    • The method of lap-welding of metal plates using a laser beam, wherein at least one of the metal plates is surface-treated, includes putting a metal plate on the other metal plate and forming a gap between the metal plates so that gas generated at the treated surface at the time weld can be dissipated therethrough. A surface-treated first work and a surface-treated second work are placed one on the other and clamped by a clamp with an opening of the clamp centered at the location on the first work to be welded. Then a laser beam is directed to the location to form a weld. The beam is then directed near the inner periphery of the opening to form a heated portion so that the heated portion deflects to form a gap through which the gas generated at the treated surface dissipates thereby reducing gas pressure.
    • 使用激光束对金属板进行搭接焊接的方法,其中至少一个金属板进行表面处理,包括将金属板放置在另一金属板上并在金属板之间形成间隙,使得在 在时间焊接处理的表面可以从其中消散。 经表面处理的第一工件和经表面处理的第二工件一个放置在另一个上并由夹具夹紧,夹具的开口以第一待焊接工件的位置为中心。 然后将激光束导向该位置以形成焊缝。 然后将梁引导到开口的内周边附近以形成加热部分,使得加热部分偏转以形成间隙,在处理的表面处产生的气体通过该间隙消散,由此降低气体压力。

    • A surface acoustic wave device includes a first filter and a second filter, each of them being a surface acoustic wave (SAW) filter including an odd number of at least three InterDigital Transducers (IDTs); an unbalanced terminal to which an unbalanced signal is input; a first balanced terminal from which a signal having a same phase as the unbalanced signal is output; and a second balanced terminal from which a signal having an opposite phase to the unbalanced signal is output. One of electrodes of a first center IDT and one of electrodes of a second center IDT are commonly connected to the unbalanced terminal, the first center IDT and the second center IDT being one out of the odd number of IDTs and locating at a center in the first filter and the second filter respectively. The number of electrode fingers of the first center IDT is an odd number, and the number of electrode fingers of the second center IDT is an even number.

    • A multi-link engine has a piston that moves inside a cylinder. A piston pin connects the piston to an upper link, which is connected to a lower link. A crank pin of a crankshaft supports the lower link thereon. The lower link is pivotally connected to one end of a control link, which is connected at another end to the engine block body by a control shaft. The control shaft is lower than a crank journal of the crankshaft, and disposed on a first side of a plane that is parallel to a cylinder center axis and that contains a center rotational axis of the crank journal. The cylinder center axis is located on a second (i.e., opposite the first side) plane. The control link has a center axis that is parallel to the cylinder center axis when the piston is near top and bottom dead centers.
    • 多连杆发动机具有在气缸内移动的活塞。 活塞销将活塞连接到连接到下部连杆的上部连杆。 曲轴的曲柄销支撑其上的下连杆。 下连杆枢转地连接到控制连杆的一端,控制链的另一端通过控制轴连接到发动机机体主体。 控制轴低于曲轴的曲柄轴颈,并且设置在平行于气缸中心轴线并且包含曲柄轴颈的中心旋转轴线的平面的第一侧上。 气缸中心轴位于第二侧(即,与第一侧相对)的平面上。 当活塞靠近上下死点时,控制连杆具有平行于气缸中心轴线的中心轴线。
