Title: Innovations of Tatsuo Shoji in Plasma Technology
Introduction
Tatsuo Shoji is a prominent inventor based in Nagoya, Japan. He has made significant contributions to the field of plasma technology, holding a total of 7 patents. His work focuses on creating efficient plasma generators and methods for controlling plasma distribution.
Latest Patents
One of his latest patents includes a plasma generator designed to create a spatially uniform distribution of high-density plasma. This invention features multiple antennas located on the sidewall of a vacuum chamber. An RF power source is connected to three or four antennas in parallel via a plate-shaped conductor. The length of each antenna's conductor is shorter than the quarter wavelength of the induction electromagnetic wave generated within the vacuum chamber. This design prevents the occurrence of a standing wave, thereby maintaining plasma uniformity. Additionally, the plate-shaped conductor enhances heat-releasing efficiency, contributing to the suppression of impedance.
