A process for producing a baked color pencil lead, comprising dipping a white or pale color porous baked lead having a volume-based median pore diameter of 0. The motor drive device has a control unit for outputting a first voltage in a first state in which the square sum of sampling values sampled from the two detection signals is a predetermined value, and outputting a second voltage in a second state in which the square sum is not the predetermined value. The chip utilizes the transmission characteristics of the surface Plasmon Polariton waveguide to realize the single polarization of long-distance transmission of the optical signal, and directly modulates the surface Plasmon Polariton waveguide core layer, and removes influence of the leakage light to the precision of the fiber gyroscope through the specific structure. In one exemplary implementation the resources are assigned to optimize the assignment of resources with respect to application requirements and desired objectives. Wind energy drives the turbine blades and rotor drum, which in turn drive a generator of electrical power.
