Title: Katsuhiro Takahashi: Innovator in Optical Technology and Battery Design
Introduction
Katsuhiro Takahashi is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the fields of optical technology and battery design. With a total of 4 patents to his name, his work has had a considerable impact on modern technology.
Latest Patents
One of his latest patents involves an innovative optical disk design. This optical disk features a hub at the central portion of a substrate. A specific relationship, Y/X ≥ 0.015, preferably Y/X ≥ 0.05, is maintained, where X represents the projected area of the substrate and Y denotes the contact area between the hub and the substrate. This design prevents slippage between the hub and the substrate, even at higher rotational speeds than conventional disks. As a result, the data transfer rate is enhanced, and issues such as irregular rotation and camming are minimized, leading to reduced tracking and write/read errors.
Another notable patent is for a valve-regulated lead-acid battery. This invention specifies that the theoretical capacity (Ah) of the negative active material in the battery is less than that of the positive active material. The amount of conductive additive, such as carbon, added to the negative active material ranges from 0.5 weight % to 7.5 weight %. The conductive additives include carbon, acetylene black, polyaniline, and tin powder, all with an average particle diameter of 100 micrometers or less.
