Title: **Innovations by Ayumu Takakuwa in Cathode Ray Tube Technology**

Introduction

Ayumu Takakuwa, an accomplished inventor hailing from Hyogo-ken, Japan, has made significant strides in the field of cathode ray tube technology. With a total of two patents to his name, Takakuwa has contributed innovative manufacturing methods that enhance the performance and reliability of these crucial components in display technology.

Latest Patents

Among his latest patents, Takakuwa has developed a "Shadow mask assembly manufacturing method" and a "cathode ray tube manufacturing method." The shadow mask assembly manufacturing method involves fastening a shadow mask to a support frame under a precise tension. This process includes applying a preliminary tension force ranging from 9.8 to 490 N at the four corners of the shadow mask in an outwardly slanted manner relative to its sides, followed by applying a main tension force to opposite sides perpendicularly. The outcome is a securely fastened shadow mask that ensures optimal performance in cathode ray tubes.

The cathode ray tube manufacturing method, on the other hand, consists of a pair of supports arranged in parallel and a shadow mask that acts as a color selection electrode with numerous apertures. Takakuwa's invention includes a unique feature where the widths of the apertures narrow gradually from the center towards both end portions, allowing the shadow mask to be uniformly shaped and stretched. This innovation significantly reduces color unevenness in the final product.
