Gallium nitride material transistors and methods associated with the same are provided. The transistors may be used in power applications by amplifying an input signal to produce an output signal having increased power. The transistors may be designed to transmit the majority of the output signal within a specific transmission channel (defined in terms of frequency), while minimizing transmission in adjacent channels. This ability gives the transistors excellent linearity which results in high signal quality and limits errors in transmitted data. The transistors may be designed to achieve low ACPR values (a measure of excellent linearity), while still operating at high drain efficiencies and / or high output powers. Such properties enable the transistors to be used in RF power applications including third generation (3G) power applications based on W-CDMA modulation.

Gallium nitride material devices and methods associated with the same. In some embodiments, the devices may be transistors which include a conductive structure connected to a source electrode. The conductive structure may form a source field plate which can be formed over a dielectric material and can extend in the direction of the gate electrode of the transistor. The source field plate may reduce the electrical field (e.g., peak electrical field and / or integrated electrical field) in the region of the device between the gate electrode and the drain electrode which can lead to a number of advantages including reduced gate-drain feedback capacitance, reduced surface electron concentration, increased breakdown voltage, and improved device reliability. These advantages enable the gallium nitride material transistors to operate at high drain efficiencies and / or high output powers. The devices can be used in RF power applications, amongst others.

Disposal method of Barrier Lake for artificially regulating and controlling drain flow and application thereof
InactiveCN101718085AExcretion safetyFast excretionBarrages/weirsArtificial water canalsIntermediate stageDrain efficiency
The invention discloses a disposal method of Barrier Lake for artificially regulating and controlling the drain flow and an application thereof. The method comprises the following steps of: digging a draining guide slot at the part of a relatively low-lying groove on a dam body of a barrier lake; in the draining intermediate stage of a Barrier Lake reservoir, carrying out artificial explosions or mechanical clearing on huge stones influencing downward erosion development in the draining guide slot so as to guarantee the stable growth of the down cutting flow; and in the draining later stage of the Barrier Lake reservoir, when the reservoir water drain flow in the draining guide slot reaches a set threshold value, putting an artificial structural body into the draining guide slot to stabilize a slot bed so as to control the quick down cutting of the slot bed and play a role of flow control. Compared with the prior art, the invention can avoid the phenomena that the draining efficiency in the initial stage is low, and the draining in the later stage is too quick and difficult to control, which are easy to appear when a conventional method is used for disposing the Barrier Lake, thus the invention greatly improves the emergency draining efficiency of the Barrier Lake and quickly reduces the risks of the Barrier Lake so as to greatly reduce the loss of an upstream flooding area and the risks of a downstream risk area.

In an air conditioning apparatus, an evaporator is disposed in an air-conditioning case to be inclined relative to a horizontal direction and to form a lower space below the evaporator. Air flows through the evaporator from a lower side toward an upper side thereof in the air-conditioning case. The lower space is partitioned by a partition member into an air-blown space and a drain space, and a drain guide member is disposed in the drain space to approximately contact a lower end portion of the inclined evaporator, where condensed water is gathered. Therefore, it can prevent air from hitting from below against the lower end portion of the evaporator. Consequently, the condensed water that has been gathered at the lower end portion of the inclined evaporator can be discharged rapidly along the drain guide member without being affected by the flow of air, and drips to a bottom surface of the air-conditioning case. Thus, draining-efficiency of condensed water generated on the evaporator can be improved effectively.
