Title: Liquid crystal display having wide viewing angle
Inventor: SONG JANG-KUN
IPC: G02F1/13363
Filed: 1998-06-14
Granted: 2000-10-11
Abstract: A tetragonal ring shape aperture is formed in the common electrode on one substrate and a cross shape aperture is formed at the position corresponding to the center of the tetragonal ring shape aperture in the pixel electrode on the other substrate. A liquid crystal layer between two electrodes are divided to four regions where the directors of the liquid crystal layer have different angles when a voltage is applied to the electrodes. The directors in adjacent regions make a right  angle. The tetragonal ring shape aperture is broken at midpoint of each side of the tetragon, and the width of the aperture decreases as goes from the bent point to the edge. Wide viewing angle is obtained by four regions where the directors of the liquid crystal layer indicate different directions, disclination is removed and luminance increases.

Abstract: A gas storage system formed of a continuous pipe wound in plural layers, each layer having plural loops. The pipe may be distributed within a container, which may serve as a carousel for winding the pipe and as a gas containment device. When containers, each containing a continuous pipe are stacked upon each other, the weight of upper containers may be born by the walls of lower containers, thus preventing lower layers of pipe from suffering stresses due to crushing by upper layers. A method of transporting gas to a gas distribution facility including obtaining a supply of gas at a gas supply point remote from the gas distribution facility, injecting the gas into a continuous pipe bent to form plural layers, each layer including plural loops of pipe, transporting the continuous pipe along with the gas to the gas istribution facility preferably in a ship and discharging the gas at the gas istribution facility. It is preferred that cooling of the pipe during discharging of the gas be conserved so that during subsequent filling the pipe is initially cool. Also, in a further aspect of the invention, during filling, the gas pressure should be maintained as constant as possible for example by controlled release of an incompressible liquid form the pipe as the pipe is filled with gas. Energy from the incompressible liquid may then be recovered or dissipated outside of the pipes.
