Title: Tomohito Yamazaki: Innovator in Absolute Encoder Technology

Introduction

Tomohito Yamazaki is a notable inventor based in Nagano, Japan. He has made significant contributions to the field of absolute encoder technology, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

Yamazaki's latest patents include the "Batterless Absolute Encoder" and the "Magnetic Absolute Encoder." The Batterless Absolute Encoder is designed to determine the accuracy of absolute position information when electric power is turned on. It features an alarm signal output in case of abnormalities. This encoder includes an absolute position computing section, an absolute position storing section, and a determining section. The computing section calculates the absolute position of a spindle based on detection signals from four reluctance resolvers. The storing section retains the absolute position when power is off, while the determining section compares the current and stored positions, triggering an alarm if discrepancies exceed a predetermined threshold.

The Magnetic Absolute Encoder enhances resolution through a sophisticated cycle determining process. It utilizes data stored in a fourth angle data storing section to ascertain the cycle of newly computed fifth angle data in response to the rotation of a rotary shaft. This encoder employs multiple cycle determining sections to accurately establish the absolute position based on the current first angle data.
