Abstract: The present invention relates to a white, porous, single-layer polyester film comprising a polyester resin, particles of a noncrystalline polymer which has a heat deformation temperature higher than the temperature of the drawing process of said film by at least 10° C. and is not miscible with the polyester resin, inorganic particles and a whitening agent. The inventive single layer film has sufficient process stability as well as good optical properties, and thus is useful as a film for use in printing, labeling, electronics and display applications.

Abstract: A method for an automatic document feeder which can control the feeding of a following sheet such that the following sheet can be delayed for a predetermined time when the interval between sheets is shortened, thereby maintaining a constant interval between the sheets. The method and apparatus comprises a paper feeding roller, an arranging roller for arranging a front end of a document being fed by the paper feeding roller and for transferring the document, and an arranging sensor disposed at a front portion of the arranging roller to detect whether the document is being transferred. The arranging sensor detects a rear end of a previous sheet and a front end of a next sheet, and an operation of the arranging roller is controlled using a time interval between the previous sheet and the next sheet.

Abstract: A portable communication device includes a main housing, a folding housing coupled to the main housing by a hinge unit to rotate about a hinge axis, and a flexible display unit that is drawn out from the main housing to open its display screen when the folding housing unfolds.
