Title: **Innovations by Yozo Yamada: A Pioneer in Functional Roll Film and Infrared Filters**
Introduction
Yozo Yamada, an accomplished inventor based in Ohtsu, Japan, has made significant contributions to the field of materials science and engineering. With a robust portfolio of 15 patents, Yamada has focused on innovative solutions that enhance functionality and efficiency, particularly in film technology and environmental stability.
Latest Patents
Two of Yamada's most recent patents exemplify his innovative spirit and technical expertise. The first patent relates to a **Functional Roll Film** and a vacuum evaporation apparatus capable of producing this film. This functional roll film consists of a transparent plastic film that possesses excellent gas barrier properties. It is uniquely designed with an inorganic oxide layer on at least one surface, with a maximum thickness 1.5 times greater than its minimum thickness, allowing it to be wound for various applications.
The second patent is for an **Infrared Absorption Filter**. This filter is engineered to have a transmittance of no more than 30% in the near-infrared region (800 to 1100 nm) and maintains a transmittance of at least 50% at a wavelength of 550 nm. Notably, it exhibits minimal variance in visible light transmittance, which supports optimal performance for plasma displays while ensuring high environmental stability. After being exposed to extreme conditions (60°C and 95% humidity for 1000 hours), the filter retains its spectral properties, proving its durability and effectiveness in preventing erroneous operations of infrared remote controls in demanding environments.
