Title: The Innovations of Takao Tsuboi
Introduction
Takao Tsuboi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced wire technologies. With a total of 2 patents to his name, Tsuboi's work has had a considerable impact on the industry.
Latest Patents
Tsuboi's latest patents include innovations in copper alloy wire and insulated electric wires. The copper alloy wire features a composition that includes no less than 0.01% by weight of silver (Ag) and the balance being copper (Cu) along with unavoidable impurities. This wire is prepared by drawing a wire stock with a reduction ratio of no lower than 40% and is subjected to heat treatment for half annealing. This process results in a tensile strength of no less than 27 kg·f/mm² and an elongation of 5%. Additionally, the insulated electric wire incorporates this copper alloy wire as a conductor, with an insulation layer covering the wire. Tsuboi has also developed a multiple core parallel bonded wire, which consists of two or more insulated electric wires bonded parallel to each other. Another significant innovation is the stranded insulated wire, produced by applying a coating material containing polyvinyl butyral and a stabilized polyisocyanate to an enameled strands assembly, followed by baking the assembly.
