Abstract: A data receiving device may include a dummy stage block. The dummy stage block may include m dummy stages, wherein m is a natural number greater than or equal to two. Each of the m dummy stages may be configured to remove inter-symbol interference (ISI) from a dummy input signal using dummy coefficient information to generate a dummy output signal free of the ISI. Each of the m dummy stages may be further configured to output the dummy output signal. A normal stage block may include n normal stages, wherein n is a natural number greater than or equal to two. Each of the n normal stages may be configured to remove ISI from an input signal using coefficient information to generate an output signal free of the ISI and may be further configured to output the output signal.

Abstract: A preparation process of 5-ethylidene-2-norbornene, including: introducing dicyclopentadiene into a dicyclopentadiene decomposition reactor to thermally decompose the dicyclopentadiene; introducing a product of the above step into a cyclopentadiene purification tower; introducing 1,3-butadiene, a solvent, and cyclopentadiene separated from the top of the cyclopentadiene purification tower into a Diels-Alder reactor to react the same; introducing a product of the immediate above step into a 1,3-butadiene removal tower to recover 1,3-butadiene from the top; introducing a mixture at the bottom of the 1,3-butadiene removal tower into a desolvation tower, and recycling a solvent and unreacted raw materials recovered from the top of the desolvation tower to the dicyclopentadiene decomposition reactor; introducing a mixture at the bottom of the desolvation tower into a 5-vinyl-2-norbornene separation tower to separate 5-vinyl-2-norbornene; and introducing the 5-vinyl-2-norbornene into an isomerization reactor to rea

Abstract: A display device includes: a display panel including a display region and a peripheral region; a transparent protector disposed to cover the display panel; a bezel print pattern disposed between the display panel and the transparent protector and configured to form a light shield region corresponding to the peripheral region; at least one light guide film disposed between the display panel and the bezel ink pattern in the light shield region; an ultraviolet (UV)-proof printed circuit board (PCB) disposed between the display panel and the light guide film and in contact with the light guide film; and a UV curing layer formed between the display panel and the transparent protector.

Abstract: A display device, including a display panel including a display area and a non-display area, the non-display area surrounding the display area; a window facing the display panel and including a light-transmitting area and a light-blocking area, the light-transmitting area corresponding to the display area, and the light-blocking area corresponding to the non-display area; and a plurality of printed layers on the window in the light-blocking area, each printed layer including an isocyanate-blocking group having a different dissociation temperature from isocyanate-blocking groups included in other printed layers.

Abstract: A bezel structure for a display device includes a first resin layer capable of being cured by ultraviolet radiation, an ink layer including a non-volatile solvent disposed on the first resin layer, a second resin layer disposed in the ink layer, and an upper structure disposed on the ink layer. The second resin layer prevents an uncured portion of the first resin layer from permeating into a cavity in the ink layer.

Abstract: A method for preparing a transparent conducting film coated with an AZO/Ag/AZO multilayer thin film with low resistivity and high light transmittance, and a transparent conducting film produced by the same method. The method for preparing a transparent conducting film coated with an AZO/Ag/AZO multilayer thin film, includes (a) forming a primary AZO thin film on a substrate using an AZO target doped with Al through a sputtering method; (b) depositing Ag on the primary AZO thin film using the sputtering method to form a deposited Ag layer; and (c) forming a secondary AZO thin film on the Ag thin film using the AZO target doped with Al through a sputtering method.

Abstract: Disclosed is an elevator having covers capable of minimizing a generation of turbulent flows at upper and lower portions of the elevator cabin so as to reduce noise and vibration during the operation of the elevator. The elevator according to the present invention comprises upper and lower horizontal supporting members made of shaped steels having a L shape in cross section and plate strips, and covers having a dome and a truncated pyramid shape. In the elevator according to the present invention, the covers can temper impacts, due to air flows in a hoistway, against the elevator cabin during the operation of the elevator. As a result, noise and vibration due to the impacts can be reduced.
