrate are pressed against the ink-inlet surface of a channel wafer with an optional adhesive layer to bond the layer to the ink inlet surface. The substrate is separated to transfer the contacting area of the semi-solid layer to the ink-inlet surface as a laminate, and the semi-solid layer is exposed through a filter-forming mask and ink particle-filter openings are developed therethrough, either before or after transfer of the semi-solid adhesive layer from the intermediate substrate to the ink-inlet surface of the channel wafer, and the filter layer is cured.
