  • Publication number: 20060216463
    Abstract: A method of manufacturing a pleated product capable of partially pleating a fabric so that boundaries between pleat portions and non-pleat portions can be conspicuous and a fabric for the pleated product used for the method. In this method, a part of the fabric for the pleated product (1) in which one of warp (2) and weft (3) is formed of easy-to-pleat yarn and the other formed of hard-to-pleat yarn is folded along a folding line (4) tilted relative to the warp (2) and the weft (3), the fabric (1) is pleated up to the folding line (4) in the passing direction of the warp (2) or the weft (3), and the fabric (1) is unfolded and washed. Effective pleats are formed only in the passing direction of the easy-to-pleat yarn on a plane on one side of the folded portion and not formed in the passing direction of the hard-to-pleat yarn on a plane on the other side of the folded portion.

  • Patent number: 6253997
    Abstract: A user interface unit transmits a user's instruction to a main control unit. The main control unit generates control data according to the user's instruction and an instruction from a host and transmits the control data to a cash input/output unit. A cash output control unit in the cash input/output unit withdraws cash from a safe based on the control data and outputs the cash. The encryption process unit of the main control unit encrypts the control data. The encryption process unit of the cash input/output unit decrypts the encryption data encrypted by the encryption process unit of the main control unit and reproduces the original control data. Mutual authorization is performed between the main control unit and cash input/output unit.

  • Patent number: 5097115
    Abstract: A transaction authentication system comprises a terminal, a first memory and an IC card which is detachably loaded into the terminal. The terminal supplies at least transaction data which is related to a transaction a designated storage region in a second memory stores the transaction data to the IC card when the IC card accesses to a service via the terminal. A second processor of the IC card writes the transaction data received from the terminal in the designated storage region of the second memory and generates a vertified data which is renewed every time the transaction data is written into the second memory. The verified data has a value in conformance with a predetermined generating algorithm and is stored in the second memory and also supplied to the terminal.
