Latest Patents
Iwabayashi's latest patents focus on advancements in discharge lamp technology. One of his inventions includes a discharge lamp that features an emitter other than thorium, which is added to a cathode in a luminous tube. This design prevents early depletion of the emitter due to excessive vaporization, ensuring stable lighting even during start-up. The main body part of the cathode is constructed from a high-melting-point metal material that contains no thorium, while the front end part is made from a similar material that includes an emitter other than thorium. Additionally, a sintered compact containing a higher concentration of the emitter is strategically placed within a sealed space in the main body and/or front end part, enhancing the lamp's performance.
Another patent by Iwabayashi also revolves around a discharge lamp that incorporates a cathode in a luminous tube. This design similarly prevents excessive vaporization of the emitter from the cathode, allowing for smooth lighting during start-up. The main body part of the cathode is made from a high-melting-point metallic material without thorium, while the front end part contains an emitter. A sintered compact with a higher concentration of the emitter is again utilized within a sealed space, further improving the lamp's efficiency.
