A method is disclosed for identifying a device address of a destination device having a device address unknown to a source device. The AC power to the motor may be stepped down by using a clipper circuit, while the DC power supplied to the motor may be increased by switching motor field windings from a series wound circuit to a parallel wound circuit. Cutting edges are formed on the longitudinal edges of the end portions, whereby a central fastening opening is provided in the central portion for mounting the cutting blade on a drive shaft. The phase transition temperature of the cold insulation member is in a range between the predetermined operational temperature and an upper limit of the predetermined temperature range. The invention further relates to processes for isolating such stem cells using these antibodies.
