Abstract: A cathode for a lithium secondary battery includes a cathode current collector, and a cathode active material layer formed on the cathode current collector. The cathode active material layer includes cathode active material particles. The cathode active material particles include a lithium metal oxide particle containing nickel and having a mole fraction of cobalt of 0.02 or less among all elements except lithium and oxygen.

Abstract: Provided is an eco-friendly cosmetic container including: a lower container having a cosmetic material accommodation dish seating portion; an upper container open and closed with respect to the lower container by means of a hinge coupling structure; a cosmetic material accommodation dish seated onto the cosmetic material accommodation dish seating portion; and an intermediate support adapted to be rotatingly locked onto the lower container and released from the locked state over a given region thereof onto and from the lower container to separably fix the cosmetic material accommodation dish to the lower container.

Abstract: A stick type cosmetic container capable of depleting a remaining amount of cosmetics is described. The cosmetic holder has raising and lowering ribs coupled to raising and lowering guide grooves of a protection tubular body, allowing cosmetics to appear and disappear in a proper length. One or more engaging ribs are formed in a stepped shape in the cosmetic holder. A stopper is provided on opposite portions of a flat second side outer circumferential surface of the raising and lowering supporting part and configured to be mutually caught by a lower end of the engagement rib to limit the upward movement of the cosmetics. The cosmetic holder is separably engaged to a tubular body through one or more engagement ribs. The tubular body is configured to be raised independently secondarily while being released from an engagement force from the engagement rib of the cosmetic holder.

Abstract: A transparent film having improved lighting performance, and a manufacturing method therefor are disclosed. According to a preferable embodiment of the present invention, the transparent film having improved lighting performance has a plurality of transmission and refraction parts formed at predetermined intervals on the surface of a support film, a cross-section of each of the transmission and refraction parts comprises a flat part, which has a predetermined height from the planar surface of the support film, and an inclined part extended from one end of the flat part to the plane of the support film, and the flat part is bonded to a glass window by an adhesive. Sunlight directly entering through the glass window is refracted and then is directed toward the bottom surface or is reflected at the inclined part and then is directed toward the ceiling, thereby entering deeply into an indoor place, and thus lighting effects are improved.

Abstract: The present invention provides an improved process for preparing a highly water absorbent resin having a superior suction power and excellent gel strength, which consists essentially of:(1) neutralizing acrylic acid to a neutralization degree ranging from 50 to 100% based on the total number of moles of the acid employed and polymerizing it by a reverse phase suspension polymerization to provide a neutralized polymer;(2) dehydrating the polymer until its water content reaches 25% by weight or less based on the weight of the polymer through an azeotropic distillation thereof in the presence of a lipophilic solvent;(3) crosslinking the dehydrated polymer in the presence of a hydrophilic crosslinking agent containing at least two epoxy groups in an amount ranging from 0.05 to 5.0% by weight and water added in an amount ranging from 7.0 to 25.
