A fuel preprocess system for a coal combustion boiler is disclosed. The fuel preprocess system for a coal combustion boiler that dries biomass or refuse-derived fuel in accordance with the present invention can include: a dryer configured to dry the biomass or refuse-derived fuel by use of flue gas generated after combustion in the boiler; and a torrefier configured to devolatilize a fibrous component contained in the dried fuel from the fuel dried in the dryer by use of primary air that is heat-exchanged after the combustion in the boiler.

A digital broadcasting data reception unit receives digital broadcasting data. A multimedia module parses the digital broadcasting data into video and audio data to output the video and audio data. A terminal control unit receives the digital broadcasting data from the digital broadcasting data reception unit when it is transmitted to the multimedia module, and parses the received digital broadcasting data into the video and audio data. A memory unit stores the video and audio data into which the digital broadcasting data is parsed by the terminal control unit according to a control operation of the terminal control unit.

A multiprocessor system includes a plurality of masters, at least one first type of slave operating with a first clock frequency, and at least one second type of slave operating with a second clock frequency higher than the first clock frequency. An arbitrator coordinates access between the masters and the slaves via a single read/write bus path between the arbitrator and the first type of slave, and via a plurality of read bus paths and/or a plurality of write bus paths between the arbitrator and the second type of slave.

A washing-drying machine comprises a cabinet; a tub installed in the cabinet; a washing tub rotatably arranged in the tub; a water supplying pipe connected to the tub for supplying water in order that wet air can be condensed inside the tub; and a circulation duct arranged outside the tub and having both ends connected to the tub, for circulating air inside the tub therethrough. Accordingly, a drying efficiency is enhanced without increasing a size of the cabinet, and a drying time is shortened.

Provided are an arbiter capable of improving memory access efficiency in a multi-bank memory, a memory access arbitration system including the arbiter, and an arbitration method thereof, where the arbiter detects requests that are not included in a busy bank, and allows the requests corresponding to a bank receiving the largest number of pending requests priorities; and write request information generated by masters is stored in a predetermined buffer to be output as additional master request information, and provides the corresponding master with an opportunity to generate new request information.

A stable DC power system of high-voltage and good-output performance is provided by adding a 3-phase inverter, whereby modified waveform for an output control is produced and a filter to a conventional DC power system and by bridge-rectifying. The modified sinusoidal wave such as a varied wave whose upper portion ranging from 30.degree. to 150.degree. is flat of a 1/2 cycle of the sinusoidal wave, a modified wave whose portions ranging from 30.degree. to 90.degree. and from 90.degree. to 150.degree. are linear in a 1/2 cycle of the sinusoidal wave and a modified wave whose portions ranging from 30.degree. to 90.degree. and from 210.degree. to 270.degree. are recessed so as to be symmetrical with respect to a line in the whole cycle of the sinusoidal wave are used for reducing ripples of the output voltage after the 3-phase rectification.
摘要:
An apparatus and a method for precisely wavelength-tuning single longitudinal mode tunable laser beams by utilizing a wedge prism are disclosed in which, instead of a tuning mirror, a prism is rotated, so that a single longitudinal mode can be maintained without causing a mode hopping of the longitudinal mode, thereby precisely tuning the wavelength. That is, a wedge prism 4 is inserted into the single longitudinal mode tunable laser resonator, and the prism is rotated, thereby precisely tuning the wavelength of the laser beams.
