Latest Patents

Among his latest patents is the "Electrolytic capacitor containing a hydrochloric acid electrolyte." This invention utilizes an anodized porous tantalum pellet and employs an azeotrope of hydrochloric acid and water, ideally containing about 20 wt % hydrochloric acid as the electrolyte. Another significant patent is "Making a capacitor employing a temporary solid mask in the porous anode." In this process, formed porous tantalum pellets with an extending anode wire are partially immersed in molten compounds like naphthalene, which wicks into the pellet pores. After freezing, a liquid insulating material is applied to the anode wire while being masked from entering the porous pellet by the naphthalene. The naphthalene is then vaporized, allowing manganous nitrate to be introduced and pyrolyzed to form MnO2.
