  • Publication number: 20240389975
    Abstract: A positioning arm apparatus for an ultrasound head is provided. The positioning arm apparatus for an ultrasound head according to an embodiment may constantly move the ultrasound head without change in height of the ultrasound head according to a moving distance by simultaneous rotation at two positions and tilting motion at one position. Also, the positioning arm apparatus may be miniaturized and lightweight since it is operated with a mechanical mechanism, and may provide strong fixing strong and easy maneuverability.

  • Publication number: 20240341797
    Abstract: An ultrasonic transmission circulation system of an ultrasound treatment head and method therefor are provided. In the system and the method therefor according to an embodiment, the supply, discharge, and circulation of the ultrasonic transmission medium with respect to the ultrasound treatment head are all possible by means of a single pump. Further, in the system and the method therefor according to an embodiment, a single system is driven by changing a passage through selective opening and closing of the valves in the system according to the material of a membrane, so that there is no need to drive a separate system for each membrane material.

  • Publication number: 20180207869
    Abstract: The present invention provides an apparatus for driving a filament spool of a 3D printer, which rotates the filament spool for wounding a wire-shaped filament in a forward or reverse direction, including a driving motor installed between an extruder for discharging the filament wound on the filament spool toward a hot end nozzle side and the filament spool and configured to generate a driving force in the forward or reverse direction; a feed roller configured to receive the driving force of the driving motor and to transfer the filament wound on the filament spool to an extruder side or to wound back the filament of the extruder on the filament spool; a filament spool driving roller installed between the feed roller and the filament spool and configured to receive the driving force of the driving motor and to rotate the filament spool; and a torque limiter installed between the driving motor and the feed roller and configured to cause a gear on a filament spool side to idle and only a gear on a driving motor

  • Patent number: 9862178
    Abstract: Provided is an apparatus for feeding/discharging a filament for a 3D printer, including a filament supply part which winds the wire-shaped filament and supplies the wound filament; a filament output part which outputs a three-dimensional printed matter by melting and discharging the filament supplied from the filament supply part; and a driving part which supplies the filament from the filament supply part to the filament output part, and discharges the filament from the filament output part toward the filament supply part, wherein the driving part includes a driving motor which is provided at the filament output part to generate a driving force and thus to adapt the filament to be conveyed in a normal direction or a reverse direction; a driving roller which is provided at the filament output part to receive the driving force of the driving motor and to convey the filament in the normal direction or the reverse direction; a conveying roller which is provided at the filament supply part to receive the driving
