An antenna assembly for a portable terminal. The antenna assembly includes an antenna housing releasably received in the portable terminal; a cam member having at least one stopping groove formed on a surface of the cam member, and connected to the antenna housing to move linearly and reciprocally in the portable terminal; a stopper coupled to the cam member in the portable terminal to interlock with the cam member; and an elastic member providing elastic force in a direction where the antenna housing is withdrawn from the portable terminal, wherein the stopper is engaged with the stopping groove to restrain the antenna housing in an interior of the portable terminal when the antenna housing is received and locked in the portable terminal. Since the antenna assembly can be carried while being received and locked in the portable terminal, it is possible to improve design and portability of the portable terminal, and to ensure better communication quality.

Antenna assembly for portable terminal

An interface apparatus located between a chamber unit and a stepper main controller, which collectively constitute a stepper adapted to form a pattern film on a semiconductor substrate by using a photolithography process well-known in the art. The interface is adapted to detect and control abnormal operational states within the chamber unit via a main controller on the main stepper unit even if the main stepper unit and the chamber unit are made by different manufacturers.
