An AEC unit of an electronic cassette sets a dose target value and a short-circuited pixel used for AEC based on a radiographing condition. Separation of the flow entering the fan is reduced by extending the flare over the axial extent of the blade tip, and tip clearance losses are reduced by controlling recirculation along the entire blade tip. The encapsulant layer, which may include silicon nitride, prevents hydrogen species from escaping therethrough as high temperature processes are subsequently conducted. The first wall is disposed on a suction side of the blade and the second wall is disposed on a pressure side of the blade. By mapping x86 sources into the stack of two general purpose registers and operating x86 instructions on the x86 stack, the register stack for the processor is able to support both the processor’s native instruction set and the x86 instruction set without increasing the size of the register stack. The force and the heating initially result in deformation of the heated optical fiber.
