A CPU includes a bus interface, a control unit, an instruction cache, a data cache, a secondary cache, an instruction decoder, an arithmetic unit, and registers. The inner flexible tube is disposed in the outer flexible tube so that a distal end thereof is positioned between the distal ends of the core shaft and the stranded wire and a proximal end of the core shaft so as to be separated from the distal ends of the core shaft and the stranded wire. The pattern selector reads a predetermined library of equivalent pattern sets and selects an equivalent pattern set for the declared pattern. The metal supplying the N well voltage is formed using a metal in the first metal interconnection layer and thus does not require a piling region to the underlayer, and only a piling region to the underlayer of the metal for the P well voltage needs to be secured. The system further includes a media volume production facility remotely located from the digital image terminal, and communicatively coupled to the digital image terminal via a server-operated computer network.
