Latest Patents

Son's patent, titled "Metal cathode and indirectly heated cathode assembly having the same," presents a transformative approach to electron-emission technology. The patented metal cathode is engineered from a quaternary alloy that includes 0.1-20% by weight of barium (Ba) and a metallic mobilizer to facilitate Ba diffusion. This innovation includes a metal with a specific atomic radius difference from platinum (Pt) or palladium (Pd), positioned between 0.01 to 30% by weight. The result is a metal cathode that operates at low temperatures due to reduced work function, boosting current emission capability and extending lifespan at high current densities. This advancement is especially relevant for electron-beam devices such as Braun tubes or picture tubes, addressing the increasing demand for larger sizes, prolonged lifespans, high definition, and enhanced luminance.
