Title: **Kazuya Toki: Innovator in Radio Technology**

Introduction

Kazuya Toki is a notable inventor based in Sendai, Japan, recognized for his contributions to radio technology. With two registered patents, Toki has made significant advancements that enhance transmission efficiency and reliability in communication systems.

Latest Patents

One of his latest patents is a **Time Division Multiplexing Radio System for Controlling Transmission Power**. This innovative system manages transmission power by utilizing an adjacent-channel leakage power ratio, ensuring precision and stability. It incorporates a directional coupler positioned at the output stage of a power amplifier within the transmitter, with outputs directed to both the antenna and the receiver. During transmission, a reception RF switch toggles to the coupler, allowing the receiver to measure the current channel's transmission power while simultaneously detecting adjacent-channel leakage. The calculated power ratio enables automatic control of the transmission power to meet specified conditions.

Kazuya Toki has also developed a **Narrow Band Radio Transmitting and Receiving Apparatus and Method**. This invention focuses on reducing the starting failure time when initiating transmission. The process starts with a DTMF signal generated at a frequency ranging from 697 Hz to 1633 Hz, transitioning to a DTMF signal at one-tenth frequency after 0.02 seconds. The DTMF receiver at the receiving end adjusts its output mute circuit based on the received signals, thus streamlining the communication process.
