Title: Yasunori Ohno: Innovator in Plasma Technology
Introduction
Yasunori Ohno is a prominent inventor based in Mito, Japan. He has made significant contributions to the field of plasma technology, holding a total of 8 patents. His innovative work focuses on the development of advanced plasma-generating apparatuses that utilize microwave energy and magnetic fields.
Latest Patents
One of his latest patents is a microwave-powered plasma-generating apparatus and method. This apparatus features a plasma discharge chamber with a plasma-generation region where microwave energy is applied while introducing plasma-forming gas. A magnetic field is generated in the plasma-generation region by an electromagnetic coil that extends around the chamber. This design enhances the magnetic field in the plasma-generation region while minimizing it outside of that area. Additionally, a permanent magnet arrangement is strategically placed radially within the coil to create a unidirectional magnetic field that extends through the entire plasma-generation region in the axial direction of the coil.
Another notable patent is for a plasma-generating apparatus that employs electron cyclotron resonance. This apparatus utilizes permanent magnets to form magnetic fields, arranged to create stronger magnetic fields in the peripheral portion of a plasma chamber compared to the central portion. The design also includes a gradually increasing cross-sectional area of the plasma chamber. Furthermore, electrons are introduced into an additional plasma chamber where no electric field is applied, allowing for the generation of low-temperature plasma.
