Title: The Innovative Contributions of Yoshihisa Ito
Introduction
Yoshihisa Ito is a notable inventor based in Anjo, Japan. He has made significant contributions to the fields of engineering and technology, holding a total of 4 patents. His work primarily focuses on advancements in transmission systems and refrigeration technologies.
Latest Patents
One of his latest patents is for a continuously variable transmission. This invention features a hydraulic actuator designed for axially moving a movable sheave. The outer cylinder of the actuator includes a radial portion that extends from a boss on the stationary sheave. A bearing is positioned to abut the surface of this radial portion, with the inner race of the bearing having a large diameter to ensure contact with a predetermined area of the surface. This design includes a recess on one side of the inner race for a nut that axially fixes the outer cylinder and bearing, effectively reducing the axial dimension of the transmission.
Another significant patent by Ito is for a cryogenic refrigerator. This invention utilizes first and second refrigerating circuits that alternately cause first and second adsorbing bodies to absorb and release coolants. The first refrigerating circuit allows the first adsorbing body to release coolant when heated, which is then cooled and discharged through an expansion valve. This process liquefies part of the coolant, utilizing the latent heat of vaporization to cool objects. The second refrigerating circuit operates similarly, enhancing the efficiency of the cooling process.
