Publication number: 20120094123Abstract: Provided is a core wire for guide wire in which high rigidity can be attained even with a fine wire diameter so that pushability is improved while the core wire is prevented from fatigue deformation, and a method for manufacturing the core wire. This core wire 15 for guide wire is made of a Ti—Ni based alloy and has a wire diameter not larger than 0.5 mm and a Young's modulus not lower than 50 GPa. According to the manufacturing method, first, wire drawing is performed on a raw material M0 so that the raw material M0 is passed through a wire drawing dice 2 to be drawn to a certain length while the wire diameter of the core wire is reduced. Thus, a primary processed material M1 is formed. After that, the primary processed material M1 is hammered and drawn by swaging dices 5 and 5 so that a secondary processed material M2 is formed. In this manner, the core wire 15 having a wire diameter not larger than 0.5 mm and a Young's modulus not lower than 50 GPa is manufactured.Type: ApplicationFiled: March 2, 2010Publication date: April 19, 2012Inventors: Kiyoshi Yamauchi, Akihisa Furukawa, Kiyohito Ishida, Takeshi Ishikawa, Kiyonori Takezawa, Mitsuya Takezawa

Patent number: 8137297Abstract: An elastic metal strip aligning a longitudinal direction with a rolling direction of a cold-rolled plate is collected and processed to a shape including a correction plate with the longitudinal direction of the elastic metal as a width direction of a nail and a plurality of tongue strips protruded from the edge of the correction plate near the nail tip. Each tongue strip is folded and bent to form a hooked claw with a double structure of a folding part and a bending part. A nail tip of a deformed nail is inserted between the hooked claw and the correction plate to apply a restoring force of elasticity in the correction plate to the deformed nail as correction ability for deformed nails. A wrought wire rod can be used instead of a cold-rolled plate and a Cu—Al—Mn type shape-memory alloy may further be used as a raw material.Type: GrantFiled: December 20, 2006Date of Patent: March 20, 2012Assignee: Tohoku UniversityInventors: Kiyohito Ishida, Kiyoshi Yamauchi, Ryosuke Kainuma, Yuji Sutou, Toshihiro Omori, Akira Ogawa
