Title: Yasuo Sawamura: Innovator in Absolute-Value Encoder Technology
Introduction
Yasuo Sawamura is a notable inventor based in Nagano, Japan. He has made significant contributions to the field of encoder technology, particularly in the development of multiple-rotation absolute-value encoders. With a total of three patents to his name, Sawamura's work has had a considerable impact on the efficiency and precision of geared motors.
Latest Patents
One of Sawamura's latest patents is the "Multiple-rotation absolute-value encoder of geared motor." This invention involves a geared motor that reduces the rotational speed of a motor shaft and drives a machine device within an operating range corresponding to two rotations of the gear shaft. The encoder is designed to detect the absolute position of the gear shaft and includes a load side absolute value encoder that operates at a reduced rotational speed.
Another significant patent is the "Method for magnetizing ring magnet and magnetic encoder." This method involves fitting an insert member with identical permeability into the circular center hole of a magnetic ring. The magnetic ring is then placed in a parallel magnetic field, allowing for linear magnetic flux lines. This innovation minimizes harmonic noise, which can deteriorate detection precision in magnetic sensors, thereby enhancing the performance of magnetic encoders.
