摘要： PURPOSE:To present the graphic operation processing system shortening time for processing with comparatively simple constitution. CONSTITUTION:The area of a main memory at a computer system is secured and corresponding to the plural kinds of intermediate data generated in a graphic arithmetic operation processing to be started from now, plural storage areas to respectively store the data are allocated. Then, the graphic arithmetic operation processing is executed by using the storage area allocated the intermediate data generated by an input graphic data based on the input graphic data stored on a disk file. The graphic arithmetic operation processing is executed while dynamically securing the areas and storing the intermediate data, which are generated in the graphic arithmetic operation processing, required for the processing onto the main memory. Thus, since the limited storage capacity of the main memory can be efficiently utilized and the intermediate data can be processed while being replaced onto the main memory, time for the graphic arithmetic operation processing can be shortened.

摘要： PURPOSE:To continuously operate the working without adjusting before working or preparation-shifting on the way of working by working the flange while making the forming tool to rotate and to turn inclined. CONSTITUTION:The driving means 7 gives the forming tool 6 a rotation around the main shaft 4 and a inclined turn around a pivot joint end part, also by giving a thrust force in the main shaft axial direction, the forming tool rotates while revoluting by contact with the end part of the metallic tube 30, and turns inclined while pushing and opening the end part in flare state. With the revolution, the rotation and the inclined turn of this forming tool 6, the flange 32 is formed at the end part of metallic tube 32. That is, the flange 32 is worked with the continuous working operation without adjusting before working or preparation shifting on the way of working. Therefore, the working man-hour is reduced largely and also the line up for the piping equipment line is made easy.

摘要： PURPOSE:To improve processing capacity by moving a series of vectors in parallel by a designated enlargement or reduction width and erasing a pair of vectors which are mutually adjacent, which are at a moving angle smaller than 180 deg. in front of a moving direction and which have an intersected point after movement. CONSTITUTION:An input graphic having eight apexes A-H is expressed by eight vectors connected clockwise, for example. A series of the vectors are moved in parallel by the designated enlargement or reduction width. Then, a pair of the vectors which are mutually adjacent, which are at the angle smaller than 180 deg. in front of the moving direction and which have the intersected point after movement are erased at the back of the moving direction. Thus, a processing is attained for the input graphic having sides of arbittray angles without the occurrence of an unjust graphic.
