Latest Patents

Kawamoto's latest patents include a "Disk system with sub-actuators for fine head displacement." This invention utilizes both a voice coil motor and a piezoelectric element on a head supporting arm to precisely position a head on a disk. The piezoelectric element is strategically built into the distal end of the arm and is restricted in movement by a resilient mechanism designed to have low rigidity in the driving direction and high rigidity in other directions. This mechanism is formed by pairs of doubled parallel leaf springs arranged on either side of the piezoelectric element.

Another notable patent is the "Method of and apparatus for conveying object by utilizing vibration." This invention features a vibrating-type driving unit that employs a piezoelectric device to convey objects, such as sheet materials. A follower roller is positioned opposite the driving unit, and A.C. power is supplied to facilitate the conveyance. The friction coefficient of the follower roller's surface is selected to be greater than that of the driving head, allowing for efficient and stable object conveyance.
