The present invention relates to substituted benzoylguanidines of the formula I:in which R1 to R8 and X and Y are as described in the specification, and their pharmaceutically acceptable salts are substituted acylguanidines as inhibitors of the cellular sodium-proton antiporter. The network for transmitting the clock signal is such that ends of the differential signal transmission line are connected via an inductor, a low-amplitude segment is eliminated by a phase shift in the inductor and a standing wave of substantially uniform phase and amplitude is produced, wherein the number of lines connected to the grid point is made the same for entire grid points. The operating body is housed in the case vertically movable. It is determined whether a near mode used by the near FCE matches the far mode based on the mode field. It also relates to applications of this method and to structures obtained by its implementation.
