A smectic liquid crystal composition containing component (AI), component (B) and/or component (C), expressed by the following formulas: ##STR1## wherein R.sup.1 represents an alkyl group of 1 to 9 carbon atoms, R.sup.2 represents an alkyl group of 1 to 9 carbon atoms, R.sup.3 represents an alkyl group of 1 to 18 carbon atoms, R.sup.4 represents an alkyl group of 1 to 18 carbon atoms, X represents H or F, R.sup.5 represents an alkyl group of 6 to 15 carbon atoms and R.sup.6 represents an alkyl group of 6 to 15 carbon atoms. Ferroelectric liquid crystal material having a negative dielectric anisotropy is applicable to display element utilizing AC-stabilizing effect and .tau.-Vmin. Further, as to the composition containing ##STR2## as an additional component, SA phase appears within a broad range; hence the composition can be made up into a ferroelectric liquid crystal composition having a good alignment.

    摘要： An iron type head body comprises: a material body 13 made from a forgeable metal; and a disparate metallic member 12 made from a metal having nearly equal or smaller specific gravity than the material body 13, and different constituents. By providing the disparate metallic member 12 inside the upper portion of the head body not adjacent to the sole, the head can be lightened. Moreover, by confining the disparate metallic member 12 in the portion upside of the sole 4 not adjacent to the sole 5, the head body 11 can be hypobaric, while the C.G. of the head 2 can be lowered entirely in addition to being lightened.
