Abstract: A positive electrode active material particle includes a core that contains lithium cobalt oxide represented by the following Chemical Formula LiaCo(1-x)MxO2-yAy and a shell that is coated on the surface of the core and contains composite metal oxide of a metal with an oxidation number of +2 and a metal with an oxidation number of +3. In particular, M is at least one selected from the group consisting of Ti, Mg, Zn, Si, Al, Zr, V, Mn, Nb and Ni. A is oxygen-substitutional halogen and 1.00?a?1.05, 0?x?0.05, and 0?y?0.001.

Abstract: Disclosed is an anti-weed sheet manufactured by forming webs. The web is formed of polyolefin-based staple fibers which are at least one selected from the group consisting of polyethylene staple fibers, polypropylene staple fibers, and polyisobutylene staple fibers. The sheet is bonded integrally by the needle punching by forming the webs, and the needle punching is performed in the order of pre-needle punching, low-speed needle punching, high-speed needle punching and low-speed needle punching to uniformly bridging the surface and the inside of the formed webs and improve a binding force. At least one surface of the sheet is modified by heat treatment through hot air or a heating drum.

Abstract: The present invention provides glasses having side shields, which include glasses bodies and side shields, each of the glasses bodies having a double hinged structure by means of a hinged portion and an elastically hinged portion formed at each of temples, each of the side shields having a movement space formed in such a way that one side of the side shield is inclined outwardly, thereby enhancing a feeling of wearing, preventing a change in shape of the temples when the temples are spread outwardly by an external force, and restoring the temples to their original positions in safe.

Abstract: A structure for fixing a side shield of glasses is disclosed, in which a glasses side shield can be easily detachably fixed at a glasses leg, and a shied shield can be protected from damages when attaching or detaching the side shield, with the glasses side shields being engaged between the left and right legs of glasses for thereby protecting user's eyes from being damaged by foreign substances which may be inputted between the glasses legs and a glasses body. The structure for fixing a side shield of glasses is characterized in that the fixture has a step portion protruded from a lower side end by a certain length with the fixture being inserted into the through hole of both sides through the opening of the side shield, and a curvature portion is formed at an upper side of the step portion, and the step portion of the fixture is tightly inserted into the through hole of the side shield, and a straight line shaped or cross shaped driver insertion groove is formed at an upper surface of the fixture.

Abstract: The present invention relates to a fixing structure of a side shield for glasses wherein a side shield installed in glasses legs, comprising a through hole formed in inner upper and lower portions of a rear end of a side shield surrounding the glasses legs, and a fixture having an elastic piece in the interior of the same and a hook part in the upper and lower sides of a front end wherein said fixture is inserted through an opening of the side shield, and the hook part of the fixture is engaged to the though hole, and the elastic piece of the fixture is elastically closely contacted with the glasses legs. In the present invention, the size of the fixture is large, and the hook part of the fixture is inserted into the through hole formed in the side shield. Therefore, anyone can easily insert the fixture for thereby achieving a convenient assembling work, and the side shield is easily fixed to the glasses legs.

Abstract: The present invention relates to a structure for fixing a side shield for glasses. In the present invention, the structure for fixing a side shield for glasses according to the present invention is capable of easily installing a side shield based on a work that a bolt is engaged to a hinge portion of the connection member and the glasses leg, namely, a work that the glasses leg is rotatably engaged to the connection member, by improving a bolt which hinge-engages the glasses leg without using an additional element. Therefore, in the present invention, it is possible to easily enhance a productivity by simply assembling the side shield to the glasses.
