Title: Hirosumi Itoh: Innovator in Pattern-Matching Technology
Introduction
Hirosumi Itoh is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of sewing technology, particularly in pattern matching. With a total of 6 patents to his name, Itoh has developed innovative solutions that enhance the efficiency and accuracy of sewing processes.
Latest Patents
One of his latest inventions is the pattern matching sewing machine. This machine features a sewing means for joining two superposed sheets of cloth that have substantially identical patterns. It includes a feeding means to guide the cloth sheets into the sewing mechanism, a detecting means to identify any mismatch distance between the patterns, and a transport means to move the sheets relative to each other. The machine is designed to minimize the pattern displacement amount detected by the mismatch distance. Additionally, a determining means assesses whether pattern matching is feasible based on the mismatch distance data obtained.
Another significant invention is the pattern-matching sheet-joining machine. This machine is designed to join two sheets, such as sewing two cloths, ensuring that the patterns align perfectly. It utilizes a pattern-sensing photo-sensor that generates intensity data for three different colors. The color data is processed to accurately discriminate elements of a pattern, even when colors have similar brightness. The machine can calculate differences between intensity data for various colors or select the color with the most significant intensity change.
