A control system enables a considerable decrease in electric power consumption of backup power, leading to effective prevention of a dead battery, while data in each control unit which need be maintained even after power is turned off is properly maintained. Included are in situ cleaning and conditioning of the substrate, and the application of an adhesion layer between the substrate and the patterned layer, as well as forming an intermediate layer between adhesion materials and the substrate. A contact assembly is spaced from the anode within the reactor bowl. Setting means adjust the loci defined by the locus generating means.
