  • Patent number: 5819280
    Abstract: A structure of hierarchically structured data including two or more data pieces having a hierarchical relationship is determined. An identifier is added to a data piece that is an element of the hierarchically structured data. The method determines whether or not there are two or more data pieces with the same identifier as the identifier of a first data piece, in a hierarchical data sequence composed of the first data piece and a second data piece placed below the first data piece, determines that an infinite hierarchical structure takes place when there are two or more data pieces with the same identifier if the second data piece is placed below the first data piece, and determines that an infinite hierarchical structure does not take place when there are not two or more data pieces with the same identifier, even if the second data piece is placed below the first data piece.

  • Patent number: 5734450
    Abstract: Common lines are formed in parallel with gate lines. A line which joins those parallel lines is provided in parallel with source lines on the substrate edge part on the gate line terminals side. Another line which joins the same parallel lines is provided in parallel with source lines on the substrate edge part on the opposite side of the gate line terminals. These two terminals are supplied with a signal which is identical with the common signal being applied to an opposing electrode. Depressed portions are provided for each pixel electrode at positions where the source line and common line intersect with each other or in the vicinity of the source line on both sides thereof.
