Latest Patents

Among his latest patents, the "Winding Mechanism with Tension Control Function" stands out. This invention aims to eliminate excessive tension or slack in a wire wound around a drum, ensuring a constant tension or wire length. The mechanism utilizes a reversibly rotatable liquid-pressure motor to rotate the drum, coupled with a liquid-pressure pump that supplies hydraulic oil. An electric motor drives the pump, while a control unit manages the torque of the motor based on load current variations, maintaining the wire tension at a set value.

Another significant patent is the "Hoisting Device with Vertical Motion Compensation Function." This device is designed to be compact and energy-efficient. It features a hoist that rotates a drum with a wire wound around it, powered by an oil pressure motor. The control unit of the hoisting device uses an acceleration/displacement transducer to determine the moving direction and speed of the wire hanging point, compensating for vertical motion caused by hull heaving.
