The present invention relates to a flash memory cell and method of manufacturing the same, and programmingerasingreading method in the flash memory cell. The present invention relates more particularly to a screen cylinder formed from a plurality of screen wires leaving screening slots therebetween, and circular support elements. In the transfer device, a controller communicates with a main controller that controls the whole image forming apparatus, and acquires, for example, information on the total print count or the like. The electrical stimulators may comprise various types of electrodes such as cuff electrodes, electrode leads, and microstimulators implanted at various locations proximate to a single or both iliohypogastric nerves of a patient. A receiving and demodulating section is provided for one of the users, generates beam-corresponding correlation signals at a path timing from the beam-corresponding spread signals, and generates path signals by weighting the beam-corresponding correlation signals with adaptive weights which are updated adaptively, and produces a demodulation signal for the one user by combining the path signals.
