Latest Patents

Tukamoto's latest patents include an innovative electron beam welding method. This method involves forming an electron beam using a magnetic or electric field created by an even number of at least two magnetic poles or electrodes. The electron beam produced has elliptical or similarly shaped cross sections. The welding process utilizes this electron beam, ensuring that the direction of the major axis of the cross section at the surface of the material being welded is at right angles to the direction of the major axis at the root portion of the beam cavity. Additionally, he has developed a method and apparatus for electron beam welding that detects the oscillation of the focus of the electron beam due to the pulsation of a direct-current high voltage. This allows for precise control of the electron beam based on the detected oscillation.
