  • Patent number: 9027745
    Abstract: This distributing device for absorbent articles is provided with a main conveyor path, a branch conveyor path that branches from the main conveyor path, a main conveyor path that conveys absorbent articles along the main conveyor path, a diverting mechanism that diverts absorbent articles in the main conveyor path from the main conveyor path to the branch conveyor path, and a branch conveyor mechanism that conveys the absorbent articles diverted by the diverting mechanism along the branch conveyor path. The diverting mechanism is provided with a diverting part for diverting the absorbent articles. The diverting part moves without stopping, entering the main conveyor path from a standby position outside the main conveyor path and then, after leaving the main conveyor path, returning to the standby position.

  • Patent number: 8821651
    Abstract: A method for surface treating a heat exchanger, a hydrophilizing treatment agent used in this method, and an aluminum heat exchanger obtained from this method are provided that excel in the initial adherence, hydrophilicity, and odor suppressibility, and can maintain these abilities for an extended time, while having little burden on the environment and the human body. The method for surface treating an aluminum heat exchanger that is brazed includes (1) a pickling treatment step; (2) a chemical conversion treatment step; and (3) a hydrophilization treatment step, in which the acidic cleaning agent contains nitric acid and sulfuric acid and contains ferric salt in a predetermined amount, the hydrophilizing treatment agent contains silica grains coated with a vinyl alcohol polymer and a polyallylamine resin.
