Abstract: Provided is a method of manufacturing a grain-refined aluminum-zinc-magnesium-copper alloy sheet, including manufacturing an aluminum alloy sheet from an aluminum-zinc-magnesium-copper alloy melt by twin-roll strip casting, primarily rolling the aluminum alloy sheet manufactured in step 1, cold rolling the aluminum alloy sheet manufactured in step 2, and performing a heat treatment on the aluminum alloy sheet manufactured in step 3, thereby reducing processing time and cost by using twin-roll casting. Since grain refinement and homogenization of the sheet manufactured by the twin-roll casting are maximized by sequentially performing warm rolling, cold rolling, and a heat treatment on the sheet, elongation may be improved.

Abstract: In an apparatus for precisely locating an orthodontic bracket at a predetermined position on a surface of a tooth, orthodontic brackets for holding orthodontic wires can be easily and precisely located at and adhered to a predetermined position on a surface of a tooth, not only at an initial time but also even when the used orthodontic brackets are separated from the surface of the tooth in the course of the orthodontic treatment. The apparatus has a suspension body, a ring, and a molding spacer. The suspension body is disposed extending in parallel with the tooth from an apex toward a dental root of the tooth with a predetermined gap. The ring is inserted in the groove and hooked around the hook after the holding member has been fittedly inserted in the fitting recess, to thereby tightly assemble the suspension body and the orthodontic bracket together. The molding spacer is disposed between the suspension body and the tooth.
