Abstract:
A dispersion compensating fiber (DCF), which is an amplification medium of an S-band discrete Raman amplifier (RA), has a trapezoid core, an inner cladding surrounding the trapezoid core; and an outer cladding surrounding the inner cladding. A ring is disposed between the inner cladding and the outer cladding. The refractive index plotted across the diameter of the trapezoid core as a function of distance is substantially trapezoidal in shape. The difference in refractive index between the trapezoid core and the outer cladding is 1.2 to 1.6%; between the inner cladding and the outer cladding is 0.4 to 0.8%; and between the ring and the outer cladding is 0.2 to 0.6%. The thickness of the ring is 0.8 to 1.2 times the radius of the trapezoid core, and the thickness of the inner cladding is 1 to 3 times the radius of the trapezoid core.

Abstract:
The present invention relates to a method for forming silicon oxide films on substrates using an atomic layer deposition process. Specifically, the silicon oxide films are formed at low temperature and high deposition rate via the atomic layer deposition process using a Si2Cl6 source unlike a conventional atomic layer deposition process using a SiCl4 source. The atomic layer deposition apparatus used in the above process can be in-situ cleaned effectively at low temperature using a HF gas or a mixture gas of HF gas and gas containing —OH group.

Abstract:
A bill delivery apparatus for a wall-type automatic-teller machine according to the present invention is disposed between a cash receiving part and a cash handling part of the machine. The apparatus comprises a main body having a pair of plates spaced apart from each other at both sides thereof; a tray unit adapted to be lifted and lowered within the main body, for temporarily stacking bills introduced from the cash handling part therein; a stopper unit disposed in front of the tray unit to prevent the bills introduced from the cash handling part from deviating from the tray unit; a transfer unit disposed adjacent to the tray unit, for transferring the bills stacked in the tray unit to the cash receiving part; a driving unit for driving the tray unit, the stopper unit, and the transfer unit; and a recovering unit for storing untaken bills that has been returned from the cash receiving part. Thus, present invention provides a bill delivery apparatus for a wall-type automated-teller machine, wherein bills can be smoothly transferred between the cash handling part and the cash receiving part, the number of bills requested by a user can be delivered at a time, and bills untaken due to a user's mistake or carelessness can be separately recovered and stored to enable the machine to be used continuously.
Abstract:
A semiconductor device with a load resistor is manufactured such that a contact is formed at both ends of the load resistor, and at least one contact is formed between the contacts, in order to prevent impurities from being generated within each contact while the contacts are being generated by etching an insulation layer phenomena of electric charge build up from occurring when an etching process fabricates an insulation layer to generate the contact in a long load resistor located under the insulation layer and insulated electrically and physically.

Microwave oven including a cavity for placing food therein, a magnetron for generating a microwave, a waveguide having at least two slots for guiding the microwave from the magnetron to an inside of the cavity, and a stirrer fan rotatably mounted on an inside of the cavity for varying an interfered state of the microwaves periodically, thereby heating the food more uniformly.
Abstract:
Provided is a dispersion-shifted fiber for an optical parametric amplifier. The dispersion-shifted fiber is a silica-based optical fiber and has a large nonlinear coefficient and a small effective area. The dispersion-shifted fiber also reduces a bending loss and a splice loss due to a mode field diameter difference between it and a conventional single mode fiber. For this, the dispersion-shifted fiber comprises a rectangular core with a very small radius and a high refractive index, a depressed inner clad, and an outer clad with a ring. The core and/or the inner clad are/is doped with a heavy metal.
Abstract:
An air-conditioner having multiple compressors includes: an indoor heat-exchanger disposed indoors and heat-exchanging indoor air; an outdoor heat-exchanger disposed outdoors and heat-exchanging a refrigerant with external air; four compressors for compressing the refrigerant to change the refrigerant to have a high temperature and high pressure; and three accumulators disposed at a suction side of the four compressors and separating the refrigerant into a gas and a liquid to supply a gaseous refrigerant to the compressors. Oil can be uniformly supplied to each compressor, thereby enhancing reliability of compressors, and since the three accumulators are small with low capacities, their installation space can be easily secured.
Abstract:
A method for controlling an air conditioner having a multi-compressors can improve capability of coping with a cooling load or a heating load, reduce energy loss and improve pleasantness. The method is achieved by pre-storing compressing capacity according to a temperature difference between a previous room temperature and a desired temperature and body adaptation time; changing the desired temperature when the body adaptation time elapses while the compressors are operated after the pre-stored compressing capacity has been changed based on a temperature difference between a current room temperature and the desired temperature; and re-changing the changed compressing capacity based on a temperature difference between a current room temperature and the changed desired-temperature.
