20120088897 | EXTREME LOW FORMALDEHYDE EMISSION UF RESIN WITH A NOVEL STRUCTURE AND ITS PREPARATION - The present invention relates to an extreme low formaldehyde emission UF resin with a novel structure, and a process for its preparation. This UF resin is produced from formaldehyde, urea, a long chain multi-aldehyde prepolymer, and some modifiers. Its process follows three steps: weak caustic, weak acid and weak caustic. By using this prepolymer, the modified UF resin has stable alkyl ether structure, and the residual aldehyde groups on the UF polymer chain could accelerate cross-linking instead of dissociative formaldehyde. The UF resin made from this invention has extreme low dissociative formaldehyde and simple technology. The boards produced from this resin have good physical performance and water resistance. Moreover, the formaldehyde emission of the boards is extreme low, achieving Japan F⋆⋆⋆⋆ grade, the average emission value≦0.3 mg/L. | 04-12-2012 |

20140293524 | EJECTING APPARATUS AND ELECTRONIC DEVICE EMPLOYING THE EJECTING APPARATUS - An electronic device comprises a main body, a plurality of I/O interfaces, and an ejecting apparatus. The ejecting apparatus is mounted on the main body and comprises an enclosure, a supporting member received in the enclosure, a carrier secured on the supporting member to support the I/O interfaces, a first driving unit, and a second driving unit. The first driving unit drives the carrier to slide along a first direction, and the second driving unit drives the carrier to slide along a second direction opposite to the first direction. When the I/O interfaces are exposed out of the enclosure, the first force is larger than the second force. When the carrier is operated to slide to a position where the second force is larger than the first force, the I/O interfaces are driven to be received in the enclosure. | 10-02-2014 |
