Latest Patents
Ichinose holds a patent for a "Method for producing a fused silica envelope for discharge lamp." This method involves coating the inner surface of a fused silica tube with a formulation containing titanium alcoholate. The coating undergoes a baking process at a temperature of at least 1720°C, allowing TiO₂ to diffuse into the tube. The resulting titanium concentration ranges from 0.5% to 7% in terms of TiO₂, with an overall average Ti concentration and wall thickness ranging from 3.7% μm to 42% μm. The method also includes shaping the tube into a bulb-like portion by inflating the silica tube during the baking step.
