Patent TW-401704-B (TW)
Title: Data efficient quantization table for a digital video signal processor
Inventor: YU HAO-PING
IPC: H04N7/26
Filed: 1997-12-09
Granted: 2000-08-11
Abstract: An MPEG coded and compressed video signal is received and decompressed for display. Prior to storing frames required for motion compensation in memory (14), pixel blocks are recompressed by quantizing (20) DPCM prediction error values (18) to reduce bandwidth and frame memory requirements. Fixed length quantization and dequantization tables (Fig. 2) have N levels (e.g., 15 levels), and each level has an associated output symbol of predominantly M bits (e.g., 4 bits), except that at least one of said N levels (e.g., level 7) is defined by a unique short symbol having less than M bits (e.g., 3 bits), and input data for that level is received at a desired rate. Each time a short symbol is used to represent a data value bandwidth and memory are reduced and/or preserved for other uses, for example, inserting overhead data into a fixed-size data stream. For large sequences of data, such as exists for video data for example, the reduction in memory and bandwidth is significant.

Title: Current mirror type sense amplifier circuit for semiconductor memory device
Inventor: LEE DONG-WOO
IPC: G11C7/06
Filed: 1998-11-30
Granted: 2003-06-21
Abstract: A sense amplifier circuit includes a first voltage-controlled current source to supply current proportional to a first bias voltage to a reference node and a second voltage-controlled current source to supply current proportional to a second bias voltage to a sensing node. The first and second bias voltages are internally generated in response to an externally applied sense amp control signal. A current mirror circuit is also provided for the sense amplifier circuit. The current mirror circuit commonly deliver current proportional to the voltage level of the reference node to the reference and sensing nodes. A differential amplifier amplifies a difference voltage between reference and sensing nodes. This current mirror type sense amplifier circuit allows data sensing operation to be performed without being influenced from the external conditions and without sensing speed loss due to the instability of the precharge current since the voltage-controlled current sources are controlled by the internal bias voltages.

Title: The method of producing sub-resolution phase shift pattern of the outrigger type phase shift mask
Inventor: LIN JIA-HUEI
IPC: G03F9/00
Filed: 1999-08-30
Granted: 2000-07-21
Abstract: This is a method for producing a sub-resolution phase shift pattern of the outrigger type phase shift photo mask. First, a photo mask pattern is provided. There is a main resolution pattern in the isolated pattern region and the semi-dense pattern region. Next, the main resolution pattern extends from the light-transparent region boundary to the semi- light-transparent region side for a first distance to acquire the first adjusting pattern. It extends from the light-transparent region boundary of the main resolution pattern to the semi-light-transparent region side for a second distance to acquire the second adjusting pattern. If the second distance is larger than the first distance, the first distance is the gap between the main resolution pattern and the sub-resolution phase shift pattern. The difference value between the second distance and the first distance is the width of the sub-resolution phase shift pattern. Next, the first adjusting pattern is subtracted from the second adjusting pattern to acquire the sub-resolution phase shift pattern of the outrigger type phase shift photo mask.

Title: Color cathode-ray tube device
Inventor: SANO YUUICHI
IPC: H04N9/28
Filed: 1999-12-15
Granted: 2001-06-23
Abstract: The color cathode-ray tube device of the present invention comprises a convergence correcting means 25 of a pair of side beams 18B, 18R shifting away from a center electron beam 18G relatively at the peripheral part to the phosphor screen center only along the first axis disposed on the center position between the deflection yoke 14 and the cathode of electron gun. Additionally, a deflection magnetic yoke is installed in this color cathode-ray tube device. This deflection magnetic yoke forms the deflection magnetic field along the first axis direction, which mainly is for reducing the non-uniform magnetic field component from degrading the beam spot on a phosphor screen. The deflection magnetic field along a second axis is mainly to correct the picture distortion and convergence deviating from the first axis and caused along the first axis. Hence, the length of the tube is decreased or the flatness of the picture is improved, and a good beam spot with less distortion can be formed over the screen.
