Abstract: A W/O type emulsified fat composition is provided having an oily phase and an aqueous phase, wherein the oily phase contains 40 to less than 95% by weight of diglycerides and 5 to less than 60% by weight of triglycerides and satisfies the following requirements (1) and (2):(1) the diglycerides have 0.5 to less than 20% by weight of SS components, 20 to less than 55% by weight of SU components, and 25 to less than 70% by weight of UU components (wherein S is a C.sub.14-22 saturated fatty acid group and U is a C.sub.14-22 unsaturated fatty acid group), and(2) the weight ratio of the C.sub.14 and C.sub.16 saturated fatty acid groups contained in the diglycerides to the C.sub.18, C.sub.20, and C.sub.22 saturated fatty acid groups contained in the diglycerides is 1.0 to 8.0, and its use as a margarine or the like, having excellent stability and satisfactory spreadability.

Abstract: This specification discloses an invention directed to an ultrasonic cleaning apparatus for cleaning a cleaning target. The ultrasonic cleaning apparatus includes a liquid discharge nozzle having a discharge port to discharge a liquid therethrough, an ultrasonic vibrator for applying ultrasonic vibrations to the liquid which is to be supplied to the nozzle, and a cleaning member which is mounted on the discharge port of the nozzle, vibrates while holding therein the liquid discharged through the discharge port, and comes into contact with the cleaning target with a predetermined area, thereby scrub-cleaning the surface of the cleaning target.

Abstract: A polyol fatty acid ester having mixed acid groups is produced by reacting a partial ester of a polyol and a branched fatty acid with a a straight chain fatty acid or a lower alcohol ester thereof in the presence of a lipase. The obtained glyceride mixture contains a large amount of diglyceride having a branched, saturated fatty acid group and a straight chain, saturated fatty acid group.

Abstract: An oil-in-water emulsion comprises an aqueous phase of water and an oil phase comprising an edible oil composition comprising 10 to 99 percent by weight, based on the entire oils and fats of the emulsion, of a diglyceride mixture containing the diglycerides having an increasing melting point of 20 degree centigrade or less. It may be mixed with a protein, lecithin or phospholipid.

Abstract: The following diacylglycerin is useful for a cosmetic oil and a cosmetic composition such as pack, cream and emulsion. ##STR1## (where one each of R.sub.1, R.sub.2, and R.sub.3 denotes a residue of a straight-chain saturated fatty acid having 11-17 carbon atoms, a residue of a branched-chain saturated fatty acid having 10-18 carbon atoms, and a hydrogen atom).
