  • Patent number: 8276815
    Abstract: A high-speed automatic fire net-based fire instruction control system for a short-range anti-aircraft gun is provided. More particular, the present invention relates to a system, in which when a short-range anti-aircraft gun gunner calibrates values indicated on equipment and follows instructions without personally viewing a flying object that has infiltrated at low altitude, a tracking and automatic fire net is constructed, and the gunner follows fire instructions, thus allowing gunners to easily cope with targets anywhere regardless of the location, such as an anti-aircraft defensive position or a contact area, as long as the targets appear on a detection radar even in unfavorable weather or at night which forbids the targets from being detected and identified with eyes.

  • Patent number: 7291189
    Abstract: A dust collecting apparatus for use in a vacuum cleaner provides improved suction cleaning efficiency. The dust collecting apparatus includes a main body comprising a suction port through which a dust-laden air is drawn, and a first and a second discharge ports through which filtered air is discharged. A filter unit disposed between the suction port and the first discharge port, filters out dusts from the air. A parallel cyclone unit, disposed between the suction port and the second discharge port, removes dusts from the air by centrifugal force. The first discharge port is larger in sectional area than the second discharge port, and therefore, the filter unit has higher dust removal rate than the cyclone unit in the initial stage of the operation. Accordingly, the dust collecting apparatus can provide greater initial suction cleaning efficiency than a dust collecting apparatus having only the cyclone unit.

  • Publication number: 20060000054
    Abstract: A vacuum cleaner suction port assembly has an upper and a lower housings, a first and a second suction ports formed on the lower housing, at least one upper opening pierced in the upper housing, allowing an external air to be drawn therethrough by the suction force of the first and the second suction ports, and at least one lower opening formed on the lower housing, the lower opening located between the first and the second suction ports and fluidly communicating with the upper opening such that the air drawn through the upper opening is guided to between the first and the second suction ports to scatter the dusts therefrom. Accordingly, cleaning efficiency increases not only at both sides, but also at the center of the suction port assembly.
