Title: Etsuji Iwami: An Innovator in Cathode Ray Tube Technology
Introduction
Etsuji Iwami, an accomplished inventor based in Hitachi, Japan, has made significant contributions to the field of display technology. With a total of eight patents to his name, Iwami's innovative work has advanced the production methods of cathode ray tubes, showcasing his expertise and commitment to technological progress.
Latest Patents
Iwami's most recent patent involves a unique method for constructing a cathode ray tube. This method consists of several steps, including the positioning of a non-reflective transparent plate in front of a face plate of the tube body, creating a specific space between them. A resin composition is then employed to fill this space, and subsequent heating hardens the composition, effectively bonding the tube body to the transparent plate. The unsaturated polyester resin composition used in this process is designed for rapid molding without inducing strain during hardening, serving as an effective adhesive in cathode ray tube production.
Another notable invention of Iwami's is related to concrete-protective material, further highlighting his versatility as an inventor within the materials domain.
