摘要： PURPOSE:To prevent a vibration in the region near the rear edge of a propeller from generating a noise by providing a cavity inside a propeller blade in the region near the rear edge thereof. CONSTITUTION:A propeller blade is provided with a plurality of cavities 3 in the region near the rear edge 1 in the width direction thereof. The cavity is formed by closing the opposite ends of a through hole defined in the thickness direction of the blade with cover members 4. The cavity 3 makes a vibration at the rear edge of the blade discontinuous so as to prevent a noise caused by resonance from being generated.

摘要： PURPOSE:To protect a strain gauge positively from ice pieces, by covering the strain gauge mounted on a screw blade of a ship with a metal plate, which is welded securely on the screw blade. CONSTITUTION:A metal base plate 17 having a through groove 18 is welded firmly on a screw blade 1. Then, a strain gauge 2 and a lead 20 thereof are housed in the through groove 18 and the strain gauge 2 is fixed on the blade face 1. Then, the through groove 18 is fitted with an epoxy resin to waterproof the strain gauge 2 and the lead 20. Then, the metal lid plate 19 is welded firmly over the metal base plate 17. Thus, as the strain gauge 2 is fixed securely on the face of the screw blade 1 with a prolonged weld line combining the metal base plate 17 and the metal lid plate 19, the strain gauge is protected from damage otherwise caused by ice piecesf hitting the screw.

摘要： PURPOSE:To attain the input of the 3-dimensional coordinates with high accuracy in a simple constitution without interrupting the pick-in action of the plane coordinates, by providing a voice input mechanism to a cursor to pick in the plane coordinates and also to have the voice input of the height direction coordinates. CONSTITUTION:A Z-coordinate input mechanism 5 is also provided to a cursor 1 provided with an X/Y-coordinate input mechanism 4, etc. The plane coordinates are picked in by the mechanism 4 and the mechanism 5 has the voice input of the height direction coordinates. The 3-dimensional coordinates are supplied to a computer 3, etc., via the Z-coordinate input data control mechanism 9 of a speech recognizing system and X/Y-coordinate input data control mechanism 8 of an electromagnetic induction system. Thus it is possible to have highly accurate input of the 3-dimensional coordinates in a simple constitution and without interrupting the pick-in action of the plane coordinates.

摘要： PURPOSE:To launch a marine structure without being affected by the loading distribution of rig and the variation of tidal level by a method in which a marine structure on the land is mounted on a float, landed on the bottom, the marine structure is erected on its legs, and then the float is floated and removed. CONSTITUTION:A fixing base 5 is provided through legs 8 and a slab 10 on a barge body 4, a water charging valve and a water discharge pump are provided to the barge body 4 to enable it to settle, and the barge 4 is towed to a quay and landed on the bottom by charging water into it. In this case, the height is regulated by using blocks 6 to make the fixing base 5 coincide with the upper face of the quay A, and also the leg 3 is mounted on the barge 4 and brought down to the bottom B under water. Then, the rig 2 is erected. The barge 4 is floated and pulled out of below the rig 1, and the rig body is brought down and floated to complete the launching. Thus, the launching of the rig can be performed without affected by the variation of tidal level and the loading distribution of the rig.

摘要： PURPOSE:To make it possible to easily extract a boringless stern bearing in a short time, by blocking an opening hole at the front and rear ends of the bearing to define a section, and by feeding hot fluid into the section so that a hardened resin material is easily heated and softened. CONSTITUTION:Blocking plates 7, 7a are attached to an opening hole section at the front and rear ends of a bearing 2 to define one section into which steam or hot air is blown from a feed pipe 9. Then, the thereby produced drain is discharged to the outside through a drain pipe 10. Thus, the bearing 2 which is heated at its inner surface, is gradually heated up so that a resin material 3 stuck to the outer peripheral surface of the bearing 2 is gradually heated and softened. Accordingly, after checking the softening of the resin material 3, eye-bolts are attached to the outer surface of the blocking plate 7, and then a pull-out cable is hooked to the eye-bolts 12 to extract the bearing 2. Since the softened resin material 3 serves as a lubricant, the bearing 2 may be easily extracted.

摘要： PURPOSE:To make it possible to simply align a boringless stern bearing with an original center axis only by the circumferential and axial positioning thereof, by removably a positioning plate fitted on the outer periphery of the stern bearing, to a stern keel beam at the front and rear ends of the bearing. CONSTITUTION:When a bearing 2 is extracted for repairing a ship, attaching bolts 5 are removed to take out positioning plates 4, and then a resin material 3 is heated or broken so that the bearing 2 may be removed. When the bearing 2 is reinstalled in a through-hole in a stern keel beam 1 as in its original condition, the positioning plates 4 are fitted onto knock pins 7 at the front and rear end of the through-hole, and are then secured by the bolts 5. Then, the bearing 2 is pushed into the through-hole while it is supported by the secured positioning plates 4, and is circumferentially and axially positioned with the use of aligning marks. Then a resin material 3 is filled in the gap between the stern keel beam 1 and the outer peripheral surface of the bearing 2 and is then hardened to secure the bearing 2 in the keel beam 1. Therefore, the bearing 2 is precisely returned at its original position as is before the removal thereof due to the above-mentioned positioning by the positioning plate.

摘要： PURPOSE:To obtain a propeller having no lower strength, which is simply manufactured and which effectively prevents the occurrence of cry sound, by bonding a resin onto a part of a certain area on a propeller blade to change the thickness and surface-roughness of the blade. CONSTITUTION:A resin 2 is bonded to the trailing end section of each propeller blade 1 in a range of 0.4R to 0.8R where R is the radius of the propeller blade 1, and then a water-resistant bonding agent 3 is applied over the periphery of the resin 2 in order to eliminate the steped part around the resin 2. The resin 2 is formed therein with grooves 2a in a staggered pattern. In comparison with the stream of water before the application of the resin, the stream of water after the application of the resin shifts its burble point forward and changes the generating condition of Karman vortex trail so that cry sound is prevented. Further, the strength of the propeller blade is not lowered, and as well the manufacturing of the propeller becomes simple.
