Abstract: A radiated electromagnetic wave estimation is performed by a computer. The estimation process includes: converting a circuit diagram of an electronic circuit board into a combination of a plurality of partial circuits; and predicting radiated electromagnetic waves from the electronic circuit board by using a prediction result of a radiated electromagnetic wave for each of the partial circuits obtained by the converting.

Abstract: Disclosed is a fiber-treating agent composition comprising an oil-in-water emulsion wherein composition (A) comprising the following component (b) is emulsified with the following component (a): a polymer compound of a polysaccharide derivative, and component (b): a polyether-modified silicone having an HLB value of larger than zero to 7 or smaller; wherein the mass ratio of the component (a) to the component (b) in the composition, that is, the component (a)/component (b), is 9/100 to 30/100.

Abstract: Disclosed is a fiber-treating agent composition containing an oil-in-water-type emulsion wherein composition (A) containing the following component (b) is emulsified with the following component (a): component (a) : a polymer compound containing constituent unit (a1) having 2 to 20 carbon atoms in total and having at least one group selected from a hydroxy group, a carboxylic acid group, a quaternary ammonium group, an amino group and an amide group, provided that constituent unit (a2) is excluded, and constituent unit (a2) having a C8 to C22 hydrocarbon group, in a (a1)/(a2) molar ratio in the range of 100/30 to 1000/1, and component (b): a polyether-modified silicone having an HLB value of larger than zero to 7 or smaller.

Abstract: The invention provides a fiber treating composition comprising an oil-in-water emulsion prepared by adding (c) water to a mixed solution (A) having a component (a) /component (b) in a ratio of 1/150 to 30/100 by weight under stirring and then emulsifying the mixture, wherein the component (a) is a polymer compound containing a constituent unit (a1) containing 2 to 20 carbon atoms in total and having one or more groups selected from a hydroxy group, a carboxylic acid group, a quaternary ammonium group, an amino group and an amide group (provided that a unit constituting (a2) is excluded) and a constituent unit (a2) having a C8 to C22 hydrocarbon group, wherein the molar ratio of (a1)/(a2) is 100/30 to 1000/1, and the component (b) is a hydrophobic component capable of being dissolved in an amount of 1% by weight at the maximum in 100 g of water at 20° C. and having a saturated vapor pressure of 1.45 kPa (11 mmHg) or less at 20° C. and 0.1 MPa (1 atm).
