Abstract: A method for forming solid electrolytic capacitors provides for anode lead and body surface with increased dielectric thickness as distinguished from a dielectric thickness formed within the inner anode body such that a capacitance value associated therewith is not substantially decreased. The method includes the steps of anodizing the anode to form a predetermined dielectric thickness on the anode and then soaking the anode in a solvent to impregnate an inner portion thereof with the solvent. The solvent is removed from surface areas desired to be coated by a further dielectric layer and thereafter again anodized whereby additional dielectric build-up is limited to the solvent free areas. The solvent is driven off resulting in a capacitor preform which is reinforced by thickened dielectric without capacitance loss which would result from depositing additional dielectric interiorly in the areas insulated from build-up by the solvent.

Abstract: Syndiotactic polypropylene is blended with isotactic polypropylene and the blend melt processed into medical articles. The blends have molding cycle times which are up to 12 times shorter that for pure syndiotactic polypropylene.

Abstract: A marginless electrical component, such as a capacitor, is fabricated by providing a multilayer body of electrodes and dielectric with an insulating layer on alternate electrodes on each terminated surface.

Abstract: A self supporting gel includes a gelling agent and an electrolyte dissolved in a solvent. The gel is conducting and may be used in a battery.

Abstract: A method of manufacturing solid state capacitors involves providing an elongate band of solid state forming metal, folding the band into a trough-like U-shaped configuration, introducing a layer of solid state metal powder into the trough, sintering the powdered metal to thereby bond the metal to the foil, partially severing the foil and sintered powder to define a multiplicity of individual units which are thereafter processed to convert the units into capacitors by sequential dielectric forming and counterelectrode depositing steps. The individual capacitors are terminated and preferably also may be tested while still interconnected by portions of the foil, following which individual capacitors are separated by cuts which register with the initial cuts which defined the individual units. The disclosure further teaches a novel solid state capacitor fabricated in accordance with the method, the capacitor exhibiting high volumetric efficiency and being particularly adapted for surface mounting.
