摘要:
A speech processing apparatus and method. The speech processing apparatus includes a microphone to receive a speech signal, an analog/digital converter to convert the speech signal generated by the microphone into a digital speech signal, and an automatic gain controller to calculate an average value of the magnitude of the digital speech signal generated by the analog/digital converter in a plurality of frames, to determine in which region of a speech signal band the average value is located, the speech signal band being divided into a plurality of regions according to the strength of speech, and to adjust gain according to a location of the average value on the speech signal band so that the strength of speech has a level of an optimal region capable of processing the speech signal. Accordingly, speech recognition may be maximized without being constrained by the distance of a speech source.

Provides is a variable displacement swash plate type compressor comprising a drive shaft, a lug plate fixedly installed at one side of the drive shaft, a swash plate dispose at another side of the drive shaft and rotated by the lug plate to vary a tilt angle thereof, a sleeve reciprocally moving along the drive shaft to let the swash plate rotate, and a spring supported between the sleeve and the lug plate, characterized in that the variable displacement swash plate type compressor comprises a restriction ring installed around the drive shaft between the lug plate and the sleeve to contact with the swash plate at a maximum tilt angle of the swash plate, wherein an end of the restriction ring is contacted with the lug plate and another end of the restriction ring is supported by the spring. Thus, since the direct contact between the swash plate and the lug plate is prevented, when the swash plate reaches at the maximum tilt angle, it is possible to reduce the noise and the wear remarkably.

A deposition source is provided which is installed in a chamber, heated by applied electric power to transfer heat to a vapor deposition material received therein and applying a vaporized deposition material generated therein to a substrate to form deposition organic electroluminescent layers onto the substrate. The deposition source includes a vessel formed of a top plate on which a vapor efflux aperture is formed, a side wall, and a bottom wall; a heating device that supplies heat to the deposition material received in the vessel, the heating device being capable of moving vertically; and a moving device that moves the heating device (or the bottom wall), the moving device (or the bottom wall) being operated in response to the signal of a sensing device on varied distances between the heating device and the surface of said deposition material. Thus, the heating device is moved downward (or the bottom wall) is moved upward by the moving device to maintain the distance between the heating device (or the substrate to be coated) and the surface of the deposition material at an initially-set value when the thickness of the deposition material is decreased.

A compressor has a housing with a sensor coupling hole and a control valve coupling hole. A support plate is configured to contact with the compressor housing, the support plate having perforations. A sensor and a control valve pass through the perforations of the support plate respectively at positions corresponding to the sensor coupling hole and the control valve coupling hole. The sensor and control valve are coupled to the sensor coupling hole and the control valve coupling hole respectively. A washer is mounted on an outer peripheral surface of the sensor. The washer passes through the support plate and is inserted into the sensor coupling hole. The washer is coupled to the sensor coupling hole to fix the sensor.
