A radio frequency identification tag to be attached to printing paper includes an upper face that is opposite to a face to be attached to the printing paper, the upper face being made of a paper material substantially equal to the printing paper. The steering knuckle may have first and second circumferential surfaces that at least partially define a hole. Aspects of some methods include monitoring the output of a stabilized diode laser system to reduce noise of the output laser beam. The hi-pot testing signal generator is configured to electrically connect with and electrically disconnect from the first current input portion of the transfer table. The active layer covers at least the whole of the side walls of the first and second patterns and said predefined area of the second pattern. A third step involves providing means to circulate liquids from the well bore in through the ports into the cooling chamber and out through the ports back into the well bore, such that the liquids in the cooling chamber are continually being replaced.
