A graphics pipeline system is provided for graphics processing. Such system includes a transform module adapted for being coupled to a vertex attribute buffer for receiving vertex data. The transform module serves to transform the vertex data from object space to screen space. Coupled to the transform module is a lighting module which is positioned on the single semiconductor platform for performi...

A porous bronze 1b and a resin 1c impregnated in pores of the porous bronze 1b formed on a backing metal 1a constitute a bearing 1. At a surface to be brought into contact with a crank shaft 5, porous bronze 1b and resin 1c are sparsely exposed. Ratio of area of exposure of porous bronze 1b at the contact surface 1d is at least 5% and at most 60%. Thus a bearing for a refrigerating compressor havi...
