The present invention relates to an apparatus for manufacturing molten iron. The present invention provides an apparatus for manufacturing molten iron including a charge container receiving the supply of reducing material in which hot fine direct reduced iron from multiple fluidized-bed reactors are mixed; at least one pair of roller presses to which the fine direct reduced iron is supplied to undergo roll pressing, thereby producing continuous compacted material having lumped portions adjacent to each other; a crusher crushing the compacted material produced by the roller presses; and a melter-gasifier to which is charged crushed compacted material that is crushed by the crusher. Each of the pair of roller presses include pressed portions and protruded lines formed between the pressed portions. The pressed portions include first and second pressed portions opposing each other and first and second concave surfaces continuously formed on the first and second pressed portions along an axial direction of the at least one pair of roller presses, respectively. When viewed from a direction perpendicular to a plane centered between the first and the second pressed portions: (i) the first and second concave surfaces partially overlap each other, and (ii) the protruded lines are unaligned on the opposing first and second pressed portions.
Abstract:
The present invention provides a double delay-locked loop(DDLL) code tracking loop for spreading a linear section of an energy detecting area of the tracking loop by using several code time, and provides a delay-locked loop code tracking system for a receiver of a code spread communication system capable of performing an effective code tracking even when a changing ratio of a receiving path is large, by variably using a difference of a preceding time code and a delayed time code according to a change of a receiving environment being changed without cease. Accordingly, the code tracking loop of the present invention improves the receiver performance of the code spread radio communication system, and simplifies a structure of the receiver.
Abstract:
A Hadamard transformer is disclosed which uses memory cells in a digital signal processor for restoring to the original signals at a receiving end from the signals which have been transformed to a Hadamard function sequenced at a transmitting end. The Hadamard transformer using memory cells includes a counter which receives sample data clocks to output counted signals to a memory address generator and to a plurality of adder/subtractors. The plurality of adder/subtractors add and subtract the input signals and the data read from a memory in accordance with the counted signals of the counter so as to write or record the results into the memory. The memory address generator generates memory addresses in accordance with the sample data clock and the counted signals so that the memory can be read and written to. The memory thus stores the data inputted and outputted to and from the plurality of sadder/subtractors in accordance with the memory addresses generated by the memory address generator. A comparitor compares the final output values of the adder/subtractors at each period of the Hadamard function sequence so as to detect the maximum likelihood of a Hadamard function sequence.
