An apparatus for the sealing of roof assemblies for a building structure, wherein the apparatus includes a vertically configured roller and a plurality of horizontally configured rollers to simultaneously produce a hook in the female panel edge and seal the male and female edge together is provided. As a synthesis method, sol including a metal alkoxide andor a metal salt and a functional chelating agent may be prepared and the organic-inorganic hybrid material may be synthesized by sol-gel method. The capacitor plates may be charged to a predefined voltage and may be separated to generate higher voltages on the order of hundreds of kV in the AK gap. In the display panel, a side face of an edge of the transparent resin film has a reverse tapered shape; the alignment film is separated at the side face of the edge; and the transparent resin film and the sealing member are attached to each other without having the alignment film therebetween. This prevents shortage of the information processing resources due to the execution of information processing other than the reception of the designated data, which would otherwise impair the reception of the designated data and the execution of the other information processing.
