An upper side for a multiple-layer sheet-forming fabric has a multiplicity of longitudinal threads woven with a multiplicity of transverse threads and thereby form repeats in the longitudinal and transverse directions. The unit or projector uses, as a polarizeranalyzer for a reflection liquid crystal panel, a reflection polarizing plate which functions as a polarizing plate by its grating function only in a specific direction. Some of them are disposed close to an outer convex surface of the hot water sprayer head and some extending close to a central axis of the hot water sprayer head. The LED package improves the light efficiency by arranging the plurality of LED chips so as to correspond to a shape of effective light having an asymmetric distribution with respect to a stop of a projection lens unit. A system may be formed by integrating the semiconductor devices with one or more memory semiconductor arrays or conventional logic devices, such as a complementary metal-oxide-semiconductor device.
