  • Publication number: 20220213013
    Abstract: A system of concentrating and separating waste solvent liquid includes a distillation tower, an extracting distillation unit, an extract agent recovery unit, and a vapor permeation film unit. The scheme of centrifugal distillation is specifically employed to collocate with vapor permeation to effectively concentrate the content of isopropanol in the waste solvent liquid to generate a final produce with ultra high concentration of isopropanol, and constantly recovers the extract agent. The system is able to be quickly settled to a steady state of operation with low power consumption because the extracting distillation unit has smaller size. Since no liquid is left in the extract agent recovery unit, operation risk is greatly reduced. In addition, the input feed is almost processed, overall efficiency is thus improved. The vapor permeation film unit further removes considerably little content of water from the organic solvent to increase the content of isopropanol up to 99.9% or more.

  • Patent number: 11275966
    Abstract: A calculation method using pixel-channel shuffle convolutional neural network is provided. In the method, an operating system receives original input data. The original input data is pre-processed by a pixel shuffle process to be separated into multiple groups in order to minimize dimension of the data. The multiple groups of data are then processed by a channel shuffle process so as to form multiple groups of new input data selected for convolution operation. The unselected data are abandoned. Therefore, the dimension of the input data can be much effectively minimized. A multiplier-accumulator of the operating system is used to execute convolution operation using a convolution kernel and the multiple new groups of input data. Multiple output data are then produced.

  • Patent number: 11245024
    Abstract: A method of manufacturing a semiconductor device includes forming a fin structure comprising alternately stacked first semiconductor layers and second semiconductor layers over a substrate. A sacrificial gate structure is formed over the fin structure. Spacers are formed on either side of the sacrificial gate structure. The sacrificial gate structure is removed to form a trench between the spacers. The first semiconductor layers are removed from the trench, while leaving the second semiconductor layers suspended in the trench. A self-assembling monolayer is formed on sidewalls of the spacers in the trench. Interfacial layers are formed encircling the suspended second semiconductor layers, respectively. A high-k dielectric layer is deposited at a faster deposition rate on the interfacial layers than on the self-assembling monolayer. A metal gate structure is formed over the high-k dielectric layer.
