Title: Yoshi Ishizuka: Innovator in Encoder Technology
Introduction
Yoshi Ishizuka is a prominent inventor based in Nagano, Japan. He has made significant contributions to the field of encoder technology, holding a total of 6 patents. His innovative designs focus on enhancing detection accuracy while reducing device costs.
Latest Patents
One of his latest patents involves an encoder designed to achieve highly reliable detection accuracy. This encoder features a light detection unit that receives light from a light source, which is transmitted through light-transmitting portions of Gray code optical patterns on a rotating disk. The light detection unit then converts this light into digital data. Additionally, a magnetic detection unit captures the magnetic pattern of a magnet located at the rotation center of the disk, also converting it into digital data. A processing unit then compares the data from both detection units to correct any detection errors.
Another notable patent is for an optical encoder device that includes a movable slit plate and a stationary slit plate. This design allows for an increased number of light transmissive slits on the stationary plate, optimizing the output signal and minimizing distortion. The movable slit plate is equipped with a slit row that alternates between light transmissive and non-transmissive slits, enhancing the encoder's performance.
