A circuit is connected between a module and a pair of wires. The invention relates furthermore to the use of polymer mixtures of this type for various application fields, in particular for express couplings or connectors for fuel lines. Thus, a torque detecting apparatus is provided that reduces the effect of the adhesion of the magnetic dust, so as to attain higher detection sensitivity and thereby improve the detection accuracy, without incurring an increase in cost. The DNA segments are released from the substrate and held under conditions favoring hybridization of DNA, under which conditions the segments will spontaneously hybridize together to form the desired DNA construct. The second predetermined temperature is greater than the first predetermined temperature. Embodiments include forming a multilayer on the upper surface of a substrate, forming a capping layer over the multilayer, forming one or more diffuse scattering layers over the capping layer, and etching the diffuse scattering layers to form a stack.
