摘要： The invention provides a switching electrode which has a small variation in resistance value even when a large amount of current is repeatedly cut off and can carry a stable amount of current even when it is continuously used. In the invention, the switching electrode is used in a switch which includes a first switching electrode tip (21) and a second switching electrode tip (22), brings the first switching electrode tip (21) and the second switching electrode tip (22) into surface contact with each other to carry a current, and separates the first switching electrode tip (21) and the second switching electrode tip (22) to cut off the current. At least one of contact surfaces of the first switching electrode tip (21) and the second switching electrode tip (22) is a flat surface having an uneven portion.
摘要翻译： 本发明提供即使在大量电流被重复切断时也具有小的电阻值变化的开关电极，即使连续使用也能够承载稳定的电流量。 在本发明中，开关电极用于包括第一开关电极端（21）和第二开关电极端（22）的开关中，使第一开关电极端（21）和第二开关电极端（22） 彼此接触以携带电流，并且分离第一开关电极头（21）和第二开关电极端（22）以截止电流。 第一开关电极端部（21）和第二开关电极端部（22）的至少一个接触面是具有凹凸部的平坦面。

摘要： A laser machining apparatus 1 includes: a laser head that is supported by a laser moving device so as to be movable in X, Y, and Z directions above a motor driven conveyor that transports a workpiece loaded thereon. The laser head includes protection glass for protecting a laser focusing lens; an ultraviolet irradiation device disposed beside the conveyor such that a laser light axis and an ultraviolet ray axis are parallel to each other; and a control device that controls the components of the laser machining apparatus so that the ultraviolet irradiation device radiates UV rays on the protection glass in a state in which a UV irradiation port faces a laser irradiation port of the laser head, thus cleaning the protection glass without removing it from the laser head.

摘要： In the method for cleaning optical components by UV ashing according to the present embodiment, while supplying humidity-controlled humidified gas, ultraviolet rays are radiated to the surface of the protective glass to remove organic matters on the surface of the protective glass. Further, in the cleaning method of the present embodiment, the humidified gas is supplied so that the humidity in the laser head during cleaning becomes 30% to 90%.
