Abstract: An automatic image-capturing system is used for capturing an image and transmitting the image to a remote device. The automatic image-capturing system includes a photography module for capturing the image; a storage module for storing the image captured by the photography module; a transmission module for receiving a control instruction sent by the remote device; a master core module for making the photography module to capture the image based on the control instruction, and segmenting the image into a plurality of files and segmenting the files into a plurality of packets to be transmitted to the remote device by the transmission module, and a slave core module for monitoring the operations of the master core module to turn off and restart the master core module when there is an abnormal operation in the master core module.

Abstract: The present invention pertains to a method for cold forging high strength fastener with austenitic 300 series material comprising the procedures of initially preparing a raw austenitic shaft and then proceeding through a cold forging method to reduce its diameter for thereafter generating a preliminary shank, which can undertake above ½ force more than the raw shaft; further passing through the following formations of the head, the drilling portion and threads in sequence to build an integral fastener. Thus, the entire cold forging facilitates to fabricate the fastener with high strength and hardness by lower manufacturing cost and with effective corrosion resistance, so as to firmly drill the fastener into objects and increase the screwing security.

Abstract: The present invention pertains to a screw with a removable tip section comprising a shank and a tip section; wherein the shank has a first threaded section consisted of an upper and a lower threaded sections and a recess defined at the surface of an end face. Furthermore, the tip section includes a second threaded section disposed thereon and an insertion having a coincident shape with the recess. By means of those threaded sections with different outer diameters, the screw is smoothly driven into the metal objects without being interfered in drilling and steadily fixed therein without swing after screwing; After screwing in, the tip section is alternatively removed from the shank by a wrench to be put into the recess to tighten or loosen the screw so as to increase the convenience of using.

Abstract: A screw assembly mainly includes a shank; the shank engaged a recess in the shank; said recess inserted into a tip section, and the tip section inserted into the shank. Besides, the tip section has second threads, which connected to first threads. And the second threads have the same pitch with the first threads so that the first threads easily screwed into a metal objects by rotating the tip section. The second threads with the first threads rotated into the metal object smoothly so that reduces the first threads damaged, and adjusted the screw assembly by engaged a wrench with the recess from underside of the metal objects.

Abstract: A shoe sole air cushion includes a hollow main body defining an air chamber. The main body includes bottom and top walls, and a peripheral wall connected between the bottom and top walls. The bottom wall includes a plurality of lower pins projecting upwardly from an inner surface of the bottom wall. The top wall includes a plurality of upper pins projecting downwardly from an inner surface of the top wall. The upper and lower pins respectively have tapered ends. The tapered ends of the upper pins are connected respectively to the tapered ends of the lower pins.
