    摘要： A shadow mask for color picture tubes has a cathode-side surface covered with a heat-insulating layer, an electron reflecting and absorbing layer, and a heat-emitting cover layer. Some of the electrons are reflected while others are absorbed in the cover layer and transformed to heat, but the heat does not act directly on the mask and is emitted into the interior of the tube. Local temperature differences which particularly occur with high contrast pictures and cause partial doming of the perforated mask are reduced.

    摘要： A tissue punch for removing tissue parts from the human or animal body is described, which comprises the actual operating instrument, as well as a separate driving unit, which is connected by means of a flexible force transmission member to the operating instrument. The operating instrument comprises a surgeon-guided outer tube and an inner tube slidably arranged therein having a cutting edge for separating the tissue parts. The inner tube is also supplied with a vacuum by means of a hose connection for removing a separated tissue part from said inner tube. The operation of the inner tube or the cutting edge connected thereto, as well as the suction are controlled by a separate control unit.
