Abstract: Disclosed is a display system capable of achieving a prompt drive-forced function even in an environment where, as in a remote UI, a delay occurs until a change by an information providing device is reflected in an information display device. This display system is provided with an information providing device (101) and an information display device (111), said information providing device (101) comprising a communication section “a” (104) and an accumulation section (102) which accumulates scripts (103) that include displayed parts constituting displayed images and the arrangement thereof, descriptions of animation movements etc. of the displayed parts, and drive-forced flags for all of the displayed parts, and said information display device (111) comprising a communication section “b” (112), a script processing section (113), a display section (114), and a sensor determination section (115).

Abstract: Provided is a map editing-and-displaying system that acquires partial map data from a database that contains map data. The partial map data includes appended index data. The system automatically assigns a map name to the partial map data based on the appended index data. A user can then identify and select the map according to the assigned map name.

Abstract: The method for smelting copper sulfide concentrate essentially consisting of the steps of: adding SiO2 source material and CaO source material for flux to the copper sulfide concentrate, and subjecting the copper sulfide concentrate to oxidation melting to produce slag and at least one selected from the group of white metal and blister copper, so that at least part of Fe in the copper sulfide concentrate is removed to the slag while at least part of S is removed in the form of SO2, and that copper is concentrated in the form of at least one selected from the group of white metal and blister copper, and wherein the composition of the slag is controlled such that the weight ratio CaO/(SiO2+CaO) is in the ramge of 0.6 to 0.85, while the weight ratio Fe/(FeOx+SiO2+CaO) is in the range of 0.5 to 0.6.

Abstract: A prefecture name and names of cities of address index data of map-data-acquired area are compared with those of address index data of the whole country. A map name corresponding to the range of the acquired map data is assigned automatically to the acquired map data on the basis of a comparison result. A user can easily identify a map by displaying such map names in list form or in a like manner. Further, an area whose address index data include all address index data of a requested prefecture, a requested city, or the like is calculated, and map data of that area are delivered. This allows a user to acquire only necessary map data without the need for performing a complicated operation of determining an area. Thus it is provided a map editing-and-displaying apparatus that allows a user to easily recognize an area of acquired partial map data when the partial map data have been acquired on an area basis and that also allows a user to easily identify desired map data.

Abstract: A flash smelting furnace includes a reaction shaft defining a reaction chamber therein, a plurality of reaction air blowing pipes passing through the side wall of the reaction shaft for blowing reaction air into the reaction chamber, and at least one concentrate burner attached to the top end of the reaction shaft and comprising a concentrate chute, a tubular auxiliary fuel burner extending vertically through the chute, a tubular oxygen blowing pipe concentrically surrounding the auxiliary fuel burner and a dispersion cone attached to the lower end of the oxygen blowing pipe. The air from the blowing pipes disturbs the jet stream of mixed smelting material and reaction gas in the reaction chamber, thereby achieving a uniform mixture of the material and the reaction air and extending the retention time of the material in the reaction shaft.

Abstract: A method of operating a flash smelting furnace which includes a reaction shaft, a concentrate burner disposed at the top of the reaction shaft, a settler disposed with one end thereof connected to the lower part of the reaction shaft, an uptake disposed as connected to the other end of the settler, and at least one lance pipe disposed through the ceiling of the settler between the reaction shaft and the uptake and adapted to permit forced supply of at least powdery raw materials and a reaction gas into the melt in the settler includes the steps of blowing the powdery raw materials containing only a small amount of incombustible substances and the reaction gas into the reaction shaft through the concentrate burner, blowing powdery raw materials containing at least incombustible substances through the lance pipe, and employing means capable of at least retaining the heat of the melt.

Abstract: A flash smelting furnace which comprises a reaction shaft, a concentrate combustion device disposed at the top of the furnace shaft, a settler disposed with one end thereof connected to the lower part of the reaction shaft, an uptake disposed as connected to the other end of the settler and at least one lance pipe extending through the ceiling of the settler between the reaction shaft and the uptake and adapted to blow at least powdery raw materials and a reaction gas into the melt inside the settler.

Abstract: A method of recovering Zn and Pb from iron and steel dust wherein the interior of a rotary smelting furnace connected to the discharge side of a rotary kiln is heated by a burner disposed on the outlet side of the rotary smelting furnace; a heating gas is introduced into the rotary kiln to subject the iron and steel dust containing Zn and Pb which was fed in the rotary kiln to a preliminary reduction with the aid of a reducing agent and, if required, a flux so as to volatilize Zn and Pb; and the product of the rotary kiln is fed into the rotary smelting furnace with addition of a flux to melt the resultant mixture and further volatilize Zn and Pb entrained in the product.
