Document Type and Number:
WIPO Patent Application WO/2011/058922
Kind Code:
A1
Abstract:
The standard arrangement for concave/convex sections (20) is such that, among the roughly regular hexagon regions that are regularly arranged on a virtual reference surface, the periphery of one first region (A1) is surrounded by six second regions (A2), wherein said standard arrangement continues regularly in the latitudinal and longitudinal direction of the surface, and the concave/convex sections (20) are shaped with first protruding sections (21) and second protruding sections (22) which protrude in the thickness direction and in the opposite direction from each other for the first region (A1) and the second region (A2), respectively. The first protruding sections (21) have a six-sided pyramid shape or a truncated six-sided pyramid shape, and protrude in one of the directions in the thickness direction, the outer circumference contour of the first region (A1) on the reference surface being the base section. The second protruding sections (22) have a six-sided pyramid shape or a truncated six-sided pyramid shape, and protrude in the other direction in the thickness direction, the outer circumference contour of the second region (A2) on the reference surface being the base section.
