A grey water tank mounting and control arrangement for the recycling and storage of used water contains three plastic tanks constructed as individual standing units, which can be mechanically connected to one another and to a control unit. Connections between the feed-through input terminal 13 and the intermediate buffer circuit 14 and between the intermediate buffer circuit 14 and the feed-through output terminal 15 are established by feed-through wires 16, 17, respectively. A method of using the communication device and learning tool is also provided. A keyword stored in the alteration region is downloaded through a MODEM from a server based on, for example, user’s operations. The apparatus may also include at least one filament or filament segment capable of being heated to a temperature that can activate the precursors, and a substrate pedestal to hold a deposition substrate upon which the silicon carbide boule is grown. The support elements and methods of the present invention further ensure that functional dice are not sacrificed by being attached to reject die sites, thereby decreasing manufacturing costs while increasing yield of functional semiconductor packages.
