  • Lightning protection fastener and cap for lightning protection fastener
    Patent number: 9163656
    Abstract: To provide a lightning protection fastener or the like, that can reliably seal an arc between the cap and a member such as a wing panel. An end part 30A of a cap 30 on an opening side, the end part 30 A facing a member 22 (or member 21), includes a plane 30d orthogonal to an axis line of the cap 30A and a tapered face 30c formed on an outer circumferential side of the plane 30d. A sealant 34 that spills out of the cap 30A upon mounting the cap 30A is present between the tapered face 30c and a surface 22f of the member 22 (sealant 34S).

  • Lightning protection fastener and mounting method thereof
    Patent number: 8717736
    Abstract: A sealant 34 filled into a cap 30A is caused to overflow through both an opening in a first end portion 30a of the cap 30A and a through-hole 40 of the cap 30A when the cap 30A is pressed against a fastener member 25. With regard to the cap 30A, a ratio between inside diameter D1 of the opening on the side of the first end portion 30a and hole diameter D2 of the through-hole 40 in the second end portion 30b is set as follows: 0.10?D2/D1?0.27.

  • Method for continuous drawing of wire rod
    Patent number: 4688411
    Abstract: A wire rod is payed out from a pay-off stand and descaled in a descaling process. After preheating to a predetermined temperature by a preheating device, it is subjected to a lubrication pretreatment through a zinc calcium phosphate solution applied with ultrasonic wave in the lubrication pretreatment process. After rinsing process, the lubrication-pretreated wire rod is coated with a calcium stearate or a sodium stearate in lubricating process. Thereafter, the wire rod is dried sufficiently in drying process, and then added with a predies lubricant in wire drawing process and coiled by a coiler.
