For forming a preform of composite material, such as aluminum-based composite material by using friction during the forming thereof, ceramic reinforcement, such as Al2O3 and binder are prepared, and the prepared reinforcement and the silanor group binder are put into a die for press forming. According to one feature of a display device of the present invention, a chamfer portion is formed at least at an end portion of an active matrix substrate having a pixel portion of a pair of substrates disposed to be opposed to each other, and wirings over the active matrix substrate are electrically connected by a common wiring formed in the chamfer portion. The combination part is joined to the independent output interface integrated with computer main, so that the output interface integrated with computer main is joined to the input interface. In the event that both pulse signals are at the first level, a reset device resets both pulse signals to the second level. Also provided are methods and reagents for identifying panels of biomarkers associated with a condition or disorder.
