Title: Mitsuhiko Inaguma: Innovating the CATV System with Patented Inventions
Introduction:
Mitsuhiko Inaguma is an inventive mind hailing from Nisshin, Japan, who has made significant contributions to the field of CATV systems. With an impressive track record of three patents, Inaguma's expertise lies in the development of in-building CATV systems and their associated components.
Latest Patents:
Inaguma's recent patents focus on improving frequency conversion within CATV systems, specifically in-building CATV systems that utilize up-converters, down-converters, and amplifiers. His inventions aim at achieving accurate frequency conversion without the need for an external pilot signal.
The first patent encompasses an innovative down-converter equipped with a reference oscillation circuit that generates a reference signal with a frequency lower than that of the downward or in-building upward signal. This reference signal is then utilized to frequency-convert the in-building upward signal while also being transmitted to the terminal side's transmission line. This approach allows for accurate frequency conversion and efficient signal transmission through a bi-directional amplifier.
The second patent focuses on the interplay between up-converters and down-converters within in-building CATV systems. In order to ensure precise restoration of the upward signal, the down-converter utilizes a frequency division circuit to convert the converting reference signal to a transmitting reference signal with a lower frequency. This transmitting reference signal is then outputted to the terminal side, enabling accurate signal restoration.
