Hsiu-Chen Yang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A tube, which is especially employed for making the main frame tube of a bicycle, is fabricated by means of a 6-4Ti alloy sheet being fed to the forming mold with a feed device, being cold-rolled with the stamping block, winding the circumferential side of the forming mold as a tube blank with a spiral clearance extending along the tube blank, and welding the tube blank at the spiral clearance as a seam of the finished tube. In this way, the fabricated tube has an advantage of providing a high strength to resist being deformed easily.
