Latest Patents
Akutsu holds 2 patents that showcase his expertise in inspecting traveling sheet materials. His first patent is titled "Method of and an apparatus for inspecting a traveling sheet material." This invention aims to replicate the identifying ability of human visual inspection as closely as possible. The method converts detected defects into electrical signals, which are then categorized into four factors: width, quantity, depth or density, and length. This categorization allows for a more economical sorting process, with defects classified as high, medium, or low class. The discriminated factors are then synthetically judged through a decision circuit based on defect patterns.
His second patent, "System for determining a transversal position of any defect in a traveling sheet material," involves a defect detector and at least one scanning detector. This system determines the transversal position of defects by correlating defect signals from the defect detector with output signals from the scanning detector.
