Title: Innovations by Takashi Itoh

Introduction

Takashi Itoh is a notable inventor based in Yokkaichi, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced cable technologies. With a total of four patents to his name, Itoh's work focuses on enhancing the performance and durability of electrical wires.

Latest Patents

One of Takashi Itoh's latest patents is for a waterproof cable and method of manufacture thereof. This innovative cable features a plurality of conductive strands twisted together to form a wire core, which is then surrounded by an insulation layer. A water-absorptive swellable powder is applied to the individual strands prior to twisting, allowing it to fill the spaces between adjacent strands. This design effectively seals the cable against water penetration, ensuring its reliability in wet conditions. The manufacturing process involves spraying a solution of the powder onto the strands, followed by solvent evaporation to leave the powder adhered to the surfaces.

Another significant patent by Itoh is for a heat-proof electric wire that incorporates a benzimidazole-based polymer coating. This insulating material consists of a benzimidazole-based polymer layer combined with a fluorine-containing rubber layer, providing exceptional heat resistance. The manufacturing process includes soaking an electric wire in a varnish solution of partially polymerized benzimidazole-based polymers, followed by heating to cross-link the polymers. This results in a durable wire that is also resistant to dielectric breakdown.
