Title: Yoshiaki Fukuda: Innovator in Antenna and Printer Technology

Introduction

Yoshiaki Fukuda is a notable inventor based in Tochigi, Japan. He holds 2 patents that showcase his contributions to the fields of antenna technology and printer systems. His innovative designs reflect a deep understanding of electromagnetic waves and the intricacies of print head operations.

Latest Patents

Fukuda's latest patents include a sophisticated antenna design. In this invention, an antenna for communicating an electromagnetic wave features a first converger that converges the electromagnetic wave. A second converger, positioned to face the first, includes a conductor plate with a through hole. This through hole is strategically sized to be significantly smaller than the wavelength of the electromagnetic wave, allowing for effective convergence of the magnetic flux. Additionally, the conductor plate is designed with a cutout extending from the through hole to its outer periphery. A converter is positioned to face the through hole, converting the converged magnetic flux into voltage.

Another significant patent involves a drive coil protection apparatus and method, along with a printer that incorporates this technology. This invention includes a rank memory that stores a preset rank value associated with a reference drive coil in the printer's print head. This rank value characterizes inherent deviations from the manufacturing process. A judgment value memory holds multiple sets of mode judgment values, each corresponding to a specific rank value. These values help determine the thermal condition of the print head and select an appropriate operating mode. The system detects voltage drops across the reference drive coil, allowing for accurate measurement of resistance changes. This innovation prevents burnout of the print head while maintaining operational efficiency.
