    • Disclosed is a method of forming a reflection film and a heat absorbing film on the inner surface of a panel of a cathode ray tube by using a vacuum vapor-deposition process. In the case of using aluminum as the material for the reflection film, chromium is used as the material for the heat absorbing film. Chromium has a boiling point under a vacuum pressure at the time of vapor-deposition, which is higher than that of aluminum. The mixture of aluminum and chromium is supplied to a heater portion, and is heated and vaporized by the heater portion to be deposited on the inner surface of the panel. In this deposition, aluminum is first vapor-deposited and then chromium is vapor-deposited. Accordingly, the two kinds of films are formed in one vapor-deposition step.
    • 公开了通过使用真空气相沉积工艺在阴极射线管的面板的内表面上形成反射膜和吸热膜的方法。 在使用铝作为反射膜的材料的情况下,使用铬作为吸热膜的材料。 铬在蒸镀时具有真空压力下的沸点,高于铝的沸点。 铝和铬的混合物被供应到加热器部分,并且被加热器部分加热和蒸发以沉积在面板的内表面上。 在该沉积中,首先蒸镀铝,然后蒸镀铬。 因此,在一个气相沉积步骤中形成两种膜。
