A double layer capacitor comprises a positive electrode, a negative electrode made of an activated carbon, a separator provided between a positive electrode and a negative electrode, and a nonaqueous electrolysis solution. The pipe handling apparatus improves the safety and efficiency of a rotary drilling operation. Instructions are stored within the processor that, when executed by the processor, cause the processor to provide a signal incident at the output that corresponds to a signal incident at the input. 91, a method of manufacture of a biomass support and a waste water treatment system employing the biomass support are also disclosed. Thus, a plasma CVD device that makes it possible to increase gas decomposition efficiency and achieve high film deposition rate is provided. The granular platy titanate is characterized in that platy titanate is formed with a binder, and examples of platy titanate to be used include laminar titanate compounds, platy potassium octatitanates and platy composite metal titanates.
