  • Publication number: 20180267570
    Abstract: A portable electronic device includes a host module having a housing with an accommodation space, a display module and a lift structure. The display module is pivotally connected to the housing by a shaft. The lift structure includes a bottom cover covering the accommodation space, a swing member and a follower member. The bottom cover includes an abutment portion including an abutment surface and located on an end surface of the bottom cover adjacent to the accommodation space. The swing member is in the accommodation space and connected to the shaft. The swing member moves with the display module. The follower member connects to the swing member and contacts the abutment surface. The follower member moves in a first direction according to swinging of the swing member, therefore the follower member abuts against the abutment surface and the bottom cover moves in a second direction to lift up the housing.

  • Publication number: 20180094091
    Abstract: Provided is a method of preparing a powdery diacetal clarifying agent, which comprises mixing an aromatic aldehyde, a polyol, and an acid catalyst in an organic polar solvent, adding a hydrogenating agent and an inorganic silicon-containing agent into the foregoing mixture, and filtering the mixture. The powdery diacetal clarifying agent prepared by the method can have excellent flowability, dispersability, thermal resistance, and color stability. Accordingly, the powdery diacetal clarifying agent does not release stinking odor and incur yellowing at high temperature, allowing the plastic articles to have improved appearance and visual appeal.

  • Patent number: 9853349
    Abstract: An electronic device includes an operation body, a frame and an antenna. The frame encloses a lateral side of the operation body. The antenna is disposed within the frame, and partially exposed outside the frame. The antenna is electrically connected with the operation body to provide a wireless communication function. A wireless communication interference source is disposed within the operation body, or the operation body contains a metallic material. Since the operation body is enclosed by the frame, the frame can protect operation body and prevent collision of the operation body. Moreover, since the antenna is located outside the operation body, the antenna is away from the interference source that is disposed within the operation body. Consequently, the wireless communication efficiency is enhanced, and the inner space of the operation body is saved.
