    摘要： A DRAM semiconductor memory device with increased reading accuracy and a method for increasing the reading accuracy of a DRAM memory cell are provided. First and second bit lines are connected to a sense amplifier and are connected in each case to a further memory cell. The gates of the further memory cells are driven via a driving circuit device. An equalization voltage of the two bit lines is influenced in the event of a precharge operation, and a capacitive disequilibrium is avoided at inputs of a sense amplifier due to the voltages on the bit lines in the event of reading the memory cell.

    摘要： Disclosed is a process and device for fusing cells in which the cells are doped with magnetic particles and exposed to a nonhomogeneous magnetic field which permeates the fusion space in such a way that the doped cells collect close together, and then, in order to create the disruptions in the membrane structures of the adjacent cells, the cells are exposed either to the pulse of an electric field of at least the level of the breakdown voltage or to chemicals which cause the disruptions in the membrane structure such as polyethylene glycol, or to inactivated viruses which cause the disruptions in the membrane structure such as Sendai viruses.

    摘要： A method of and device for increasing the permeability of the skin of cellsf living beings, according to which the respective cells are introduced in the form of a suspension into an electrically conductive liquid. Thereby there is formed a physiological electrolyte solution which is passed into one of two chambers through a passage of a partition. This partition separates a container into these two chambers, each chamber having an electrode. This passage surrounds the focus of an electric field. The cells in the electrolyte solution are exposed to the electric field while passing from one chamber to the other chamber until macromolecules having a radius of at least 5 A are exchanged through the cell skin between the solution in the interior of the cells and the physiological electrolyte solution.

    摘要： A battery comprises a housing and a plurality of battery cells arranged in the housing. Each battery cell has at least one discharge valve. The battery further comprises a discharge pipe system for discharging gases released from one, a plurality of or all discharge valves of the battery cells. The discharge pipe system according to the disclosure has a plurality of separate connections for receiving the released gases and a common discharge guide into which the separate connections open and via which the released gases can be discharged out of the housing. The battery is characterized in that a protective film is arranged between the discharge valves of the battery cells and the separate connections of the discharge pipe system so that direct contact of the battery cells to the gases in the discharge pipe system is prevented.
