  • Patent number: 7973960
    Abstract: A document processing system is disclosed that is capable of processing both fixed-format and unfixed-format hand written paper documents. The document processing system includes an encoding unit that encodes a sheet ID for identifying a hand written first document on a sheet to generate a coded sheet ID; a decoding unit that decodes the coded sheet ID; a document-sheet ID association unit that associates the sheet ID with a document ID assigned to a computerized second document; a printing unit that acquires the sheet ID and prints the coded sheet ID on the first document; a sheet ID management unit that manages the sheet ID; an information acquisition unit that acquires the sheet ID decoded by the decoding unit, and hand-written data from the first document on which the coded sheet ID is printed; and a process-sheet ID association unit that associates the sheet ID with a process ID of a process for processing the hand-written data acquired by the information acquisition unit.

  • Publication number: 20100252111
    Abstract: Provided are a paste composition capable of achieving a BSF effect which is equivalent to or greater than a conventionally achieved BSF effect even when used in either case where a thin back surface electrode layer is formed on a thick silicon semiconductor substrate or case where a thin back surface electrode layer is formed on a thin silicon semiconductor substrate and, when used in a case where a thin back surface electrode layer is formed on a thin silicon semiconductor substrate, not only capable of achieving a BSF effect which is equivalent to or greater than a conventionally achieved BSF effect, but also capable of more suppressing deformation of the silicon semiconductor substrate after being fired, than in a case where the conventional paste composition is used in order to form a thin back surface electrode layer; and a solar cell element comprising an electrode formed by using the paste composition.

  • Publication number: 20070216703
    Abstract: A rotating unit forwards and rewinds a recording medium by rotating in a normal direction and in a reverse direction, respectively. A recording unit records an image on a surface of the recording medium. An erasing unit erases the image recorded on the surface of the recording medium. A shift-amount adjusting unit adjusts a shift amount per unit time of a forwarding portion of the recording medium at a recording position or on an upstream side of the recording position in a forwarding direction. A weight is fixed to the forwarding portion of the recording medium exposed outside from an opening that is provided on a casing.

  • Patent number: 5815205
    Abstract: An electronic camera which detachably connects to a communication interface which allows the camera to communicate with an electronic device such as a personal computer. The communication interface includes circuitry which converts signals utilized by a microprocessor within the camera which are usually within a range of 0 to +5 volts to a level which is utilized to communicate with the computer. When an RS-232 connection is used to communicate between the camera and the computer, the circuitry within the communication interface converts the signals utilized by the camera to a level between -15 and -5 volts for a low signal and +5 and +15 volts for a high signal. The communication interface includes a mechanical connector having two latching mechanisms which connect to receiving members of the camera. The latching mechanisms pivot and are both moved by a single pushing member.
