Filed: 1993-07-07
Abstract: PURPOSE:To realize a noise absorber and a small noise filter both more enhanced in performance by a method wherein one or more granular magnetic substances specified in grain diameter are dispersed in a non-magnetic insulator. CONSTITUTION:A noise filter is formed through such a method that a structure composed of a non-magnetic insulator 2 and a film of magnetic substance 1 bonded to the single side or both the sides of the insulator 2 is rolled into a single-layered or multilayered cylinder. The magnetic substance 1 is formed of NiFe and CoZrNb, and the non-magnetic insulator 2 is formed of SiO2. One or more granular substances of grain diameter 0.1 to 10 times as large as a skin depth are so dispersed in the non-magnetic insulator 2 as to be separated from each other by a distance of 50nm or above. By this setup, a noise absorber enhanced in performance taking advantage of an eddy current lass can be obtained, and furthermore a small noise filter can be also obtained.

Filed: 1986-07-17
Abstract: PURPOSE:To achieve a separating operation efficiently with a reduction in the time and labor therefor, by adding a reference spectrum to an energy spectrum, for which it is separated, again before performing a main separating operation, when a residual peak exists after the reference spectrum is separated from the energy spectrum. CONSTITUTION:A distribution curve such as Gaus distribution and Lorentz distribution is selected for peaks P1 and P2 included in an energy spectrum obtained by measuring a sample and peak position, expansion rate or the like thereof are adjusted to make the curve fit the peaks P1 and P2 so that reference spectrums S1 and S2 are generated (a) and (b). Thereafter, the spectrums S1 and S2 are subtracted from the energy spectrum to separate. At this point, when residual peaks P1, P2 and P3 exist as shown by (c), the spectrum S1 thus separated is added to the energy spectrum again after the separation thereof and a distribution curve is selected as previously, and a new reference spectrum S'1 is formed (d) to make the curve fit peaks. Then, the spectrum S'1 is separated (e) by subtraction.
