Title: Shigeharu Katou: Innovator in Absolute Encoder Technology

Introduction

Shigeharu Katou 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

One of his latest inventions is the Batterless Absolute Encoder. This device determines the accuracy of absolute position information when electric power is turned on and outputs an alarm signal in case of any abnormalities. The encoder consists of 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 the power is off, while the determining section compares the current and stored positions, triggering an alarm if discrepancies exceed a predetermined threshold.

Another significant invention is the Magnetic Absolute Encoder, which offers enhanced resolution. This encoder features a first cycle determining section that utilizes data from a fourth angle data storing section to ascertain the cycle of newly computed fifth angle data in response to rotary shaft rotation. It also includes a second cycle determining section and a third cycle determining section to accurately determine the absolute position based on the current first angle data.
