The present invention is directed to a dendritic polyamidoamine phthalocyanine derivative which is useful as, for example, a fluorescent material or a photodynamic therapeutic drug for cancer. The matrix material includes a sintered corrosion resistant powder and a brazing alloy. The proximal housing also is provided with a resection cavity into which the tissue to be resected is to be received. A voltage monitor monitors the voltage of the power source. According to the method of fabricating the device, a plurality of device isolation layers are formed in the substrate and then a charge storage insulator is formed on an entire surface of the substrate and the device isolation layers. Each of the vanes has a peripheral edge, and a trailing end of the peripheral edge in a vane rotation direction is located more inside than a leading end of the peripheral edge.
