A frame of a metal-forming press having upper and lower traverses interconnected by vertical columns having upper and lower ends is provided with respective sets each of a plurality of identical tension bolts at each end of each of the columns. The generating unit generates a plurality of histograms of images with respect to each color based on an input image. A diamond polycrystalline body having high heat resistance and mechanical strength and having conductivity enabling electrical discharge machining is obtained by using only an amorphous or fine graphite-type carbon material as a starting material, adding boron thereto and concurrently performing conversion into diamond and sintering in an ultra-high pressure and temperature condition. Further, the user is encouraged to purchase a license for another software product having a tint block printing function. The elements of the manipulator device cooperate to constrain the end effector to rotate about a remote center of motion that is displaced from a proximal center of motion as the drive link moves a carriage of the second linear slide along an arcuate path.
