Title: Innovations of Toshitaka Suzuki
Introduction
Toshitaka Suzuki is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of sensor technology, particularly in the development of oxygen sensors and air-fuel ratio detectors. With a total of three patents to his name, Suzuki's work has had a considerable impact on automotive and environmental applications.
Latest Patents
One of his latest patents is an innovative oxygen sensor. This device features an airtight reference chamber that is isolated from the surrounding space. A current is supplied to a solid electrolyte, which pumps out oxygen from the reference chamber, ionizing it as it passes through the solid electrolyte. The sensor also includes a mechanism for transferring oxygen from the surrounding space to the reference chamber, allowing for the detection of oxygen concentration based on the current supplied to the solid electrolyte.
Another significant patent is the air-fuel ratio detector. This invention detects the air-fuel ratio in the lean range by measuring a limiting current when oxygen diffuses to a first electrode and is pumped to a second electrode via a solid electrolyte. The stoichiometric air-fuel ratio is determined from the electromotive force between the first and third electrodes. The invention is characterized by its use of three electrodes, enhancing its accuracy. Additionally, the detector can identify a rich air-fuel ratio by measuring currents under specific conditions, showcasing its versatility.
