Abstract: An apparatus for preventing an axial-flow compressor from stalling by employing a casing treatment includes an outer casing having an inner wall with a slot formed to face a rotor blade, an inner casing moveable so as to open the slot in an unstable operating region and close the slot of the outer casing in a stable operating region, and a drive means for moving the inner casing along the axial direction of the outer casing. Thus, the apparatus can be applied not only to a casing treatment structure where the slope of a slot does not vary with the rotational position of the rotor, but also to a casing with a variously shaped slot such as a radial slot or an axial skewed slot.

Abstract: A fluid stabilizing control method of an axial compressor is provided, which includes driving to drive the axial impeller, and stall controlling to suppress or prevent an occurrence of a stall that may transpire during rotation of the axial impeller by supplying highly-pressurized compressed air into the casing through a stall controller according to a predetermined time and volume. Accordingly, a stall may be suppressed or prevented, the occurrence of a stall that may transpire when a threshold point is exceeded by an unexpected event during driving in a low-flow high-pressure section on a performance curve, in which efficiency is high. Additionally, since an air injection method for suppressing the stall is properly applied, an amount of power expended for the stall control may be reduced while supply of the high-pressure compressed air is minimized, thereby achieving economically feasible stall control.

Abstract: In a display apparatus, an Electric Program Guide (EPG) is distinctively displayed to overlap with current broadcasting data being displayed. A method for displaying EPG includes determining whether an EPG display request signal is received while broadcasting data is displayed. When the EPG display request signal is received, at least one of brightness and chroma of a screen displaying the broadcasting data is modified. The EPG is displayed on the screen so that the displayed EPG has a different brightness or chroma than the modified brightness or chroma of the screen. This may improve recognizability and/or legibility of EPG by employing a modification in brightness or chroma when the EPG is displayed on current broadcasting data. For further improved recognizability and/or legibility, a border effect or a blur effect may be applied to a user's selected item in the displayed EPG.
