Latest Patents

Among his latest innovations is the "Increased Slip Force Pivot Bearing." This invention features a sleeve of an actuator bearing cartridge with an inclined surface on its outer surface. A tolerance ring is placed around the sleeve, and both the cartridge and ring are press-fit into the actuator bore together. This design effectively prevents axial slippage of the ring and actuator relative to the cartridge by wedging the ring between the inclined surface and the inner surface of the actuator bore. Another significant patent is the "Piezoelectric Head Loading and Unloading Device for Rigid Disc Drives." This system is designed to load a transducing head to a flying elevation close to the rotating surface of a disc. It includes a piezoelectric device that is selectively expanded and contracted to control the height of the head on a flexure spring from the surface of the disc. The system also incorporates control circuitry for generating electrical control signals to manage the piezoelectric device's expansion and contraction based on the operating characteristics of the disc.
