Latest Patents

Oka holds a patent titled "Method and apparatus for pressure sticking a thin film to a base plate." This invention describes an apparatus and method for pressure and heat sticking a thin film to a base plate. The process involves introducing the thin film and a base plate on a film-like carrier into a vacuum chamber. The chamber contains upper and lower contact members that compress the thin film, base member, and carrier into a stratified body. The design ensures that the thin film and base plate are initially held separate within the chamber. The lower contact member moves upward to make contact with the carrier and base plate, compressing the stratified body between it and the upper contact member. The upper contact member is convex and made of elastic material, allowing the contact pressure to start near the center and spread toward the periphery. This design results in improved adhesion of the thin film to the base plate without air bubbles or wrinkling. The process is conducted under vacuum or reduced atmospheric pressure, with simultaneous application of heat. A final compression at atmospheric pressure is achieved using a heat and pressure roller. Oka's innovative approach has led to advancements in the efficiency and quality of thin film applications.
