Abstract: FIELD: turbine engineering. SUBSTANCE: walls of gas ducts are made of bent plates inclined to the direction of the flow so as the outer bents point in the direction of the gas flow and form a unique smooth surface with spaces between the plates. The inner bents are clamped by holders which are secured to the casing. Each end plate is made up as a semi-oval. One end of the plate is clamped by the holders and the other end abuts tightly against the casing and form a space with respect to the it that is equal to the distance between the adjacent plates. The space between the casing, holders, and plates is filled with a liquid under pressure. Depending on a type of the unit the liquid ranges from water to liquid metals. The areas of the vanes exerted by the pressure of hot gases is provided with one-piece plates having a number of fine holes that abut each other or tightly interweaved, rigid grids. The liquid is also supplied to the space between the plates or grids and vanes under pressure through a special ring pipe. As a result the plates or grids are cooled with a liquid from one side. From the other side that is exposed to the gas flow the plates or grids are cooled owing to converting the liquid that finds its way into the spaces and holes into vapor that flows over the plates or grids and thus isolates them from the incandescent gas. EFFECT: enhanced reliability.

Inventor: KIM YONG-WOON
IPC: H04B7/005
Filed: 2003-03-13
Abstract: Methods for bit allocation and power tuning for optimizing a setup time in a multi-channel communication system. In one aspect, a bit allocation method includes measuring a signal-to noise ratio (SNR) of each subchannel of a channel, determining a greatest allocable bit number of each subchannel using the measured SNR of the subchannels, determining a sum of the greasiest allocable bit numbers of the subchannels, and determining a difference between the sum of the greatest allocable bit numbers of the subchannels and a target bit number. For each subchannels, a currently allocated bit number of the subchannel is set equal to the greatest allocable bit number of the subchannel, if the difference between the sum of the greatest allocable bit numbers and the target bit number is less than or equal to a predetermined value. On the other hand, for each subchannels, a currently allocated bit number of the subchannel is set to a value that is reduced from the greatest allocable bit number of the subchannel by a predetermined ratio, if the difference between the sum of the greatest allocable bit numbers and the target bit number is greater than the predetermined value. The currently allocated bit numbers of one or more subchannels is adjusted until a sum of the currently allocated bit numbers is equal to the target bit number. In other aspect, a transmission power of one or more subchannels is adjusted to make a margin of each of the subchannels substantially conformal.
