摘要： A plasma display device is provided with a gas discharge device which is filled with hydrogen as an ionizable gas and contains an aluminum cathode which is maintained continuously coated during the gas discharge with a film of an aluminum oxide which is either resistant to the hydrogen gas discharge, or the non-resistant portions of which are re-formed into the oxide by means of an additive. This plasma display device can be provided for flat picture screens, particularly of television sets, because during the required life of the gas discharge device, a premature rise of the operating voltage is prevented and, at the same time, there is little sputtering effect.

摘要： Gas discharge display device having a vacuum-tight envelope with a front and back plate. A control unit divides the interior of the envelope filled with gas into a back and front space. The back space has at least one plasma cathode and at least one plasma anode. The front plate carries a cathodoluminescent layer and a layer electrode. The control unit contains at least one electrode plane extending parallel to the wall plates, with at least one conductor. In operation a gas discharge burns between the plasma electrodes. The distance between the post-acceleration anode and cathode is small such that no gas discharge is ignited in the post-acceleration space. The post-acceleration cathode is coated with an implantation protection layer of a high-melting metal to maintain the operating voltage constant under continuous load.

摘要： A method for preparing superconductive Nb.sub.3 Sn layers on niobium surfaces for high frequency applications in which a defined reaction zone which contains a tin source and the niobium surface is formed in an open reaction chamber and sealed off to the extent that, while interfering gases are being drawn off from the reaction zone during the evacuation, the vapor pressure of the tin remains higher within the reaction zone, when heated, than in the rest of the chamber. While pumping continuously, the reaction zone is then heated to a temperature between 930.degree. and 1400.degree. C and held at this temperature until an Nb.sub.3 Sn layer 0.5 to 5 .mu.m thick is formed on the niobium surface.

摘要： A magnetic head comprising a stratified buildup on a non-magnetic substrate for a recording medium to be magnetized vertically comprises a ring head-like conducting body for carrying magnetic flux having two magnet legs which comprise several magnetic layers with predetermined saturation magnetization and delineate a space in between, through which the turns of an at least largely flat write/read coil winding extend. With this head it is possible to generate a sufficiently large read voltage, wherein the same advantages are present as if single-pole heads are used. The first magnet leg comprises, in the region of its pole, at least a first magnetic layer having a predetermined low saturation magnetization and the second magnet leg comprises, at least in the region of its pole, a magnetic layer, the saturation magnetization of which is larger than the saturation magnetization of the first magnetic layer of the first magnet leg, so that for the write function the pole area of the first magnetic layer is saturated magnetically due to a write current flowing in the coil winding. Preferably, the first magnet leg has, outside its pole area, at least one further magnetic layer comprising a material with a higher saturation magnetization.
