Abstract: A method of manufacturing an LCD comprising, preparing a liquid crystal panel which comprises a substrate assembly and a polarizing plate, wherein the polarizing plate is attached to the substrate assembly, disposing a gas injecting part towards the plate surface of the liquid crystal panel, while the gas injecting part is exposed to atmospheric conditions, and applying a pressure to the plate surface of the liquid crystal panel by injecting gas through the gas injecting part. With this configuration, the present invention provides a method to remove bubbles between the polarizing plate and liquid crystal panel without the use of a chamber.

Abstract: A semiconductor device test handler for maintaining stable temperature in a test environment may include a loading unit that loads a plurality of semiconductor devices mounted on a test tray; a soak chamber configured to receive the test tray from the loading unit and to age the semiconductor devices at an aging temperature; and a test chamber configured to receive and test the aged semiconductor devices. The test chamber may include: a test board; a first chamber; a second chamber; one or more pipelines connected to the first and second chambers that allow a temperature-control medium to flow between the first and second chambers; a de-soak chamber that further ages the tested semiconductor devices so that the tested semiconductor devices substantially return to ambient temperature; and a sorting and unloading unit that sorts the tested semiconductor devices according to results of the test and that unloads the sorted semiconductor devices.

Abstract: An antenna includes branches having substantially identical shapes. The branches are symmetrically disposed about a central point and extend along at least two concentric patterns whose geometric centers coincide with the central point. The branches each include pattern-forming portions that lie entirely within the concentric patterns, and at least one connecting portion extending between and connecting the pattern-forming portions. Input/output terminals for allowing a voltage to be impressed across the branches are provided at ends of each of the branches.
