    摘要: This disclosure relates to a polishing pad for chemical mechanical polishing, having a shape where 3 or more semi-oval or semicircular curves that connect 2 valleys neighboring on the plane are connected, and including 2 or more modified patterns that are formed to a determined thickness on the polishing pad, wherein a peak of one modified pattern and a valley of another modified pattern neighboring thereto are sequentially located on the same line. The polishing pad may uniformly disperse slurry over the whole area during a polishing process to provide improved polishing uniformity, and appropriately control residence time of the slurry to increase polishing rate.

    摘要: A method for modeling a roadway and a method for recognizing lane markers based on the modeling method. The method for recognizing lane markers of roadway for a vehicle by getting image information about the roadway and information about the speed and steering angle using a camera and a sensor attached to the vehicle, includes the steps of modeling the actual roadway on which the vehicle travels, as a structure having a plurality of rectangular plates linked to each other. The modeled plates are overlayed onto the image information about the actual roadway, photographed by the camera, pixels forming the lane markers are extracted, and linear lane marker information is then obtained from the pixels forming the land markers. Then, the linear lane marker information is overlayed onto the modeled plates to recalculate lane marker information using the plates as a frame, and predetermined limitations of the features of the lane markers are applied to the plates onto which the linear lane marker information has been overlayed, to optimize the lane marker information. Then, the roadway on which the vehicle is traveling, is remodeled using the optimized lane marker information, the information about the speed and steering angle of the vehicle measured by the sensor, and the information about the modeled plates, and the position and orientation of the remodeled plates are calculated. Therefore, roadway recognition can be easily achieved using a modeled structure of the roadway, in which a plurality of rectangular plates are linked. Also, the model roadway is repeatedly mapped onto the actual roadway image, so that reliability in recognition of roadway increases.

    摘要: In a method for preparing cerium carbonate powder by mixing a cerium precursor solution with a urea solution and carrying out a precipitation reaction, wherein the cerium carbonate powder has a hexagonal crystal structure, by using at least one type of organic solvent as a solvent for either or both the cerium precursor solution and the urea solution, and adjusting temperature of the precipitation reaction within a range of 120° C. to 300° C. Also, the method can yield cerium carbonate powder, cerium oxide powder from the cerium carbonate powder, and CMP slurry including the cerium oxide powder as an abrasive. In the method, urea as a precipitant can improve the uniformity of a reaction, and thus it is possible to easily and inexpensively obtain cerium carbonate powder with a hexagonal crystal structure without the danger by high-temperature high-pressure and the need for an expensive system in hydrothermal synthesis.
