摘要： A laser processing method including a first step of irradiating a surface of a workpiece with a laser beam with a focal point spaced from the surface, and forming a bottomed hole on the workpiece, which is defined with a tubular inner circumferential face opening at the surface and a bottom face; and a second step of irradiating the bottom face with a laser beam while an assist gas is blown into an opening of the bottomed hole but not blown onto an area surrounding the opening, and forming a through hole penetrating through the workpiece. A laser processing system includes a processing head focusing a laser beam emitted from a laser oscillator so as to irradiate a workpiece with the laser beam and blowing an assist gas onto the workpiece; and a control section controlling the first and second steps as an operation of the processing head.

摘要： A piercing nozzle (2) having a nozzle hole (2a) larger than the diameter of a converged laser beam (10) and smaller than the diameter of a hole (1a) of a cutting nozzle (1) is in use. Further, an underlay (3) having a hole (3a) at a position corresponding to the nozzle hole (2a) is placed under the piercing nozzle (2) through a clearance (5). Piercing is carried out by irradiating the laser beam (10) to a machining target (6) through nozzle holes (1a, 2a) and (3a) on condition that a laser oscillator is set to output high power. The diameter of a hole machined by the piercing is small, and less scattered dross is produced. The scattered dross is cooled down within the clearance (5) and is then dropped down to the underlay (3), so that the adhesion of the scattered dross to the machining target does not occur. Since a small hole is machined with the high power, the machining time for piercing is remarkably shortened.

摘要翻译：使用具有大于会聚的激光束（10）的直径并且小于切割喷嘴（1）的孔（1a）的直径的喷嘴孔（2a）的穿刺喷嘴（2）。此外，在与喷嘴孔（2a）对应的位置具有孔（3a）的底垫（3）通过间隙（5）放置在穿刺喷嘴（2）的下方。在激光振荡器设定为输出高功率的条件下，通过喷嘴孔（1a，2a）和（3a）将激光束（10）照射到加工对象（6）上来进行穿孔。由穿孔机加工的孔的直径小，产生较少散落的渣滓。分散的渣滓在间隙（5）内被冷却，然后下降到底层（3），使得不会发生散射浮渣对加工对象的粘附。由于通过高功率加工小孔，所以穿孔加工时间显着缩短。

摘要： A foot bath including a bath body for containing hot water, in which a foot is to be inserted, the bath body having a cover having an opening therein. A ceramic layer and a heater are provided in the cover so that the heater heats the ceramic layer to produce far infrared rays to irradiate the foot and hot water in the bath body. A structure is provided beneath the bath body for providing vibration to the foot. A pump is connected to the vibration structure so as to be driven thereby and an air transferring pipe is connected between the pump and the bottom of the bath body to transfer air therethrough while the air is heated by the far infrared radiation. A nozzle is provided in the bath body to mix the heated air and hot water and to eject the mixture of heated air and hot water at the surface of the hot water in a jet water stream.
