Liquid crystal display device and preparation and use thereof

A method of driving a matrix-type liquid crystal display device utilizing a liquid crystal layer sandwiched between a plurality of scanning electrodes and a plurality of signal electrodes extending generally perpendicular to the scanning electrodes, which comprises the steps of erasing a display screen by bringing it into either a light transmitting state or a light scattering state, writing by which pixels each at a point of intersection between the scanning and signal electrodes are selectively reversed in optical state, and retaining each of the pixels in the optical state once assumed immediately after the writing step. During the erasing step, all of the pixels are applied with a high alternating voltage or a high direct current voltage. During the writing step, the scanning electrodes are line-sequentially selected and the signal electrodes are applied with a signal of a waveform effective to apply a high voltage to some of the pixels desired to be reversed in optical state and a low voltage to some of the pixels desired to be retained. During the retaining step, a low alternating voltage or a low direct current voltage is applied to all of the pixels. One of the voltage wave applied to the pixels during the writing step and that applied thereto during the erasing step is high and low, respectively.

Method of driving a matrix-type liquid crystal display device

A tubular prosthesis having a composite structure comprising (i) tubular polytetrafluoroethylene having a microfibrous structure comprising small nodes interconnected with fibrils and (ii) materials which can be absorbed by a living body wherein (a) said polytetrafluoroethylene has a greater average fibril length on the outer surface than on the inner surface, and the fibrous structure of said polytetrafluoroethylene varies continuously across the thickness of the tube wall wherein said inner surface has said fibrous structure being predominantly oriented along the axial direction and said outer surface has said fibrous structure being predominantly oriented along the concentric direction; and (b) said materials which can be absorbed by a living body are collagen, at least one of albumin and chitosan, and heparin, and are distributed in such a manner that collagen is present in the portion of the tube wall which is closest to the outer surface thereof while at least one of albumin and chitosan is present in the portion of the tube wall which is closest to the inner surface thereof, and heparin is present in the inner surface of the tube wall.
