A machine instruction is provided that includes an opcode field to provide an opcode, the opcode to identify a perform pseudorandom number operation, and a register field to be used to identify a register, the register to specify a location in memory of a first operand to be used. A tubular molten resin is extruded through a die between the pair of halves of the mold to dispose the insert component in the interior space of the molten resin. The frequency counter counts the number of pulses of a reference clock for each period of a rotation speed indicating signal of a spindle motor and generates a counting value. Using the method of this invention, features with large topology may be formed while keeping the wafer topology to a minimum until the very end of the process. The device includes an elastomeric mat which can be easily placed on the wheel set shaft and retaining means for retaining the elastomeric mat on the wheel set shaft.
