摘要:
A mesoporous alumina molecular sieve and a method of manufacturing a mesoporous alumina mesoporous alumina molecular sieve of the invention is produced without using traditionally used additives. Also, because the size and distribution of the pores can be controlled, the molecular sieve can be produced simply and economically, producing molecular sieve with high surface area and thermal stability. Further, a method of manufacturing an alumina nanotube by using a surfactant and a use of the alumina nanotube as a hydrogen storage material are provided.

Disclosure is a method for asymmetrically aligning polarizer and rubbing axes of a fringe field switching liquid crystal display, which removes a ghost image and a rubbing mura, caused by an electric field applied to a panel under a low gray scale and dark state, by twisting an optical axis of a polarizer plate and rubbing optical axes of upper and lower plates. The Disclosure aligns polarizer and rubbing axes of a lower plate into which polarizing light is incident in such a manner that an angle formed between the polarizer and rubbing axes is a first predetermined angle and aligns polarizer and rubbing axes of an upper plate through which the polarizing light passes via a liquid crystal in such a manner that an angle formed between the polarizer and rubbing axes is a second predetermined angle.

摘要:
A method of forming a photo-tailored shape memory article is described. The method includes forming an article that includes a photochemically crosslinkable polymer composition, illuminating at least two different regions of the article with different light exposures to form first and second crosslinked polymer compositions with different shape memory critical temperatures. Also described are photochemically crosslinkable polymer compositions that include a di(meth)acrylate macromer, a multifunctional thiol, and a photoinitiator.

A digital television (DTV) receiver and a decoding method are discussed. According to an embodiment, the DTV receiver includes: a receiving unit for receiving a digital broadcasting signal including a plurality of extended text tables (ETTs) that appear in transport stream packets having common PID values, each ETT comprising a section header and a message body, wherein the section header contains a table identification extension field that serves to establish uniqueness of each ETT, and wherein the message body includes an extended text message (ETM) which provides detailed descriptions of a virtual channel or an event associated with each ETT; and a program and system information protocol (PSIP) decoder for detecting the table identification extension field to determine uniqueness of each ETT and detecting at least one pertinent ETT from the plurality of ETTs using the determined uniqueness of each ETT.
摘要:
A method and apparatus for allocating a spare area to a recording medium, and a recording medium thereof. The method includes recording data in a data area of the recording medium according to a first recording operation, creating information regarding the adjusted spare area size, based on a defect contained in the recorded data, recording the information regarding the spare area and information regarding the defect, in the data recorded according to the first recording operation, as first temporary defect information in the data area, and recording defect management information for managing the first temporary defect information as first temporary defect management information in a temporary defect management information area which is present in at least one of a lead-in area, a lead-out area, and an outer area of the recording medium. Accordingly, a spare area is allocated to a recording medium according to the occurrence rate of defects in the recording medium, resulting in effective use of a data area.
