Latest Patents

Among his latest innovations, Funamoto has developed a method for correcting defects in patterned articles. This method involves utilizing an operative vacuum chamber equipped with a pinhole. The process is executed by positioning the area of the defect outside the chamber, followed by the operation of the vacuum chamber to initiate cold cathode discharging. This action generates particles, which are then directed through the pinhole to deposit a corrective film over the defect.

Another significant patent details a method for correcting remaining defects within patterned films formed on articles. Similar to his previous method, it includes the use of an operative vacuum chamber and pinhole, yet it additionally incorporates gas ions to effectively remove the existing patterned film and correct the defect.

Funamoto has also patented a design for a tin-free steel welded can body, produced by mash resistance welding on a lapped side portion of a can body preform. This innovative design eliminates the need to remove surface chromium from the welded section and its surroundings, thereby improving efficiency in manufacturing processes.
