摘要： The present invention relates to a method for manufacturing zirconium-based alloys containing niobium with superior corrosion resistance for use in nuclear fuel rod claddings. The method of this invention comprises melting of the alloy, β-forging, β-quenching, hot-working, vacuum annealing, cold-working, intermediate annealing and final annealing, whereby the niobium concentration in the α-Zr matrix decreases from the supersaturation state to the equilibrium state to improve the corrosion resistance of the alloy. Such zirconium-based alloys containing niobium are usefully applied to nuclear fuel rod cladding of the cores in light water reactors and heavy water reactors.

摘要： Disclosed is an electronic device card socket capable of preventing the breakage of a hinge and preventing noise (static), which is caused by movement between respective parts, in the tray-type card socket. The electronic device card socket according to one embodiment of the present disclosure includes a socket housing, a socket cover, an ejecting hinge part, and ejecting bar, and a movement preventing means. The socket housing has a space into which a tray equipped with a card is inserted. The socket cover is provided at the upper part of the socket housing. The ejecting hinge part is rotatably hinge-coupled to one side of the socket housing so as to push the tray forward and separate the same when the ejecting hinge part rotates. The ejecting bar is provided at the other side of the socket housing so as to move in the forward and backward directions, and is connected to the ejecting hinge part so as to rotate the ejecting hinge part when the ejecting bar moves forward and backward. The movement preventing means prevents the movement of the ejecting hinge part and/or the ejecting bar when vibration is generated between the parts of the card socket.
