摘要:
In a method of recycling iron and steel industry waste by processing the waste as an object substance by the use of a rotary kiln, the object substance is changed into a valuable material while the object substance travels within the rotary kiln from an upstream side to a downstream side. The object substance is heated on the upstream side of the rotary kiln within a reducing atmosphere to be reduced and molten into a reduced and molten product. The reduced and molten product is quickly sent to the downstream side without being adhered to an internal wall of the rotary kiln. The valuable material is extracted from the reduced and molten product which may be directly discharged out of the rotary kiln or which may be discharged after the reduced and molten product is once kept in a basin formed in the vicinity of the downstream side of the rotary kiln.

A method for aging steel-making slag comprising the steps of charging normal temperature steel-making slag crushed to the extent that the slag having a grain diameter of 25 mm or less which constitutes 80% or more of the total amount into a pressure vessel which can be closed tight enough to seal a pressure substantially higher than atmosphere. The pressure vessel is closed and pressureized steam is supplied into the said vessel for heating the said pressure vessel and slag to raise the temperature and the pressure in the said pressure vessel while discharging condensed hot water. The interior of the vessel is kept under a condition saturated by steam and pressurized up to 2 to 10 kg/cm.sup.2 G for 1 to 5 hours. The pressure in the pressure vessel is reduced to be equalized with atmosphere. The steel-making slag is then discharged from the vessel. Apparatus is provided for carrying out the above process and includes a pressure vessel having an opening lid for charging and discharging steel-making slag. A steam generating apparatus connected via a pipe having a valve to upward of the pressure vessel. A pipe having a steam trap connected at the lower position of the pressure vessel so as to discharge hot water. A pipe having a valve connected to the upper portion of the pressure vessel and open to the atmosphere so as to reduce the pressure in the interior of the pressure vessel.

An end plate is joined to a fuel cell stack. A first piping unit and a second piping unit are attached to the end plate. The first piping unit has a first attachment base, to which a fuel gas supply pipe, a first oxidation off-gas discharge pipe, and a coolant discharge pipe are coupled. The second piping unit has a second attachment base, to which an oxidation gas supply pipe, a coolant supply pipe, and a discharge pipe are coupled. The discharge pipe is joined to a discharge cylinder coupled to the first oxidation off-gas discharge pipe. The oxidation gas supply pipe and the coolant supply pipe are integrated with each other. Also, the first oxidation off-gas discharge pipe and the coolant discharge pipe are integrated with each other.

A flexible and extensible architecture allows for secure searching across an enterprise. Such an architecture can provide a simple Internet-like search experience to users searching secure content inside (and outside) the enterprise. The architecture allows for the crawling and searching of a variety or sources across an enterprise, regardless of whether any of these sources conform to a conventional user role model. The architecture further allows for security attributes to be submitted at query time, for example, in order to provide real-time secure access to enterprise resources. The user query also can be transformed to provide for dynamic querying that provides for a more current result list than can be obtained for static queries.
摘要:
A belt drive controller for controlling each belt stopping position with high accuracy during intermittent movement of a belt. This belt drive controller controls driving of a belt to intermittently move a belt wrapped around a plurality of supporting rollers including a driven roller and a drive roller. This controller detects a rotation angular displacement or a rotation angular velocity of two supporting rollers having mutually different diameters, and controls driving of the drive roller based on the detected rotation data so that the position of the belt in the direction of movement becomes a predetermined target position.
摘要:
The object of the present invention is to provide an optical recording/reproducing method and apparatus that accurately record data blocks onto an optical disk in a seamless formation while effectively reducing the deterioration of recording properties of the disk. The recording properties of the disk may deteriorate when data is repeatedly written to a same data block of the disk. In the optical recording/reproducing method and apparatus of the invention, a read clock signal is generated in response to recorded data on an optical storage medium. A write clock signal is generated in response to a position information carrying signal detected from the storage medium. A phase difference between the read clock signal and the write clock signal is detected when writing data blocks to the storage medium in a seamless formation. It is determined whether a phase of the write clock signal is delayed or advanced based on the phase difference. In the optical recording/reproducing method and apparatus, a control signal is produced to adjust a phase of the position information carrying signal.

摘要:
An optical recording method for an optical disk having a disk surface portion in which prepits, indicative of preformat information, are formed. In the optical recording method, a portion of a data signal which matches one of the prepits and corresponds to a write mark radially adjacent to one of the prepits is detected. Marks are recorded along a track of the disk by selectively using one of an optimal recording power and a proper recording power level, in accordance with the non-match portion or the match portion of the data signal. A radial width of the marks recorded in accordance with the match portion of the data signal is smaller than a radial width of the marks recorded in accordance with the non-match portion of the data signal. An optical reproducing method is adapted to accurately detect a wobble signal and a prepit signal from the optical disk to which data is recorded by the above optical recording method. Further, a wobble/prepit detection method for optical recording and reproduction is adapted to accurately detect the wobble signal and the prepit signal from the optical disk.
