    • PURPOSE: A fatigue testing apparatus is provided to improve accuracy and reliability in a bending fatigue test on a plate type specimen through a simple mechanism. CONSTITUTION: A fatigue testing apparatus (100) includes a vibration generator (110), a power generator, a specimen jig part (130), and a contact maintaining part (150). The vibration generator applies vibration to a plate type specimen in the thickness direction of the specimen. The power generator supplies power for driving the vibration generator. The specimen jig part clamps the specimen, and is capable of approaching or being separated from the vibration tip of the vibration generator. The contact maintaining part applies a force on the specimen jig part toward the vibration tip so that the vibration tip is maintained to be in contact with one side of the specimen when the vibration generator is actuated.

    • PURPOSE: A stent manufacturing method is provided to easily and conveniently manufacture a stent in comparison with an existing netting method and a laser cutting method and to prevent a combining part of each base material from generating a thermal stress. CONSTITUTION: A stent manufacturing method includes a step which prepares two or more base materials of a ring shape; a step which forms an upward protrusion(12) and a downward protrusion(14) in each base material by pressurizing the base material in the diameter direction and the perpendicular direction of the base material; a step which coats the whole or part of the base material with a filler metal; a step which laminates two or more base materials in the protruding direction of the upward protrusion and the downward protrusion; and a step which combines the laminated base material by brazing. The filler metal is coated at the end of the upward protrusion and at the end of the downward protrusion, and two or more base materials are laminated so that the lower protrusion of the upper base material and the upper protrusion of the lower base material meet.
