Title: Yasumasa Watanabe: Innovator in Sheet Material Inspection Technology
Introduction
Yasumasa Watanabe is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of inspection technology for traveling sheet materials. With a total of 2 patents, his work focuses on enhancing the accuracy and efficiency of defect detection.
Latest Patents
Watanabe's latest patents include a method and apparatus for inspecting traveling sheet material. This innovative method aims to replicate the identifying ability of human visual inspection as closely as possible. The detected defects are converted into electrical signals and categorized into four factors: width, quantity, depth or density, and length. This categorization allows for a more economical sorting process. The factors are then classified into high, medium, or low classes, and a decision circuit synthesizes the discriminated defect factors according to a defect pattern.
Another significant patent is a system for determining the transversal position of any defect in a traveling sheet material. This system utilizes a defect detector and at least one scanning detector. The transversal position of the defect is determined by the coincidence between a defect signal from the defect detector and an output signal from the scanning detector.
