Abstract: A power brush assembly for vacuum cleaners is disclosed. In the power brush assembly, a casing is set in the suction part of a vacuum cleaner and defines a suction nozzle used for sucking dust-laden air under pressure into the suction part of the vacuum cleaner. A power brush is set within the casing such that the brush is rotatable and reciprocable to the left and right. This power brush is used for brushing dust and impurities on a target surface. A drive motor generates a rotating force for allowing the power brush to rotate and reciprocate to the left and right within the casing. A power transmission mechanism connects the drive motor to the power brush so as to transmit the rotating force of the drive motor to the power brush.

Abstract: A washing machine, with an inner tub designed to be linearly reciprocable along its vertical axis in addition to being rotatable on the vertical axis during the washing or rinsing process, is disclosed. In the washing machine, a washing tub is suspended within a cabinet forming the profile of the washing machine and having an openable cover at its top end. The washing tub consists of an outer tub suspended within the cabinet and containing water therein, and a perforated inner tub set within the outer tub. This inner tub contains laundries therein, and washes or rinses the laundries during the washing or rinsing process. A drive unit is mounted to the bottom of the outer tub, and rotates and vertically reciprocates the inner tub within a predetermined stroke. The washing machine of this invention thus forms vertical moving currents of water in addition to active swirling currents of water within the inner tub, and prevents laundries from being twisted during the washing or rinsing process.

Abstract: An advertising system uses a broadcast station to transmit a data advertising broadcast including E-coupon information. The broadcasted E-coupon is used as a medium, and an advertiser, TV viewers and shops are connected in a network by a payment company so that active participation in the advertisement by the TV viewers can be promoted. Statistical data relating to the advertised E-coupon is provided to the advertiser so that the effect of advertisement can be determined and improved. According to the invention using the above-described E-coupon data broadcast, the advertiser, the shop and the viewers are linked in a network centering around a payment company server. Viewer participation in the advertising broadcast is promoted, and the advertiser is able to objectively calculate or determine the audience rating and advertising effect. In addition, some of advertising revenue is distributed to the participants in the network so that the effect of the advertising can be maximized.
