Abstract: A foaming nozzle is connected to a gas generating device for generating a high-pressure gas which has a pressure higher than an atmospheric pressure and spouting the high-pressure gas from the tip of the nozzle, and the foaming nozzle foams, while stirring, a liquid located in the direction of the spouting. The foaming nozzle has formed in the tip thereof at least two kinds of spouting holes for spouting the high-pressure gas. At least one kind of spouting hole is formed in a shape different from the shape of the other kind of spouting hole so as to spout the high-pressure gas at a speed different from the speed of the high-pressure gas spouted from the other kind of spouting hole.

Abstract: A foaming nozzle which allows even an unskilled person to easily generate fine sustainable high-quality foam by spouting a high-pressure gas generated by a high-pressure gas generating device to a liquid to be foamed. A foaming nozzle is connected to a gas generating device for generating a high-pressure gas which has a pressure higher than an atmospheric pressure and spouting the high-pressure gas from the tip of the nozzle, and the foaming nozzle foams, while stirring, a liquid located in the direction of the spouting. The foaming nozzle has formed in the tip thereof at least two kinds of spouting holes for spouting the high-pressure gas. At least one kind of spouting hole is formed in a shape different from the shape of the other kind of spouting hole so as to spout the high-pressure gas at a speed different from the speed of the high-pressure gas spouted from the other kind of spouting hole.

Abstract: An inked ribbon cartridge having an inked ribbon to be used for printing by an impact printer includes first and second cores having the ribbon wound thereon, and first and second ratchet cores directly coupled to the first and second ribbon cores. In addition, first and second levers have first ends which are selectively engaged with the first and second ratchet cores while opposite ends of the first and second levers are in contact with the inked ribbon for detecting a tension in the inked ribbon. Accordingly, the ribbon can be fed by providing a low torque to the first and second ribbon cores.
