  • Patent number: 9699911
    Abstract: A process apparatus capable of pushing a panel-shaped object includes a process apparatus and at least one panel-shaped object. The process apparatus includes a carrying fixture and a separating fixture. The carrying fixture has a top surface and a bottom surface opposite to each other and has at least one positioning pillar. The separating fixture has a pushing portion. The panel-shaped object has at least one positioning hole and is carried on the top surface. The positioning pillar is inserted into the positioning hole to position the panel-shaped object. The pushing portion is adapted to move from the bottom surface toward the top surface and protrude out of the top surface, such that the panel-shaped object is pushed up by the pushing portion to be separated from the carrying fixture. In addition, a process method adapted to the process apparatus capable of pushing a panel-shaped object is also provided.

  • Publication number: 20170133793
    Abstract: A bidirectional access portable flash drive includes a casing, which defines therein a receiving space that receives a circuit board mounted therein. The circuit board has a surface on which a memory unit is mounted. The casing has an end to which a double-side pluggable micro-USB connector is mounted. The double-side pluggable micro-USB connector includes a frame and a plate mounted at a predetermined location in the frame. The plate has two surfaces each including a plurality of conductor elements mounted thereon. The plate has two ends at which at least one fixing element is mounted. The memory unit enables effective access and storage of data and the double-side pluggable micro-USB connector provides functions of double-side plugging and protection to achieve an effect of convenient transmission, access, and use of data.

  • Patent number: 9591794
    Abstract: The disclosure provides a feeder system, for providing multiple materials from a tube, including a transportation platform and a material guiding carrier. The material guiding carrier is mounted on the transportation platform. The material guiding carrier includes a material input portion and a material output portion. A material output opening of the tube is located at the material input portion. The materials from the tube are conveyed to the material guiding carrier by the transportation platform. At least two guiding members are mounted on the material guiding carrier for matching the tube in an adjustable manner to guide the materials from the material input portion to the material output portion along a material feeding direction. The material feeding direction and an arrangement of the at least two guiding members are parallel to each other.
