Title: Yuzo Usui: Innovator in Noise Elimination and Communication Technology
Introduction
Yuzo Usui is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the fields of noise elimination and communication technology. With a total of 9 patents to his name, Usui has demonstrated a commitment to innovation and excellence in his work.
Latest Patents
Among his latest patents is a noise elimination method and transmission circuit. This method is characterized by its ability to transmit signals in the same direction on at least two distributed constant lines. A key feature of this invention is the setting of a terminating resistor at the far-end, ensuring that voltages propagated to the far-end are equal between two kinds of propagation modes on coupled distributed constant lines. The two modes include a common mode, which propagates with respect to a ground plane, and a differential mode, which propagates between the coupled lines. Another notable patent is for an IC card-type radio communication device. This device includes a main body of equipment, a storage unit, a sound input unit, a sound output unit, and a modulation-demodulation unit. The main body of equipment is designed to conform to a predetermined standard and is inserted into an entry installed on an external terminal unit. The storage unit stores attribute information and data necessary for communication with the terminal unit, while the sound input and output units facilitate conversation execution.
