Latest Patents

One of Takehara's latest patents is a device for forming amorphous film and the method for forming the same. The problem addressed by this invention is the need for a large device and method that is advantageous for forming large-area amorphous films. The solution involves a device that sprays a flame containing a particulate material toward a substrate, melting the material with the flame. The material and flame are then cooled by a cooling gas before reaching the substrate, resulting in the formation of an amorphous film. The spraying machine is designed with particulate material spraying ports and flame spraying ports, creating an oblong cross-section for the flame and material. Additionally, inert gas spraying ports and mist spraying ports are strategically placed to enhance the process. A skirt is also included to control film width and thickness deviation.

Another notable patent by Takehara is for a separator material for polymer electrolyte fuel cells. This invention boasts excellent corrosion resistance, conductivity, and formability. The manufacturing method involves preparing a thin plate using an ultraquenching transition control injector with a mixture of corrosion-resistant metal powder and conductive powder. Depending on the matrix structure, the plate can be formed at room temperature or in a supercooled liquid state, allowing for the creation of separators with intended shapes.
