Latest Patents
Yagi's latest patents include a reforming apparatus and a method of operating the same. The objective of this invention is to provide a reforming apparatus capable of uniformly mixing water (steam) and a raw material together. It prevents the precipitation of carbon without the need for a temperature controller and efficiently heats the water and mixture using heating gas. The apparatus features a first vaporizer and a second vaporizer, both cylindrically shaped, with a duct connecting their flow passages. The design allows for effective heating and mixing, resulting in superheated steam that flows through a reforming-catalyst layer.
Another significant patent is the tapered coupling structure and rotating machine. This invention allows a tapered shaft to be coupled to and decoupled from a hub without the use of an O-ring. The tapered shaft includes a taper part that connects to the hub, which is designed with a high-rigidity part to enhance stability. An oil groove is incorporated to feed oil to the coupling surfaces, ensuring smooth operation.
