Title: Yujiro Naruse: Innovator in Acoustoelectric Devices
Introduction
Yujiro Naruse is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of acoustoelectric devices, holding a total of 9 patents. His innovative work has paved the way for advancements in sensor technology and signal processing.
Latest Patents
One of Naruse's latest patents is an acoustoelectric conversion device. In this device, a light wave from a light source is introduced into a first optical waveguide of a vibration substrate. The light is diffracted by a diffraction grating disposed on the first optical waveguide. The diffracted light is then directed to and detected by a photo detector. The vibration substrate is supported to vibrate with respect to an acoustic wave, allowing the detected diffracted light to be modulated by the acoustic wave. Consequently, a signal is output from the detector in accordance with the acoustic wave.
Another notable patent is a sensor device that detects physical or chemical change amounts. This device includes a sensor array with infrared sensors and a detection circuit connected to the output signal line of the sensor array. The detection circuit features a capacitor with a selectively driven charging circuit, a sense amplifier circuit for detecting and amplifying changes in sensor current, a current-to-voltage conversion circuit, a discharging circuit controlled by the output voltage, and an output circuit that outputs the terminal voltage of the capacitor.
