Title: Taketoshi Shimona: Innovator in Electron Gun Technology
Introduction
Taketoshi Shimona is a notable inventor based in Isesaki, Japan. He has made significant contributions to the field of electron gun technology, holding a total of 3 patents. His work primarily focuses on advancements in cathode ray tubes, which have been pivotal in the development of display technologies.
Latest Patents
One of Shimona's latest patents is an electron gun assembly for a color cathode ray tube. This innovative assembly generates three in-line electron beams from three cathodes, which are controlled and accelerated by a prefocusing electron lens. Each beam is converged by a unipotential electron lens, ensuring that they are correctly focused on a screen. In addition, the electron beams are collimated by quadruple lenses in a horizontal plane and emerge as divergent beams in a vertical plane, ultimately converging at a point by the main electrode lens.
Another significant patent is for a cathode ray tube that features an electron gun assembly. This assembly includes a plurality of electrodes that generate electron beams and an electron lens unit that focuses these beams onto a phosphor screen. The design incorporates insulating support rods, a resistor unit for voltage application, and terminal voltage pickup terminals to maintain image quality and prevent discharge.
