Abstract
A method of processing width of a superconducting wire rod is provided, in which slit processing is performed to a superconducting wire rod formed using a wide substrate, without deteriorating the superconducting feature and at high production efficiency. The method includes a step of preparing the superconducting wire rod and a step of cutting the superconducting wire rod by processing portions each having two opposing cutting portions. At least two sets of the processing portions are arranged adjacent to each other with a distance in a width direction of the superconducting wire rod so that the superconducting wire rod is interposed between the two cutting portions. Contacting positions of the cutting portions contacting one surface of the superconducting wire rod are externally positioned in the width direction of the superconducting wire rod relative to contacting positions of the cutting portions contacting the other surface of the superconducting wire rod.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
