Abstract: A razor blade is provided. The razor blade includes a substrate including a substrate tip, and a first surface and a second surface extending from the substrate tip; and a coating, layered on the substrate, including an ultimate tip, and a first cutting surface and a second cutting surface extending from the ultimate tip and corresponding to the first surface and the second surface, respectively, wherein the first cutting surface includes a first facet extending from the ultimate tip and a second facet extending from the first facet, the second cutting surface includes a third facet extending from the ultimate tip and corresponding to the first facet and the second facet, a first line tangent to the first facet and a second line tangent to the second facet are not parallel, and the ultimate tip is deviated from a central line that divides the substrate in two and passes through the substrate tip.

Abstract: A method of manufacturing a non-molded solid fuel using a combustible waste material includes (a) primarily crushing an inflowing waste material using a bag-tearing and crushing device, (b) separating iron from the primarily crushed waste material using a first magnetic sorter, (c) sorting the waste material, from which the iron is separated, according to the particle size of the waste material using a first oscillating multi-stage particle-size sorter, (d) secondarily crushing the waste material having a large particle size using an impact crusher, (e) separating the iron from the secondarily crushed waste material using a second magnetic sorter, (f) sorting the waste material, from which the iron is separated, according to the weight of the waste material using a wind power sorter, (g) separating the iron from a light material, and (h) pulverizing the waste material, from which the iron is separated.

Abstract: Disclosed is a three-dimensional radiation detection and visualization system. The three-dimensional radiation detection and visualization system includes a first sensing module including one radiation sensor, a second sensing module including one image sensor, a first supporting body in which the first sensing module and the second sensing module are coupled to one side and the other side thereof to be vertically rotated, and a second supporting body coupled with the first supporting body so that the first supporting body is vertically rotated.
