  • Patent number: 7177384
    Abstract: A basket has a lattice-like section for accommodating individual used nuclear fuel in predetermined positions in a cask. The basket is made from aluminum composite material having good neutron absorption ability, excellent mechanical property and workability. The aluminum composite material is made by having, in an Al or Al alloy base phase, B or B compound with a neutron absorption ability and an additive element, e.g. Zr or Ti, for giving a high strength property, and subjecting to a sintering under pressure.

  • Patent number: 4235722
    Abstract: A liquid treating unit includes a module comprising a channel member for collecting a product liquid for recovery; a semipermeable membrane member liquid-tightly joined to the channel member and made from a semipermeable membrane strip by alternately folding the strip longitudinally thereof to provide feed liquid passages and product liquid passages on the front and rear sides of the membrane respectively, each pair of product liquid passages defining leaf portions of the membrane being adhered at each end of the passage to liquid-tightly close the product liquid passage only; spacers inserted into the feed liquid passages; and a covering member surrounding the outer periphery of the membrane member. The feed liquid passages therefore have a regulated cross sectional area to permit the feed liquid to flow through the passages in parallel and straight direction at an increased speed relative to the membrane surface, ensuring a reduction in dead space and efficient use of the membrane.

  • Patent number: 3979521
    Abstract: Fruit wines excellent in taste and bouquet can be manufactured from fruit juices of low sugar content by subjecting the crude fruit juices to a semi-permeable membrane separation process (reverse osmosis or ultrafiltration), thereby to concentrate the crude fruit juices. The time periods required for fermenting the concentrated fruit juices and aging the wines made therefrom are considerably shorter in comparison with other wine-making processes.
