Latest Patents

Usui's latest patents include a method for molding composite material and a device for molding composite material. These inventions aim to suppress the occurrence of voids in composite materials while improving their mechanical characteristics and appearance quality. The method involves creating a seal region that includes a cavity for a reinforcing base material, which is air-tight sealed. A gas is suctioned from the outer peripheral region to evacuate the gas in the seal region, followed by the injection of resin into the cavity. This process is completed by clamping a mold to ensure a liquid-tight seal, allowing the resin to fill the cavity effectively.

Another notable patent is a surface treatment device and method. This device features a vacuum blast head that includes an injection nozzle and a suction hole. The nozzle injects a polishing agent for blast treatment, while the suction hole collects the agent with suction air. An air curtain-forming unit surrounds the injected polishing agent, enhancing the treatment process.
