Granted: 2005-01-11
Abstract: A financial information input method using a symmetric key security algorithm and a mobile communications commercial transaction system using the same encrypts financial information such as a customer's identification number and a valid date with a symmetric key algorithm by use of an electronic wallet administration number of a customer's terminal used as an encryption key at the time of applying an issuance of a card, and directly inputs the encrypted financial information into a customer's electronic wallet terminal or inputs the same via a communications network. In the case that a commercial transaction settlement is accomplished with a mobile communications terminal in which the encrypted financial information is stored, his or her own electronic wallet administration number is input so that the encrypted financial information and the administration number are optically transmitted to a POS terminal/card inquiry machine of an affiliated shop. The POS terminal/card inquiry machine which has received the encrypted financial information and administration number uses the received electronic wallet administration number and decodes the encrypted financial information with the administration number. Thus, although unauthorized person knows an encryption algorithm unless a customer's electronic wallet administration number is exposed illegally, customer's financial information cannot be used. That is, an effect of fundamentally preventing customer's financial information from being illegally copied can be provided.

Title: Filtration device
Inventor: TSUIHIJI MOTOYUKI
IPC: B01D29/15
Filed: 2002-10-15
Granted: 2004-01-11
Abstract: In conventional arts, there has been no effective method for filtering the drainage occurred in mechanical processes, such as CMP. This is due to that the drainage is under a colloid solution state since the grinding particles contained within the CMP slurry are fine particles. In the present invention, which provides a filtration device, the drainage containing the fine particles of the colloid solution is introduced into a tank 50, circulated, and filtered by means of a second filter 2, which is construed by a gel film being disposed on the surface of a first filter 1 by suction. The suction pressure while filtering is extremely weakened in order to maintain filterability while delaying the blockage of the second filter 2. Further, the gel film of the second filter 2 sucked on the surface of a first filter 1 is capable of departing with ease while stopping the suction, and a filtration device capable of re-continuing the filtration is thus realized.
