  • Patent number: 12365503
    Abstract: A cotton stuffing machine includes a roller conveyance device, a rotation device, an upward pushing device, and a downward pressing device. The roller conveyance device inputs cotton and presses and pulls the cotton to deliver a cotton section. The rotation device includes a plurality of rotation arms. Each rotation arm has a holding barrel on two ends thereof, and undergoes a 180-degree rotation displacement between a feeding position and an outputting position. The upward pushing device is disposed beneath the feeding position for pushing the cotton section upward into the holding barrel. The downward pressing device is disposed above the outputting position for pushing out the cotton section and inserting it into the bottle. Thus, the present invention improves the efficiency of stuffing operation for stuffing the cotton into the bottles.

  • Patent number: 10545615
    Abstract: A touch device including a touch screen, a first input device and a processor is provided. At a first start time, when the first input device touches on the touch screen with a first touch area at a first position, the touch screen generates a first event, and the first input device transmits a first signal to the touch screen. The processor is coupled to the touch screen. When the touch screen receives the first signal during a pre-determined period from the first start time and the first touch area is larger than a first area threshold, the processor determines that the first event belongs to the first input device and that the first position is a start position of the first input device.

  • Publication number: 20140104513
    Abstract: A method of fabricating an electronic apparatus having an active region and a peripheral region surrounding the active region is described. A first main device and a second main device are provided. An optical clear liquid adhesive (OCLA) is applied between the first main device and the second main device and within the active region. A photo-mask having a transparent region and an opaque region is provided above the second main device, and the transparent region corresponds to the peripheral region. An OCLA diffusion process is performed such that the OCLA diffuses from the active region to the peripheral region. During the OCLA diffusion process, a first irradiating process with the photo-mask is performed, such that the OCLA diffusing to the peripheral region is partially cured. After removing the photo-mask, a second irradiating process is performed, such that the OCLA is completely cured.
