| 20110230064 | ELECTRICAL CONNECTOR AND ASSEMBLY THEREOF - An electrical connector assembly includes an electrical connector, a chip located and a printed circuit board located at opposite sides of the anisoptropic conductive film. The electrical connector has an anisoptropic conductive film and a loading mechanism. The anisoptropic conductive film includes an adhesive and a number of conductive particles dispersed in the adhesive. The anisoptropic conductive film has conductivity only in a thicknesswise direction by pressing. The loading mechanism can exert pressure on the anisoptropic conductive film so that the chip and the printed circuit board electrically couples with each other. | 09-22-2011 |

| 20080307933 | Wrench rotatable in multiple orientations - A wrench structure rotatable in multiple orientations includes a head portion, an extension element, and a holding portion. The rear end of the head portion has a first protruding connection part. The extension element includes a front end having a first concave connection part in connection with the first protruding connection part and a rear end having a second protruding connection part. The first concave connection part has a first side and a second side connected by a bottom edge. A stopping device is provided at an appropriate position on the bottom edge. The holding portion includes a front end having a second concave connection part in connection with the second protruding connection part and a rear end. The second concave connection part has a first side and a second side connected by a bottom edge. A stopping device is provided at an appropriate position on the bottom edge. It fixes the second protruding connection part as it rotates to a desired orientation. Such a structure allows the wrench to rotate in different orientations. | 12-18-2008 |
| 20110041657 | FOLDABLE TOOL KIT HAVING A RATCHET POSITIONABLE IN MULTIPLE ORIENTATIONS - A foldable tool kit has a ratchet head, a wrench body, a bit holder, a plurality of bits and a gripping handle. A protruding column extends from the ratchet head and is jacketed by an extension rod. The wrench body has a U-shaped cross-section, and side walls of one end of the wrench body form securing plates between which the ratchet head is pivoted. The extension rod opens out from, or closes into, a first opening of the wrench body, and tap holes are provided on side walls of another end of the wrench body. One end of the bit holder has a pivot base, and the pivot base has a pair of first pivot portions corresponding to a pivot hole from two sides of the pivot base. The grip handle also has an inverted U-shaped cross-section and two sides of one end each respectively have a through hole. | 02-24-2011 |

| 20110050370 | HIGH ELECTROMAGNETIC TRANSMISSION COMPOSITE STRUCTURE - The invention discloses a high electromagnetic transmission composite structure for reducing the transmission loss of an electromagnetic wave. The high electromagnetic transmission composite structure includes a first composite structure layer, a second composite structure layer, and a first buffer layer. The first composite structure layer has a first thickness and a first dielectric constant. The second composite structure layer has a second thickness and a second dielectric constant. The first buffer is disposed between the first composite structure layer and the second composite structure layer and has a third thickness and a third dielectric constant. The transmission loss of the electromagnetism wave can be adjusted by adjusting the first thickness, the first dielectric constant, the second thickness, the second dielectric constant, the third thickness, and the third dielectric constant. | 03-03-2011 |

| 20080264772 | Method and apparatus for esterification - The method and apparatus for improving the esterification procedure, in particular for improving the esterification procedure to obtain an ester of low carbon number such as the ethyl acetate and the isopropyl acetate, are provided. By means of the provided method and apparatus, the conversion ratio of the esterification procedure is significantly increased and hence an ester product of a relatively high purity, up to the industrial specification, is obtained. | 10-30-2008 |
| 20090198083 | Method for manufacturing esters from acid and system thereof - A process for manufacturing esters from acid and alcohol and a system thereof are provided, wherein the system includes a reactive distillation column, a sidestream reactor packed with catalyst, and a decanter for conducting the method. The method is carried out by (a) extracting a first mixture of acid and alcohol from the reactive distillation column, for then feeding the first mixture to at least one sidestream reactor packed with catalyst to obtain a reaction product; (b) feeding the reaction product from the sidestream reactor to the reactive distillation column, allowing a second mixture of alcohol, ester and water to be separated from a top end of the reactive distillation column; (c) feeding the second mixture into the decanter to separate an organic phase from an aqueous phase; and (d) separating esters from the organic phase. The method and system allow the esters to be extracted without using a plurality of recovering columns and decanters, and are capable of improving packing/changing catalyst in a single reactive distillation column. | 08-06-2009 |
| 20090264674 | SYSTEM AND METHOD FOR PRODUCING DIESTER - The system and method for producing diester are provided. The system includes a first distillation unit reacting a dicarboxylic acid with an alcohol to produce a first gaseous mixture, a first cooling unit connected to the first distillation unit and cooling the first gaseous mixture into a first liquid mixture, a second distillation unit connected to the first cooling unit and separating the first liquid mixture into a second gaseous mixture and a second liquid mixture, and a liquid-liquid extraction unit connected to the second distillation unit and separating the second liquid mixture into an aqueous-rich mixture and an organic-rich mixture from which the diester is obtained. | 10-22-2009 |
