Title: The Innovative Contributions of Do-Nyun Kim
Introduction
Do-Nyun Kim is a prominent inventor based in Kyungki-do, South Korea. He has made significant contributions to the field of cathode ray tube technology, holding a total of 8 patents. His work has focused on improving the efficiency and effectiveness of electronic display devices.
Latest Patents
Among his latest patents is the "Deflection Yoke for Cathode Ray Tube." This invention enhances assembly and productivity while enabling effective control of magnetic field corrections during device processing. The deflection yoke features a horizontal deflection coil positioned next to the outer circumference of a funnel to generate a horizontal magnetic field. Additionally, a vertical deflection coil is installed at the outer circumference of the funnel to create a vertical deflection magnetic field. The vertical deflection coil is insulated from the horizontal deflection coil, and a ferrite core is strategically placed to reduce magnetic force loss and enhance efficiency. Furthermore, a correction unit is spaced apart from the horizontal deflection coil to correct geometric distortions in the magnetic fields.
Another notable patent is the "Funnel for Cathode Ray Tube." This invention includes a body portion with an opened end connected to a panel and an alignment mark on the outer surface near the opened end. The funnel also features a neck portion for housing an electron gun and a yoke portion for mounting the deflection yoke. A convex portion with a thickness greater than 1 mm is provided on the outer portion of the body and/or yoke portion, extending from the alignment mark to the top-of-round (TOR) in the direction of the tube axis.
