Introduction

Sakaguchi Masaaki, an accomplished inventor based in Kanagawa, Japan, has made significant contributions to the field of tape defect detection. With a total of two patents to his name, he focuses on innovative methods that enhance the quality and reliability of tape products.

Latest Patents

Masaaki's latest patents demonstrate his expertise and creativity in addressing tape-related issues. One of his prominent inventions is a method for detecting tape defects. This technique employs a light amount signal obtained from the surface of a tape, which is scanned with a light beam that extends beyond the edges of the tape. The light signal is differentiated to create a light amount differential signal. If this signal deviates from a predetermined reference level, or if a change occurs at a different point in time than expected, the method successfully identifies a defect near the tape edge.

Another notable patent is a joint inspection apparatus designed to determine the size of a gap at the joint of two tape edge portions. This device includes a light irradiating system that directs light toward the tape joint, as well as a light receiving device that captures light either passing through or reflecting off the joint. A judgment device processes information from the light receiving device to accurately assess the gap size between the tape edges.
