Abstract: A microbubble cleaning system includes a tank in which a solution into which a product is immersed to clean the product is stored; supplying means for putting microbubbles into the solution and supplying the solution that includes the microbubbles into the tank; oil separating apparatus that collects bubbles that have risen to a surface of the solution stored in the tank as a result of cleaning the product, as well as a portion of the solution that is near the surface of the solution, in order to separate oil from the solution; generating means for generating a surface flow of the solution near the surface of the solution in order to remove the bubbles that have risen to the surface of the solution in the tank; and removing means for removing carbon dioxide from air that is used to generate the microbubbles by the supplying means.

Abstract: An agent managing system which enables a user to readily control, from outside, internal information of an agent performing autonomous coordinating operations. The system comprises a program for requesting monitoring and controlling of the agent from outside, and a program for interchanging the necessary information to/from the agent in accordance with the request from the program. As a result, while the agent can independently carry out the autonomous coordinating process as the conventional system, it also becomes possible to control the internal information of the agent securely and flexibly from outside.

Abstract: The present invention makes it possible for a user to share a virtual three dimensional space consisting of a plurality of media in a large wide-area network which includes a wide-band/high-speed network and narrow-band/low-speed network, without causing congestion in the network. The present invention include a multicast message transmitting unit and multicast message receiving unit for performing multicast communication in the wide-band/high-speed network, a unicast message transmitting unit and unicast message receiving unit for performing unicast communication in the narrow-band/low-speed network. A multicast group managing unit, multicast message generating unit and unicast message generating unit coordinate the unicast communication and the multicast communication.
