Latest Patents

Aihara's latest patents include innovative methods related to cathode-ray tubes. One of his patents focuses on a cathode-ray tube fluorescent material and its method of manufacture. This invention involves attaching electrolytes to the surfaces of fluorescent particles to prevent open spots in cathode-ray tube coatings that are dried at high temperatures. The electrolytes, which can be sulfates, nitrates, or chlorides of alkali or alkaline-earth metals, are added to a liquid suspension of fluorescent particles that have undergone a cleaning step. The process ensures that the conductivity of the clear top liquid exceeds 30 μ.Ω.sup.-1 cm.sup.-1. The preparation of the fluorescent particles is completed with a final dehydration and drying step.

Another significant patent by Aihara is a method of reclaiming phosphor from a recovered phosphor slurry containing carbon, bichromate, and polyvinyl alcohol. This method includes several steps: a decomposition treatment where an alkali is added to the heated slurry, a weak acid treatment to separate the phosphor, and a surface treatment step to enhance the phosphor's properties.
