Title: Inventor Yasuyoshi Makino: Innovations in Centrifugal Blowers

Introduction

Yasuyoshi Makino is a notable inventor based in Tokyo, Japan, with an impressive portfolio of five patents. His work primarily focuses on advancements in centrifugal blower technology, reflecting his commitment to innovation in engineering.

Latest Patents

Two of Makino's latest patents demonstrate his ingenuity in the design of centrifugal blowers. The first, titled "Multiblade Centrifugal Blower," encompasses a centrifugal fan that includes a hub rotated by a motor, featuring multiple curved rectangular blades arranged at precise intervals. This design creates a cylindrical basket with an opening at the front of the hub, paired with a scroll casing that contains an air inlet and an air outlet. The innovative aspect lies in the configuration where the length from the rear end to the front end of an outer edge of the blade is intentionally shorter than that of the inner edge. Additionally, the bell mouth design minimizes the distance between the inner edge of the blade and the scroll casing's inner wall.

The second patent, labeled "Centrifugal Multiblade Fan," involves a similar concept where a plurality of curved rectangular blades are positioned around the periphery of a disc. This pipe-like basket shape incorporates an opening on the front side of the disc. As the disc rotates, air is drawn in from the opening and expelled in a centrifugal direction through the space between the blades. Notable features include the thick and thin plate parts of the blades, enhancing aerodynamic performance.
