In place of a conventional septic tank, wastewater undergoes anaerobic treatment and settlement in a treatment-pipe. In one embodiment, the center of a heating area is arranged at a track edge side of a recording pattern as compared with the width-direction center position of a main magnetic pole of a recording head, and a recording magnetic field is applied while a medium is locally heated at the time of signal recording. The exemplary smartpad can include a screen, a touch sensitive display, a configurable area, a gesture capture region and a camera. When the command is associated with virtual channel switching, the control unit checks whether a channel value corresponding to the command exists in an application virtual channel table. The setting positions are typically within a central channel and the setting positions include a central setting position, suitable for mounting a single setting and two setting positions equidistant from the central setting position. In so doing, the device provides a material feeding device having a particle material container to supply particulate material in batches from the storage area to the dosing apparatus and to do so with the least possible amount of shearing forces and without significant interaction with the atmosphere.
