Abstract: There is provided a multi-slot die coater in which a step is formed between rear surfaces of die blocks through a fixing block having a step portion. The fixing block has the step portion of a preset height, and any one die block is coupled to the step portion and the other die block is coupled to the other portion than the step portion, and thus the step is naturally formed between the rear surfaces of the die blocks by the coupling of the die blocks to the fixing block. Thus, it is possible to always maintain the distance of the front ends of the die blocks and the substrate, since the fixing block is fixed between the die blocks, once it is set, the coating gap does not change and is maintained during the process, thereby suppressing the widthwise coating gap deviation.

Abstract: A method of producing a lube base oil mixture includes providing a waste lubricant-derived refined oil fraction derived from a waste lubricant containing a lube base oil of API Group I or II. The waste lubricant-derived refined oil fraction contains an ionic refined oil, a first regenerated base oil, or a combination thereof, dewaxing the waste lubricant-derived refined oil fraction to produce a second regenerated base oil, and blending the second regenerated base oil with a separate lube base oil to produce a lube base oil mixture of Group III or higher. The method has an economical advantage because low-quality waste lubricant is used as a feedstock for the production of higher quality lube base oils. In addition, the method is advantageous in an environmentally friendly aspect because waste lubricant is reused rather than being disposed of.

Abstract: A system and method for unsupervised stereo matching with surface normal assistance for indoor applications. According to the disclosure, a deep neural network with a feature extraction module, a normal branch, and a disparity branch is disclosed. The extraction module and the normal branch are trained first in a supervised manner for surface normal prediction. The predicted surface normal is then incorporated into the disparity branch, which is trained later in an unsupervised manner for disparity estimation. The latter unsupervised learning approach can reduce our method's dependence on a large amount of ground truth data that is difficult to collect. Experimental results indicate that our proposed method can predict accurate surface normal at textureless regions. With the help of the surface normal, the predicted disparity at these challenging areas is more accurate, which leads to improved quality of stereo matching in indoor scenarios.
