摘要： PURPOSE:To obtain a high wave-dissipating effect by forming a wave-dissipating mechanism section with a plurality of wing-shaped shelves and installing an embankment-body stabilizing holding mechanism with a floater to the lower section of the wave-dissipating mechanism section. CONSTITUTION:A wave-dissipating mechanism section 11 with an approximately streamline-shaped wing-shaped shelves 14 having clearances in the vertical direction is formed, and posts 16 consisting of steel, etc., are mounted into through-holes 15 formed to the shelves 14. An embankment-body stabilizing holding mechanism 12 with bearing members 17 set up at the base ends of the posts 16 and floaters 18 composed of a buoyancy material is installed to the lower section of the wave-dissipating mechanism section 11, and fixed onto anchor bodies 20 by anchor connecting members 21. Accordingly, the shelves 14 are arranged near a water surface, and entering waves are changed into a horizontal motion (b) from a circular motion (a) within the spaces of the shelves 14, thus stably holding a floating wave-dissipating embankment 10.

摘要： In a spot welding method for a high strength steel sheet having a carbon content of 0.15% by mass or greater and a tensile strength of 980 MPa or greater, an object is to obtain high, stable delayed fracture resistance characteristics while variation is suppressed in hardness reduction by tempering. The spot welding method is a method of performing spot welding to obtain a spot welded joint, the method including a spot welding with two-stage welding, setting a ratio (I2/I1) of a current I2 of a second welding process to a current I1 of a first welding process to from 0.5 to 0.8, setting a time tc of a cooling process within a range of from 0.8 x tmin to 2.5 x tmin wherein tmin is calculated using the equation (0.2 x H2) according to a sheet thickness H of the steel sheets, setting an welding time t2 of a second welding process within a range of from 0.7 x tmin to 2.5 x tmin, and setting a pressure from the cooling process onward to greater than a pressure until the first welding process.

摘要： A hydroforming apparatus and working method able to simply find a load path are proposed, which system and method use a mold in which contact sensors able to judge contact with a metal tube inside the mold are mounted at least at two different positions in the tube axial direction, perform a first step of axially pushing tube ends in a state with the internal pressure held at a constant value and stopping the progress of the axial pushing action when judging that among the contact sensors not yet in contact mounted at positions closest to the tube ends detect contact with the metal tube, next perform a second step of raising only the internal pressure while leaving the positions of the tube ends fixed and stopping the increase in the internal pressure when the contact sensor not yet in contact judges contact, next perform a third step of lowering the internal pressure to the value before raising it while leaving the positions of the tube ends fixed, and repeat said first step to third step until all of said contact sensors judge contact so as to obtain a hydroformed part.

摘要： Intended are to improve the yield by minimizing the discarding allowance of a tube end, to prevent a clamping wrinkle by loading an internal pressure, to reduce the number of hydroforming and previous tube-end working steps, to reduce the cost for a mold by simplifying the mold mechanism, and to sample hydroformed parts flanged all over the whole length. For these intentions, there is provided a hydroforming method. In this method, the ends of a metal tube are mounted in a state of being swelled out from a lower mold. A seal punch is gradually pushed to the end of the metal tube while injecting a pressure fluid through the inside of the seal punch into the metal tube, thereby to apply a predetermined pushing force. The pressure fluid fills up the inside of the metal tube thereby to apply a predetermined internal pressure. With the internal pressure and the pushing pressure being applied, an upper mold is then lowered to clamp and deform the tube end out of the mold, thereby to finish the working. Alternatively, after the clamping step, the internal pressure in the metal tube rises to finish the working. Further provided is a hydroformed part, which is so worked by that method as to have a flange all over the whole length in the longitudinal direction.
