Latest Patents
Miyagawa's latest patents include innovative designs for impellers and compressors. One of his notable inventions is a method for producing an impeller, which features a hub that is rotatably supported about an axis of rotation. The diameter of the hub increases from the upstream to downstream sides along the fluid flow. A plurality of impeller blades extend radially outward from the outer circumferential surface of the hub. The design includes a cylindrical shroud that also increases in diameter from upstream to downstream, joining the outer circumferential ends of the impeller blades. This configuration enhances the reliability and performance of the impeller and compressor.
Another significant patent involves a manufacturing method for an impeller. This method includes forming a plurality of blades integrally on a blade attachment surface of either a disc or a cover. The process involves placing the cover on a floor with the blade attachment surface facing up, disposing the disc on the cover with the blade attachment surface facing down, and bonding the blades to the other surface using a bonding material. This innovative approach streamlines the manufacturing process and improves the overall quality of the impeller.
