Title: Innovations of Yuichi Yamamoto
Introduction
Yuichi Yamamoto is a notable inventor based in Tochigi, Japan. He has made significant contributions to the field of displacement sensors, holding a total of 4 patents. His work focuses on enhancing the accuracy and reliability of measurement devices.
Latest Patents
One of his latest patents is a displacement sensor that utilizes a plurality of Hall ICs, which are strategically positioned around a magnetic rod that moves along a central axis. The Hall ICs are arranged in various positions concerning both a straight line distance coordinate and a rotational angle coordinate. This innovative design allows for the calculation of the magnetic rod's displacement based on the average output signals from the Hall ICs. Additionally, errors in the output signals caused by shifts and tilts of the magnetic rod are detected, enabling calibration of the measurement method.
Another significant patent is a displacement amount measuring device that addresses errors in measured values caused by changes over time in the characteristics of a displacement sensor. This device ensures high measurement accuracy by acquiring output signals from the displacement sensor when a hydraulic valve, to which the sensor is mounted, is positioned at predetermined locations. The acquired sample values are used to compute a trend of changes over time in the sensor's characteristics, allowing for corrections in the conversion table settings used for displacement amount computation.
