Latest Patents
Hasegawa's latest patents include a unique heat pipe design. This heat pipe comprises a container that encloses water as a working fluid, made from a material that reacts with water to produce hydrogen gas. The innovation lies in the fact that the container contains a solid oxidizing agent that oxidizes the hydrogen gas back to water, preventing it from remaining in gas form within the condensing portion of the pipe. Another significant patent involves a process for preparing colored aluminum powder. This process entails immersing finely divided aluminum in a weak alkali solution, which is maintained at a temperature between 50 degrees Celsius and the boiling point of the solution. The solution contains a metal salt and at least one aliphatic amine that has chelating abilities, resulting in a composite film of hydrated aluminum oxide and hydrated metal oxide.
