Title: Innovations of Yoshikazu Kawashima

Introduction

Yoshikazu Kawashima is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of communication technology, holding a total of four patents. His work focuses on advanced signal processing and power reception technologies.

Latest Patents

One of his latest patents is the "Baseband Signal Communication Apparatus." This invention includes a transmission unit and a reception unit. The transmission unit superposes a subcarrier on one value of a baseband signal consisting of binary values, modulates a carrier with the baseband signal on which the subcarrier is superposed, and transmits the baseband signal as a transmission signal wave. The reception unit demodulates the baseband signal having the subcarrier superposed thereon by using a demodulator upon reception of the transmission signal wave. It extracts the subcarrier from the demodulated signal by using a bandpass filter and demodulates the baseband signal by causing a detector to detect an envelope of the subcarrier.

Another significant patent is the "Microwave Electric Power Receiver." In this invention, a microstrip resonator having a line length of 1/2 of a wavelength of a microwave to be received is notched to be split at its longitudinally central portion into two portions. A rectification diode is interposed between notched end portions of the microstrip resonator portions to be matched therewith. The diode generates DC power, showcasing Kawashima's innovative approach to energy reception.
