Title: Naofumi Furuta: Innovator in Sensor Technology

Introduction

Naofumi Furuta is a notable inventor based in Konan, Japan. He has made significant contributions to the field of sensor technology, holding a total of 5 patents. His work focuses on developing advanced systems for detecting various objects, particularly in the semiconductor and magnetic disk industries.

Latest Patents

Furuta's latest patents include a reflection type sensor and a system for detecting disk-shaped objects such as semiconductor wafers or magnetic disks. The reflection type sensor features a light-emitting element that emits light to an object, utilizing multiple LED chips integrated into a package. These LED chips emit light beams of different wave bands, while a light detecting element captures the reflected light and performs photoelectric conversion. This technology allows for the determination of an object's presence based on the light signal received.

The disk-shaped object detecting system is designed to identify the presence and position of disk-shaped objects. It employs a light-emitting element that directs light toward the circumferential edge of the object. As the light-emitting element moves across the object, a light-receiving element captures the reflected light, delivering first and second light signals. The system processes these signals to determine the object's position accurately.
