    • An object is to provide a technique for improving welding strength between an intermediate member and an electrode member. In a section of a spark plug cut by a plane which passes through the center of gravity of the intermediate member and is in parallel with the facing direction between a center electrode and an extending portion of a ground electrode, the spark plug satisfies the relational expression S1/(D1×H1)≧0.005, where S1 is the total area of nuggets, H1 is the height of the end surface of a noble metal tip from the disposition surface of an electrode base metal, and D1 is the maximum width of the noble metal tip.
    • 本发明的目的是提供一种用于提高中间构件和电极构件之间的焊接强度的技术。 在由穿过中间构件的重心并与接地电极的中心电极和延伸部分之间的相对方向平行的平面切割的火花塞的一部分中,火花塞满足关系式 S1 /(D1×H1)≥0.005,其中S1是块的总面积,H1是贵金属端头从电极母材的配置表面的端面的高度,D1是 贵金属尖端。

    • An optical head 1 of an image recording apparatus 10 is provided with a light-source water-cooling jacket 41 for cooling a light source 11 and a device water-cooling jacket 42 for cooling the Grating Light Valve 12 and a light-shield water-cooling jacket 43. The optical head 10 is also provided with a mirror 31 for reflecting a light form the light source 11 in a non-recording status and mirrors 32, 33 for reflecting non-signal light beams from the light valve 12, and the lights from these mirrors are directed to the light-shield water-cooling jacket 43. Further, a refrigerant from a chiller unit goes through the light-source water-cooling jacket 41, the device water-cooling jacket 42 and the light-shield water-cooling jacket 43 in this order. With this constitution, it is possible to efficiently cool all the heat sources and in the optical head.
    • 图像记录装置10的光头1设置有用于冷却光源11的光源水冷套41和用于冷却光栅灯12的装置水冷套42和遮光水冷却套, 光学头10还设置有用于将光源11的光以非记录状态反射的反射镜31和用于反射来自光阀12的非信号光束的反射镜32,33, 来自这些反射镜的光被引导到遮光罩水冷套管43.此外,来自冷却器单元的制冷剂经过光源水冷套管41,装置水冷套管42和遮光水 冷却夹套43。 利用这种结构,可以有效地冷却所有的热源和光学头。
