  • Publication number: 20100107122
    Abstract: Provided is a system for providing a widget type idle-screen. The system includes a management server, a database, and a user terminal. The database is managed by the management server, and stores and manages widget type idle-screen contents and a dedicated application for driving the widget type idle-screen contents. The user terminal downloads the widget type idle-screen contents from the database and includes the dedicated application for driving the widget type idle-screen contents. The widget type idle-screen contents are activated on the screen of the user terminal in connection with a phone number of a receiver terminal during the standby time of an outgoing call.

  • Patent number: 5185204
    Abstract: Whiskers having a diameter of 0.1-10 .mu.m and a length of 5-200 .mu.m are pelletized and granulated into agglomerates which have a size of 0.1-10 mm and a bulk density of 0.2-1.0 kg/liter.To pelletize, powders of whiskers are moistened with water while mixing to form primary aggregates. Then, the powders and the primary aggregates are subjected to a rolling movement to cause the primary aggregates to grow into secondary aggregates having desired size distribution. Finally, the secondary aggregates are dried to obtain pelletized or granulated agglomerates of whiskers.Handling of whiskers is facilitated because the agglomerates are less bulky and less likely to fly up in the air. When blended into molding materials for fiber reinforcement, however, the agglomerates are readily disintegrated back into separated individual fibers to provide homogeneous dispersion.
