The invention relates to an apparatus for feeding finely divided solids, containing at least sulphidic metal concentrate, and oxygenous oxidizing gas into a suspension smelting furnace, said apparatus comprising elements for conducting solids and oxidizing gas into the suspension smelting furnace. The method for processing a data resource changing event in a mobile terminal comprises storing the data resource changing event occurring in the mobile terminal, confirming a specialist previously set to process the data resource changing event, calling the confirmed specialist to process the data resource changing event, and displaying an avatar and text according to event processing results. The first set of pads are electrically coupled to the second set of pads through the metal layer, and a pad in the second set of pads is exposed to the surface of the backside illuminated image sensor for testing. A method for producing an exhaust gas purification catalyst, includes heating a mixed solution containing a rhodium salt, an iridium salt and a reducing agent at a temperature sufficient to reduce rhodium and iridium, thereby producing bimetallic particles including an at least partial solid solution of rhodium and iridium; and supporting the produced bimetallic particles on a catalyst support. The fluorescent element comprises at least one phosphor being an europium-activated halogeno-oxonitridosilicate of the general formula EaxSiyN23x+43y:EuzOaXb. After such dummy members are disposed, an insulating film is planarized by the CMP method.
