Title: Takeshi Okada and His Ultrasonic Delay Line Patent.

Introduction

Takeshi Okada is an inventor associated with Yokohama, Japan, and Asahi Glass Company, Limited. His recorded patent work includes an ultrasonic delay line designed to distinguish a main signal from higher-frequency harmonic components. His patent portfolio includes 1 patent.

Latest Patents

Okada’s listed patent, “Ultrasonic Delay Line,” describes a system with an input transducer that converts an input voltage into a sound wave, a delay medium that transmits the wave, and an output transducer that receives it. The delay medium is shaped so that sound waves are directed away from the output transducer by a predetermined amount. This arrangement allows a substantial part of the main signal to reach the output transducer while causing a substantial part of the third and higher harmonics to miss it, taking advantage of the greater directivity of those higher-frequency components.

Career Highlights

The available information associates Okada’s invention with Asahi Glass Company, Limited. The patent’s design addresses signal separation within an ultrasonic delay line by using the propagation characteristics of sound waves at different frequencies.

Collaborations

Haruto Hashimoto and Michihiko Uemura are identified as Okada’s coworkers. The available details do not specify their roles in the patent or the nature of their collaboration.

Conclusion

Takeshi Okada’s recorded invention demonstrates an approach to reducing higher-harmonic interference in ultrasonic delay lines through the deliberate shaping of the sound-wave path.
