摘要:
Provided is an imaging member comprising a substrate, an undercoat layer (UCL), a charge generation layer, a charge transport layer, and an optional overcoat layer. The undercoat layer is formed from a single-phase UCL coating formulation comprising an organic titanate, a polymer containing active hydrogen, and an aminosilane. The UCL formulation has improved properties such as stability, processing convenience, and longer pot life etc. The UCL formulation can be used to manufacture an imaging member such as photoreceptor with improved properties such as stable, thick UCL coating, resistance to electrical failure, and PIDC independency on UCL thickness etc.
摘要:
A turbine blade includes a platform having a top surface, a bottom surface, and a peripheral sidewall between the top and bottom surfaces. An airfoil protrudes from the top surface of the platform. A blade mount extends from the bottom surface of the platform for attaching the turbine blade to a turbine wheel. A corrosion resistant protective coating is applied on one or more of the airfoil, the top surface, the peripheral sidewall and the bottom surface of the platform.
摘要:
A block molded from a polymeric material has a through passageway to contain a percussive shock wave. Angularly related channels communicate with the containment passageway for receiving arcuate segments of detonation cord. Alignment of a plurality of blocks provides a convenient packaging setup for the cord. A percussive signal traveling along the cord can be short-circuited in the packaging setup. A diode version of the block can react to the signal in a given direction of travel.
