Abstract: A display for showing text and graphical images includes an electrically conducting layer which is connected to a shield potential, such as a ground potential, for shielding the display from external electromagnetic disturbances and preventing radiation from the display of electromagnetic disturbances generated by the display.

Abstract: In a device for producing an image with a high light intensity by an image reproduction apparatus (9) which contains light valves, a light source comprising a light-emitting diode matrix (1, 2, 3) is provided for background lighting of the image reproduction apparatus (9). An optical device (5, 8, 10) for focussing and scattering the light which is produced by the light-emitting diode (1) is arranged between the light source (1, 2, 3) and the image reproduction apparatus (9).

Abstract: A method for producing a secondary lithium cell which has at least one lithium-cycling negative electrode, at least one lithium-intercalating positive electrode, at least one separator disposed between the positive and the negative electrode, and a nonaqueous lithium ion-conducting electrolyte. The method is carried out by the electrodes and/or the separator being coated, by means of electrostatic powder coating, with wax particles which are insoluble in the electrolyte and have a melting temperature of from about 50 to about 150 ° C. and a mean particle size of from about 6 to about 20 &mgr;m, the amount of wax being between about 0.5 and about 2.5 mg/cm2 of electrode area.

Abstract: A multi-cell storage battery, in particular to a lithium storage battery, which contains a temperature control device and in which groups of one or more individual cells arranged alongside one another are separated from one another by a thermally insulating solid layer whose coefficient of thermal conductivity lies between 0.01 and 0.2 W/(m*K), the thermal resistance of the solid layer being greater by at least a factor .lambda. than the thermal resistance of the individual cell. The individual cell is connected, at least in a region free of insulating material, to a heat exchanger, the thermal resistance of the heat exchanger in the direction toward the neighboring cell being selected to be greater by at least a factor .lambda. than the thermal resistance of the individual cell and, in addition, the thermal resistance of the heat exchanger toward the temperature control medium being selected to be smaller by at least a factor of about 10 than the thermal resistance of the individual cell, and .lambda.
