    摘要: A method for operating a blast furnace, comprising the steps: charging iron ores and cokes through a furnace top into the blast furnace; blowing in gas containing 40 vol. % or more oxygen together with pulverized coal through tuyeres into the blast furnance; and controlling a fuel ratio within a range of 500 to 930 kg/ton., molten pig iron and still a ratio of the pulverized coal blown in through the tuyeres within a range satisfying the formula: ##EQU1## molten pig iron, where X represents a fuel ratio. Through blown-in inlets set in the furnace shaft, preheating gas is blown in to preheat burdens. The cokes charged into the blast furnace are cokes of low strength having a drum index of DI.sub.15.sup.30 of 80 to 90% .

    摘要: Herein disclosed is a cutting device for use in a tag printer or the like, in which a tag web being fed is cut, while its cut position is continuously corrected by a rotary blade so that it can cut a variety of price tag webs having different cutting pitches or intervals. The rotary blade is rotated continuously through a differential gear mechanism by a first motor. Its cutting timing is suitably corrected by a second motor which is connected to the differential gear mechanism. Before the cutting operation, moreover, both the price tag web and the rotary blade are positioned at their respective reference positions. During cutting, information as to the positions of the tags on the web and the rotary blade are fed to a processor which adjusts the rotation of the blade for effecting cutting at the proper positions along the web.

    摘要: A rotary encloder includes a rotary disk for rotating by an amount proportional to movement of an object under control and having a magnetic body on a surface thereof, and a write/read head arranged at a position opposing the rotary disk on a radius of rotation thereof for writing position information into the magnetic body on the surface of the rotary disk and for reading written information from the magnetic body. The object is positioned at a control position, control position information for controlling the object is written by a writing portion of the magnetic head at a corresponding position on the rotary disk, and the written control position information is subsequently detected by a reading portion of the magnetic head, thereby detecting arrival at a control position of the object.

    摘要: An absolute-type encoder is coupled to a drive shaft, which is rotatively driven by a motor, for detecting the amount of rotation of the drive shaft. The encoder includes a rotary disk storing position information and rotated in accordance with rotation of the drive shaft, a magnetic head for reading, in the form of a serial signal, the position information stored on the rotary disk, a counter for counting the holding information read by the magnetic head and outputting the information in the form of parallel information, and a battery for supplying operating power to the counter and magnetic head.
