Title: Takuma Hattori: Innovator in Electromagnetic Wave Absorption Technology
Introduction
Takuma Hattori is a notable inventor based in Shizuoka, Japan. He has made significant contributions to the field of electromagnetic wave absorption technology, holding a total of 3 patents. His work focuses on developing materials that enhance the performance of electronic devices.
Latest Patents
One of Hattori's latest patents is the matched-type electromagnetic wave absorber. This innovative sheet-shaped absorber achieves high electromagnetic wave absorption performance while maintaining a relatively small thickness. However, it addresses the challenge of dimensional changes in the absorption layer when exposed to high temperatures. By laminating a resin composition layer with fillers of varying aspect ratios and combining it with an electromagnetic wave reflection layer, Hattori has created a product that offers high heat-resistant dimensional stability and superior electromagnetic wave absorption performance.
Another significant invention is the attachment film for electronic display devices. This film is designed to adjust the optical transmissivity and color shades in various electronic displays. It simplifies the adjustment of reflections from fluorescent lamps and sunlight, while also preventing the formation of air bubbles in the adhesive layer. The film consists of a transparent substrate with an adhesive layer containing dispersed carbon black.
