Title: Akitsuna Yuhara: Innovator in Communication Technology

Introduction

Akitsuna Yuhara is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of communication technology, holding a total of 18 patents. His innovative work focuses on improving communication systems and display technologies.

Latest Patents

Yuhara's latest patents include a spread spectrum communication device and a communication system. This invention addresses issues with conventional spectrum spreading communication using Barker codes. It limits the rise of the side-lobe of a correctional signal independently of the order of information codes by utilizing a code sequence with a length of at least 14. The device employs a pseudo-noise code with a length of at least 14 and a self-correlation side-lobe of not greater than 3. This advancement allows for better handling of digital information and reduces the error rate of the communication device while improving processing gain.

Another notable patent is for a discharge type display apparatus that utilizes a mixture of three gases. This apparatus displays images through discharges in a gas enclosed within discharge spaces. The discharge gas consists of a mixed gas including at least xenon (Xe), helium (He), and neon (Ne), with a mixed ratio of helium to neon set to approximately 50% in volume at most.
