A hybrid vehicle control apparatus controls an engine that rotates at least one first wheel and a mechanically independent electric motor that rotates at least one second wheel. An intermediate aluminum ring is mounted on the outer circumference of the weight center of a fan motor, having a swing spindle provided with at least one first bearing, and a threading spindle disposed at the other end set therein with a second bearing. A passive combiner or a 1\xd72 switch is provided at the branch unit, along with a detector and a processor, to determine whether any signals are being received from the service path, and if not, to reconfigure the system to accept signals from the protection path. Each of the scaled discrete cosine transform constants are then represented with approximated sums of powers-of-2. The first separator has a plurality of sieve mat supports alternately connected to a main support frame section and a movable support frame section so that the flexible sieve mat can be agitated by the movable support frame section, a collector being provided for collecting the primary treated slurry passing through the flexible sieve mat.
