Title: Seiji Toda: Innovator in Position Sensing and Distance Measurement Technologies

Introduction

Seiji Toda is a notable inventor based in Nagaokakyo, Japan. He has made significant contributions to the fields of position sensing and distance measurement. With a total of two patents to his name, his work reflects a commitment to advancing technology in these areas.

Latest Patents

Seiji Toda's latest patents include a position sensor and a distance measuring apparatus. The position sensor features a coil and an electric conductor or magnetic element arranged to vary the overlapping area as the position of an object changes. This design incorporates a resistor, a capacitor, a comparator of an inverse output type, and a timing circuit to detect displacement as a change in time duration. The resistance of the resistor is optimized to maintain minimal change in time duration under varying temperatures, thereby improving output linearity.

The distance measuring apparatus operates by introducing a high-frequency pulse at one end of a parallel conductor. An impedance mismatch generator is placed in the conductor's intermediate region, producing a reflected wave of the pulse. The duration before the reflected wave is received is measured and multiplied by the propagation speed of voltage to calculate the distance from the pulse introduction point to the impedance mismatch generator.
