The disclosed invention provides a structure and method for detecting address line memory failures. Such compounds are represented by Formula I as follows:wherein A, G, Y, R3, R4, and R5 are defined herein. The method further includes initiating restoration procedures by performing an initial registration. An orifice passage, formed in the detector, connecting a tank passage to a sensor passage communicating with a sensor chamber where a pressure sensor is disposed is slanted relative to the tank passage to shorten the passage distance up to the pressure sensor. Accordingly, a plurality of web applications can be controlled independently, so the user’s convenience can be improved. The configuration of the chords and web permits rapid fabrication of the truss.
