Latest Patents
Seo’s patent, “Liquid Filling Method, and Device for Implementing the Same Method,” describes filling a narrow channel with a vaporized volatile substance before introducing an injection liquid under pressure. The vapor displaces air from the channel. When pressure is applied, the vapor condenses and changes into a liquid, reducing its volume and allowing the injection liquid to occupy the space it had filled. This approach addresses the challenge of filling narrow channels with closed ends.
