Title: Innovations of Masana Minami: A Pioneer in High-Precision Encoders

Introduction

Masana Minami, an accomplished inventor based in Kawasaki, Japan, has made significant contributions to the field of high-precision measurement devices. With a record of nine patents, her innovations are pivotal in enhancing the accuracy of various measuring instruments.

Latest Patents

One of her most recent patents showcases an advanced encoder designed for length or angle measuring devices. This encoder features a code plate with binary grating patterns organized in a specific regular pattern, which forms the first scale. It incorporates a linear sensor with photodiode elements configured at fixed intervals, creating a parallel second scale to the code plate. The innovative processor means developed by Minami performs absolute interpolation based on reading data from the linear sensor, effectively determining the relative position of the patterns to the sensor elements. This design includes a system where when the first scale contains N divisions, the second scale features N+1 divisions. Thus, when the first scale acts as a main scale, the second serves as a vernier scale. The processor adeptly identifies phase inverting points, enabling precise absolute interpolation.

Another notable patent involves an encoder with an optical measuring component that establishes a vernier relationship between the code plate and a linear sensor. This encoder utilizes counters to derive a course reading from the time-serial output signals of the linear sensor, alongside a fine reading derived from the vernier relationship. Minami's invention further integrates correction data that accounts for changes in the magnification of the lens system, ultimately providing a corrected fine reading.
