Latest Patents

Hirao's latest patents include a method for manufacturing an overrunning clutch. This invention involves the installation of rollers and springs in the notch portions of a clutch outer. The inscribed circle diameter of the rollers is measured while they are in contact with stopping portions, influenced by pressure from the springs. The outside diameter of a cylindrical portion is then determined to achieve a predetermined amount of roller bite. The final step involves finishing the outside diameter to the determined value. Additionally, he has developed a starter mechanism designed to prevent the attracting force to the plunger from becoming insufficient. This is achieved by forming at least one of an output shaft and a thrust spline from magnetic material with a lower relative permeability than iron.
