| 20100072433 | RESIN PACKAGE AND PRODUCTION METHOD THEREOF - The method for producing a resin package according to the present invention includes a step of forming a copper oxide layer by oxidizing the surface of a lead frame in which at least the surface is made of copper, and a step of forming a resin package main unit by allowing a resin to adhere to the copper oxide layer on the lead frame surface by resin molding for package, and then removing a predetermined area of the copper oxide layer with an acidic solution. | 03-25-2010 |
| 20100227175 | METHOD FOR FUSION BONDING MOLDED ARTICLE OF LIQUID CRYSTALLINE POLYMER AND GLASS SUBSTRATE TO EACH OTHER AND COMPOSITE ARTICLE OBTAINED BY THE METHOD - A method for fusion bonding a molded article of a liquid crystalline polymer and a glass substrate to each other, comprising bringing the molded article into contact with the glass substrate; and setting the temperature of a contact portion of the molded article in contact with the glass substrate, at a predetermined temperature, wherein when the predetermined temperature of the contact portion is represented by T | 09-09-2010 |
| 20110128743 | METHOD FOR PRODUCING LIQUID CRYSTALLINE POLYESTER, LIQUID CRYSTALLINE POLYESTER COMPOSITION, REFLECTOR PLATE AND LIGHT-EMITTING DEVICE - The present invention provides a method for producing a liquid crystalline polyester, the method comprising the steps of reacting monomers to obtain a polycondensate corresponding thereto, granulating the polycondensate to obtain a granule, and subjecting the granule to solid-phase polymerization to obtain a liquid crystalline polyester, wherein the content of iron in the granule to be subjected to the step (C) is 5 ppm by weight or less. According to the present invention, a liquid crystalline polyester having high whiteness and excellent heat resistance can be produced with satisfactory operability. | 06-02-2011 |
| 20110189454 | LIQUID CRYSTALLINE POLYESTER COMPOSITION, METHOD FOR PRODUCING THE SAME, AND CONNECTOR - The present invention provides a composition comprising a liquid crystalline polyester, a plate-like filler and a carbon black having a number average particle size of more than 20 nm and 45 nm or less. The composition is less likely to cause blister even at a high temperature. | 08-04-2011 |
| 20110189455 | METHOD FOR PRODUCING LIQUID CRYSTALLINE POLYESTER COMPOSITION, AND CONNECTOR - The present invention provides a method for producing a composition, the method feeding a liquid crystalline polyester and mica into an extruder having a vent section, and melt-kneading them under the conditions where the degree of pressure reduction of the vent section is −0.06 MPa or less in terms of a gauge pressure. The production method can provide a composition containing a liquid crystalline polyester and mica, the composition being less likely to cause blister event at a high temperature. | 08-04-2011 |
| 20110245432 | METHOD FOR PRODUCING THERMOPLASTIC RESIN COMPOSITION - The present invention provides a method for producing a thermoplastic resin composition, the method comprising a step of melt-kneading 5 to 55 parts by weight of an aromatic polycarbonate resin and 95 to 45 parts by weight of an aromatic polysulfone resin while shearing at a sharing speed of 1,000 to 9,000/sec. By the method, a thermoplastic resin composition excellent heat resistance and transparency can be obtained. | 10-06-2011 |
| 20120025421 | METHOD FOR PRODUCING LIQUID CRYSTAL POLYESTER COMPOSITION - The present invention provides a method for producing a liquid crystal polyester composition, the method comprising feeding a liquid crystal polyester and a polyhydric alcohol fatty acid ester into an extruder having a vent portion, followed by melt-kneading in a state where the degree of decompression of the vent portion is −0.06 MPa or less in terms of a gauge pressure. The composition obtained by the method can provide a molded article having a thin wall portion and complicated shape. | 02-02-2012 |
