摘要:
Disclosed is an apparatus and method for preventing liquid refrigerant accumulation in an accumulator of an outdoor unit of an air conditioner. The method includes the steps of: determining a state of a compressor; if the compressor is in standby mode or off state, turning on a four-way valve; determining whether the state of the compressor in standby mode or off state continues longer than a predetermined amount of time; and if the state of the compressor continues longer than the predetermined amount of time, closing an expansion valve. Particularly, high-pressure refrigerant flows in the closed expansion valve while low-pressure refrigerant flows in a check valve through the four-way valve. The apparatus includes a suction pipe connected to spray oil of the accumulator to the compressor; a liquid recovery pipe with one end being connected to the suction pipe and the other end being connected to the accumulator; and a liquid recovery valve for controlling opening/closing of the liquid recovery pipe, in which a compressor of the air conditioner in cooling or heating mode is operated and a liquid recovery valve for controlling a liquid recovery pipe connected to the compressor and an accumulator is opened to reduce oil in the accumulator. According to the present invention, when the compressor is off, it is possible to prevent liquid refrigerant accumulation by changing refrigerant flow line to the accumulator and the refrigerant at the lower end of the accumulator can be recovered.

摘要:
A method for defect management for an optical recording medium uses a plurality of temporary defect management areas (TDMAs), so that defect management information can be recorded in prescribed areas of an optical recording medium, such as a write-once Blu-ray disc, to include information specifying the location of a last defect management area among the temporary defect management areas, to represent the most recently recorded area and therefore contain the most current information. Defect management information is recorded (updated) in one of two temporary defect management areas, with disc-in-use defect management information being recorded in one TDMA and disc-eject defect management information being recorded in another TDMA, thus recording the last defect management information of an in-use disc when the disc is ejected. A failure to record the last defect management can be recognized on the basis of an update-counter value when the use of the disc is resumed. The method includes a step of recording disc definition structure information in at least one of the plurality of temporary defect management areas, wherein the disc definition structure information includes continuously updated defect management information and locator information for accessing the continuously updated defect management information. The plurality of temporary defect management areas includes a first temporary defect management area for recording the continuously updated disc management information during a recording session and a second temporary defect management area for recording the continuously updated disc management information upon termination of the recording session.

A semiconductor device having a contact layer and a diffusion barrier layer is fabricated by preparing a semiconductor substrate forming a layer of titanium/aluminum alloy on the surface of the substrate and then heating the resultant structure in a nitrogen ambient to form a contact layer of titanium silicide interposed between the substrate and a diffusion barrier layer consisting of titanium/aluminum/nitride.

A door assembly that includes a door that is operable to alternatively expose and cover an opening in the bezel of a computer. The door assembly includes a carriage that slides up and down that pivotally couples to the door. Upon pressing against the lower portion of the door, the door pivots and the carriage and the door automatically slide down such that the door no longer covers the opening in the bezel. When an upward force is applied to the door, the door and the carriage move upward and into the closed position. As the door reaches the opening in the bezel, a spring forces the door against the bezel and into the closed position. The door is easily opened and closed and the door is out of the way when the door is in the open position.

Provided are customized archwires that facilitate wire insertion into fixed appliances and sliding mechanics during the course of orthodontic treatment. These archwires are harmonized with lingual appliances by modifying the archwire shape to alleviate the adverse effects of bends and archwire length discrepancy while maintaining the overall archwire shape. This in turn can be accomplished by selecting one or more segments of an archwire shape from a library, strategically adjusting arch length, performing morphing or smoothing operations on a wire configuration intended for final occlusion, and combinations thereof.

Electronic devices are provided with ejectable component assemblies that can be substantially flush with the external surfaces of the housings of the devices, despite variations in their manufacture. The ejectable component assemblies may include connectors coupled to circuit boards of the devices, and trays that can be loaded with removable modules, inserted through openings in the housings of the devices, and into the connectors for functionally aligning the removable modules with the circuit boards. The ejectable component assemblies may also include ejectors coupled to the housings of the devices for ejecting the trays from the connectors and, thus, from the devices themselves.
