Abstract: An identification information transmitter encrypts identification information for identifying a person or an object using an encryption key, transmits the encrypted identification information, and, after receiving another encryption key, switches the encryption key from the encryption key to the other encryption key. A server receives the encrypted identification information from the identification information transmitter, determines whether the encryption key is to be switched, and, if the encryption key is to be switched, generates the other encryption key. Another server authenticates the identification information that an identification information receiver receives from the identification information transmitter, and, if authentication is successful, acquires the other encryption key from the server, and transmits the other encryption key to the identification information receiver.

Abstract: An information distribution system includes a sound wave transmitter, a mobile terminal, and an information distribution device. The sound wave transmitter transmits identification information to identify the sound wave transmitter. The mobile terminal receives the identification information and transmits the identification information to the information distribution device. The information distribution device is configured to transmit distribution information related to the identification information received from the mobile terminal to the mobile terminal. The information distribution device counts a number of the mobile terminal that transmits each identification information every predetermined period and identification information and transmits the distribution information to the mobile terminal that transmits the identification information in which the number of the mobile terminal reaches a predetermined number.

Abstract: An information distribution system includes an information distribution apparatus, a sound wave generator that outputs a sound wave including first identification information, and a terminal that transmits an information distribution request. The information distribution apparatus includes a determining unit and a distribution control unit. When a distance between a location of the sound wave generator identified from the first identification information included in a first information distribution request received at a first time and a location of the sound wave generator identified from the first identification information included in a second information distribution request received at a second time prior to the first time is a threshold or less, the determining unit determines that the second identification information included in the first information distribution request is valid.

Abstract: A disclosed ink cartridge includes a primary ink room and at least one secondary ink room arranged adjacent to the primary ink room, which rooms are configured to store ink therein. An ink supplying needle is made to pierce through the secondary ink room in such a manner that at least a needle hole provided in the ink supplying needle reaches the primary ink room so as to suction the ink from the primary ink room through the needle hole and supply the ink to an inkjet recording head via an ink supplying path. As the ink supplying needle is pulled out from the primary ink room, the needle hole passes through the secondary ink room so that the ink supplying needle can suction the ink from the secondary ink room.

Abstract: The device for mounting a cooking apparatus of the present invention under a horizontal plate such as a bottom plate of wall cabinet comprises an upper flat metallic plate fixedly mounted on the upper surface of the horizontal plate and lower metallic fitting member fixedly mounted on the lower surface of the horizontal plate; sliding metallic member engaged on the lower metallic fitting member in a laterally slidable manner; and a stopper for fixing a relative position between the lower metallic fitting member and the sliding metallic member. The cooking apparatus is supported by hanging the engaging portions formed in the side end portions of the lower metallic fitting member and the sliding metallic member on handles provided on both the left and right side surfaces of the cooking apparatus.

Abstract: The device for mounting a cooking apparatus of the present invention on a wall and the like in a kitchen comprises a wall fixing member to be fixedly mounted on the wall and provided with reinforcing members projecting forward; a supporting member rotatable up-and downwardly and provided with grooves in which the legs of the cooking apparatus are to be put; and a stopper member for preventing the legs of the cooking apparatus from coming off the grooves of the supporting member in case that the cooking apparatus is supported by said supporting member. Accordingly, the cooking apparatus can be easily mounted on the wall and the like in the kitchen without any extra members to be mounted on the cooking apparatus, so that a cooking apparatus of such a type originally used by being placed on a cooking counter and the like can be easily mounted on a wall in a kitchen.
