Title: Innovations of Vincent Y Kotsubo
Introduction
Vincent Y Kotsubo is a notable inventor based in La Canada, California. He has made significant contributions to the field of cryogenics, particularly with his innovative refrigeration technology. His work focuses on utilizing superfluid helium to achieve ultra-low temperatures.
Latest Patents
Kotsubo holds a patent for a "Superfluid Thermodynamic Cycle Refrigerator." This invention involves a cryogenic refrigerator that cools a heat source by cyclically concentrating and diluting the amount of helium-3 in a single-phase helium-3 and helium-4 solution. The helium-3 in superfluid helium-4 behaves like an ideal gas in a vacuum, allowing for refrigeration through conventional thermal cycles, preferably using a Stirling or Carnot cycle. The design includes a first variable volume connected to a second variable volume through a superleak device, which permits the free passage of helium-4 while restricting helium-3. This phased compression and expansion of helium-3 enables effective heat removal for cooling below 1 K.
