Title: **Yoshihisa Nakajima: Innovator in High Voltage Treatment for Cathode Ray Tubes**
Introduction
Yoshihisa Nakajima is an accomplished inventor based in Nagaokakyo, Japan. With a unique focus on innovations in high voltage treatment technology for cathode ray tubes, he holds two significant patents that enhance the functionality and safety of these devices.
Latest Patents
Nakajima's latest innovations include two essential patents. The first patent describes an *Apparatus for high voltage treatment of cathode ray tube*. This invention features a neck that has one end closed with a stem, which houses an electron gun along with stem pins for a focus electrode and other electrodes. It aims to create a high-pressure gas atmosphere around the neck while maintaining a voltage significantly higher than the cathode ray tube's operating voltage. To prevent creeping discharge, the neck’s temperature is carefully regulated above that of the high-pressure gas atmosphere during voltage application. An alternative method outlines setting the dew point of the gas atmosphere at a maximum of 25°C.
His second patent, titled *Method and apparatus for high voltage treatment of cathode ray tube*, mirrors the first in principle and application. It describes a similar configuration utilizing the high pressure gas atmosphere and specific voltage management strategies to optimize cathode ray tube performance and safety.
