A porous silica precursor composition is herein provided and the precursor composition comprises an organic silane represented by the following chemical formula 1: R1m(R2—O)4-mSi (in the formula, R1 and R2 may be the same or different and each represent an alkyl group, and m is an integer ranging from 0 to 3); water; an alcohol; and a quaternary ammonium compound represented by the following chemical formula 2: R3N(R4)3X (in the formula, R3 and R4 may be the same or different and each represent an alkyl group and X represents a halogen atom). The composition is prepared by a method comprising the step of blending the foregoing components. The porous silica precursor composition is coated on a substrate and then fired to thus form a porous silica film. Also disclosed herein include a semiconductor element, an apparatus for displaying an image and a liquid crystal display, each having the foregoing porous silica film.

A system for mainly transferring various information of a newspaper, a magazine, an advertisement, and the like by dot data is provided. Data information provided from a newspaper company, publishing companies, and the like is converted into electronic press information via an electronic press producer 20. The electronic press information is dispatched from a center to an information vending machine through a satellite line or a terrestrial line. Dispatched press data is once accumulated to a recording unit in the information vending machine. When it is identified that an information fee has been paid by cash or a prepaid card, desired data in the information accumulated in the recording unit is written into a recording medium such as an IC card or the like of a consumer.

An image display device includes a main body having a display unit with a first display screen A and a display unit with a second display screen B and a link 56 for merging the two display screens to one. The two display units are opened and closed at the link so that the display screens are folded over each other for carrying like a book, and they are opened in a use mode to permit the recognition of the display image.
摘要:
Provided are a positive electrode for a lithium-sulfur secondary battery and a method of forming the same, the positive electrode being capable of maintaining battery characteristics such as a specific capacity and a cycling characteristic while achieving a high rate characteristic in particular when being applied to a lithium-sulfur secondary battery. A positive electrode of a lithium-sulfur secondary battery includes a positive electrode current collector and carbon nanotubes grown on a surface of the positive electrode current collector and oriented in a direction orthogonal to the surface. At least the surface of each of the carbon nanotubes is covered with sulfur with a certain interstice left between neighboring ones of the carbon nanotubes.
