Title: The Innovative Contributions of Hidemi Ikai
Introduction
Hidemi Ikai is a prominent inventor based in Kariya, Japan. She has made significant contributions to the field of engineering, particularly in the development of pump devices and vehicular brake systems. With a total of 4 patents to her name, her work exemplifies innovation and practicality in design.
Latest Patents
One of her latest patents is a pump device that features a unique bearing arrangement. In this design, the movement of an outer race in the longitudinal direction of a drive shaft is restricted, while the drive shaft is fixed to an inner race through a press fit. This configuration prevents the drive shaft from escaping and allows for a longer inner race compared to the outer race. As a result, the pump device can be made smaller while enhancing the reliability of the function that prevents the drive shaft from escaping. Another notable patent is her vehicular brake device, which includes a cylindrical first case housing multiple rotary pumps and a second case located coaxially with the first. A disk spring is positioned between the two cases, and a fixing means at the entrance of the concave portion of the housing presses the second case in the insertion direction of the pump body, ensuring a secure fit.
