摘要： To provide a lighting device which is enabled to light a lamp of an incandescent bulb or the like in high luminance by a battery to be amounted on a vehicle. A lighting source lighting device 10 includes: an inverter 11 for converting a direct current from a vehicle-mounted battery 15 into an alternating current; and current adding means 13 for adding the direct current from the vehicle-mounted battery 15 and alternating current generated by the inverter 11, to supply a light source 14, such as a head lamp, with the added electric current. In this construction, the light source 14 is driven with the electric current containing the direct current and alternating current superimposed thereon so that the light source luminance microscopically changes with the period of the alternating current. With the naked eye, however, what light is trapped from the light source by the afterimage phenomena is a light at a luminous time so that the light source appears more luminous than at a time when only the direct current is applied.

摘要： A cermet tool is made up of a binder metallic phase forming component of Ni or Ni and Co and a hard phase including a hard phase metallic element component of Ti as its main part and one or more of an additional metallic compound selected from V, Cr, Zr, Nb, Mo, Hf, Ta and W. A surface coating layer is formed on the surface of the cermet. The surface coating layer satisfies at least one of the appearance lightness Vs of 6 or more and the saturation Cs of 4 or more. When wear of a tip of a cermet tool proceeds, that part changes its color to a blackish tone (corresponding, for example, to Vs of from 4 to 1 and Cs of from N to 3). By adjusting the appearance lightness and the saturation of the surface coating layer to the ranges described above, a worn part and a non-worn part are easily distinguished by the naked eyes based on the difference in lightness or hue. As a result, distinction of a spent tool and judgement of the life of the tool can be easily conducted.

摘要： A cermet tool and process for making the same is disclosed. The cermet tool has a surface coating layer which exhibits a function equivalent to or higher than a hard coating layer of a conventional cermet tool. The tool is economical to produce since no additional step such as a gas phase film forming method is necessary for the formation of the surface coating layer. The surface coating layer has essentially the same hard phase composition as the interior main body part, but the weight content of the binder metallic phase metallic element component is smaller than the average weight content of the binder metallic phase metallic element component through out the cermet (or the weight content in the main body part). This surface coating layer is formed on the surface outermost part of the cermet body. Because the surface coating layer has a content of the binder metallic phase smaller than that in the main body part, it has a hardness higher than the main body part. As a result, the wear resistance of the tool is improved. Furthermore, the surface coating layer is formed by modifying the surface of the cermet itself without employing another step such as a gas phase film forming method.
摘要翻译：公开了一种金属陶瓷工具及其制造方法。金属陶瓷工具具有表现出与常规金属陶瓷工具的硬涂层相当或更高的功能的表面涂层。该工具经济地生产，因为不需要诸如气相成膜方法的附加步骤来形成表面涂层。表面涂层具有与内部主体部分基本上相同的硬质相组成，但是粘合剂金属相金属元素组分的重量含量小于通过金属陶瓷的粘合剂金属相金属元素组分的平均重量含量（或主体部分的重量含量）。该表面涂层形成在金属陶瓷体的表面最外部。由于表面被覆层的粘结剂金属相的含量比主体部的含量小，所以其硬度比主体部高。结果，改善了工具的耐磨性。此外，通过改变金属陶瓷本身的表面而不使用诸如气相成膜法的其它步骤来形成表面涂层。
