Title: Dqpsk delay detection circuit that produces stable clock signal in response to both i and q signals
Inventor: NAKAYA KAZUYOSHI
IPC: H04L27/22
Filed: 1993-11-25
Abstract: A DQPSK delay detection circuit is provided that can securely reproduce stable clock signal.  An absolute value circuit ABS calculates an absolute value of I signal. An absolute value circuit ABS calculates an absolute value of Q signal.  Subtraction circuit generates a P signal according to the difference between the absolute values of I signal and Q signal.  Zero-cross detection circuit detects zero-cross timing of the P signal to input it as a timing signal to the DPLL.  The zero-cross timing of the P signal can be detected even when the data pattern of I or Q signal makes it impossible to detect the zero-cross timing from I and Q signal.  Because the zero-cross timing of the P signal has a variation less than that of the zero-cross timing determined from I or Q signal, it is becomes possible to reproduce stable clock signals and in turn reliability of data demodulation can be improved.

Abstract: ABSTRACT           A multi-layer article that includes a layer of a water-soluble polymer that provides a water-removable, non-tacky film over an adhesive layer and/or acts as an adhesive for securing the multi-layer article to a substrate, such as concrete, when wetted. The article forms a water barrier capable of being secured to an area of potential water flow including a layer of flexible, water-impermeable sheet material having a continuous or discontinuous coating of a water-soluble polymer thereon.  When the water-soluble polymer is wetted to at least partially solubilize the water-soluble coating, the polymer readily adheres the article to a substrate at the area of potential water flow.  In a preferred embodiment, the flexible sheet material includes a layer of adhesive (tacky material) and the adhesive layer is coated with the layer of water-soluble polymer to eliminate the necessity of using a sheet of release paper to prevent the adhesive layer from adhering to itself, when in roll form, and during handling and installation.
