  • Patent number: 6681046
    Abstract: Work of defining a ledger slip for an OCR is reduced as much as possible in registering the kind and position of characters and symbols inputted in the slip. Image data is analyzed to detect a cell (frame in which characters and symbols are entered) included in the image data. It is determined whether the cells continue in a constant pattern. If the cells continue, it is determined that the continuous cells area group of cells in which a common attribute is to be registered. The cell group for which a common attribute is to be registered is displayed on a display device distinctively from other cell groups. The operator can perform a modification work on a specific cell group on the display screen, such as elimination and addition of a part of cells. The operator can also specify a cell group and input an attribute to all cells included in that cell group in a bundle.

  • Patent number: 5792883
    Abstract: An improved process for preparing a diaryl carbonate from a diaryl oxalate in a liquid phase by decarbonylation utilizes a reaction vessel composed of two or more reaction chambers which are connected in series. The process is composed of the steps of continuously introducing the diaryl oxalate and an organic phosphorus compound having a trivalent or pentavalent phosphorus atom and at least one carbon-phosphorus bonding into the first chamber and continuously recovering a reaction mixture mainly containing the diaryl carbonate from the last chamber under the condition that a mixture of the diaryl oxalate and the organic phosphorus compound is heated in the reaction chambers, while discharging carbon monoxide released from the mixture.
