Title: Kazufumi Obara: Innovator in Gas and Electric Regulation Technologies

Introduction

Kazufumi Obara is a notable inventor based in Tokyo, Japan. He has made significant contributions to the fields of gas sensing and electric regulation technologies. With a total of 3 patents to his name, Obara's work reflects a commitment to innovation and practical applications in engineering.

Latest Patents

One of his latest inventions is a gas rate sensor. This device features a holder assembly with a metallic holding portion designed to hold flow sensors. It includes a cylindrical casing that contains the holder assembly and heater wires wound around its exterior. The outer periphery of the holding portion is equipped with multiple projections that compressively contact the inner periphery of the casing, allowing for secure placement of the holder assembly. Additionally, a temperature detection element is positioned in the gas flow passage between the holder assembly and the casing to control the energizing of the heater wires.

Another significant invention is an electric regulator unit. In this unit, a variable electric component is housed within a recess formed in one axial end face of a holder. This design prevents angular movement relative to the axis of the operating shaft. The assembly of the holder and the variable electric component is also accommodated in a recess in a knob, allowing for smooth manipulation. The arrangement ensures that when the knob is turned, the operating shaft moves angularly about its axis. Friction-torque imparting elements are included to provide resistance to the angular movement of the knob.
