  • Patent number: 7346547
    Abstract: A method, device, system, and program for transaction of contents through a network are provided. In this transaction system, user terminals are configured to allow users to conduct transactions. A user sends a notification that the user hopes to register contents and prescribed items thereof in a data base in a center through the Internet. A Web server in the center registers the contents and the prescribed items thereof sent from the user in the data base. When use or transfer of the contents sent from the user occurs, a token according to the occurrence is sent to a user who hopes to use or transfer of the contents. In the case of accidents concerning contents and tokens, appropriation/compensation is implemented from funds for handling trouble to a user who suffers a loss of benefit. Thereby, it becomes possible to conduct transaction of contents easily and securely, spread around detail of contents extensively, and receive contents promptly which a user hopes to use.

  • Patent number: 7306640
    Abstract: A vacuum cleaner includes a first dirt separation unit and a second dirt separation unit. The first dirt separation unit has a first inlet port through which a suction air stream including dirt particles is introduced thereinto, and the second dirt separation unit has a second inlet port through which the air stream introduced into the first dirt separation unit is introduced into the second dirt separation. The first and the second inlet port are disposed such that they are not registered with each other. Accordingly, the dirt particles suctioned are separated in two stages, thereby decreasing the possibility of occlusion of a filter and rapid deterioration of a suction force.
