Fiber reinforcement rods having a combination of reinforcing fiber members coated with a UV curable vinyl ester resin material and a polybutylene terephthalatepolyether glycol or ethylene acrylic acid topcoat layer. Then, after the shot solidifies to form a casting with a captured core, the core is melted from the casting in a liquid bath, in an air furnace, or during other heat treatment of the part. Furthermore, the digital clock manager generates a frequency adjusted clock signal that is synchronized with the output clock signal during concurrence periods. Both the first and second electrical potentials are transmitted to the jaw members through the first shaft.
