TWO:"Since the opening of Japan to foreigners, the missionaries have devoted much attention to the country as a field of labor. Compared with the result of missionary labors in India, the cause has prospered, and a great deal of good has been accomplished. The Japanese are not an unthinking people, and their faculties of analysis are very keen. They show more interest in the doctrines of Christianity than do the Chinese and some other Oriental people, and are quite willing to discuss them whenever they are properly presented."

Membrane separation type solvent dehydration system

Great attention is recently being paid to global environmental issues, and it is now conceivable that companies will need to treat used solvents themselves. In consideration of this kind of social issue, we have developed a “membrane separation type solvent dehydration system,” which uses a polyimide membrane with superior dehydration properties developed by Ube Industries, Ltd. in combination with our own distillation and concentration technology that has resulted in solvents being more easily recovered.

THREE:"It became necessary to fire on the mutineers, and for this we raised the tarpaulins over one of the hatches. The smoke poured out in a dense mass and almost smothered us, and we could only see the forms of the men very dimly, like a ship in a fog. We fired, and continued to fire till[Pg 397] several of them had been shot down, and all their efforts to get at us were of no avail. There were about sixty men in the crew, and, as we had over a thousand coolies on board, we had numbers against us fearfully. But they had no fire-arms, while we had a good supply of rifles and pistols, with plenty of ammunition. At the time of the outbreak there were not far from a hundred coolies on deck; but we drove them forward, and kept so large a guard over them that they could not have done anything to help their friends below if they had been disposed to do so."He told you?--Ah! you're only guessing," I said, and saw that I was helping her to guess more correctly.
  • 1Under the distillation system, even in case of azeotropic solvent compositions, this system which remove water vapor by the polyimide membrane will easily dehydrate.
  • 2In comparison with the distillation system, it significantly saves on use of steam.
  • 3Dehydration can be performed through merely supplying evaporated vapor to the membrane module and maintaining the differential pressure between the permeable side and the impermeable side.
  • 4Solvent purity of 99.9% or more can be achieved by carrying out dehydration with a polyimide membrane only.
  • 5The polyimide membrane has superior heat and solvent resistance. Therefore, the vapor permeation system reduces contamination of the membrane and thus extends its life.
THREE:"That's a lie," he pleasantly remarked, and lay back, enjoying my silent wrath. "Send him, General," he added, "he's your man."A MANDARIN JUDGE DELIVERING SENTENCE. A MANDARIN JUDGE DELIVERING SENTENCE.

The aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

  • 1 Recovery of the detergent solvent Recovery of the cleaning solvent such as electronic parts industry, precision instrument industry.
  • 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
THREE:"The first kite I saw in the air in Japan was so much like a large bird[Pg 265] that I mistook it for one, and the delusion was kept up by a smaller one that seemed to be getting away from the other. The large one imitated the movements of a hawk to perfection, and it was some minutes before I could understand that it was nothing but a combination of sticks and paper and cords, instead of a real live bird. It rose and fell, and every few moments it swept down and seemed to be trying to swallow the little one out of sight. I never should have supposed such an imitation possible, and was thoroughly convinced that the Japanese must be very fond of kite-flying if they give it the study necessary to bring it to such a state of perfection. "Then it was ever so funny to see the men bowing to each other; they did it with so much dignity, as if they had all been princes, or something of the sort. They rest their hands on their knees, and then bend the body forward; and sometimes they bend so low that their backs are level[Pg 89] enough to set out a tea-service on and use them for a table. When they want to bid good-bye, they say 'Sayonara,' just as we say 'Good-bye,' and it means exactly the same thing. They are not satisfied with one bow, but keep on several times, until you begin to wonder when they will get through. Everybody says they are the politest people in the world, and I can readily believe it if what I have seen is a fair sample.
