  • Patent number: 6973694
    Abstract: An electric toothbrush with a handle and a brush member having a brush head, individual cylindrical bristle holders with tufts of bristles held rotatably in the brush head. They are set into an oscillatory rotating movement by means of a connecting rod executing a reciprocating sliding movement and simultaneously an oscillatory movement about its longitudinal axis, with transverse grooves, disposed therein. In addition, a bristle holder plate in the brush head is held so as to oscillate about a shaft running in the longitudinal direction of the toothbrush. Thus, during the oscillatory movement of the bristle holders the bristle holder plate swivels back and forth in synchronism with the connecting rod.

  • Patent number: 6968592
    Abstract: A self-running vacuum cleaner comprises a homing mode of following a back of a user with receiving a signal from a light emitting means or a transmitting means of a position indicator means held by the user, an instruction operation mode, in which the user instructs a cleaning area to the self-running vacuum cleaner, and an execution mode for cleaning up the cleaning area instructed. When the self-running vacuum cleaner operates under the homing mode or the instruction mode, a signal from the light-emitting means or the transmitting means is received by a receiver means attached on a periphery portion of a measuring means, which is provided in an upper portion of the vacuum cleaner. Comparing the signals from the two (2) receiver means in strength thereof determines the distance and the direction from the position indicated by the light-emitting means or the transmitting means up to the vacuum cleaner.
