  • Publication number: 20040005471
    Abstract: A clear coated metal sheet has a clear-paint film 1, which disperses an interference-coloring pigment 4 therein, formed on a base metal sheet 3 directly or through an under clear coat 6. The pigment 4 comprises transparent or translucent inorganic flakes, e.g. mica, glass, alumina or silica, coated with one or more metal oxide layers, e.g. TiO2, SiO2, ZrO2, Fe2O3, SnO2, Fe3O4, Cr2O3, ZnO or Al2O3. Incident light Lin, which enters in the clear-paint film 1, is reflected on the pigment 4 and a surface of the base metal sheet 3. A colored surface with metallic luster is observed due to interference of light on the pigment 4. Since a color tone is stable without thickness effect of the clear-paint film 1, the clear sheet is useful as decorative members.

  • Patent number: 4783648
    Abstract: In a multiwindow system in which a plurality of windows are set on a display screen at positions such that these windows partially overlap and the display priority and position of each window can be arbitrarily changed, when the operator instructs to change the display priority of the window, a check is automatically made to see if there exists the window which will be completely covered by the other windows having priorities higher than that of this window and will fully disappear from the screen if the display priority is changed or not. If such a window is found out, the display priority of this window is changed in the state in which this window is automatically shifted to the position where a part of this window can be seen on the screen, thereafter the window is displayed on the screen.
