Title: Pixel block compression apparatus in an image processing system
Inventor: YU HAOPING
IPC: H04N7/50
Filed: 1997-12-17
Granted: 1999-12-11
Abstract: A memory efficient image processor (20) receives DPCM prediction error values from decompressed MPEG coded digital video signals in the form of pixel blocks containing luminance and chrominance data in a 4:2:2 or 4:2:0 format and recompresses the pixel blocks to a predetermined resolution. Luminance and chrominance data are processed with different compression laws during recompression. Luminance data are recompressed to an average of six bits per pixel, and only a reference pixel and one other pixel are processed separately from all other luminance pixels in a block. Chrominance data are recompressed to an average of six bits per pixel, and only a reference pixel and one other pixel are processed separately from all other luminance pixels in a block. Chrominance data are recompressed to an average of four bits per pixel. Each pixel block is stored with overhead information facilitating efficient and accurate reconstruction. Accurate pixel reconstruction is facilitated by processing a reference pixel accurately (31); scaling the pixel block (28); employing quantization tables (28) which are symmetrical and fitted to the domain of the pixel block; biasing negative prediction error values (27) to positive values; using short codewords in quantization tables (28) at levels which are most likely to occur statistically; and processing each pixel with three, four or five bit quantization (28) to ensure maximum resolution and an overall four-bit average for the pixel block. In a digital image processing system for receiving a data stream of compressed image pixel blocks, apparatus comprising: means for decompressing said compressed pixel blocks; a circuit for recompressing pixel representations from a decompressed pixel block such that the average number of bits for a compressed luminance pixel representation is at least one bit greater than for a compressed chrominance pixel representation; and a memory for storing said recompressed pixel representations.

Title: Method and apparatus for line or frame-synchronous frequency hopping of video transmissions
Inventor: DENT PAUL W
IPC: H04H20/00
Filed: 1998-01-26
Granted: 2000-06-11
Abstract: A method and apparatus for transmitting and receiving frequency hopped video signals is disclosed. A composite video signal is processed at a transmission end to remove line and frame synchronization codes and replace them with a frequency hopping synchronization code.  The signal is then modulated with a frequency hopped carrier signal and transmitted to a receiver.  The receiver detects the frequency hopping synchronization code to enable tuning of the receiver to the video signal.  The detected frequency hopping synchronization codes are removed and replaced with the original line and frame synchronization code.  The recreated video signal may be digitized and processed to detect and correct errors within the video signal by replacing lines or frames of the video signal with closely related lines or frames another portion of the video signal.

Title: Writing instrument and method of making same
Inventor: HORI JIRO
IPC: B43K5/18
Filed: 1999-11-26
Granted: 2001-12-11
Abstract: This invention provides a writing instrument that operates positively and that is simple in construction, and a method of making the same. The writing instrument includes a mechanism for controlling the supply of ink by means of air confined in an ink passage. Air is confined inside a blocking chamber (11) to block the ink, and a relay element (15) of a porous material is inserted into an ink holding passage (18) communicated with the blocking chamber. A root portion of the relay element forms an ink storage portion (17). When the ink in the ink storage portion is consumed, the ink inside the ink holding passage (18) will drop so that it contacts the relay element (15), which will transfer the ink to the ink storage portion, thereby preventing the porous relay element (15) from sucking air.

Title: Compressor motor
Inventor: KAWAMURA KIYOTAKA
IPC: H02K3/18
Filed: 2000-01-13
Granted: 2003-11-11
Abstract: The compressor motor of the present invention has a smaller number of connecting neutral lines than that in the conventional one to form a neutral point of a stator structure, so as to provide a highly reliable inexpensive compressor motor with a stator which can be connected easily. Three pairs (each having two poles) of coils 2u, 2v, and 2w are respectively provided for three phases of U-, V-, and W-phases, in a state where the coils 2u, 2v, and 2w are arranged facing opposite to the radial direction of a stator 1, and the coils 2u, 2v, and 2w constituting the three phases are connected in parallel with each other. A neutral point of three-phase star rectifier connection is formed by connecting the neutral lines 9u and 9w from the coils 2w to the neutral line 9v from the V-phase coil 2v at points 20uv and 20vw. Since the neutral point is formed by connecting the neutral lines 9u to 9w to each other at a total of two connecting sections, the neutral point can be formed by connecting neutral lines whose number is smaller than that in the conventional one.

Title: Uni-directional bearings structure
Inventor: CHEN SHU-KUAN
IPC: F16D41/06
Filed: 2000-02-03
Granted: 2000-12-01
Abstract: This invention relates to a uni-directional bearing structure, comprising round rollers and cam rollers adjacent to each other in sequence, provided between inner and outer collars. Each of the cam roller has a upper arc portion with radius that is slightly smaller than radius of the round roller such that the cam roller is supported by the round rollers provided at either lower sides of the arc portions. Each of the cam roller is formed with a cam portion at a lower half portion thereof. The side of the cam portion forms a curved segment. The curved segment is formed with a guiding end at a lower end thereof and the cam portion is formed with a stop end at a lower end of another side thereof. The guiding end and the stop end each have a length that is slightly larger than the gap between the inner and the outer collars, whereby when the inner collar is fitted to a spindle to perform clockwise rotation, the stop ends of the cam rollers are driven to be caught between the inner and outer collars, causing the inner collar to drive the outer collar rotating clockwise. On the contrary, when the spindle and the inner collar perform a counterclockwise rotation, the cam rollers are no longer urged between the inner and outer collars such that the inner collar slips by the guiding end and idles without driving the outer collar to rotate.
