Latest Patents

Kumazawa's latest patents include a "Method and device for removing defective products" and a "Method of manufacturing a heat exchanger." The first patent discloses a device designed to remove defective products from a continuous feed path. This device incorporates a feeder for product delivery, a sensor for detecting defects, and a remover that extracts defective items. The sensor signals defects in either the trailing half of one product or the leading half of an adjacent product. The remover operates based on a calculated quotient derived from the distance between the sensor and the remover, ensuring efficient removal of defective products.

The second patent focuses on the manufacturing process of a heat exchanger, such as a radiator for automotive engines. This method involves fixing lengths of flattened tubes and corrugated fins through brazing in a furnace. The flattened tube is created by bending a strip and welding its edges, followed by applying pressure to form a tube with a circular cross-section. This innovative approach also includes the application of brazing material to repair any minor weld defects, enhancing the overall quality of the heat exchanger.
