Title: The Innovations of Hiroshi Kubota: Pioneering Sensor Technology

Introduction

Hiroshi Kubota, an accomplished inventor based in Wako, Japan, has made significant contributions to the field of sensor technology. With a portfolio of six patents, his innovative work focuses on enhancing the performance and reliability of gas sensors, particularly in automotive applications.

Latest Patents

Hiroshi's most recent inventions include a "Sensor Deterioration Judging Apparatus" and a corresponding "Sensor Deterioration Judging Method." These advancements involve a sophisticated gas sensor controller that can effectively determine the operational state of a pumping cell based on oxygen concentration levels. The controller pauses pumping operations when the gas concentration meets a specific threshold and calculates oxygen pressure in a secondary chamber using pump currents. By comparing this pressure against established deterioration judgment values, the controller can accurately classify the condition of the pump cell as either normal or deteriorated.

Another significant aspect of his latest patents includes a detailed sensor diagnosis process. This method involves controlling an NOx gas sensor to alter oxygen partial pressure within a measurement chamber, enabling precise detection of pump cell performance. The ratio of current values detected before and after pressure changes informs the controller if the pump cell is functioning effectively.
