Latest Patents
One of Gyu-nam Ju's latest patents involves a cathode for an electron tube that features a layer of an electron-emitting substance. This substance contains alkaline earth metal oxides with 0.01-20.0 wt % of both a lanthanum compound and a magnesium compound or a lanthanum-magnesium compound. This layer is applied to a base metal primarily composed of nickel and secondarily of tungsten. The inclusion of tungsten prevents embrittlement and ensures a continuous supply of barium in the electron-emitting substance. This cathode offers full interchangeability with conventional oxide cathodes and boasts a lifespan that is 15-30% longer.
Another notable patent by Ju describes a cathode for an electron tube that incorporates a layer of electron-emissive substance made from alkaline earth metal carbonates with capillary crystals. Similar to his previous invention, this cathode also includes 0.01-20.0 wt % of both a lanthanum compound and a magnesium compound or an La-Mg compound. This design allows for full interchangeability with conventional oxide cathodes and extends the lifetime by 15-20%.
