Introduction

Yuichi Niimura is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of optical technology, holding a total of six patents. His work focuses on developing advanced optical devices that enhance communication and signal processing.

Latest Patents

One of his latest patents is an optical coupling device. This device includes a primary conductive plate, a light-emitting part, a secondary conductive plate, a light-receiving part, and a first conductive part. The light-emitting part is located on the primary conductive plate, converting an electrical signal to light and emitting it. The secondary conductive plate is spaced apart from the primary conductive plate and faces the light-emitting part. The light-receiving part is disposed on the secondary conductive plate to face the light-emitting part, converting light from the light-emitting part back into an electrical signal. The first conductive part is positioned to concentrate the electric field generated by the potential difference between the primary and secondary conductive plates.

Another notable patent is an optical reception circuit. This circuit includes a first photodetector, a first transimpedance amplifier, a level shift circuit, a second photodetector, a second transimpedance amplifier, a peak hold circuit, and a comparator. The first transimpedance amplifier converts a first light current from the first photodetector into a first voltage. The level shift circuit generates a signal voltage from this first voltage. The second transimpedance amplifier converts the second light current from the second photodetector into a second voltage. The peak hold circuit holds the peak voltage of the second voltage as a first threshold voltage, while the comparator compares the signal voltage with this threshold.
