    • An angular sensor which enables to obtain an output signal proportional to a relative rotational angle with low manufacturing cost and with miniaturized size. An angular sensor which includes a first magnet and a second magnet fixed to a rotation body, magnetic flux sensing surface is fixed to the stator to be positioned in magnetic field between the first magnet and the second magnet and perpendicular to magnetic sensing direction for sensing a magnetic flux, a magneto-electric transducer element for outputting an electric signal corresponding to a magnetic sensing direction element of the magnetic density, deflection yokes. The deflection yokes are positioned facing the magnetic flux sensing surfaces. The deflection yokes are positioned within a range of three quarters of a distance between the first magnet and the second magnet in X-axis direction and one half of a distance between the first magnet and the second magnet in Y-axis direction.
    • 一种角度传感器,其能够以低制造成本和小尺寸的尺寸获得与相对旋转角度成比例的输出信号。 一种角度传感器,其包括固定到旋转体的第一磁体和第二磁体,磁通检测表面固定到定子,以定位在第一磁体和第二磁体之间的磁场中,并且垂直于磁感应方向,用于感测 磁通量,用于输出对应于磁密度的磁感测方向元件的电信号的磁电换能器元件,偏转轭。 偏转轭定位成面对磁通量感测表面。 偏转轭位于第一磁铁和第二磁体之间的距离为X轴方向的四分之三的范围内,第一磁铁与第二磁体之间的距离为Y轴方向的一半。

    • A line-illuminating device which is resistant to shrinkage problems caused by repetition of heating and cooling includes a white casing made of polycarbonate or the like, a light guide made of an acrylic resin or the like and accommodated in the casing such that the light-emitting surface thereof is exposed, and light-emitting elements (for example, light-emitting diodes) as a light source provided on both ends of the casing so as to abut against the end surfaces of the light guide without a gap. The casing is divided into two portions in the longitudinal direction, and a gap is formed between the two divided portions. With this gap, even if the light guide shrinks due to repetition of heating and cooling, the divided portions can effectively shrink together with the light guide via the gap, and the abutting state between the end surface of the light guide and the light-emitting element can be maintained.
    • 耐受重复加热和冷却所引起的收缩问题的线路照明装置包括由聚碳酸酯等制成的白色壳体,由丙烯酸树脂等制成并且容纳在壳体中的导光体, 露出发光面,将作为光源的发光元件(例如发光二极管)设置在壳体的两端,以便与导光体的端面邻接而没有间隙。 壳体沿长度方向分为两部分,并且在两个分割部分之间形成间隙。 由于该间隙,即使由于重复加热而导致光导收缩,所以分割部分能够经由间隙与导光体一起有效地收缩,并且导光体的端面与发光的接触状态 元素可以维护。
