Title: Process and apparatus for producing metal from metal ores
Inventor: JANZ JOACHIM
IPC: C21B5/02
Filed: 1999-04-12
Granted: 2003-03-11
Abstract: The invention concerns a process and an apparatus for producing metal from metal ores, in particular crude or pig iron from iron ore, in which the ore which contains metal oxides is brought into reaction contact with a reducing gas which contains carbon and/or hydrogen (and possibly compounds thereof) and which was previously obtained from solid, carbon-bearing and/or hydrocarbon-bearing substances. It is known that the ore which for the major part comprises metal oxides (being various ones, even in the case of iron) must be subjected to a reduction procedure before the metal can be obtained. Taking the known process as set forth in the opening part of this specification as its basic starting point, the object of the invention is to make plastic waste, including in organically and/or inorganically contaminated form, useable as a supplier for the constituents of the reducing gas. Plastic waste occurs constantly in large amounts and represents a serious disposal problem. It occurs mostly if not exclusively in solid form, either as packaging waste -which is frequently heavily contaminated-, or as offcuts or the like in the course of the production of plastic articles. Accordingly the invention provides that the carbon-bearing and/or hydrocarbon-bearing substances, at least partially comprising plastic material, which in the process of the general kind set forth in the opening part of this specification are supplied to obtain the reducing gas, are injected in comminuted fluidised form as an agglomerate into the air flow in the hearth of the metallurgical shaft or pit furnace, in particular a blast furnace. That is effected by way of lances which project into the shaft furnace and which are connected to a transport conduit. The plastic material to be injected is fed to the lances by way of that transport conduit. In the event that, contrary to expectation, blockages should occur or hot air should blow back out of the blast furnace into the lance and thus into the transport conduit, a plurality of shut-off or check devices are proposed in the transport conduit, so that the transport conduit is not only protected but immediate resumption of overall operation of the installation and injection of the plastic materials occurs. To dissolve blockages of the plastic material in the transport conduit, there are provided a first and third shut-off device, while a second shut-off device is provided to prevent reverse transportation of plastic material or blow-back of the hot gas masses from the blast furnace into the transport conduit. The mode of operation thereof is set forth in greater detail in the claims but in particular also in the specific description.

Title: Liquid crystal display device
Inventor: HIROKI MASAAKI
IPC: G02F1/133
Filed: 1999-04-20
Granted: 2004-10-01
Abstract: Disclosed is a high-definition liquid crystal display device wherein a video signal applied to the pixel electrode is compensated for a gain decrease in a high frequency range. A video signal processing circuit includes an inversion processing circuit which outputs at least one video signal inputted to a source driver circuit. The inversion processing circuit includes an amplifier and has function of amplification and inversion. A peaking processing circuit is connected to an amplifier in the inversion processing circuit. Even if a video signal frequency fvid is in a high range of the amplifier, the amplifier gain is increased up to a middle range value (frequency range that the gain becomes constant). Because the peaking circuit compensates for characteristics of the liquid crystal panel, it is possible for the inversion processing circuit to apply an alternating current signal reproduced with fidelity of a potential determined by a correction circuit to the liquid crystal cell.

Title: Variable speed change gear
Inventor: MIMURA KENJI
IPC: F16H29/12
Filed: 1999-06-03
Granted: 2002-07-21
Abstract: When second rotating bodies are made eccentric, the second rotating bodies move straight in the radial direction along first rotating bodies. Therefore, the cyclically changing angular velocity of the second rotating body changes so that the side on which the angular velocity is higher than the angular velocity of the input-side rotating body and the side on which the angular velocity is lower are symmetrical to each other. Also, on both of the side on which the angular velocity is higher and the side on which it is lower, the acceleration side and the deceleration side change symmetrically to each other. On the other hand, the angular velocity of the second rotating body such that the movement direction with respect to the first rotating body is shifted 180 degrees with each other with the input-side rotating body being the center changes symmetrically with respect to the angular velocity of the input-side rotating body. Moreover, since the second rotating bodies have the same mass, the radial forces of the second rotating bodies are canceled each other, so that the rotational force always acts with the input-side rotating body being the center.
