    • A wristwatch comprises a watch movement having an outwardly curved frame portion, and a micro motor mounted on the watch movement. The micro motor comprises a curved magnetic core, a coil wound on the magnetic core, and a stator connected to the magnetic core to define therewith a closed magnetic flux path and having an opening therein in which a rotor is rotatably disposed. The magnetic core is curved outwardly with a curvature similar to and conforming to that of the outwardly curved frame of the watch movement, and the curved magnetic core overlies the curved frame of the watch movement so that no wasted space exists therebetween. The stator comprises a pair of stator pieces each connected at one end to a respective end portion of the curved magnetic core and the stator pieces have curved side edge portions extending at least partly along the curvature of said curved mangetic core to thereby form a compact overall assembly.

    • A liquid refractometer comprising a light source unit, a probe unit and a detection unit. The light source unit generates a beam of polarized mixed light composed of two coherent light waves that have been linearly polarized in directions at right angles to each other. The probe unit contains a polarization separation portion, a sample holding portion, a reference portion and a beam mixing portion. The polarization separation portion separates the mixed light beam back into the two polarized waves and directs one of the beams through the sample portion and the other beam through the reference portion. The mixing portion re-mixes the two waves after having passed through the sample holding portion and the reference portion. The detection unit receives the re-mixed light and measures the refractive index differences between the liquid sample and the reference portion. Fiber optics optically connect the light source unit, the probe unit and the detector unit.
    • 一种液体折射计,包括光源单元,探针单元和检测单元。 光源单元产生由彼此成直角的方向线性极化的两个相干光波组成的偏振混合光束。 探针单元包含偏振分离部分,样本保持部分,参考部分和光束混合部分。 偏振分离部分将混合光束分离成两个偏振波,并将一个光束通过样本部分,另一个光束通过参考部分。 混合部分在通过样品保持部分和参考部分之后重新混合两个波。 检测单元接收再混合光并测量液体样品与参考部分之间的折射率差异。 光纤光学连接光源单元,探头单元和检测器单元。

    • The electronic metronome has a baton reciprocatingly driven by a pulse-drive stepper motor powered by a varying voltage source. Drive circuitry generates and applies drive pulses to the stepper motor, each drive pulse being composed of a plurality of individual pulses having a pulse width which varies in accordance with variations of the voltage source and with the selected tempo at which the baton reciprocates. The stepper motor is thus driven at a constant torque-frequency characteristic despite fluctuations in the power source voltage and the tempo of the metronome.
    • 电子节拍器具有由由变化的电压源供电的脉冲驱动步进电机往复驱动的指挥棒。 驱动电路产生驱动脉冲并向步进电机施加驱动脉冲,每个驱动脉冲由多个单独的脉冲组成,其脉冲宽度根据电压源的变化和所选择的速度在棒棒复原时变化。 因此,尽管电动机电压和节拍器的速度有波动,步进电动机也以恒定的转矩频率特性被驱动。
