With a total of 3 patents, Kawai's work reflects his commitment to innovation and precision in manufacturing processes.

Latest Patents

One of Kawai's latest patents is a laser beam machining device. This device employs a laser for generating a laser beam, a chopper device for intermittently blocking the laser beam, and an assisting gas discharge device for injecting assisting gas toward the point where the laser beam is irradiated. By positioning the chopper upstream of the primary condenser and away from the assist gas flow, the device ensures that the assist gas is not disturbed, which could otherwise degrade the precision of the laser beam machining operation. Additionally, the assisting gas discharging device is designed to direct the assist gas flow substantially along the axis of the laser beam.

Another significant patent is a method and apparatus for cooling rolling mill rolls. This roll cooling device comprises cooling water guide plates with a curved surface along the circumferential direction of the rolls. The guide plates are positioned close to the rolls and are supported by members that allow for curvature adjustments based on the diameter of the rolls. This design ensures that the clearance between the guide plate and the roll is maintained, providing effective cooling even when the roll diameter changes significantly.
