TWO:Japanese children are well supplied with dolls and other playthings, and there are certain festivals in which the whole family devotes itself to the preparation or purchase of dolls to amuse the little ones. The greatest of these festivals is known as the "Hina Matsuri," or Feast of Dolls, hina meaning doll, and matsuri being applicable to any kind of feast. It occurs on the third day of the third month, and for several days before the appointed time the shops are filled with dolls just as they are filled among us at Christmas. In fact, the whole business in this line is transacted at this period, and at other times it is next to impossible to procure the things that are so abundant at the Matsuri. Every family that can afford the outlay buys a quantity of images made of wood or enamelled clay, and dressed to represent various imperial, noble, or mythological characters, either of the present time or of some former period in Japanese history. In this way the children are taught a good deal of history, and their delight at the receipt of their presents is quite equal to that of children in Christian lands. Not only dolls, but a great variety of other things, are given to the girls; for the Hina Matsuri is more particularly a festival for girls rather than for boys. The presents are arranged on tables, and there is general rejoicing in the household. Miniature tea and toilet sets, miniature bureaus and wardrobes, and miniature houses are among the things that fall to the lot of a Japanese girl at the time of the Hina Matsuri.

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:And yet this wildly incredible being, this unspeakable travesty of all living organisms, this thing most opposite to humanity, actually breathed and conversed. He was a sentient being. He was more than man, for he could[Pg 169] be turned into something else by simply pressing a stop. Properly understood, there was no doubt that the mechanism permitted the owner of it to run up and down the evolutionary scale of species according to adjustment.

• 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:

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

THREE:

• 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:"Did she give no reason?"

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
