    • PROBLEM TO BE SOLVED: To provide a surface treatment method for a sliding member where, when a diamond like carbon film comprising silicon is formed on the surface of a base material, not only sliding properties such as wear resistance but also corrosion resistance can be suitably secured, to provide a sliding member, to provide a mechanical key, and to provide a portable tool.
      SOLUTION: On the surface of a sliding member 10, a nitriding layer 12a for securing the adhesion of a DLC-Si film 13 stacked in the following stage is formed, and thereafter, the DLC-Si film 13 is formed on the surface of the nitriding layer 12a by plasma CVD. Then, treatment temperature at this time is controlled to 350 to 430°C. In this way, the formation of a complex compound of chromium, nitrogen and carbon as a compound to form into an obstacle upon the securance of its corrosion resistance can be suppressed. It is generally known that the formation of the complex compound remarkably reduces its corrosion resistance. Thus, not only sliding properties such as low friction properties and wear resistance but also corrosion resistance can be suitably secured.

    • 要解决的问题：为了提供一种滑动部件的表面处理方法，其中当在基材的表面上形成包含硅的类金刚石碳膜时，不仅具有耐磨性等滑动性能，而且耐腐蚀性 可以适当地固定，以提供滑动构件，以提供机械钥匙，并提供便携式工具。 解决方案：在滑动构件10的表面上，形成用于确保后续层叠的DLC-Si膜13的粘附的氮化层12a，然后在DLC-Si膜13上形成DLC-Si膜13 通过等离子体CVD形成氮化层12a的表面。 此时，此时的处理温度控制在350〜430℃。 以这种方式，可以抑制在其耐腐蚀性的保证下形成作为化合物的铬，氮和碳的复合化合物成障碍物。 通常已知复合化合物的形成显着地降低了其耐腐蚀性。 因此，不仅可以适当地确保滑动性能如低摩擦性能和耐磨性，而且耐腐蚀性。 版权所有（C）2008，JPO＆INPIT

    • PROBLEM TO BE SOLVED: To prevent an image reflected by a mirror main body from becoming a double image as much as possible. SOLUTION: A mirror main body 2 is constituted by forming a Cr film 6 on a rear surface of a glass substrate 5 and a titanium oxide film 7 on a surface thereof. This titanium oxide film 7 functions as an optical catalyst to give the hydrophilic property due to the decomposition of an organic substance (dirt) adhering onto the surface thereof by the action of the optical catalyst. Consequently, even if a water droplet adheres onto the surface of the mirror main body 2, the water droplet is spread on the whole surface of the mirror main body 2 to ensure the confirmation of the rear by the mirror main body 2. Here, since a film thickness of the titanium oxide film 7 is set such that a reflected light optically interferes with a wavelength of 555 nm of which relative luminosity factor of photopic vision is 1, though its reflectance is large, the light reflected by the titanium oxide film 7 and the light reflected by the surface of the glass substrate 5 interfere mutually to eliminate an image reflected by the titanium oxide film 7.
