  • Patent number: 10961608
    Abstract: A magnesium alloy contains, in atomic percent: 5.7 at. % or more and 8.6 at. % or less of Al; 0.6 at. % or more and 1.7 at. % or less of Ca; 0.05 at. % or more and 0.27 at. % or less of Mn; and 0.02 at. % or more and 0.36 at. % or less of a rare earth element (RE); and any one of 0.1 at. % or more and 0.3 at. % or less of Zn and 0.02 at. % or more and 0.18 at. % or less of Sn, wherein the contents in atomic percent satisfy the condition of the inequality of the following Formula (1), and the balance is Mg and inevitable impurities. (Ca+RE)/Al>0.

  • Patent number: 4720605
    Abstract: A closure with improved sealing end surface plates for enclosing connecting portions of a plurality of sizes of a communication cable. The closure includes a sleeve-like closure body divided longitudinally into portions. The two portions are fastened and sealed. Grooves are formed on an inner surface of the closure body at opposite ends thereof to accommodate the sealing end surface plates interposed between the cable and the closure body. Each of the sealing end surface plates includes an annular rubber end plate and a pair of plastic side plates.
