An apparatus for synthesizing polymer chains includes a controller, a plurality of precision fit vials circularly arranged in multiple banks on a cartridge, a drain corresponding to each bank of vials, a chamber bowl, a plurality of valves for delivering reagents to selective vials, and a waste tube system for purging material from the vials. In the forming step, an S-shaped offset shape is formed on a conductor part corresponding to a coil end part. One may further tune ring oscillator by varying a capacitance of at least one varactor. % with regard to the weight of the mineral binding agent. A controller receives an output from the determiner, and based on the determination, the controller controls a plurality of sections forming the radio-frequency signal receiver. The dual planetary torque transfer device is disposed in a parallel relationship with the clutch, between the input and the final output.
