Abstract: A domain covering a drawing data subjected to information processing is determined and equally divided into meshes of predetermined smallest size. For each of vectors constituting a drawing data subjected to the processing, the number of the meshes traversed by the vector is counted. When the number of the meshes traversed by a given one of the vectors exceeds a predetermined value, the domain is equally divided into meshes of a larger mesh size and the number of the updated meshes traversed by the given one vector is counted. By repeating this operation, all the vectors are stored in a memory as the drawing information in terms of the mesh size and the coordinates of the meshes traversed by vector. Since the number of the meshes traversed by the vector thus can not exceed the predetermined value, the speeding-up of the drawing information processing can be accomplished. A predetermined value may be provided for the mesh size, if desired.

Abstract: Herein disclosed is a process of fabricating a semiconductor integrated circuit device, in which there is formed between a conductive layer prepared by covering a polycrystalline silicon layer with either a layer containing a refractory metal of high melting point, i.e., a refractory metal layer or a silicide layer of the refractory metal and a first insulating film made of phosphosilicate glass flowing over said conductive layer containing the refractory metal, a second insulating film preventing the layer containing a refractory metal from peeling from the polycrystalline silicon layer by the glass flow. The second insulating film is formed by deposition to have a thickness not smaller than a predetermined value.

Abstract: A semiconductor memory includes a word line driving circuit whose output terminal is coupled to one end of each word line of a memory array, and also an auxiliary driving circuit which drives the other end of the word line upon receiving a selection signal transmitted to the other end of this word line. The auxiliary driving circuit comprises a level detector circuit which is dynamically driven by a timing signal, and a driving element which is driven by an output of the level detector circuit to drive the other end of the word line. When the word line is to be reset, the output of the level detector circuit is set at a level which brings the driving element into an "off" state. The auxiliary driving circuit of this arrangement permits the other end of the word line to change to a selection level quickly and to be reset quickly.

Abstract: A line recognition adapted for recognizing a drawing in which a plurality of lines overlapping one another are indicated by a given one of the mutually overlapping lines and overlap symbols representative of the other lines. The overlap symbols are so configured as to give information as to line kinds of the other lines such as solid line, dash line and chain line and/or information as to colors of the other lines. The paths of the other lines are estimated on the basis of the overlap symbols as well as the positions at which they are inserted, for thereby recognizing the whole line paths or patterns of the drawing.
