Title: Innovations in Cathode Ray Tube Technology: The Patents of Hua-Sou Tong

Introduction: Hua-Sou Tong, an accomplished inventor based in Arlington Heights, IL, has made significant contributions to the field of color cathode ray tube (CRT) technology. With a total of 22 patents to his name, his work has greatly influenced the design and performance of CRT displays, ensuring enhanced color purity and image clarity in televisions and monitors.

Latest Patents: Two of Hua-Sou Tong's latest patents focus on thermal management and shadow mask mounting arrangements in color CRTs. The first patent addresses thermal expansion issues related to shadow mask holders. It incorporates a mounting stud that connects to the CRT's glass envelope along with resilient metal holders designed to maintain the shadow mask's alignment. By utilizing materials with low coefficients of thermal expansion, such as Invar, Neovar, or Kovar, this invention prevents misalignment caused by thermal expansion, thus preserving video image color purity.

The second patent presents a shadow mask mounting arrangement featuring four resilient metal holders. Constructed from unitary metal strips, these holders engage with the shadow mask's skirt and are spot welded to ensure stability. As the shadow mask deforms under heat from the electron beams, the holders facilitate a perpendicular deflection, keeping the mask's apertures aligned with the phosphor deposits. This design effectively maintains video quality and prevents degradation of color purity.

Career Highlights: Hua-Sou Tong's career includes notable tenures at leading technology firms, such as Chunghwa Picture Tubes, Ltd. and Zenith Electronics Corporation. His innovative spirit and technical expertise have led to advances that benefit the entire industry.
