Title: Innovative Advances by Hiroaki Kuwano

Introduction: Hiroaki Kuwano is an accomplished inventor based in Yokosuka, Japan, known for his significant contributions to engineering and technology. With a total of six patents to his name, Kuwano's innovations focus on the optimization of strip material processing, showcasing his expertise in hydraulic technology.

Latest Patents: Among his latest patents is the Method and Apparatus for Steering Strip Material. This invention involves a steering device in the form of a pinch roll stand, which feeds strip material to a reduction rolling mill. The apparatus employs hydraulic cylinder units at the ends of the pinch rolls to apply strip gripping forces. It also features a reduction mill equipped with independent hydraulic cylinders that adjust the pressure of the reduction rolls across the strip. Additionally, sensors are strategically placed to detect the strip's position before both the pinch rolls and the rolling mill, with the collected data being sent to a controller that manages the operation of the hydraulic units to ensure precise steering.

Another remarkable patent is the Control Method of Hydraulic Pinch Roll and Control Unit Thereof. This control unit incorporates position detectors that monitor the pistons of the hydraulic cylinders. An arithmetical unit calculates the variance in outputs from the position detectors. The controller then processes the calculated differences to provide correction outputs, which are adjusted in a manner that corrects any discrepancies in the pressing force across the pinch rolls. This innovative technology effectively minimizes defective winding shapes during manufacturing.
