Abstract: In a fuzzy control apparatus in which a rule is capable of being changed during operation, a fuzzy reasoning output which prevails immediately prior to a rule change is stored when a rule change is made, and a fuzzy-control output is generated by combining, after the rule change, the stored fuzzy reasoning output which prevailed immediately prior to the rule change and a fuzzy reasoning output which prevails following the rule change. The ratio of the combination is altered in such a manner that, with the passage of time from the moment at which the rule change is made, there is a gradual decrease in a percentage of the fuzzy reasoning output which prevailed immediately prior to the rule change, and a gradual increase in a percentage of the fuzzy reasoning output which prevails following the rule change, in the fuzzy-control output. Upon passage of a predetermined time from the moment at which the rule change is made, the fuzzy reasoning output which prevails following the rule change is outputted as the fuzzy-control output. As a result, a sudden change in the output at the time of a rule change is prevented so that a smooth changeover can be carried out. <MATH>

Title: Method of electrolytically coating a steel strip with a metal layer at least partly of zinc

Abstract: A steel strip (1) is electrolytically coated with a metal layer at least partly of zinc in an electrochemical cell having an insoluble anode (4), wherein the strip acts as cathode. The electrolyte in the cell contains chloride ions and has high conductivity, reducing the voltage required. To avoid production of chlorine gas, hydrogen in the form of a hydrogen gas or gas containing hydrogen is supplied to the anode (4). The anode (4) is selected so that the anode reaction:    H2 -> 2H<+> + 2e<->   (V> takes place, this reaction (V) predominating at the anode over the reaction:    2Cl<-> -> Cl2  &uarr&  + 2e<->   (IV). <IMAGE>
