In trapping process of a multicolor image, an adjacent vector between an objective figure and a relative figure at an upper side is specified first. The aligning implement comprises a substrate having a plurality of ridges formed on one surface thereof with the predetermined pitch and aligned substantially in parallel with one another, and a cover member having a plurality of ridges formed on one surface thereof with the predetermined pitch and aligned substantially in parallel with one another. A key feature of the invention’s process is a mole ratio of gas additive to source of silicon, which is maintained in the range of about 0. Top connector of top frame is removably secured to an overhead support while bottom frame is spaced from stage or other surface. A control and display unit with a plurality of input mechanisms receives inputs from a user who selects a desired cutting rate or frequency for the cutter. The method also connects the volatile memory directly to an expansion bus of the host computer system, such as a PCI bus.
