Abstract: An apparatus for manufacturing a display module includes a stage and a mask disposed over the stage. The mask includes a body, a frame that at least partially surrounds the body, and a plurality of bridges that are disposed between the body and the frame and that extend from the body toward the frame. A plurality of openings are defined between the bridges.

Abstract: A cover layer manufacturing method includes: a first applying process, which forms a first cover layer on a rear surface of a first display panel using a first mask in an applying unit; a first cleaning process, which cleans a second mask in a cleaning unit; a rotating process, which changes a position of the first mask and a position of the second mask using a rotation driver; a second applying process, which forms a second cover layer on a rear surface of a second display panel using the second mask in the applying unit; and a second cleaning process, which cleans the first mask in the cleaning unit. The first applying process and the first cleaning process are substantially simultaneously performed, and the second applying process and the second cleaning process are substantially simultaneously performed.

Abstract: A method for modeling gas production in a coalbed methane gas (CBM) reservoir including (a) dividing a reservoir in a CBM development area into three-dimensional grids to form the three-dimensional grids having a plurality of cells; (b) forming at least one drilling hole in the development area and obtaining a sample for each depth in the reservoir; (c) modeling the amounts of ash, water, and gas for the plurality of cells in the three-dimensional grids; (d) modeling a pressure change over time in each of the cells in the grid under a premise in which a production well is formed in the grids; and (e) performing a Langmuir experiment for a core sample obtained from step (b).

Abstract: The present invention includes (a) dividing the reservoir in a coalbed methane (CBM) development area through computer modeling and thereby forming a three-dimensional grids having a plurality of cell, (b) actually forming drilling holes in the development area and thereby obtaining core samples for each depth, (c) modeling the amounts of ash, water, and gas in each of the cells, (d) modeling the pressure change over time in each of the cells under a premise in which a production well is formed in the grids, and (e) performing a Langmuir experiment for the core samples, determining a Langmuir function for a maximum amount of gas adsorption with pressure and amounts of ash and water as variables, and applying the Langmuir function to each of the cells to calculate an amount of gas detected due to pressure change over time.
