His innovative approach has led to the development of a unique liquid level indicator that enhances measurement accuracy.
Latest Patents
Astushi Kurosawa holds a patent for a liquid level indicator designed for extremely low temperature-liquefied gas. This invention involves a superconductor wire immersed in the liquefied gas, where a current is passed through it. The voltage across the terminals of the superconductor wire is measured to gauge the liquid level. The improvement in this design includes a current supply portion that first increases the current to the plateau region of the current-voltage hysteresis curve and then decreases it to a return-path rectilinear region. This method allows for precise measurement of liquid levels, such as helium, from the normal-pressure state to the superfluid state.
