Disclosed herein is an apparatus. The circuit has minimal propagation delay owing to its expandable architecture which includes: an array of product term generators, a summary term generator, and a selection circuit. A CPU generates a basic connection data and a communication connection condition data. Via contacts may penetrate the dummy region, and may be connected to the first metal interconnections. thick and mass manufactured, of adjustable sizes, with combinable systems to increase their amplitude, standardized according to modern standards of popular or residential housing, characterized because it is easy to assembly, shows a high resistance to impacts and item overload, making optimum use of the available wardrobe space, with or without lateral edge reinforcement. The inventive composition exhibits low smoke generation.
