  • Patent number: 8759712
    Abstract: A method of forming stiffened plate by welding a plurality of stiffener materials and a steel plate, so that closed cross-sectional structures are secured onto a surface of the steel plate. The stiffener materials are joined to the steel plate as a result of edge portions of the stiffener materials which are in contact with the steel plate by being laser welded at a predetermined welding speed as a result of a laser having a predetermined output being irradiated from a predetermined direction thereon from the external side of the closed cross-sectional structures. Accordingly, it is possible to achieve an improvement in the weld quality when welding stiffener materials onto a steel plate, and to achieve an improvement in fatigue strength.

  • Publication number: 20100170050
    Abstract: A welded joint improved in fatigue strength, a steel deck using the welded joint, and a process of producing the steel deck are provided. A steel deck 3 includes a steel plate 10 having a paving surface 11 on which a pavement is placed, and stiffeners 20 welded to a lower surface 12 of the steel plate opposite the paving surface. Single bevel grooves 22 are formed at respective edges 21 of each stiffener brought into contact with the steel plate, and a weld metal 30 is deposited in each single bevel groove 22. The weld metal is a low transformation-temperature welding material whose martensitic transformation occurs in a predetermined low temperature range. The groove angle ? of the single bevel grooves 22 and welding conditions are set based on data acquired so as to obtain a fixed dilution ratio of the weld metal 30 through control of penetration rate.

  • Patent number: 5324434
    Abstract: A filter of a water purifying apparatus main body which is housed in a sink is made as a positive electrode, and a DC voltage is applied, by a dry battery cell, between the filter and a negative electrode in a purified water passage. Thus, microbes are prevented from proliferating in tap water which remains in the water purifying apparatus main body. A discharge pipe of the water faucet used exclusively for purified water is made as a negative electrode, and a DC voltage is applied, by the dry battery cell, between the positive electrode in the outlet of a cartridge and the discharge pipe. Thus, microbes are prevented from proliferating in tap water which remains in the water faucet used exclusively for purified water.
