Latest Patents

One of his latest patents is a displacement detection device that promotes miniaturization. This device includes a coil and a magnetism-responsive member that displaces relative to the coil based on the position of a detection object. It features a self-oscillation circuit that incorporates the coil as an oscillation element, allowing the oscillation frequency to vary with inductance changes due to displacement. An arithmetic section generates measured values based on the oscillation frequency, calculates velocity data, and integrates it to determine displacement data. This design effectively cancels or reduces offset error components caused by temperature or mechanical attachment positions, enabling precise displacement detection.

Another notable patent is a phase difference detection device and method for a position detector. This invention involves receiving two A.C. output signals that are amplitude-modulated according to sine and cosine function values. By shifting the electric phase of one signal and synthesizing it with the other, the device can accurately detect phase differences corresponding to the position being measured. This method allows for the cancellation of phase variation errors, ensuring accurate phase difference detection.
