摘要: An axially symmetric ring work piece is formed by a warm or hot, forward and backward extruding, die forging system. In this system, a die having a rearwardly projecting portion, which projects in the opposite direction to a pressing direction, a heated work piece, and a punch having a forwardly projecting portion, are arranged, in that order, in a container. A withdrawal die is arranged between the container, and the heated work piece, the die and the punch. The die is fixed so that a die velocity V.sub.D is 0, and the punch is moved toward the die while a punch velocity V.sub.P is set to be twice as large as a withdrawal die velocity V.sub.WD and the strokes of slide of the withdrawal die are not less than one-half of a forward-extruded foot length of a product. Thus, the forward and backward simultaneous extrusion can be substantially performed in a single-action type, short-stroke, die forging system. In addition, it is possible to effectively and accurately form a ring part, which has good metal flow and no defects, and which has a stable quality, at higher than 80 strokes per minute.

摘要: The invention provides for sharing a socket between a new-standard IC card provided with side electrodes on the sides thereof, to thereby allow the number of connections to be increased, and a current-standard IC card, and to prevent the side electrodes and the mating side electrodes of a socket from being rubbed against each other by a simple structure without any need for specific operation when an IC card is inserted or removed.
