    • A door lock device includes a striker secured to a vehicle body and a latch plate installed on a vehicle door. The striker has a base portion fixed on the vehicle body, first and second leg portions extending from the base portion, a bridge portion extending between and interconnecting the first and second leg portions, and a projection portion which extends from the bridge portion and extends on the outboard side of the first leg portion. The latch member has first and second engaging portions defining therebetween a recess portion in which the first leg portion of the striker is receivable. The first engaging portion is arranged to overlap the projection portion and the second engaging portion is arranged to overlap the bridge portion.
    • 门锁装置包括固定到车身的撞针和安装在车门上的闩锁板。 撞针具有固定在车体上的基部,从基部延伸的第一和第二腿部,在第一和第二腿部之间延伸并在其之间互连的桥接部分,以及从桥接部分延伸并延伸到 第一腿部的外侧。 闩锁构件具有限定其间的凹部的第一和第二接合部,其中可接收撞击件的第一腿部。 第一接合部分布置成与突出部分重叠,并且第二接合部分布置成与桥接部分重叠。

    • A method of ameliorating the residual stresses in a metallic duplex tube and the like and an apparatus therefor, wherein the duplex tube includes a main tube defining the outer tube, and a thermal sleeve defining the inner tube which is inserted to the outer tube, the thermal sleeve being welded onto the inside of the main tube at its root. The method comprises the steps of supplying cooling water in the duplex tube; fitting a restraining ring externally onto the outer surface of the main tube at a position corresponding to the thermal sleeve root; and heating the main tube from its outer surface so as to generate a temperature difference across the main tube wall. The apparatus thereof comprises a cooling water feeding means for supplying the cooling water in the double tube; a restraining ring fitted externally onto the outer surface of the main tube at a position corresponding to the thermal sleeve root; and heating means for heating the main tube from its outer surface so as to generate a temperature difference across the main tube wall.
    • 一种改善金属双相管等中的残余应力的方法及其装置,其中双面管包括限定外管的主管和限定插入外管的内管的热套筒, 热套在其根部焊接在主管的内部。 该方法包括以下步骤:在双工管中供应冷却水; 在对应于热套筒根部的位置处将限制环外部装配到主管的外表面上; 并从其外表面加热主管,以便在主管壁上产生温差。 其装置包括用于在双管中供应冷却水的冷却水供给装置; 限制环在与热套筒根对应的位置处外部安装在主管的外表面上; 以及用于从其外表面加热主管以便在主管壁上产生温度差的加热装置。
