Title: Innovations of Hiroshi Atarashi
Introduction
Hiroshi Atarashi is a notable inventor based in Kashihara, Japan. He has made significant contributions to the field of satellite broadcasting technology, holding three patents to his name. His work focuses on enhancing the efficiency and functionality of satellite communication systems.
Latest Patents
Atarashi's latest patents include a low-noise block down-converter and a satellite broadcasting receiving apparatus. The low-noise block down-converter features frequency converting circuits that correspond to individual satellites. These circuits convert frequency bands of two types of polarization signals received from the corresponding satellite into two intermediate frequency bands that do not overlap. Additionally, signal couplers perform frequency-multiplexing of the two types of polarization signals to generate a first combined signal. A signal rearranging circuit selects any two first combined signals, allowing duplicate selection, and extracts one polarization signal from each selected signal to create a second combined signal.
His satellite broadcast receiver apparatus is designed to reduce power consumption. This apparatus includes multiple signal conversion units corresponding to signals transmitted from one or more satellites. Each unit frequency-converts a corresponding signal for output. A signal select circuit transmits a desired signal among the outputs to a signal terminal based on a control signal. The power supply control unit manages voltage supply to the signal conversion units, supplying operating voltage to selected units while suppressing it to the others.
