A safety valve is positioned in supply plumbing that supplies a fluid medium such as natural gas to a point of use structure such as a home. Specifically, the invention is directed to a method for fabricating lead-free piezoelectric free standing films having enhanced piezoelectric properties. One of the outlets may be associated with a fluid pressure responsive device, such as a cleaning blade. The browsing mode can provide a menu of candidate names for annotating a face in a single image of the viewer mode. The operating member also controls the relative positions of the second valve member and the second seat.
