Also, in the method, input circuits 82a-82n whereby a higher-harmonic input for an inspection is inputted being superimposed on the electric quantity of the power system and an amplitude controlling circuit 12 which controls the amplitude value of the higher-harmonic input for the inspection are provided respectively. Further, the higher-harmonic input for the inspection is superimposed on the electric quantity of the power system while its amplitude value is increased gradually during an enough long time compared with the response time of the filter. When the input for the inspection is applied to the operation of the relay in this manner, the transient output caused by the change of the input for the inspection is very small, and therefore, the input for the inspection can be applied to the relay with a slight effect on the protective operation of the relay.

Filed: 1995-12-12
Abstract: PURPOSE: To rapidly enhance the light emitting output by sandwiching an active layer made of InGaN between n type clad layers made of InGaN having a larger band gap than that of this active layer. CONSTITUTION: An active layer 6 is formed between the first n type and p type clad layers 5 and 7. This active layer 6 formed of InxGa1-x N (0<x<1) may be either n type or p type and can emit light between bands by being undoped and enables half value width of the emitted wavelength to be narrowed. As for a preferable combination of the active layer 6 and the first n type and p type clad layers 5 and 7, the first n type clad layer 5, the active layer 6 and the first p type clad layer may be formed of respectively Iny Ga1-y N, Inx Ga1-x N and Inz Ga1-z N. In terms of the relation of the band gaps, it is mandatory to be y<x, z<x. Through these procedures, the crystallizability of the active layer 6 can be enhanced to notably improve the luminous output, thereby enabling a high brightness green colored LED although conventionally hard to make to be realized.

Abstract: PROBLEM TO BE SOLVED: To improve plating adhesion and to obtain excellent corrosion resistance, formability, weldability, etc., by applying electroplating to a metal sheet by the use of an electrogalvanizing bath containing a Co supply source and dextrin, melting specific amount of plating film of initial plating, and then continuing plating. SOLUTION: A cold rolled steel sheet is electroplated in an electrogalvanizing bath containing a Co supply source and dextrin or dextran of >=10 number- average molecular weight, by which a composite zinc alloy plating film, containing 0.01-10 wt.% high molecular weight organic matter consisting of C, O, and H and 0.01-10% Co, is formed at least on one side of the steel sheet at 5 to 100 g/m<2> coating weight. At the time of this electroplating, electrification is temporarily stopped after initial plating and the resultant plating film is naturally melted by the amount of (0.05 to 0.5) g/m<2> , by which Co-enriched micro-ruggedness is formed at the surface. After that, plating is further continued until prescribed coating weight is reached. By this method, the composite zinc alloy plated steel sheet excellent in plating adhesion can be obtained.
