Title: Quantization in perceptual audio coders with compensation for synthesis filter noise spreading
Inventor: UBALE ANIL WAMANRAO
IPC: G10L19/00
Filed: 2000-04-11
Granted: 2003-05-11
Abstract: Many perceptual split-band coding systems that use analysis and synthesis filters assume the quantization noise introduced by quantizing split-band signals is substantially the same as the noise that results in the output signal obtained by applying the synthesis filters to the quantized split-band signals. In general, this assumption is not true because the synthesis filters modify or spread the quantization noise. A theoretical framework for deriving an optimum bit allocation that accounts for synthesis-filter noise spreading is disclosed. In concept, the problem of finding an optimal bit allocation can be expressed as a linear optimization problem in a multidimensional coordinate space. Simplified processes derived from this theoretical framework are disclosed that can obtain near-optimal solutions using modest computational resources.

Title: Light guide plate, surface light source device of side light type and liquid crystal display
Inventor: OHKAWA SHINGO
IPC: G02F1/13357
Filed: 2000-08-21
Granted: 2004-11-01
Abstract: Cylindrically curved slopes successively inner-reflect the illumination light which reaches a back face or emission face of a light guide plate via an upper edge of an incidence face. The curved slopes give the light diverse propagation directions after inner-reflection. This avoids the viewer from observing a strongly irradiated edge, thereby reducing the reflective appearance. The inner-reflection by the curved slopes also gives diverse propagation directions to illumination light coming via the other edges, thereby reducing the reflective appearance. The curved surface profile is given to the valleys involved in a great number of projection rows running in a direction approximately perpendicular to the incidence face, and may be further given to the projection rows. The valleys are provided with curved surface profile within a curved-surface-profile-giving-area around the incidence face or, in addition to this, around the flank faces of the light guide plate. The curved surface profile varies gradually around a boundary of the curved-surface-profile-giving-area to avoid the sudden profile changing which would bring undesirable effects.

Abstract: A plurality of gate lines extending in a horizontal direction are formed on an insulating substrate, and a data line is formed perpendicular to the gate line thereby defining a pixel of a matrix array. Pixel electrodes receiving image signals through the data line are formed in a pixel, and a thin film transistor having a gate electrode connected to the gate line, a source electrode connected to the data line, and a drain electrode connected to the pixel electrode is formed on the portion where the gate lines and the data lines intersect. A storage wire including a storage electrode line is formed in the horizontal direction, and a storage electrode connected to the storage electrode line and forming a storage capacitance by overlapping the pixel electrode is formed in the pixel. A redundant repair line both ends of which overlap the storage wire of the neighboring pixel, and a storage wire connection line connecting the storage wires of a neighboring pixel are formed. In this structure, because the storage wires of a neighboring pixel are connected to each other through the storage wire connection line, the variation of the voltage for the storage capacitance may be minimized, and this results in a reduction of its distortion, such that crosstalk and flicker problems are minimized.

Title: Dry-type photoresist stripping for preventing substrate from peeling
Inventor: LIOU YOU-CHENG
IPC: H01L21/027
Filed: 2001-02-27
Granted: 2002-10-21
Abstract: The key point of the present invention is to change the conventional single stage of plasma dry method for stripping photoresist. In the same instrument of plasma dry-type photoresist stripping, the dry-type photoresist stripping process is divided into two stages based on the temperature such that the surface thermal stress between photoresist and the substrate is decreased. Therefore, the occurrence of substrate peeling results from the thermal stress and the hardening of the photoresist caused by the front end ion implantation process, can be avoided. In addition, the utilization of more than two kinds of dry-type photoresist stripping instruments to obtain better photoresist stripping effects and longer process time can also be avoided.

Granted: 2004-11-11
Abstract: A manufacturing method of dual damascene structure is disclosed in the present invention, in which alkali-dissolvable or water-dissolvable hole-filling material is filled into the via-hole before conducting the step of trench etching. The hole-filling material is directly developed to a certain height through the use of alkaline developer or deionized water. After that, a baking process is conducted to generate an inter-chain reaction so as to define photoresist of the trench and prevent it from generating mixture. The inner wall of the via hole and the interconnection on the substrate are protected so as to avoid the generation of bad via hole profile and punch-through caused by the damage due to etching process. Thus, it is capable of preventing fence effect when conducting the trench-etching step.
