    摘要: An antifouling structure in contact with seawater or at least its surface layer is made up of a beryllium copper alloy having a beryllium content lying in the range of 0.2% by weight to 2.8% by weight. While this antifouling structure is immersed in seawater, a beryllium or copper oxide film is formed on the surface layer of the beryllium copper alloy mother material and beryllium or copper ions are liberated from the exposed surface layer of the beryllium copper alloy mother material into seawater. As years go by, the beryllium or copper oxide film peels away from the beryllium copper alloy mother material. Due to indeterminate repetition of such peeling, the liberation of beryllium or copper ions from the exposed surface layer of the beryllium copper alloy mother material into seawater is sustained.

    摘要: When scarfing the end portion of a plate-like material with irregular deformations or undulations, such as distortions, undulations and warps, the undulations are successively corrected flat and the flattened end portion is scarfed by a rotary cutter to form a highly precise scarfed surface. When the end portion of the plate-like material 3 is scarfed by the rotary cutter 5, the pressing member 11 presses, while the cutting operation proceeds, at least a part of the surface of at least that portion of the plate-like material 3 which is to be cut away as a chip 17 at a position near the blades 5b of the rotary cutter 5 on a downstream side of the rotary cutter with respect to a rotary cutter movement direction, the surface of the plate-like material 3 pressed by the pressing member 11 being opposite the other surface held in contact with the cutter receiving table 7.
