  • Patent number: 10106424
    Abstract: A method of preparing silicon using silica includes placing silica in a reaction chamber; adding a reducing agent into the reaction chamber; feeding a material for impact into the reaction chamber and sealing the reaction chamber; and reducing the silica to silicon by allowing the material for impact to generate a physical impact inside the reaction chamber. The preparation method of silicon using silica does not employ a high-temperature high-pressure process and provides a preparation method of silicon by which the porous structure of the silica before a reduction reaction is maintained within the silicon even after the reaction.

  • Patent number: 8811609
    Abstract: An information protection system includes a mobile terminal and an encryption module. The mobile terminal requests a key sequence by transmitting a message including a Personal Identification Number (PIN) number input by a user, and encrypts or decrypts one or more communication signals, including voice signals and data signals, based on the key sequence when the key sequence is received. The encryption module is connected to the mobile terminal. The encryption module encrypts a security key using the identifier and the PIN number of the mobile terminal, decrypts the encrypted security when requested by the mobile terminal, and transmits the key sequence generated based on the decrypted security key to the mobile terminal.

  • Patent number: 7488011
    Abstract: A method and apparatus for winding and knotting a thread around a sewing thread of a button for clothes so that a gap between the button and a suit, on which the button is sewn, is maintained. The thread, which is twisted at least twice, passes over and winds around the sewing thread, thereby forming firm knots of the thread around the sewing thread and preventing the knots from being disentangled. Since guiding means accurately and reliably guides the thread to pass over the sewing thread, and the knot-guiding means and the thread take-up means of the apparatus are simultaneously operated by a single driving means, the invention performs firm and effective winding of the thread around the sewing thread and reduces production costs and energy consumption rate of the apparatus, and reduces failure rate, thereby improving reliability of winding and knotting the thread around the sewing thread.
