Abstract: A plasma processing system configured for use in processing a substrate after metal etching. The substrate includes a layer of photoresist disposed thereon. The plasma processing system includes a plasma generating region and a baffle plate disposed between the plasma generating region and the substrate. The baffle plate includes a central blocked portion disposed in a center region of the baffle plate. The baffle plate further includes an annular porous portion surrounding the central blocked portion. The annular porous portion includes a plurality of through holes configured for permitting a H.sub.2 O plasma generated in the plasma generating region to pass through the holes to reach a surface of the substrate. The plasma processing system also includes a chuck disposed below the baffle plate to support the substrate during the processing.

Abstract: The compression method utilizes a combination of both lossy and lossless compression to achieve significant compression while retaining very high subjective quality of the reconstructed or decompressed signal. Methods and apparatus for compression and decompression of digital audio data are provided. In one preferred embodiment, the compression method or apparatus has a bit rate control feedback loop particularly well suited to matching the output bit rate of the data compressor to the bandwidth capacity of a communication channel. Embodiments trade-off various error sources in order to keep perceptible distortion levels to a minimum for a fixed bit rate. Preferred embodiments also utilize a unique combination of run length and Huffman encoding methods in order to take advantage of both local and global statistics.

Abstract: A brush assembly including a brush holder having a center axle hole fixedly secured to the output shaft of a motor and two elongated slots longitudinally aligned at two opposite ends, a master cylinder brush coupled to the output shaft of the motor for cleaning the inside of the loaded cup, and two auxiliary cylinder brushes slidably and perpendicularly coupled to the elongated slots of the brush holder and fixed in place by a respective screw for cleaning the outside of the loaded cup.

Abstract: A cup washing machine includes a first transmission shaft and a second transmission shaft respectively coupled to a motor drive by a set of gears, a third transmission shaft eccentrically coupled to the second transmission shaft, a first cylinder brush and a second cylinder brush respectively coupled to the first and third transmission shafts, a toothed lock block controlled by a lock control knob to lock the third transmission in a desired angular position for permitting the pitch between the first and second cylinder brushes to be adjustably set. A detergent dispensing can with a dispensing tube is mounted on the housing of the machine and controlled to disperse detergent to the cylinder brushes for cleaning cups.

Abstract: A horizontal cup washing machine comprising a fan motor to drive a plurality of tube brushes to rotate via a gear power transmission mechanism and a plurality of output shafts. The casing of the machine has a plurality of tube brush holder means for holding the tube brushes permitting the tube brushes to be dried by the air when they are not in use. An elongated recess and a plate spring are made on the bottom edge of the casing of the machine so that it can be conveniently attached to the casing of a water faucet by a lock screw.
