Abstract: Disclosed herein are methods of substrate retention properties utilizing compression features. In one embodiment a method for producing compression features comprises: assembling a mat around a substrate to form a substrate/mat sub-assembly, disposing the mat/substrate sub-assembly within a shell to form a retention assembly, and forming a compression feature on an outer surface of the retention assembly.

Abstract: Disclosed herein is a device for preventing noise from a door window glass for vehicles, in which in an activated condition (i.e., upon the upward and downward movement of the window), smoother upward and downward movement of the window is enabled, thereby eliminating noise due to frictional contact between the window and the weatherstrip, and in an inactivated or stopped condition of the window, the confronting inside walls of the inner weatherstrip portion are supportedly brought into close contact with the opposite surfaces of the window, thereby also eliminating noise due to window rattles caused by external factors such as wind, etc.
