An exhaust throttling valve system is provided for a vehicle. The method comprises forming a polycrystalline semiconductive seed layer over a substrate and forming a silicon layer by depositing silicon directly on the polycrystalline silicon seed layer under amorphous process conditions at a temperature below 600 C. The apparatus includes a spinneret, a quench zone located below said spinneret, wherein cooling gas is directed inward to an expanded filament array inside said quench zone, and an applicator inside or below said quench zone, wherein the applicator contacts the filament and delivers the finish to the expanded filament array. If the organization changes one of the business requirements or develops a new business requirement, a user may modify an insurance transaction processing program to reflect the change via a rules engine. The polyurethane of the invention exhibits improved resistance to degradation by chlorine and by atmospheric fumes. A duration during which an output of the signal processing circuit is in a high level or in a low level is fixed to a period t1 or a period t2 depending on the moving direction of the magnetic mobile object.
