Some of the electrons and holes, which are generated in the region 6, the well 6 and the layer 18, are recombined and annihilated and the remnant is turned into a current which is made to flow through a photodiode. The holes among the electrons and holes, which are generated in the substrate 19, are recombined and annihilated or flow out to external terminals, while some of the electrons are recombined and annihilated, some of the electrons pass through the layer 18 and the well 6 to flow out to a DC voltage terminal and the remnant is diffused in the layer 20 through the substrate 19 and are recombined and annihilated. Thereby, a high quality image, in which smears are restrained, is obtained.

Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a pavement material for a draining elastic pavement, having high adhesive force to a roadbed and excellent in performance for draining water impregnated in the material in raining. SOLUTION: Drain grooves 11 each of which has the semicircular section are provided on a contact surface 10b side to a roadbed 13, in a pavement material 10.
