A supplying apparatus supplies a combustible material capable of enhancing the sealing effects of a supplying system for supplying a combustible material, such as combustible wastes, to a fluidized-bed chamber, stably supplies a combustible material having an undefined shape, and reduces cost for installation. The device includes a first T-shaped structure defined via a first leg and a first platform. The efficiency of such a system is greatly enhanced by illuminating the target with a polarized light source, and PDI-enhanced targets can be constructed with surface features and textures optimised to result in a maximum return signal strength and spatial contrast. The fruit is uniformly large in size, mildly acidic and sweet in flavor, globose in shape, clingstone in type, very firm in texture, yellow in flesh color, and full dark red in skin color. The apparatus then performs screen processing on the image data including the edge that has undergone the density correction, and performs smoothing processing on the edge in screen data obtained through the screen processing. The layer or layers of densified dielectric material formed from the low k dielectric material provide mechanical support and can then function as etch stop and mask layers for the formation of vias andor trenches.
