| 20080227566 | TITANIUM ALLOY FOR MAKING A GOLF CLUB HEAD - A titanium alloy for making a gold club head includes aluminum in an amount ranging from 7.8 to 10.0 wt %, molybdenum in an amount of greater than 0 wt % and not more than 2 wt %, vanadium in an amount of greater than 0 wt % and not more than 2 wt %, silicon in an amount of greater than 0 wt % and not more than 2 wt %, and a balance of titanium, based on a total weight of the alloy. | 09-18-2008 |
| 20080307631 | METHOD FOR FORMING A PATTERN ON A GOLF CLUB HEAD - A method for forming a pattern on a golf club head includes the steps of forming at least one primer layer on the golf club head, and engraving the primer layer using a laser beam to form the pattern on the primer layer. The primer layer has a dark color, and a light-transmissive protecting layer is optionally applied on the primer layer after engraving. | 12-18-2008 |
| 20090042667 | Golf club head - A golf club head includes a shell, a covering plate, and a male-and-female engagement unit. The shell includes an inner surface, an outer surface, an assembling hole extending through the inner and outer surfaces, a bounding edge bounding the assembling hole, and a flange projecting inwardly from the inner surface and the bounding edge and extending toward the assembling hole. The flange has a shoulder face that has a depth from the outer surface and that is adjacent to the bounding edge. The shoulder face extends in full length of the bounding edge. The covering plate is inserted into the assembling hole and contacts the shoulder face. The male-and-female engagement unit is provided on and interengages the covering plate and the flange. | 02-12-2009 |
| 20090137336 | Golf Club - A golf club includes a shaft body, a head body connected to the shaft body, and a thermochromic portion provided on at least one of the shaft body and the head body and including a thermochromic blend. The thermochromic blend is made by blending a coating material or a molding material with a thermochromic material. | 05-28-2009 |
| 20100290944 | TITANIUM ALLOY FOR MAKING A GOLF CLUB HEAD - A titanium alloy for making a golf club head includes aluminum in an amount of greater than 8.0 wt % and not more than 10.0 wt %, molybdenum in an amount of greater than 0 wt % and not more than 2 wt %, vanadium in an amount of greater than 0 wt % and not more than 2 wt %, silicon in an amount of greater than 0 wt % and not more than 2 wt %, and a balance of titanium, based on a total weight of the alloy. A golf club head made by the titanium alloy is also disclosed. | 11-18-2010 |

| 20090145333 | Method for dispersing pigment in solvent - A method for dispersing a pigment in a solvent comprises mixing the pigment in a nanoscale with clay in a layered or platelet form and mixing the resultant mixture with the solvent. The method is based on geometric inhomogeneity and mutually exclusive aggregation. The layered or platelet clay having a high aspect ratio is provided to hinder aggregation of the pigment nanoparticles. The pigment nanoparticles can be stably dispersed in a matrix containing an organic solvent and water without aggregation again. | 06-11-2009 |
| 20090146107 | INORGANIC/ORGANIC DISPERSANT AND APPLICATION THEREOF - The present invention discloses an inorganic/organic mixed component (I/O) dispersant and applications thereof, which is primarily applied to dispersing nanoparticles of metal oxides. The I/O dispersant of the present invention can be a composite of inorganic clay and an organic surfactant, a composite of inorganic clay and polyoxyalkylene-amine, or a composite of inorganic clay, polyisobutylene succinic anhydride (PIB-SA) and hydrochloric acid salt or tetraalkyl quaternary salt of polyoxyalkylene-amine, or fatty amines. By mixing with the I/O dispersant of the present invention, nanoparticles of a metal oxide can be uniformly dispersed without aggregation particularly at high solid content. The dispersion has a lower viscosity and is relatively stable in storage even at high temperature. | 06-11-2009 |
| 20090149583 | POLYMERIC POLYAMINES AND METHOD FOR STABILIZING SILVER NANOPARTICLE BY EMPLOYING THE SAME - The present invention discloses a polymeric polyamine which can be produced by polymerizing polyoxyalkylene-amine and a linker. The linker can be anhydride, carboxylic acid, epoxy, isocyanate or poly(styrene-co-maleic anhydride) copolymers (SMA). The present invention also discloses a method for stabilizing the Ag nanoparticles with polymeric polyamine. The polymeric polyamine serving as a stabilizer or dispersant is mixed with a water solution of silver salt and then a reducer is provided to reduce the silver ions and form an organic or a water solution of Ag nanoparticles. Water or solvent of this solution can be further removed through a heating, freezing or decompression process, and thus solid content of the solution can be increased. The concentrated solution also can be diluted to obtain a stable dispersion without aggregation. | 06-11-2009 |
| 20100274036 | ORGANIC/INORGANIC COMPOSITIVE DISPERSANT INCLUDING INORGANIC CLAY AND ORGANIC SURFACTANT - The present invention provides an organic/inorganic compositive dispersant and a method for producing the same. The compositive dispersant comprises a complex of inorganic clay and an organic surfactant. The compositive dispersant is produced by reacting inorganic clay with the organic surfactant in a solvent to generate a complex. The inorganic clay is layered or platelet. The organic surfactant is an anionic surfactant such as alkyl sulfates, a nonionic surfactant such as octylphenol polyethoxylate and polyoxyethylene alkyl ether, or a cationic surfactant such as fatty (C12˜C32) quaternary ammonium salts and fatty (C12˜C32) quaternary ammonium chlorides. | 10-28-2010 |
