Abstract: In a simulation considering a skin effect, a signal conductor is vertically and horizontally divided by faces parallel to the surface of the signal conductor, which are set so that intervals are smaller as the faces are nearer to the surface, and larger as the faces are farther from the surface. Also a ground conductor is vertically divided with a similar method, and an integration calculation is made, so that the resistance of the signal conductor, which corresponds to a given frequency, is obtained.

Abstract: A low irritant, mild detergent composition is disclosed. The detergent composition comprises, as essential components, (a) alkyl glycoside, (b) a surface active agent containing sulfate and/or sulfonate group, (c) an amine oxide, and (d) an ethoxylated surface active agent at a specific ratio. The detergent composition is low irritant, has excellent foaming ability and detergency, and yet is easily rinsed out and at the same time provides a pleasant feeling to the hands during use. It can be used as laundry detergents, dishwashing detergents, as well as detergents for use with household products, and hair and body. Further, a detergent composition comprising (e) a terpene type hydrocarbon and (f) 3-isothiazolone or its derivative in addition to the above components (a)-(d) is more valuable in practical use owing to preventing solution color and odor from being deteriorated during storage for a prolonged period of time.
