  • Patent number: 12222160
    Abstract: A material processing apparatus is disclosed. This material processing apparatus is particularly developed to utilize a quasi-traveling microwave to conduct heat treatment for a thread-type article like fiber, silk, artificial fiber, and artificial silk. The material processing apparatus comprises a primary waveguide tube, a microwave blocking plate, a secondary waveguide tube, and at least one microwave absorbing member disposed of in the primary waveguide tube. By such design, a microwave source supplies a microwave to the secondary waveguide tube and the primary waveguide tube, such that the microwave travels in the two waveguide tubes so as to become a quasi-traveling microwave. Therefore, in the case of a thread-type article being be fed into the primary waveguide tube via the secondary waveguide tube by a thread-type article transferring mechanism, the thread-type article is steadily and evenly heated by the quasi-traveling microwave in the two waveguide tubes.

  • Publication number: 20240167964
    Abstract: An automatic food inspection device includes a feeding container, a track conveying device, a transparent track and an image capture module. The feeding container is used for accommodating the objects to be tested, the track conveying device is connected to the feeding container for conveying the objects to be tested, and the transparent track is separated with the track conveying device to further convey the objects to be tested. In addition, the image capture module is located adjacent to the track conveying device and the transparent track to capture images of the objects to be tested to judge the quality of the objects to be tested. In addition, the image capture module includes a plurality of image sensors, and a plurality of lighting devices to illuminate the objects to be tested while passing through the transparent track.

  • Patent number: 9958755
    Abstract: An electronic device includes a casing, a supporting member, a sliding lid and an elastic member. The casing has a window. The supporting member is in the casing and has a through hole. The sliding lid is slidably disposed on the supporting member so that the sliding lid is slidable between an opened position and a closed position. The through hole is connected to the window when the sliding lid is located at the opened position, and the sliding lid is located between the through hole and the window when the sliding lid is located at the closed position. The elastic member is located on the same side of the sliding lid and the supporting member. One end of the elastic member is disposed on the sliding lid, and another end of the elastic member is disposed on the supporting member.
