An apparatus and system, as well as fabrication methods therefor, may include a unitary, substantially uniformly distributed transfer material coupled to a carrier material. More particularly, a two-way communication system having a display device and an image pickup device is provided. Cells may also be engineered to include a lethal gene, so that implanted cells can be destroyed once treatment is completed. A clutch ring actuated by an actuator is moved by the actuator between engagement with one of the connectors and engagement with both of the connectors. A pair of brackets are configured to conform to an engine bay side wall of the vehicle. It is thereby possible to lengthen the Q time from the removal of the silicon oxide film to the formation of the silicon germanium film and reduce the temperature for prebaking in the formation of the silicon germanium film.
