A cleaning apparatus is provided for a preferably planar surface, in particular a window pane, and has a wiping device and a plunger which keeps the wiping device in contact with the surface and also, by way of an open side, bears against the surface and seals it around the edge. A suction device generates a negative pressure in the plunger. The plunger is provided with driving rollers, which are actuated by motor, for moving the plunger together with the wiping device. The suction device has at least two fans which are each provided with their own outlet opening.

The invention relates to dining and/or serving cutlery made of a steel material which is formed from a ferritic core with an essentially martensitic boundary layer. In the dining and/or serving cutlery of the invention, the surface hardness of the boundary layer, determined according to the hardness test according to Vickers HV 3, is thereby greater by 30 to 300% than the lowest hardness of the core, likewise measured according to Vickers HV 3.

A semiconductor component includes a semiconductor chip having contact pads on its main face, and a wiring foil, in which are recesses for the contact pads, applied to the main face. The foil has conductor tracks on a side facing away from the main side. The conductor tracks connect the contact pads to solder contacts. The contact pads located in the recess are electrically connected via wire connections to adjacent conductor track ends. Each wire connection is surrounded with a sealing compound of a first and a second layer. A method for manufacturing a semiconductor component includes applying wiring foil to a main side of the chip, producing the wire connection between contact pads and adjacent conductor track ends, applying sealing compound to locations on the recess to completely cover the wire connection with the sealing compound, and only curing the surface of the sealing compound.
