IPC: B63B3/42
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce the vibration from a propeller from being transmitted to a hull through a bracket by protruding the bracket from a ship's bottom obliquely backward, setting the angle formed by the rear edge of the bracket and the vertical line raised on a propeller shaft to a specified value or more, rounding the front edge part, and tapering the rear edge part into a wedge form. SOLUTION: A bracket 18 is protruded largely from a ship's bottom 4 obliquely backward, and the angle α 2 formed by the rear edge 18b of the bracket 18 and the vertical line raised on a propeller shaft 12 is set to 45 deg. or more.

Filed: 1991-05-27
Abstract: PURPOSE:To maintain degreasing performance of a degreasing liquid for a long time by providing an Al ion adsorber in a circulating line of a degreasing tank. CONSTITUTION:Al ion is dissolved in the degreasing liquid 2 for dipping treatment of Al alloy. Active carbon in the adsorber 4 of a 1st circulating line 3 adsorbs and separates Al ion from a part of the degreasing liquid 2 in the degreasing tank 1. As the result, conc. of Al ion is suppressed lower and degreasing performance of the degreasing liquid 2 is maintained for a long time to avoid discard of a part of the degreasing liquid 2 and replenishment of the fresh liquid 2 as little as possible. Since oil is removed from the degreasing liquid 2 in a 2nd circulating line 10, service life of active carbon in the adsorber 4 is prolonged.
