20080280029Surface treatment method for solder joint - A surface treatment method for solder joint employs alkali buffer solution dipping the solder joint and the alkali buffer solution reacts with the solder joint thus yielding a passive layer. As the resultant passive layer forms on the surface of the solder joint, thereby prevents further corrosion and dissolution during aqueous cleaning or water dipping thereafter. In addition, the passive layer ensures a good appearance with maximum protection of the solder joint and also provides a sound reliability and a high testability of a finished electronic product equipped with the solder joint.11-13-2008

20110104986Mark-free wire fabric straps - A mark-free fabric strap wire casing. The casing is provided with a cushion B which is composed of erect fine hairs C for relieving the stress generated by the bra wire on skin. With simple structure, the present invention which is used as the casing for the wire used in female underwear can be manufactured with high production efficiency and suitable for the production automation. Because the fabric strap itself is provided with a cushion composed of erect fine hairs, it has a softer feel when in contact with skin and relieves the pressure feel generated by the wire within the underwear on skin. It reduces the wire impression mark left under the breasts after wearing it. The wire can be embedded without causing much embossment, thereby enchaining visual appearance of the underwear article.05-05-2011
20110151155Fabric Strap with Multi-Layer Structure For Air-Cushion Effect And Uses Thereof In Underwear - The present utility model relates to the technical field of fabric straps, more particularly, it relates to a fabric strap with a multi-layer structure. Said fabric strap itself is integrally interwoven by the fabric with at least a double-layer structure. It is characterized in that: there are at least two layers fabric connecting up-and-down with one or more groups of yarn according to a certain weave structure. Said one or more groups of yarn not only can form an air cushion with erect fine hairs, but also can increase anti-bursting strength of the fabric. When the present utility model is applied to the shoulder straps of underwear, it can effectively relieve the stress on the skin generated by the fabric straps and increase comfort of underwear; when applied to the underwear wire casing, it can not only greatly increase anti-bursting strength, but also relieve the stress on female breasts generated by wire with formed cushion, thus preventing uncomfortable stress on the points of contact on skin after wearing said underwear. Impressions on the skin can be avoided and the comfort and safety of underwear can be improved.06-23-2011
20110237158VELVET WIRE CASING AND UNDERWEAR - A velvet wire casing for containing the steel wire used as a bra support in underclothing. It has a woven casing main body on which there are erect down-like soft fine feathers or hairs, which are integratedly woven into the main body when the main body is fabricated.09-29-2011

20090288595DEVICE WITH REVOLVING SHAFTS FOR TRANSVERSELY SOAKING PREPREG - The present invention pertains to a device with revolving shafts for transversely soaking prepreg which comprises a basin filled with resin glue and revolving shafts disposed therein for laterally transporting a prepreg from the bottom side of the basin to the top side thereof. By means of the transverse route of the prepreg conducted by the revolving shafts, the time of soaking the prepreg in the basin is extended so as to reduce bubbles existed in the prepreg via fully immersing the resin glue throughout the prepreg and further increase the composite quality of the copper-clad laminate and the reliability of the metal resistant ion. Therefore, the present invention facilely gets acclimated to the industry without adding more equipment.11-26-2009
20090291223METHOD FOR TRANSVERSELY SOAKING PREPREG - The present invention pertains to a method for transversely soaking prepreg applied to the copper-clad laminate which initially supplies a prepreg to a bottom side of a basin filled with resin glue, and thence laterally transports the prepreg from the bottom side of the basin toward the top side thereof via guidances of revolving shafts disposed inside the basin. By means of the transverse route of the prepreg conducted by the revolving shafts, the time of soaking the prepreg in the basin is extended so as to reduce bubbles existed in the prepreg via fully immersing the resin glue throughout the prepreg and further increase the composite quality of the copper-clad laminate and the reliability of the metal resistant ion. Therefore, the present invention facilely gets acclimated to the industry without adding more equipment.11-26-2009
20090292050Kind of Prepolymer and Its Product-Thermosetting Resins Composite - The invention provides a kind of prepolymer with 4-(N-maleimide phenyl)Ether (MPGE) epoxy resin and 4,4′-diphenylmethane-amino-di-malays polyimide (BMI) as reactants, with free radical initiator leading to reaction in solvents, and adding inhibitor after reaction, with the mole ratio of 0.05-0.5 for BMI and MPGE; the initiator usage is 0.01%-0.15% of mole total for reactant monomers; the solvent usage is 50%-70% of the total weight of the reactants; the inhibitor usage is half to double of mole amount of the initiator used. This kind of prepolymer can be used to produce high-performance thermosetting resin composition corresponding to the packaging requirements for electronic components and Integrated Circuits (IC).11-26-2009
