A rubber composition comprises a polar group-containing diene polymer synthesized through an emulsion polymerization as a rubber component, and an inorganic filler represented by a formula of mM. Advantageously, the offset value comprises a fixed amount and a variable amount, the variable amount accounting for dynamic differences in temperature control characteristics of the first and second temperature control zones. Only the crankshaft is then rotated in the reverse direction, and the decompression cam is rotated in the normal direction by rotating the crankshaft in the normal direction by the electric motor. A transmitter at the remote service unit includes an improved transmitter architecture. In a separate feature, a vibrometer for studying the effect of sound energy on airfoils in a component is provided with a vision system.
