Title: **The Innovative Journey of Masakazu Hosogi**
Introduction
Masakazu Hosogi, an accomplished inventor hailing from Shimane, Japan, has made significant contributions to the field of electronics through his innovative designs. With a total of 10 patents to his name, he stands out for his work on electrolytic capacitors, showcasing his ingenuity and expertise in this specialized area.
Latest Patents
One of Hosogi's latest patents focuses on an electrolytic capacitor that incorporates a unique design. This capacitor comprises a capacitor element that holds a predetermined liquid preparation between a pair of electrodes, which are separated by a separator. The body case houses the capacitor element, while a rubber sealing member securely seals the body case. An innovative supplying portion is designed to contact the sealing member, allowing for the transfer of the liquid preparation. The liquid preparation contains a lipid-soluble sealing member deterioration preventing agent, which is dissolved in a lipophilic solvent. The careful balance of the agent's weight in the sealing member guarantees durability, as it permeates the sealing member and prevents deterioration.
Another of Hosogi's patents further refines the electrolytic capacitor concept. This design also features a capacitor element, holding a solution between an anode foil and a cathode foil wound with a separator in between. The capacitor element is encased in a body case, which is secured by a sealing member. Notably, part of the separator makes contact with the sealing member, ensuring effective interaction. The solution includes a deterioration preventing agent that solidifies upon oxidation and is delivered through the separator to coat the sealing member effectively.
