Title: The Ingenious Innovations of Hiroshi Shimada

Introduction

Hiroshi Shimada, a distinguished inventor hailing from Nagai, Japan, has made significant contributions to the field of capacitors. With a total of three patents to his name, Shimada's work particularly focuses on electrolytic capacitors, showcasing both innovation and practicality in design and functionality.

Latest Patents

One of Shimada's latest inventions is an electrolytic capacitor designed to withstand high internal pressures caused by electrolytically generated hydrogen gas. This advanced electrolytic capacitor comprises an electrolytic liquid enclosed in a closed container, featuring at least one pair of anode and cathode foils alternately superimposed and coiled together, spaced apart by insulating spacers.

Additionally, it incorporates a semipermeable membrane element that allows hydrogen gas to permeate while preventing the electrolytic liquid from escaping. The membrane is engineered to exhibit a hydrogen gas-permeating rate of 3.6 cm³/cm²·1000 hours or more at 50°C and a water vapor-permeating rate of 2000 cm³/cm²·1000 hours or less, facilitating long-term usage without rupture.

Another of his significant contributions includes a process for producing electrolytic capacitors with extremely thin spacer layers. This innovative production method involves coating anode and cathode foils with a photosensitive polymer resin, followed by a precise masking and irradiation process to create thin spacer layers, ensuring the efficient design and functionality of capacitors.
