Abstract: Equipment for a continuous casting operation includes a closed chamber having first and second connecting holes, a furnace unit disposed in the chamber, a horizontal casting apparatus connected to the first connecting hole and including at least one first die having a first passage connected to the melting furnace, a first drawing unit disposed downstream of the horizontal casting apparatus, an upcast casting apparatus disposed above the chamber and connected to the second connecting hole, and a second drawing unit disposed downstream of the upcast casting apparatus. The upcast casting apparatus includes at least one second die having a second passage connected to the melting furnace. With the equipment, either horizontal casting or upcasting may be performed.

Abstract: An artificial bone includes a bone-shaped hollow metal body confining a sealed space and having two opposite closed ends, and a porous structure disposed in the sealed space. A method for making the artificial bone includes the steps of: positioning a metal tube in a bone-shaped mold cavity of a mold, hydro-forming the metal tube into a bone-shaped hollow tube in the bone-shaped mold cavity by injecting a high pressure fluid into the metal tube, disposing a crumple of metal wire into the bone-shaped hollow tube, depositing a metal coating on the metal wire and an inner surface of the bone-shaped hollow tube to form a porous structure in the bone-shaped hollow tube, and sealing the bone-shaped hollow tube.

Abstract: An electromechanical actuator structure is disclosed to include an electric actuator affixed to a base, a resilient drive member, which has a fixed segment fixedly connected to the electric actuator for synchronous reciprocating movement and a resilient segment extending out of the electric actuator and terminating in a conduction portion, a passive member mounted in the conduction portion of the resilient drive member, and a spring member mounted on the resilient segment of the resilient drive member and forcing the passive member into friction engagement with the conduction portion for enabling the passive member to be moved with the resilient drive member. By means of the amplitude of oscillation produced by the resilient drive member during displacement, the amount of displacement of the passive member is enlarged, and therefore the displacement speed of the passive member is increased and the working frequency of the drive pulse is lowered.
