摘要： A method of making metallic iron in which a compact, containing iron oxide such as iron ore or the like and a carbonaceous reductant such as coal or the like, is used as material, and the iron oxide is reduced through the application of heat, thereby making metallic iron. In the course of this reduction, a shell composed of metallic iron is generated and grown on the surface of the compact, and slag aggregates inside the shell. This reduction continues until substantially no iron oxide is present within the metallic iron shell. Subsequently, heating is further performed to melt the metallic iron and slag. Molten metallic iron and molten slag are separated one from the other, thereby obtaining metallic iron with a relatively high metallization ratio. Through the employment of an apparatus for making metallic iron of the present invention, the above-described method is efficiently carried out, and metallic iron having a high iron purity can be made continuously as well as productively not only from iron oxide having a high iron content but also from iron oxide having a relatively low iron content.

摘要： A data device for introducing the data read from a recording medium includes first creation device for receiving a read code signal corresponding to the data stored on a data recording medium to create first two phase signals which repeat inversion with a substantially equal period to each other on the basis of a change in the waveform of the read code; second creation device for receiving the first two phase signals to create second two phase signals with their one phase occupying most of their period having an overlapping portion with each other, the period being twice as long as that of the first two phase signals; and third creation device for receiving the read code signal and said second two phase signals to create a second code signal corresponding to the read code signal which shifts during the one phase period of said second two phase signals. The second two phase signals serve to extend sufficiently the window for introducing the read code to provide stabilized read for the data including jitter due to rotation fluctuation of the recording medium.

The threshold voltage of an NMOSFET M.sub.2 constituting the CMOS inverter in the absence of substrate effect is set to be substantially equal to the threshold voltage of the NMOSFET M.sub.3 in the absence of the substrate effect, and the channel conductance W.sub.N /L.sub.N of the NMOSFET M.sub.3 is so set that the threshold voltage V.sub.LT1 of the CMOS inverter and the practical threshold voltage V.sub.LT2 of the NMOSFET M.sub.3 will be nearly the same.
