A polishing article and method for manufacturing a polishing article for use in a chemical mechanical polishing process is disclosed. The whip may be rotated at a sufficiently high rate, for example by a motor, so as to prevent adherence of the fluid material to the whip, for example by use of centrifugal forces to fling fluid material off of the whip. Skin contacting face-side sheets and non-skin contacting face-side sheets 6 and 10 are arranged in the crotch region. A first holding member holds the light emitting element and the first optical path converting part. The one of the optics and the carrier element comprises at least one positioning element, which passes through an opening in the circuit board and engages in a recess in the other of the optics and the carrier element. In one embodiment, exhaust gases are routed from the exhaust manifold through a cylinder and into an intake manifold.
