A trim part is aligned, via a flexible, split jig, to a finished primary surface and adhered by an epoxide to a secondary structural surface. Each of the memory areas includes a normal cell array and a redundancy cell array for repairing defective cells generated in the normal cell array such that the semiconductor memory device is usable even when memory arrays include defective cells. According to some embodiments, a data path can include one or more predefined paths through the content. An information transmission network, to which the three independent information sources and the arithmetic unit are connected, permits a transmission of information between the sources of information and the arithmetic unit. The combined coverage of the face of the cavity by the sub-actuators is such that the jet break up can be achieved without resonance of the cavity in its dimension from the wall to the face.
