    • A cation electrodeposition coating process and cation electrodeposition coating composition that have a sufficient throwing power are provided. A process for cationic electrodeposition coating which comprises the steps of:(1) immersing a substrate in a cationic electrodeposition coating composition;(2) applying a voltage between an anode and the substrate, which serves as a cathode, to thereby cause coat film deposition; and(3) further applying a voltage to the coat film deposited so as to increase electric resistance per unit volume of the coat film,wherein, in step (3), coat films are deposited at those sites of the substrate where coat films have not yet been deposited, the cationic electrodeposition coating composition having a time point when the electric resistance per unit volume of the coat film deposited increases in the course of electrodeposition under constant-current conditions.
    • 提供具有足够投掷力的阳离子电沉积涂覆方法和阳离子电沉积涂料组合物。 一种用于阳离子电沉积涂层的方法,其包括以下步骤:(1)将基底浸渍在阳离子电沉积涂料组合物中; (2)在阳极和作为阴极的基板之间施加电压,从而引起涂膜沉积; (3)进一步向沉积的涂膜施加电压,以提高涂膜的每单位体积的电阻,其中,在步骤(3)中,涂布膜沉积在基底上没有涂膜的部位 阳离子电沉积涂料组合物具有当在恒定电流条件下电沉积过程中沉积的涂膜的每单位体积的电阻增加的时间点。

    • A difference processing circuit receives input of welding images taken by a CCD camera in real time and then differentiates power monitoring images recorded in a memory from welding images to obtain difference processing reflected light images. Due to the difference processing performed by a difference processing circuit, foreign matter images included in welding images and power monitoring images are eliminated and the difference processing reflected light images that are obtained do not include any foreign matter images. A quality judgment device uses the difference processing reflected light images obtained by a difference processing circuit and conducts a quality judgment. As described above, since difference processing reflected light images do not include any foreign matter images, a quality judgment device does not receive any influence from the foreign matter that is adhered to the protective glass and can conduct an excellent evaluation of the welding quality.
    • 差分处理电路实时接收由CCD照相机拍摄的焊接图像的输入,然后区分记录在存储器中的电力监视图像与焊接图像,以获得差分处理反射光图像。 由于由差分处理电路执行的差分处理,消除了包括在焊接图像和功率监视图像中的异物图像,并且获得的差分处理反射的光图像不包括任何异物图像。 质量判断装置使用由差分处理电路获得的差分处理反射光图像,并进行质量判断。 如上所述,由于差分处理反射光图像不包括任何异物图像,因此质量判断装置不会受到附着在保护玻璃上的异物的影响,并且可以进行焊接质量的良好评价。
