Title: Combined run-length coding of refinement and significant coefficients in scalable video coding enhancement layers
Inventor: MARTA KARCZEWICZ
IPC: H04N7/32
Filed: 2012-05-22
Abstract: PROBLEM TO BE SOLVED: To provide techniques for coding an enhancement layer in a scalable video coding (SVC) scheme.SOLUTION: The techniques for coding an enhancement layer involve run-length coding of significant coefficients and refinement coefficients of the enhancement layer. Rather than performing two different run-length passes to separately code the significant coefficients and refinement coefficients, the techniques perform run-length coding of the significant coefficients and refinement coefficients together. Therefore, run values of the run-length coding codes the significant coefficients with the refinement coefficients. In addition, the need to send sign information for some of the refinement coefficients can be eliminated. Instead, this sign information for some of the refinement coefficients may be derived at the decoder based on the sign values of corresponding coefficients of previously encoded layers of the SVC scheme.

Title: Heat treatment equipment and heat treatment method
Inventor: NISHIHARA HIDEO
IPC: H01L21/26
Filed: 2012-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a heat treatment equipment capable of homogenizing temperature distribution in a circumferential direction of a substrate.SOLUTION: In a heat treatment equipment, a semiconductor wafer is rotated while being irradiated with light from a halogen lamp. The number of rotation is calculated on the basis of a target in-plane temperature distribution accuracy of the semiconductor wafer, and a heating rate of the semiconductor wafer by the light irradiation. As one example, while the temperature of the semiconductor wafer is raised by 10°C, which corresponds to the target in-plane temperature distribution accuracy, the semiconductor wafer is rotated one time or more. The higher the heating rate of the semiconductor wafer, the shorter the time required for heating the temperature by 10°C corresponding to the target in-plane temperature distribution accuracy, therefore, the number of rotation of the semiconductor wafer has to be increased. In such way, the temperature distribution in a circumferential direction of the semiconductor wafer can be controlled within a range of the in-plane temperature distribution accuracy, and can be homogenized.
