Title: Innovations by Shuji Nakata
Introduction
Shuji Nakata is a notable inventor based in Toyonaka, Japan. He has made significant contributions to the field of electronic components and welding technology. With a total of 7 patents to his name, Nakata's work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a method and device for checking the joint of an electronic component. This innovative approach applies heat energy to a joint containing a heat conductive material and utilizes an infrared camera to receive the infrared rays radiated from the joint. By processing the image information from the infrared camera, the method can provide details such as the area of a defect, area ratio of a defect, pixel coordinates, temperature distribution pattern, distance between central axes of a particular portion of the joint, and gradient angle. The obtained values are then compared with predetermined values to determine the type of defect and whether the joint is defective.
Another significant patent is a method and system for determining weld quality in resistance welding. This system assesses acceptance or unacceptance by comparing the electrode voltage, electrode current time, number of electrode voltage pulse signals exceeding reference values, and the integral of the difference between the electrode voltage and a base voltage. This relatively low-cost system can accurately determine weld quality, even when the electrode tips are deformed or crushed.
