Latest Patents

One of Sone's latest patents is a color cathode-ray tube apparatus that includes a video signal generator, a delay circuit, an electron gun assembly, a deflection yoke, a shadow mask, and a phosphor screen. The signal generator is designed to generate three video signals simultaneously. The delay circuit plays a crucial role by delaying the first and second video signals in relation to the third video signal. The phosphor screen features phosphor elements that are regularly arranged. The electron gun assembly is responsible for generating three electron beams at different times, responding to the three signals output by the delay means. These beams are directed towards the phosphor screen, where the phosphor elements emit red, green, and blue light. The overlapping of the three electron beams creates color pixels on the screen. Additionally, the shadow mask, positioned between the phosphor screen and the gun assembly, ensures that the beams land at the desired positions on the phosphor screen. The deflection yoke is utilized to deflect the beams in both horizontal and vertical directions, allowing the electron beams to scan the entire screen effectively.
