    • Monochromatic light emitted from a monochromator is split into two light beams. These light beams are detected by a photodetector and converted into corresponding electric signals after having been transmitted, respectively, through a sample to be analyzed and a reference placed in the respective beam paths. The signal corresponding to the light beam transmitted through the sample and the signal corresponding to the light beam transmitted through the reference are converted into digital signals which are subsequently stored in respective digital storages or memories. The signal corresponding to the light beam transmitted through the reference is compared with a value in a predetermined range. The resultant value is then converted into an analog signal for operating a sensitivity regulator thereby to adjust the sensitivity of the photodetector. Thus, the signal corresponding to the light beam transmitted through the reference (reference light signal) is so controlled as to lie in a predetermined range. From the digital signals stored in the digital memory, ratio between the sample light signal and the reference light signal is arithmetically calculated by a digital processor unit for determining the transmittance of the sample. Since the reference light signal is prevented from significant variation and the calculation of the signal ratio is effected on the basis of digital technique, the measurement accuracy is remarkably enhanced.
    • 从单色仪发射的单色光被分成两束光束。 这些光束被光电检测器检测,并且在分别通过要分析的样本和放置在各个光束路径中的参考之后被转换成相应的电信号。 对应于通过样本传输的光束的信号和对应于通过参考的光束的信号被转换成数字信号,随后将其存储在相应的数字存储器或存储器中。 将与通过参考的光束相对应的信号与预定范围内的值进行比较。 然后将所得到的值转换成用于操作灵敏度调节器的模拟信号,从而调节光电检测器的灵敏度。 因此,通过参考(参考光信号)传输的光束对应的信号被控制在预定范围内。 从存储在数字存储器中的数字信号,采样光信号和参考光信号之间的比例由用于确定样品的透射率的数字处理器单元算术计算。 由于参考光信号被防止显着变化,并且基于数字技术来实现信号比的计算,所以测量精度显着提高。

    • A welding gun is provided in which moisture does not penetrate inside of a motor housing due to preventing the inside of the motor housing from becoming negative pressure. The welding gun includes a feed screw mechanism (40) that is coupled to a servo motor (10) and has a hollow rod (43) that reciprocally moves in a predetermined direction by way of torque applied by the servo motor (10), and a moveable electrode tip (62) that is connected to a leading end portion of the hollow rod (43) and opens and closes relative to a fixed electrode tip (61) according to the reciprocal movement of the hollow rod (43). The servo motor 10 has a motor housing (20) in which a motor housing hollow part (25) accommodating a portion of the hollow rod (43) to be reciprocally moveable is formed. A vent (21b) that ventilates the motor housing hollow part (25) with ambient air is formed in the motor housing (20).
