Abstract: A method for manufacturing a vehicle wheel includes: a casting process of manufacturing the wheel in a one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, wherein the one-piece body further includes a resonance chamber forming groove; a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove; a flow forming process of bending the forming end to be seated on the stepped part; a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other; a fine machining process of removing the temporary flange; and a sound-absorbing hole machining process of forming a sound-absorbing hole for communicating between the resonance chamber and an interior space of a tire in the forming end.

Abstract: In various embodiments, an antenna array may comprise a dielectric; a first patch antenna disposed on a first region of the dielectric; a second patch antenna disposed on a second region of the dielectric; and a ground layer including a first sub-ground layer in contact with a lower portion of the first region of the dielectric, a third sub-ground layer in contact with a lower portion of the second region of the dielectric, and a second sub-ground layer spaced apart from a lower portion between the first region and the second region of the dielectric.

Abstract: A security document control system and a control method thereof are disclosed. The system functions to automatically control a series of security operations including sensing security documents, storing all records with respect to check-out of security documents in a database, closing exit gates if illegal removal of security documents is judged, and informing a control center and security guards of the illegal removal of security documents so as to arrest an employee who attempts to illegally remove security documents.

Abstract: A golf ball surface is divided into faces of an icosidodecahedron consisting of 20 regular triangles and 12 regular pentagons, each of said 20 regular triangles is subdivided into 4 small regular triangles, each of said 12 regular pentagons is subdivided into 5 isosceles triangles, 6 dividing lines of the spherical surface occur when structured as above, and on the remaining 5 dividing lines except 1 mold parting line of 6 dividing lines are crossed the dimples, said dimples aren't crossed on the center of said regular triangles and pentagons, and said dimples intervals are arranged in a spaced circle on the basis of on the center of the respective regular triangles and pentagons.
