    • A laser hardening device for forming a hardened layer on the surface of an object irradiated by a laser beam is so arranged as to emit a laser beam which is linearly polarized in the incidence plane containing the normal to the surface and the optic axis of the laser beam irradiating the surface. The device comprises a first concave mirror for condensing the laser beam the incidence plane, and a second concave mirror for condensing the laser beam in a perpendicular plane to the incidence plane, the first concave mirror being disposed closer than the second concave mirror to the laser oscillator in the path of the laser beam. Laser beam is therefore absorbed at a high absorption rate by the object, and a hardened layer is formed without coating a laser absorption agent onto the object. The incidence angle of the laser is preferably no less than 60 degrees, and by arranging that the laser beam is parallel on the irradiated surface, a uniform, hardened layer is obtained. Moreover, by blowing shield gas on the irradiated surface from a gas nozzle provided with a smoothing mechanism such as metal mesh, oxidation of the hardened layer or surface melting due to oxidation is prevented and a more desirable hardened surface is obtained.
    • 用于在被激光束照射的物体的表面上形成硬化层的激光淬火装置被布置成发射在包含激光的表面和光轴的法线的入射平面中线性偏振的激光束 光束照射表面。 该装置包括用于将激光束聚焦入射平面的第一凹面镜和用于将激光束在与入射平面垂直的平面中聚光的第二凹面镜,第一凹面镜被设置成比第二凹面镜更靠近激光 振荡器在激光束的路径中。 因此,激光束以物体的高吸收率被吸收,并且形成硬化层而不在激光吸收剂上涂覆物体。 激光的入射角优选为60度以上,通过将激光束平行配置在照射面上,得到均匀的硬化层。 此外,通过从设置有金属网的平滑机构的气体喷嘴在被照射的表面上吹扫保护气体,防止了由于氧化而导致的硬化层的氧化或表面熔融,并且获得了更理想的硬化面。

    • In a built-in-coil substrate, when viewed in perspective in a stacking direction in which insulating layers of a substrate body are stacked, mutually superposed second coil elements are located further inward than inner peripheries of mutually superposed first coil elements. A cavity is continuous between at least one of the second coil elements and one insulating layer that is in contact with the second coil element(s), and another insulating layer that opposes the second coil element(s) such that the second coil element(s) are exposed, and, when viewed in perspective in the stacking direction, the cavities have annular shapes and extend further inward than the outer peripheries of the mutually superposed first coil elements, there being an interval provided between the cavities and these outer peripheries, and further outward than the inner peripheries of the mutually superposed second coil elements.
