Latest Patents

Yoshida's notable patent is titled "Aluminum Solid Electrolytic Capacitor and Manufacturing Method Thereof." This invention specifically addresses the design and manufacturing techniques of aluminum foil-type solid electrolytic capacitors. The patent highlights how the distance between the two foils in the capacitor element is determined by the thickness of the separator, which is carefully maintained between ten to sixty micrometers. The solid electrolyte is formed via the thermal decomposition of an impregnated electrolytic solution, ensuring optimal performance.

The manufacturing method specified in the patent outlines the creation of an aluminum foil-type solid electrolytic capacitor with a manganese dioxide electrolytic layer positioned between the electrode foils. This layer is formulated through the thermal decomposition of the electrolytic solution under controlled conditions of temperature (between 200 and 260 degrees Celsius) and time intervals (between 20 and 40 minutes). The procedure also details the incorporation of fine powders of manganese dioxide and the potential doping of lithium into the layer, alongside electrochemical processes for restoring an aluminum oxide film. Additionally, methodologies for producing chip-type aluminum solid electrolytic capacitors are described, including enhancements for fixing the capacitor element within a resin-fitted case or electrically connecting it to a metallic case.
