Abstract: A method of fabricating a metal-oxide-semiconductor (MOS) transistor is provided. First, a patterned hard mask layer with an opening therein is formed over the substrate. A spacer is formed on the sidewall of the patterned hard mask layer in the opening. An isotropic etching process is performed on the substrate to form a recess in the substrate. An ion implant process is performed on the substrate in the lower portion of the recess using oxidation-restrained ions. The spacer is removed. Then, a thermal process is performed to form a gate oxide layer on the surface of the substrate within the recess such that the gate oxide layer in the upper portion of the recess is thicker than that in the lower portion of the recess.

Abstract: A novel isoform of tropomyosin is disclosed. The isoform is closely related to epithelial human tropomyosin (hTM) and more particularly to hTM5 except the last coding exon. The novel isoform, is called TC22. Northern blot analysis with TC22-specific probe revealed that normal culture cell lines and normal epithelial tissues expressed very little, if at all, TC22 message, whereas their transformed counterparts and tumor tissues including dysfunction of the alimentary canal, significantly increased the expression of TC22. Assays directed at determining the level of TC22 are useful in diagnostics and therapeutics of dysfunction of the alimentary canal. Specific antibodies and mimics for TC22 are also disclosed for use in diagnostics and therapeutics of dysfunction of the alimentary canal.

Abstract: A format converting and recording method and system for optical storage media including the steps of converting several first optical storage medium information files into the second optical storage medium through generating corresponding navigation tables which gather at a management file, transmitting image of the first optical storage medium to the second optical storage medium, and then generating a destination disc according to the management file. Thus, the operation process is simplified and the problem of lacking in playback control is solved.

Abstract: A computer optical disc drive and video/audio broadcasting and digital recording method thereof is described. The computer optical disc drive has a plug located outside of the main body of the optical disc drive and the plug is connected to a first interface connector electrically connecting to the circuit board of the main body of the optical disc drive. The plug may have a network connection card inserted at the time the optical disc drive plays video/audio data and thus transmit the video/audio data in the wireless manner to the receiver. Or the plug may further have video/audio multi-media card inserted when the optical disc drive performs digital recording, thereby the multi-media card would receive the video/audio data output from the video/audio broadcasting device and compress and transmit them to the optical disc drive.

Abstract: The present invention discloses a halftone processing of image and text auto detection, which is used to keep both the bit depth of images and the clarity of text when faxing or copying documents. The process of the present invention is stated as follows: choose the background color from the master copy, separate the content of the master copy into images and text with the chosen background color as the criterion, process the images with halftone processing, process the text with link art processing, and then output the processed images and processed text as a whole.

Abstract: The present invention provides a fixing seat of main transmission shaft of a scanner, wherein a conical hole is formed on the surface of a main transmission shaft whereon a scanning head can move, and a belt conveyor is used to wind around a timing pulley and an idle pulley. The timing pulley is driven to rotate by a motor device so that the belt conveyor can drive the scanning head to move on the main transmission shaft. One end of an axis of the timing pulley protruding out of the surface thereof forms a slanting conical end, which is fixed in the conical hole. The present invention has the advantages of high stability, good reliability, and a low manufacturing cost.

Abstract: A method of coding video pictures in a PB frames mode comprises the steps of: a) initializing a sum value; b) determining, for each block of a picture, a block motion vector, defining the block motion against the previous picture; c) computing a value indicating of the amount of each block motion vector and comparing each indicative value against a first predetermined threshold value; d) for each block motion vector, if the indicative value thereof exceeds said first predetermined threshold value, incrementing said sum value; e) if, after completing the comparison for all block motion vectors, said sum value exceeds a second predetermined threshold value, then; f) coding the video picture as comprising at least one P-picture, but no B-picture.

Abstract: A method and apparatus for out-of-order memory processing within an in-order processing device includes processing that allows a plurality of memory transactions to be processed in a pipeline manner until a dependency arises between two or more memory transactions. Such processing includes, for each of the plurality of memory transactions, determining whether data associated with the transaction is stored in local cache. If the data is stored in local cache, it is written into a data register in a next pipeline interval. The processing continues by storing the memory transaction in a miss buffer when the data associated with the memory transaction is not stored in the local cache. The processing continues by writing the associated data for the memory transaction identified in the missed buffer into the data register when the data is received without regard to the pipeline manner.

Abstract: A rectangular metal slice is cut into antenna sheet material. The antenna sheet material is further folded up to form the antenna. The antenna sheet material includes a radiating plate, a feeding plate, and a ground plate. The length of the radiating plate is approximate quarter wavelength corresponding to the operating frequency. The main feature of the antenna, according to the invention, is that the feeding plate and the ground plate extend in the same direction, thereby reducing the scale of the antenna.
