A network system and network system setting method including a control apparatus connected to a network and an image processing apparatus connected to the control apparatus so as to access the network, where when setup information for the image processing apparatus is transmitted to another image processing apparatus, setup information for the control apparatus is also transmitted. Thus, placement is performed preferentially from the basic cell corresponding to the frequency-division circuit into which a signal having a higher frequency is inputted, and then wiring connection is performed. Suitable phase transfer agents are delineated. The aluminum bearing layer generally includes 4% to 20% by weight lead or tin, up to 26% by weight silicon and up to 2% by weight of any of the elements magnesium, manganese, nickel, zirconium, zinc, copper, or chromium with the remainder of the bearing layer being aluminum.
