    摘要: Electrostatic latent images are developed by closely positioning a developer carrying member having on a surface a developer composed of fine particles containing an organic semiconductor and being insulating at a normal state adjacent to an electrostatic latent image bearing surface in such a manner that the surface provided with the developer of the developer carrying member facaes the electrostatic latent image bearing surface, and thereby electric charges which are opposite in polarity to the electric charges of the electrostatic latent images being injected into the developer from the developer carrying member by an electric field formed between the electrostatic latent image bearing surface and the developer carrying member and the electrostatic latent images being developed by the developer.

    摘要: The present invention relates to a high elongation, high strength pitch-type carbon fiber which has an improved handleability. The carbon fiber of this invention has a crystalline structure arranged in such a manner that the angle (.phi.) is 24.degree.-38.degree.; the stack height (L.sub.c) is 19-35 .ANG.; and, the interlayer spacing (d.sub.002) of the X-ray structural parameter is 3.45-3.50 .ANG.. The atomic ratio of oxygen to carbon on the surface of the fiber measured by X-ray photoelectron spectrometry is 0.1-0.35. The total oxygen content in the fiber is 0.01-0.2 wt. %; and, the elongation is 1.0% or more. The high elongation, high strength pitch-type carbon fiber prepared in accordance with the present invention can be used, for example, as a reinforcing fiber for light-weight structural material employed in the aerospace, automotive and architectural industries.

    摘要: A method is provided for the orthocorrection of a satellite-acquired image. This method can be applied even if ground control points are not set. Without propagation of an error throughout the image and also without needing an excessively large amount of calculations, the method makes it possible to correct ground-relief-associated distortions caused by the relief of a ground surface. According to the method, a plurality of control planes of different elevations are set relative to a control plane of a zero elevation of a reference rotating ellipsoidal earth model. A corrected image is divided into blocks by lattices of equal intervals. With respect to each of these blocks, distortion model formulas in the form of bilinear functions are determined for the respective control planes. Concerning each pixel position in the corrected image, two pixel positions in an observed image, which correspond to the elevation value of the pixel position in the block, are calculated by using distortion model formulas for two control planes which directly sandwich the value of elevation above and below the value in the corresponding block. By the value of elevation, the two pixel positions are linearly interpolated to determine the desired pixel position in the observed image.
