A semiconductor package is provided that includes an electrical connection and support means having a front face and a recess in the front face. Allowed correction ranges for chroma, brightness and hue angle based on a color difference formula are set to the selectable ranges. The foldable portions can fit into the pockets and then be folded so as to generate tension in the retention member. Each domain is allocated one or more processor resources. In addition, a part of the light is reflected by the second reflective plate, is incident on the diffusion plate bonded to the third reflective plate, is efficiently diffused by the diffusion plate, and uniformly illuminates an operation unit such as a keyboard. The method involves coordinating the operation of at least two mining conveyors to facilitate mining at least one arc-shaped sector of ore that otherwise would not be within operational reach of the slurry facility at the ore processing location.
