According to one embodiment, a word line driving circuit includes a driver and a booster circuit. The novel seam structure allows airbag cushions to be manufactured by using low tenacity yarns, preferably in the range of between about 40 cNtex and about 65 cNtex. The PMOS transistors comprise epitaxial grown sourcedrain regions that result in significant PMOS transistor drive current increase. After establishment of communication with the telephone answering window as a relay destination, the automatic relay system starts relay of communication between the node and the relay destination telephone answering window, thus providing telephone answering window service to the customer.
