    Abstract: Rubber compounds comprising a specific type of polyorganosiloxane of the following formula ##STR1## in which R and R' independently represent a hydrocarbon substituent and n is an integer of not smaller than 3 provided that at least 6 mole % of the substituents R and R' consists of a hydrocarbon group having Small's molecular attraction constant not smaller than 350. Carbon black is added to the polyorganosiloxane whereby various physical properties are improved including breaking strength, water and hot water resistances. The rubber compound may further comprise at least one organic rubber other than the above polyorganosiloxane.

    Abstract: Magnesium alloys containing, by mass percent, Al: 10.0 to 13.0%, Si: 0.3 to 1.5%, Mn: 0.1 to 1.0%, and, if desired, Zn: less than 0.8%, the rest being Mg and unavoidable impurities. Neither cracking by the casting is invited nor the mechanical property is spoiled, and the fluidity can be notably improved, and it is possible to make products small in thickness and light in weight.
