Title: Yuzuru Watanabe: Innovator in Electron Gun Technology
Introduction
Yuzuru Watanabe is a notable inventor based in Fukushima, Japan. He has made significant contributions to the field of electron gun technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and accuracy of electron guns used in various applications, including color cathode ray tubes.
Latest Patents
One of Watanabe's latest patents is a method and apparatus for detecting position deviation of an electron gun. This innovative approach increases light utilization efficiency, making the field of sight lighter. By reducing the amount of reflected light from the grid surface, the reflected light from the electron beam emitting surface becomes clearer, allowing for accurate detection of position deviation. The method employs linear polarized light to illuminate the electron gun, with a light polarization unit observing the reflected light to determine the position deviation between the grids of the electron gun.
Another significant invention by Watanabe is an advanced electron gun designed for use in color cathode ray tubes. This electron gun is engineered to achieve optimal focus conditions for electron beams, even when deflected in a convergence-free deflecting magnetic field. By adjusting the converging angle in the vertical direction to be smaller than that in the horizontal direction, Watanabe's design ensures that both the center and corner electron beams are focused effectively.
