Title: Masaki Nakahara: Innovator in Cathode-Ray Tube Technology
Introduction
Masaki Nakahara is a notable inventor based in Chigasaki, Japan. He has made significant contributions to the field of cathode-ray tube technology, holding a total of 4 patents. His work has been instrumental in advancing the functionality and efficiency of electronic displays.
Latest Patents
Nakahara's latest patents include a deflection system designed for cathode-ray tubes. This system features a horizontal deflection core, a magnetic coil, and a vertical deflection coil that is toroidally wound on the magnetic core. The vertical deflection coil is uniquely structured with multiple superimposed winding layers, which are arranged concerning the vertical axis of the deflection system. This innovative design helps to prevent ringing by ensuring that the induced voltage in the layers is substantially equal in the region of the vertical axis.
Another significant patent is his convergence system, which generates magnetic fields to converge multiple electron beams in a cathode-ray tube. This system includes a convergence yoke with a core that has a ring-shaped outer periphery and magnetic poles extending toward the neck part of the cathode-ray tube. The system is equipped with a lateral line comma aberration correcting coil arrangement and a longitudinal line correction coil arrangement, both of which are essential for correcting misconvergence on the fluorescent face of the cathode-ray tube.
