The transformer comprises a transformer body and natural convection cooling type radiators for release of heat of the transformer body. The invention also relates to an associated method. By moving data in this manner, embodiments of the invention can reduce the number of necessary control signals by as much as 50% over conventional data output circuits. The net is designed to rebound balls or objects with high energy even at side angles. Exemplary methods of processing queries on the system comprise submitting a query to the network, communicating the query to each server in the network and each server looking-up on a look-up table the processing responsibilities of the servers in the network. The plurality of branch lines may include two micro strip lines that are formed on substrates having the same dielectric constant and have bent shapes in symmetry with each other with respect to a straight line.
