In some embodiments, scripts may be used to perform parcel data acquisition, conversion, and clean-uprepair in an automated manner andor through graphical user interfaces. The fan generates air flow both in the axial and radial directions, thereby increasing the number of directions in which air flows, reducing the number of fans to be used, minimizing an installation space required, and reducing noise generated by the fans. Typically, phage adsorption to target microorganisms act as signal, or a signal target, for the presence of the target microorganism. A return ring has first and second end sections, the return ring being connected to the wound claw pole stator, so that the first and second end sections are welded to each other.
