Title: Mine Sumitomo: Innovator in Vibration Actuators
Introduction
Mine Sumitomo is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of technology, particularly in the development of vibration actuators. With a total of 2 patents to his name, Sumitomo continues to push the boundaries of innovation.
Latest Patents
His latest patents include a vibration actuator and a lens barrel for cameras. The vibration actuator features an elastic member and a relative movement member. The elastic member generates oscillatory waves through the oscillation of an electromechanical conversion element. The relative movement member, which is in pressure contact with the elastic member, is driven by these oscillatory waves to achieve rotational movement. Notably, at least one of the members has multiple spaces on one contacting face, filled with friction coefficient adjusting substances, allowing for a variable coefficient of friction in a radial direction.
Another patent, titled "Vibrational actuator and method for driving vibrational actuator," describes an oscillator that generates vibrational energy. This actuator includes a mover that is rotationally driven around a first axis by the vibrational energy. An output shaft rotates around a second axis using the rotational force communicated from the mover. A flange portion projects from the output shaft, rotating in conjunction with it. Pressure is applied to the mover between the flange portion and the oscillator, ensuring that the first and second axes remain aligned.
