Latest Patents

Watanabe's latest patents include a pressure vessel and a method for winding filament. This invention allows a reinforcing layer to maintain an even thickness. The pressure vessel consists of a liner with a hollow portion and a reinforcing layer that encircles the liner. The reinforcing layer is constructed by binding bands made of reinforced fibers around the liner, ensuring a layered structure. Additionally, a lap portion is created where the ends of adjacent bands overlap, with at least one end of the bands being thinner than the rest.

Another significant patent is a pressure vessel featuring an improved sealing arrangement. This design includes a resin liner with a tubular extension that defines a through hole for gas or liquid expulsion. A tubular member is fitted into this extension, along with a mouthpiece and a fiber-reinforced resin layer surrounding the liner. The valve integrated into the tubular member is designed to ensure optimal sealing performance under various pressure conditions, thanks to a resilient seal member placed in the gap between the valve and the tubular member.
