Title: Fe-base constant-permeability magnetic core
Inventor: SAWA TAKAO
IPC: H01F1/14
Filed: 1992-12-14
Abstract: PURPOSE:To increase the saturated magnetic flux density, reduce the loss, and improve the DC superimposing characteristic of the title magnetic core in a high frequency region by making the core to have an Fe-base crystal phase and amorphous phase and controlling the average particle diameter of the crystal phase within a specific range. CONSTITUTION:The Fe-base alloy used for the title magnetic core has an Fe-base crystal phase and amorphous phase and, at the same time, the crystal phase is composed of fine crystals having an average particle diameter of 35-60nm. When the average particle diameter is <35nm, the coercive force of the magnetic core becomes weak and the core cannot have a sufficient constant-permeability. When the average particle diameter exceeds 60nm, on the other hand, the magnetic characteristics of the magnetic core, such as the iron loss, etc., deteriorate and the magnetic core cannot be used in a high frequency region. The magnetic core can be improved in DC superimposing characteristic when the coercive force is adequately increased without deteriorating much the magnetic characteristics, such as the iron loss, etc., nor providing any gap by controlling the average particle diameter of the crystal phase within a specific range. In other words, the magnetic core is less in loss and excellent in DC superimposing characteristic, namely, is excellent in constant-permeability in a high frequency region.

Abstract: PURPOSE:To promote low impedance advancement in a high frequency region by forming an organic semiconductor layer in an anode foil which is made by providing a valve metallic foil with a dielectric film, and forming a conductive polymer layer by using an aqueous solution of electrolytic polymeric monomer that the part of an anode foil, which is divided and isolated by an insulator layer formed at the specified layer, is dissolved by a supporting electrolyte. CONSTITUTION:An organic semiconductor layer 15, which is insoluble in water and soluble in organic solvent, is formed by a formation method at the anode drawing-out part of an anode foil 11 that a valve metallic foil is roughened and a dielectric film is provided by an anodizing process.
