Title: Noboru Kawai: Innovator in Optoelectronic and Toner Density Sensor Technologies
Introduction
Noboru Kawai, an esteemed inventor based in Nabari, Japan, is noted for his contributions to optoelectronic technologies and innovative sensor devices. With a total of three patents to his name, Kawai has made significant advancements in the fields of air quality monitoring and toner density sensing.
Latest Patents
Kawai's most recent patent, the Optoelectronic Dust Sensor, outlines a sophisticated mechanism for detecting dust and smoke particles. This system features opening(s) formed at the front panels of the main body housing(s) and passage hole(s) located at the back panels. Between these elements is a dust passage route that facilitates the introduction and discharge of particles. The design ensures that the openings are significantly larger than the passage holes, optimizing airflow and detection efficiency.
Another groundbreaking invention is the Toner Density Sensor, which is designed to achieve high accuracy in detecting toner density while minimizing the impact of temperature fluctuations. Utilizing a light-emitting diode, this sensor emits infrared light toward toner on the surface of a photosensitive drum. The reflected light is then captured by a photodiode, with two amplifier circuits that accommodate both black and color toner densities. Each circuit employs a thermistor for feedback resistance, adjusting gain to yield optimal output.
