Abstract: The present invention provides a process for producing DHA (docosahexaenoic acid)-containing tofu or soybean milk drink, or a dry powder thereof which does not influence taste even if a DHA-containing fish oil is incorporated at a high concentration, which is stable and of which starting materials are inexpensive. A DHA-containing fish oil emulsion is prepared by mixing soybean milk with a DHA-containing fish oil at a weight ratio of 1:0.2 to 1, and stirring the mixture. Then, soybean milk drink can be produced by further diluting this emulsion with soybean milk to give a predetermined DHA concentration. Still further, DHA-containing tofu can be produced by coagulating the soybean milk containing this emulsion with the addition of a coagulant. Since the same soybean milk as the starting material of tofu or soybean milk drink is used as an emulsifying agent, such a product is obtained that even if DHA is contained at a high concentration, this does not influence a taste or properties of the product.

Abstract: One of the objects of the present invention is to offer novolak type phenolic resins which use phenols and aldehydes as raw materials and give narrow molecular weight distributions.The novolak type phenolic resins of the present invention are those obtained by condensation reaction of phenols with aldehydes in the presence of an oxycarboxylic acid having carboxyl groups, --COOH, and alcoholic hydroxyl groups, --OH, in one molecule. Thus, obtained novolak type phenolic resins show narrow molecular weight distributions, lower viscosity in molten state and, as a consequence, uniformity in curing time.

Abstract: A solid matrix composition which is solid at ambient temperature, which comprises a viscogenic agent, such as an acrylic acid polymer, capable of developing viscosity on contact with water, as dispersed at least in the neighborhood of the surface layer of a matrix particle containing a polyglycerol fatty acid ester or a lipid and an active ingredient. The matrix may be such that a matrix particle containing a polyglycerol fatty acid ester or a lipid and an active ingredient has been coated with a coating composition containing at least one viscogenic agent. Such composition can adhere to the digestive tract and remain there for a prolonged period of time, thereby increasing the bioavailability of the active ingredient. Solid preparations, such as fine granules and granules, contain the above matrix composition.

Abstract: An unscrewing device for threaded plastic plugs applied to bottles has a handle formed by a suitably shaped longitudinal element (11). A cylindrical ring (12) departs from the end of the handle, and is interrupted over a suitable length (T) by a free end in proximity to the end of the element (11) from which it extends. A curved element (13) extends outward from the free end and is directed in an opposite direction, practically forming a trigger. Inside the cylindrical ring (12) can be inserted in succession reduced rings (22, 32) that are also interrupted over suitable lengths (T1-T2) and that present diameters that progressively decrease. The plug to be unscrewed is inserted in the internal holes of the rings (12, 22, 32). The user grips the longitudinal element (11) and pulls on the trigger (13) with the index finger, producing scarfing so that rotating the longitudinal element (11) around the axis of the plug unscrews the plug.

Abstract: The alkaline storage battery comprises a positive electrode, a negative electrode, a separator, and alkaline electrolyte. The separator is a single layer of synthetic fiber non-woven fabric. Treating the separator to increase either the amount of fiber interconnection at the surface or the amount the fibers are broken apart at the surface or both improves separator strength without sacrificing permeability. This prevents internal short circuits, reduces internal pressure, and significantly improves battery lifetime.

Abstract: A scroll type fluid machine has a pair of mutually engaged scrolls, one being made of an aluminum material, and the other being made hard. A wear amount of an engaging tip seal and end plate is reduced, and the growth of wear of both elements is equalized. Tip seals (47, 48) are provided at the tips of wraps (12, 16) of the pair of scrolls (10, 14) and are made of a composite plastic material composed of a polyphenylene sulfide as a base material and a carbon fiber, and other materials as filler. The carbon fiber composition rate of the tip seal material of the scroll (10) made of an aluminum material is made higher than the carbon fiber composition rate of the tip seal material of the other scroll (14) made of an aluminum material having a surface treatment or of a ferrous metal or of a ferrous metal having a surface treatment. Thereby the wear amount of each engaging tip seal (47, 48) and end plate (11, 15) is reduced, and simultaneously the growth of wear of both elements is equalized.
