Abstract: The invention discloses a method for forming a conductive polymer with an electrophoretic deposition cell, into porous anode for electrolytic capacitors. The conductive polymer is directly deposited on the oxide layer of the anode body. The electrolytic polymerized conductive polymer material form the cathode in solid electrolyte capacitors. The method allows low ESR capacitors to be produced. The invention provides a high yield and low cost industrial process with efficient materials utilization. The present invention successfully deposits particles from dispersion on continuous, highly insulating dielectric layers using electrophoretic deposition by use of EPD voltage near or above the anode dielectric formation voltage, where the anode body is positively biased relative to the EPD counter electrode, thereby allowing a current to be driven through the dielectric layer.

Abstract: The invention is a high capacitance capacitor anode manufactured by creating a green anode body from particles of a dielectric oxide film-forming electrical conducting non-agglomerated powder, sintering the green anode body, and anodizing the sintered body. The non-agglomerated powder comprises fine particles having a small average particle size and a narrow size distribution, which gives the green anode body a morphology that allows it to be sintered at temperatures lower than 1200° C. The invention is also a method of manufacturing these anodes.

Abstract: The invention is an apparatus, methods and systems for the production of coatings or small components having defined pre-set dimensions and properties by electrophoretic deposition (EPD) on electrically conducting or semi-conducting substrates. The invention provides efficient and precise mass manufacturing of components by EPD, such as anodes of electrolytic capacitors, by achieving high utilization of expensive raw materials and by consistently achieving tight dimensional tolerances of defined component shapes in repeated depositions. This includes production sequences of discrete components, batches of components, and production by semi-continuous operation.

Abstract: A novel electrically power heater for heating samples to very high temperatures is disclosed. The heater includes a heater base having a plurality of concentric circular rings. Each ring includes a plurality of heat lamps coupled to the heater body. The height of each concentric ring is variable and be set during design to any desirable height. In one embodiment, the height of each of the concentric rings is adjusted so as to form a contiguous upwardly sloping arc from the outermost ring to the innermost ring. In another embodiment, the height of the concentric rings is adjusted so as to form a combination of upwardly and downwardly sloping arcs. In both embodiments, the lower surface of the heater body is shaped to form a reflector. The reflector for each ring consists of two portions, each substantially elliptically shaped so as to greatly reduce back reflections through the filament of the heat lamp.
