Abstract: A curable composition which comprises at least one of the following (A), (B), and (C) and further contains the following (D) (provided that when (C) is not contained, both (A) and (B) are contained). (A): A silicon-containing polymer in which the content of components having a weight-average molecular weight of 1,000 or lower is 20 wt. % or lower and which has a reactive group A? and one or more Si—O—Si bonds. (B): A silicon-containing polymer in which the content of components having a weight-average molecular weight of 1,000 or lower is 20 wt. % or lower and which has an Si—H group and one or more Si—O—Si bonds. (C): A silicon-containing polymer in which the content of components having a weight-average molecular weight of 1,000 or lower is 20 wt. % or lower and which has a reactive group A?, an Si—H group, and one or more Si—O—Si bonds. (D): A catalyst for curing reaction which is a platinum catalyst.

Abstract: A ?-glucan-containing fat and oil composition contains ?-glucan of microorganism origin or basidiomycete origin. The ?-glucan-containing fat and oil composition has ?-glucan uniformly dispersed in a food without worsening the texture, taste etc. of the food. The novel microorganism can efficiently produce ?-glucan which has a high activity and favorable qualities as ?-glucan of microorganism origin as described above from less expensive saccharides such as sucrose at a high production speed.

Abstract: The present invention provides organic electroluminescent elements selected from polyacene derivatives represented by general formula (I) below: [wherein, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, A1 and A2, which are the same or different, each represents hydrogen atom, a hydrocarbon group, etc., and n denotes an integer of not less than 1]. The organic electroluminescent elements of the present invention can provide materials for organic electroluminescent elements and organic electroluminescent elements, which are excellent in stability, durability, luminance and luminance efficiency.

Abstract: A &bgr;-glucan-containing fat and oil composition characterized by containing &bgr;-glucans extracted from a gramineous plant; and foods, fat and oil emulsified compositions, bakery products, confectionery products, foods or drugs having a prophylactic effect for a habitual disease, processed rice, wheat, corn or soybean products, liquid foods, and processed foods mainly comprising starch which contain the &bgr;-glucan-containing fat and oil composition.

Abstract: Disclosed is a novel sulfidoxymolybdenum dialkylphosphorodithioate represented by the following general formula (I): ##STR1## wherein R stands for a secondary alkyl group having 4 to 30 carbon atoms and four R's may be the same or different, and X stands for O or S and four X's may be the same or different.This compound is very valuable as the lubricant additive.
