    摘要： An electrically conductive composite fiber comprising an electrically conductive layer formed of a polyester-based polymer (A) having a melting point of 200° C. or higher and containing from 23 to 33% by weight of electrically conductive carbon black, and a protective layer formed of a polyester-based polymer (B) having a melting point of 210° C. or higher, wherein the difference between the SP value of the (A) and the SP value of the (B) is adjusted to not greater than a predetermined value and the fiber strength and the elongation at break are adjusted within certain ranges. This can make it possible to obtain an electrically conductive composite fiber that has a superior antistatic performance, which is not degraded very much over a practical wearing for a long term, though it contains only a relatively small amount of electrically conductive carbon black, and that is suitable for the field of clothing such as clean room wears and working wears.

    摘要： A control rod for nuclear reactors includes four wings including neutron absorbers containing hafnium, a front end structural member which has a cross shape in cross section and includes brackets bonded to the leading ends of the wings, and a terminal end structural member which has a cross shape in cross section and includes brackets bonded to the tailing ends of the wings. The four wings are bonded to a wing-bonding member including a cross-shaped center shaft so as to form a cross shape. The front end structural member and the wing-bonding member are made of a zirconium alloy. The wings include neutron-absorbing plates having neutron-absorbing portions and each have an outer surface which is opposed to a fuel assembly and at which a hafnium-zircaloy composite member covered with zircaloy is disposed. The neutron-absorbing plates are opposed to each other with trap spaces disposed therebetween.
