Introduction

Nobukazu Ito is a prominent inventor based in Matsudo, Japan. He has made significant contributions to the field of exposure technology, particularly in the development of advanced imaging systems. With a total of 3 patents, his work has had a substantial impact on the industry.

Latest Patents

Nobukazu Ito's latest patents include an exposure apparatus and exposure method, as well as a device and method for producing vibration isolators. The vibration isolators support a main column mounted on a base plate, while also independently supporting a stage on another base plate arranged on the floor. This innovative design effectively cuts off vibration traveling between the base plates, preventing reaction forces from affecting the projection optical system. As a result, the exposure accuracy is significantly improved, allowing for increased speed and size of the substrate stage, thereby enhancing throughput.

Another notable patent is an image reading device and method. This system prescans and scans a film with magnetic recording, storing image data in a film cartridge after development. Utilizing a one-dimensional CCD, the system can record and read retrievable ID numbers on a magnetic recording part. A thumbnail display allows for simultaneous viewing of all image and magnetic information, making it easier to identify and compare selected frames after obtaining image data.
