Title: Akihisa Inoue - Innovator in Liquid Helium Measurement
Introduction
Akihisa Inoue is a notable inventor based in Kawauchi, Japan. He has made significant contributions to the field of measurement technology, particularly in the area of liquid helium. His innovative approach has led to the development of a unique level gauge that utilizes superconductive materials.
Latest Patents
Inoue holds a patent for a level gauge designed specifically for liquid helium. This invention features a sensing element made of a ribbon wire composed of superconductive alloys. The gauge includes a tube that supports the sensing element, which is immersed in liquid helium during measurement. The superconductive alloys are defined by the formula Zr.sub.100-x.(Ru.sub.y.Rh.sub.1-y).sub.x, where x indicates the atomic percentage of Ru and/or Rh, ranging from 22.5 to 27.5, and y varies from 0 to 1. The alloys are produced in an amorphous phase through rapid quenching of molten alloy material, achieving a superconducting transition temperature, Tc, between 4.2 K and 4.5 K. When the gauge is submerged in liquid helium, the portion of the sensing element below the liquid level exhibits zero electric resistance due to the superconductivity of the alloy. This allows for the detection of the liquid helium level through variations in the resistance of the sensing element. Inoue's patent is a testament to his innovative spirit and technical expertise, with a total of 1 patent.
