A communication device for sending transmission signals for one or more mobile stations from multiple transmitting antennas is disclosed. The core sheets are placed face-to-face and a gas pressure line fitting is inserted between one edge and is welded into place. A final driver positioned at the last stage, among the drivers, is connected to an IO module connected to a driver of a hand. The second substrate has symmetrically arranged external contact surfaces that are conductively connected to the contact connection surfaces via through-contacts in the second substrate. 20% by weight manganese, and about 0. In accordance to an aspect of the present invention, it is possible to encoding and decoding an image or a video by using a bit precision.
