Abstract: The present invention published a method of mechanically operated scouring abrasion and a mechanically operated scouring abrasion head which transmits the pushing force to the top of the scouring abrasion object to scour and abrade the surface. The mechanically operated scouring abrasion head comprises a scouring abrasion object, scouring abrasion head, supporting position and pushing position. The scouring abrasion object is connected with the scouring abrasion head. The supporting position is on the scouring abrasion head wherein a ratio of the scouring and abrasion force is adjusted by adjusting a position and work pattern of the supporting position to generate scouring and abrasion momentum of different ratios and swing the scouring abrasion object back and forth downward. The present invention deals with the stains in the irregular concaves, which rapidly clean the convex or the stubborn stains on the regular plane which can't be achieved by the conventional technology.

Abstract: A single pixel monochromatic display and signal-receivable module, and a device containing the module; the module is mainly a combination of a set of lenses and a color mixing screen; light beams projected from color light sources are converged through a light convergent plate, and then refracted through the light refractive color convergent plate which has refraction curved surfaces to same locations on a color mixing screen on which a single color is formed and a single pixel is thereby constituted; even subject to enlargement, there are no more tri-colors in a single pixel but only one single color in a single pixel; the module can also be used to emit or receive invisible electromagnetic waves, or can receive electromagnetic wave signals of another wave length during display.
