Latest Patents

Kojima’s patent, titled "Photoelectric Conversion Type Rotational Position Detector," introduces a sophisticated design for a rotational position indicator. This invention utilizes a light receiving member composed of multiple identically shaped light receiving portions made from a photoelectric converting material. These portions generate sinusoidal signals that are out of phase with one another. The device incorporates a light shielding member that rotates with the body being detected, featuring uniquely shaped windows. As the shielding member turns, it creates a sinusoidal variation in the visible area of each light receiving portion, allowing precise detection of rotational position. The innovation further includes means for obtaining the phased separated sinusoidal signals by connecting groups of light receiving portions in parallel or series.
