A ball grid array package includes a central cavity for receiving a semiconductor die therein. The cartridge case is formed by fastening upper and lower cases of synthetic resin together and has a tape leader opening formed in the upper and lower side walls of the upper and lower cases. A sliding element which runs through the projecting shape element has at least one peripheral recess, into which at least one clamping element is engaged. The power extraction unit can be provided with a control unit that has voltage detectors and that selectively connect capacitors, based on their voltages, for maximum efficiency in generating power output. For reinjection, the inner chamber can be removed from the outer chamber, and a sleeve positioned to cover the perforations and thereby form a syringe body that can be interconnected to a needle and plunger for reinjection of the collected fat. The wherein the magnetic brush is separated from the latent image carrier outside the development area.
