IPC: B63B21/44
Filed: 1983-04-21
Abstract: PURPOSE:To enable an anchor to bite stably, deeply, and reliably during anchoring, by a method wherein ridge lines of two flukes are respectively bent inwardly to form a recess, the cross section is formed in a rhomb, and a stabilizer has a concave surface extending downward toward the outside from the lower parts on both sides of the fluke. CONSTITUTION:Two flukes 1 and 1' at a head part A are constituted such that ridge lines 2 and 2' are respectively bent inwardly to form a recess, and the longitudinal cross section thereof is formed in a rhomb. Both sides of a body part (a) are protruded from the lower parts on both sides of each of the two flukes 1 and 1' toward the outside to form a stabilizer 3 with cross section which has a concave surface extending downward. This constitution enables increase in the surface areas of the flukes 1 and 1', and inward bonding of its rhombic cross section and the ridge lines 2 and 2' enables rapid and deep biting of an anchor during anchoring. Further, the stabilizer 3 can aid in increasing stability during anchoring.

Title: Method for inserting linear body into tube
Inventor: YABUKI YOICHI
IPC: H01B13/22
Filed: 1988-03-28
Abstract: PURPOSE:To insert a linear body into minimum space without damaging it by imparting flexibility to the linear body, and inserting it into a tube. CONSTITUTION:The linear body is coated with such thing as synthetic resin so as to impart flexibility, and inserted into the tube 5. That is, since the linear body 7 is induced to be straight due to its flexibility, it hardly generates waviness, even if it generates waviness, the coefficient of friction between the linear body 7 and the internal surface of the tube 1 is small. And even when the peak and trough of the waviness push the internal surface of the tube 1, stability which is restoring force, acts to reduce the friction, and thus the linear body 7 is not hindered from being inserted into the tube. It returns to its original position from the internal surface of the tube 1 due to elasticity, and further advances. Therefore, the linear body 7 is free from scratches.
