    • A method for determining the deterioration of a capacitor that increases the measurement accuracy to have an improved reliability is disclosed. In this method for determining the deterioration of a capacitor, the deterioration of a capacitor including a pair of electrode bodies and electrolytic solution provided between the electrode bodies is determined by applying an AC voltage to the capacitor to measure an impedance characteristic at a frequency of the AC voltage. An inflection point appearing in the impedance characteristic due to the deterioration of the electrolytic solution is previously calculated to make comparison with an impedance value in the frequency region lower than the inflection point, thereby determining the deterioration.
    • 公开了一种用于确定提高测量精度以提高可靠性的电容器劣化的方法。 在确定电容器劣化的方法中,通过向电容器施加AC电压来确定包括一对电极体和设置在电极体之间的电解液的电容器的劣化,以测量电容器的频率处的阻抗特性 交流电压。 预先计算由于电解液的劣化而出现在阻抗特性中的拐点,以便与低于拐点的频率区域中的阻抗值进行比较,从而确定劣化。

    • A crossed roller rolling contact bearing assembly includes a pair of first and second members which move relative to each other, a guide channel defined between the first and second members and a plurality of rollers provided in the guide channel in a crossed arrangement with a spacer interposed between any two adjacent rollers. The spacer has a generally spherical outer peripheral surface and a pair of recessed, arc-shaped guide surfaces which have generatrix lines extending perpendicular to each other. Becuase of the spherical outer shape of the spacer, a generally wedge-shaped space is defined between the roller and the spacer so that a quantity of lubricant may be reserved therein to keep the guide channel sufficiently lubricated at all times.
    • 交叉滚子滚动接触轴承组件包括一对相对于彼此移动的第一和第二构件,限定在第一和第二构件之间的引导通道和设置在引导通道中的多个辊子,其间隔开间隔开 在任何两个相邻的辊之间。 间隔件具有大致球形的外周表面和一对具有垂直于彼此延伸的母线的凹入的弧形引导表面。 作为间隔件的球形外形,在辊和间隔件之间形成大致楔形的空间,以便可以保留一定数量的润滑剂以始终保持引导通道的充分润滑。
