Title: Toshiki Shirahata: Innovator in Amorphous Core Technology
Introduction
Toshiki Shirahata is a prominent inventor based in Shibata, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of amorphous core transformers. With a total of 13 patents to his name, Shirahata's work has greatly influenced the efficiency and effectiveness of transformer technology.
Latest Patents
One of his latest innovations is the amorphous core transformer. This invention features an amorphous core constructed in such a way that multiple kinds of amorphous magnetic strips, having different widths, are arranged in abutting relation and laminated. The alternating arrangement of these strips allows for a displacement of the abutting surfaces, which drastically reduces the hours of wrapping work and improves working efficiency.
Another notable patent is the wound iron core for static apparatus, which enhances iron core characteristics by subdividing magnetic paths within the core. This design utilizes two or more kinds of magnetic materials with varying magnetic permeabilities to form laminated blocks. The arrangement of these blocks is carefully designed to ease excessive magnetic flux density distribution within the iron core. Additionally, Shirahata has developed a ring-shaped iron core that consists of block-like laminated members formed from strip-like amorphous material thin plates, further showcasing his innovative approach to transformer technology.
