    • A corner or end position indicating apparatus for an automotive vehicle comprises a light source 6 emitting light, and first and second marker point indicators 2 and 3. The first marker point indicator 2, displayed red, is larger and brighter than the second marker point indicator 3 displayed blue. A first optical path is defined between the first marker point indicator 2 and the light source 6, and a second optical path is defined between the second marker point indicator 3 and the light source 6. The first optical path is longer than the second optical path. A concave mirror 5 alters a direction of the light emitted from the light source 5 upward a rear window glass R of the automotive vehicle. The first marker point indicator 2, the light source 6 and the concave mirror 5 are cooperative to form an image 2a of the first marker point indicator 2 at a position corresponding to a corner or end position of a vehicle body. Meanwhile, the second marker point indicator 3, the light source 6 and the concave mirror 5 are cooperative to form an image 3a of the second marker point indicator 3 at a position far from the corner or end position of the vehicle body.
    • 用于机动车辆的拐角或终点位置指示装置包括发光的光源6和第一和第二标记点指示器2和3.显示为红色的第一标记点指示器2比第二标记点指示器更大和更亮 3显示蓝色。 在第一标记点指示器2和光源6之间限定第一光路,并且在第二标记点指示器3和光源6之间限定第二光路。第一光路比第二光路长 。 凹面镜5将从光源5发射的光的方向向上改变为机动车辆的后窗玻璃R. 第一标记点指示符2,光源6和凹面镜5被协调以在对应于车身的拐角或结束位置的位置处形成第一标记点指示器2的图像2a。 同时,第二标记点指示器3,光源6和凹面镜5协调以在远离车体的角落或终点位置的位置处形成第二标记点指示器3的图像3a。

    • An MAG arc welding method and apparatus is capable of achieving a welding bead in a regular ripple pattern or in a suitable sectional form. The welding power source generates the first welding current I1 and a second welding current I2 larger than the first welding current. The wire melting speed is changed by switching between the first and the second welding currents. The welding method or apparatus according to the invention generates the first arc length more than 2 mm and the second arc length more than the first arc length and switches between both arc length at a switching frequency F of 0.5 to 25 Hz. The ratio of the second to the first welding currents is made to be in 1.03 to 1.20. In addition to a welding method to change the arc length by switching the first and the second welding currents at a constant wire feeding rate, the present welding method makes it possible to carry out the lap welding or butt welding even when there is a large gap. The large gap requires a large amount of molten metal which is prepared by increasing the wire melting speed caused by an increase in the wire feeding rate by 5 to 20%. The resultant reinforcement has a beautiful appearance.
    • MAG电弧焊接方法和装置能够以规则的波纹图案或合适的截面形式实现焊珠。 焊接电源产生比第一焊接电流大的第一焊接电流I1和第二焊接电流I2。 通过在第一焊接电流和第二焊接电流之间切换来改变焊丝熔化速度。 根据本发明的焊接方法或装置产生大于2mm的第一弧长和大于第一弧长的第二弧长,并且在切换频率F为0.5至25Hz的两弧长之间切换。 第二焊接电流与第一焊接电流的比率为1.03〜1.20。 除了通过以恒定的丝线进给速度切换第一焊接电流和第二焊接电流来改变电弧长度的焊接方法之外,本焊接方法即使当存在较大间隙时也可以进行搭接焊接或对接焊接 。 大的间隙需要大量的熔融金属,这是通过增加引线进给速度所引起的焊丝熔化速度提高5至20%来制备的。 所得的加强件具有美观的外观。
