Title: Hiromi Wakasono: Innovator in Cathode Ray Tube Technology
Introduction
Hiromi Wakasono is a prominent inventor based in Hyogo, Japan. She has made significant contributions to the field of cathode ray tube technology, holding a total of 9 patents. Her innovative designs have paved the way for advancements in display technology.
Latest Patents
One of her latest patents involves a color cathode ray tube that features a shadow mask and an inner magnetic shield supported by a mask frame. This design includes an electron shield that has a smaller anhysteretic magnetic permeability than the shadow mask, mask frame, and inner magnetic shield when an applied magnetic field is 800 A/m (10 Oe). This configuration effectively reduces the leakage magnetic field from the tube-axis-side edge of the electron shield, minimizing mis-landing due to terrestrial magnetism and eliminating color displacement.
Another notable patent describes a cathode ray tube that consists of a bulb with a front panel and a funnel, along with an electron gun. The front panel incorporates a color selection mechanism and phosphors on its inner surface. The funnel features a conductive layer on its inner wall, which is divided into at least two regions with different electric potentials. This arrangement allows for stable voltage maintenance and the formation of an electrostatic lens, preventing interference between the conductive layers.
