摘要:
In a method for producing pig iron using iron ore with a high content of zinc, a blast furnace raw material 2 is produced using iron ore with a high content of zinc which contains 0.01 mass % or more of zinc and 50 mass % or more of iron, pig iron is produced by charging the blast furnace raw material 2 into a blast furnace 1 and, at the same time, zinc-containing dust 4 in a blast furnace discharge gas is recovered, and zinc 6 is recovered from the zinc-containing dust 4 using a reduction furnace 5. A mixed raw material into which the zinc-containing dust 4, a carbonaceous solid reducing material and a slag-making material are mixed is preferably charged on a movable hearth, and the mixed raw material is preferably reduced by supplying heat from an upper portion of the movable hearth so as to recover zinc 6 while producing reduced iron 7.

In a case where there are a plurality of spurious disturbing waves, each of which has a strong peak at a particular frequency, in a transmission band, correlation between the disturbing waves becomes nonconstant so that it becomes difficult to remove the correlation between the disturbing waves. An OFDM demodulator of the present invention includes a symbol integration circuit (131) for integrating a guard correlation signal in a symbol number direction, and an offset removal circuit (132) for removing an offset from the guard correlation signal integrated in the symbol number direction. An amplitude component due to the disturbing wave, which amplitude component is included in the guard correlation signal, is cancelled by the integration in the symbol number direction, so that it is possible to successfully remove the offset from the guard correlation signal. Therefore, it is possible to obtain symbol timing more precisely by use of a maximum value detecting circuit (124), and further, calculate a phase rotation amount more precisely by use of a phase finding circuit (125).

A pipeline closing apparatus comprises a lid member attachable to a downstream end portion of a sluice valve, a first control shaft extending through the lid member, a second control shaft extending through the first control shaft, an elastic annular member disposed between pressing plates and provided on inward end regions of the control shafts and elastically deformable to a diameter-increased position by being clamped and pressed, thereby to block between an inner peripheral surface of a branch pipe and the pressing plates, and a retaining device. The retaining device includes engaging link pairs flexing and bulging to a diameter-increased position in response to outward sliding movement of the second control shaft relative to the first control shaft. The apparatus further comprises a reversal preventing device F which, contacts and limits the engaging link pairs and to an outwardly bent position where flexing pivotal portions of the engaging link pairs project radially outward.

An advertisement management device generates and manages advertisement information and an advertisement identifier, a tag management unit generates a tag identifier and tag information unique to the tag identifier, and manages the tag identifier, the tag information, and the advertisement identifier generated by the advertisement management device in associated manner. The tag management unit sends the tag identifier and the advertisement identifier to the radio tag. A reader reads the tag identifier and the advertisement identifier from the radio tag, sends the tag identifier to the tag management unit, and sends the advertisement identifier to the advertisement management unit. The tag management unit sends tag information corresponding to the tag identifier received from the reading unit to a display unit, and the advertisement management unit sends advertisement information corresponding to the advertisement identifier received from the reading unit to the display unit.

An image correction apparatus and method enable correcting an image so that the image is always discernible and at least text can be read regardless of user settings. A correction range that increases the gray level and a correction range that decreases the gray level are calculated for each image to calculate the correction range suitable for the particular image.
