Title: Takashi Maeno: Innovator in Power Transmission Technology
Introduction
Takashi Maeno is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of power transmission technology, holding a total of 17 patents. His innovative work has been instrumental in advancing mechanical coupling mechanisms and vibration-type actuators.
Latest Patents
Among his latest patents, Maeno has developed a power transmitting mechanism and method that mechanically couples a driving source to a driven member. This mechanism features a first member linked to the driving source and a second member connected to the driven member. A resilient member applies a force to ensure that the first and second members maintain pressure contact at a contact surface. Notably, a vibration is excited in the contact surface of the first member, producing a levitation force based on ultrasonic levitation, which acts upon the second member. The frictional force between the two members is modulated depending on the levitation force, thereby adjusting the power transmitted between them.
Another significant patent is for a control apparatus for a vibration-type actuator. This apparatus is designed to excite at least three kinds of vibrations, enabling the actuator to perform desired motions with high efficiency. The vibration-type actuator comprises a rotatable moving member, an elastic member in contact with the moving member, and an electro-mechanical energy conversion element that generates at least three different kinds of vibrations in the elastic member through periodic signals with varying phases. The control apparatus includes a rotation axis determining unit, a parameter determining unit, and a control circuit to optimize the actuator's performance.
