A test tape unit with a flexible carrier tape that can be wound forwardly by a tape drive is provided. The electronic component includes a first external supply voltage line that supplies the first circuit portion, and a second external supply voltage line that supplies the second circuit portion. As the molten metal passes through the mold channel, the metal solidifies into the shape of the mold channel. A storage system of the first secondary site includes a difference bitmap indicating an area to which data has been written from a host computer. Two devices consisting of two of these connected parts are constructed as a male device terminated by an axial stub and a female device terminated by an axial housing receiving the stub, at least two radial screws, not aligned, one of which is a cone-point set screw, connected the stub to the female device. The infusion assembly includes an abutment member and a receiving member adapted to assume, in a stationary support and guide structure, a separated open position, as well as a coupled closed position in which an infusion chamber is defined.
