Title: The Innovations of Shinichi Ohmagari
Introduction
Shinichi Ohmagari is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of telecommunications, particularly in radio station apparatus and signal transmission methods. With a total of 7 patents to his name, Ohmagari continues to push the boundaries of innovation in his industry.
Latest Patents
One of his latest patents is a radio station apparatus and signal transmission method. This invention provides a radio station apparatus that converts multiple input digital transmission signals with varying data transmission rates into an analog signal. The apparatus modulates the analog signal with a radio carrier frequency and transmits the modulated signal. The design includes an indoor unit, outdoor unit, and coaxial cable that connects the two. The first binary digital signal is converted into a serial second binary digital signal by a parallel/serial converter and modulated by amplitude shift keying (ASK). The multiplexed signal is then transferred to the outdoor unit, where it is demultiplexed and converted back into an analog signal.
Another notable patent is a transmitter featuring an envelope feedback loop and automatic level control. This invention aims to provide a compact and cost-effective transmitter that minimizes power dissipation. The design includes a phase modulator, variable attenuator, high power amplifier, and other components that form an envelope feedback loop. This loop controls the envelope of a modulated wave to ensure that the baseband signal aligns with the modulated wave.
