Title: **Innovations of Yoshikazu Demi**
Introduction
Yoshikazu Demi, an accomplished inventor from Shiga, Japan, has made significant contributions to the field of electronic technology. With a remarkable track record of 10 patents, Demi's work primarily focuses on improving cathode ray tube technology. His innovative designs have impacted the performance and quality of visual displays.
Latest Patents
Among Yoshikazu Demi's noteworthy patents is a cathode ray tube featuring a slit in the dead space of the shadow mask. This innovative design effectively prevents the incorrect hitting of color electron beams caused by the local doming phenomenon, thus addressing issues related to color displacement, uneven color distribution, and luminance deterioration. The cathode ray tube incorporates a shadow mask that contains an effective area with aperture lines for electron beams, along with a dead space on either side of this area. The introduction of a slit along the lines of the apertures reduces thermal expansion in the dead space during temperature increases, suppressing stress on adjacent apertures and consequently preventing local doming phenomena.
Another significant invention by Demi is a color cathode-ray tube equipped with a shadow mask that has an attached vibration attenuator. This vibration attenuator operates in a manner that allows it to be movable without adhering to the shadow mask. By utilizing depressions to secure its foot portions through holes in the shadow mask and folding them, the attenuator takes on an approximately rectangular shape. This design effectively absorbs vibration energy through friction, thereby diminishing the vibrations of the shadow mask with a relatively simple mechanism.
