Title: Hirokatsu Ohbayashi: Innovator in Lens Grinding Technology
Introduction
Hirokatsu Ohbayashi is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of lens grinding technology, holding a total of 2 patents. His innovative approaches have enhanced the efficiency and precision of lens manufacturing processes.
Latest Patents
Ohbayashi's latest patents include a "Lens grinding apparatus having chamfering and other grinding wheels." This invention features a subject lens held by two chuck shafts, which are rotated synchronously by pulse motors during the grinding operation. The apparatus is equipped with chamfering and other grinding wheels mounted on a rotary shaft of a lens grinding part. A desired grinding wheel for each processing is selected by moving the rotary shaft vertically. For rough processing, the rotary shaft is moved toward the center of the chuck shafts based on lens frame shape data. In the case of chamfering, the rotary shaft is adjusted both vertically and horizontally based on chamfering data, which is produced by a lens measuring section that measures the shapes of the front and rear surfaces of the subject lens.
Another significant patent is the "Lens grinding apparatus for grinding an eyeglass lens from a plurality." In this invention, a subject lens is similarly held by two chuck shafts, which are rotated synchronously by pulse motors. A group of grinding wheels is mounted on each of the rotary shafts of the right and left lens grinding parts. The rotary shafts are positioned on opposite sides of the chuck shafts, allowing for independent movement toward the rotation axis of the chuck shafts based on lens frame shape data during rough processing.
