20130100585 | ELECTROCONDUCTIVE POLYMER SUSPENSION AND METHOD FOR PRODUCING THE SAME, ELECTROCONDUCTIVE POLYMER MATERIAL, AND SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING THE SAME - The present invention provides an electroconductive polymer suspension for providing an electroconductive polymer material with a high electroconductivity and a method for producing the same, and particularly provides a solid electrolytic capacitor with a low ESR and a method for producing the same. It includes a first step of carrying out chemical oxidative polymerization of a monomer providing an electroconductive polymer by using an oxidant in a solvent containing a first dopant including an organic acid or a salt thereof to synthesize an electroconductive polymer; a second step of purifying the electroconductive polymer; a third step of adding a second dopant, mixing an oxidant, subsequently adding a third dopant, and further mixing an oxidant in an aqueous solvent containing the purified electroconductive polymer; and a fourth step of carrying out an ion-exchange treatment to the mixture liquid obtained by the third step to obtain an electroconductive polymer suspension. | 04-25-2013 |
20130120098 | INDUCTOR - An inductor comprises a magnetic core and a coil. The magnetic core has a wound portion around which the coil is wound, and a peripheral portion. The magnetic core is formed from two or more preliminarily-formed-bodies which are pressure-molded in a state where the coil winds one or more preliminarily-formed-bodies which form the wound portion. The preliminarily-formed-bodies include at least one preliminarily-formed-body which forms the peripheral portion while not form the wound portion. Each of the preliminarily-formed-bodies is made of a mixture of flat magnetic powders and an organic binder so as to have a plate-like shape. The flat magnetic powders are oriented so as to be parallel to the preliminarily-formed-body. | 05-16-2013 |
20130135790 | ELECTROCONDUCTIVE POLYMER COMPOSITION, ELECTROCONDUCTIVE POLYMER MATERIAL, ELECTROCONDUCTIVE SUBSTRATE, ELECTRODE AND SOLID ELECTROLYTIC CAPACITOR - The problem is to provide an electroconductive polymer composition in which, when a layer containing an electroconductive polymer material is formed, the thickness can arbitrarily be controlled and the layer has a high electroconductivity.
