Title: Taketoshi Shimoma: Innovator in Cathode Ray Tube Technology
Introduction
Taketoshi Shimoma, located in Isesaki, Japan, is a prominent inventor known for his significant contributions to the field of display technology. With an impressive portfolio of 24 patents, Shimoma has become a key figure in the development of color cathode-ray tube apparatus that has advanced electronic display systems.
Latest Patents
Among his recent patents, Shimoma has designed a color cathode-ray tube apparatus that innovatively enhances the electron gun assembly. His work outlines that electron beams emitted from cathodes are focused in a first cross-over, subsequently accelerated and controlled by grids aligned along three axes. This meticulous arrangement allows the weakly converged electron beams to be further manipulated by unipotential lenses before being converged by a specially designed single electron lens. The lens's power adjusts according to the horizontal or vertical deflection of the beams, ultimately forming a second cross-over. The diverged electron beams are then precisely focused onto a phosphor screen by a main lens. Another substantial patent involves the deflecting unit of the color cathode ray tube, which incorporates a main deflecting section and at least one sub-deflecting section to optimize the deflection and enhance the display quality.
Career Highlights
Taketoshi Shimoma's career is distinguished by his association with notable companies, particularly Toshiba Corporation and Tokyo Shibaura Electric Co., Ltd. His tenure at these companies has facilitated his growth as an inventor and has greatly influenced the field of display technology.
Collaborations
Throughout his career, Shimoma has collaborated with esteemed colleagues such as Kumio Fukuda and Jiro Shimokobe. These partnerships have not only enriched his work environment but have also contributed to the innovative spirit that defines his inventions.
Conclusion
In conclusion, Taketoshi Shimoma stands out as a pioneering inventor in the realm of color cathode-ray tube technology. His groundbreaking patents continue to shape the future of electronic displays, showcasing the impact of his ingenuity and collaboration in the field.
