Abstract: Disclosed are an apparatus and a method for manufacturing an implant having a screw thread on an inner peripheral surface or an outer peripheral surface thereof by die-casting or pressing an amorphous alloy. The apparatus for manufacturing an implant using an amorphous alloy includes: a heating unit for heating a pre-form formed of an amorphous alloy into a semi-solid state; a forming unit for forming a screw thread in the heated pre-form by using a pressing mold; and a cooling unit for cooling the pre-form having the screw thread.

Abstract: A color CRT having an inner shield being mounted at a frame inside a panel and a funnel to shield an earth magnetic field, in which the inner shield comprises: a vertical portion formed in parallel to the central axis of the CRT and mounted at the frame, a slope portion extended slanted against the central axis of the CRT at a rear side of the vertical portion and a notch with its central portion formed concave at the end portion of the slope portion, the opposite of the frame; and on the assumption that the entire height of the inner shield constructed with the vertical portion and the slope portion is ‘V’, a height (V1) of the vertical portion satisfies the relational expression of 0.18≦V1/V≦0.25, and on the assumption that the shortest height from a starting point of the vertical portion to the notch is V2, the height V1 of the vertical portion satisfies a relational expression of 0.40≦V1/V2≦0.54.
