摘要： A throttle control device includes a motor coupled to the throttle shaft, so that the throttle valve rotates to open and close an intake air channel as the motor is driven. A detection device serves to detect the degree of opening of the throttle valve and includes a pair of magnets and a sensor. The magnets are mounted to the throttle shaft via a magnet support and are positioned to oppose each other across the rotational axis of the throttle shaft in order to produce a uniform magnetic field. The sensor is mounted to the throttle body and serves to detect a direction of the magnetic field produced by the magnets, so that the detection device outputs a signal representing the degree of opening of the throttle valve.

摘要： There is a demand for preventing display quality of a display apparatus from deteriorating. When charged particles (9) are attracted to a first electrode (3), the distribution density may not become uniform over the entire area A1 and only the distribution density in the periphery of the first electrode (3) (see reference numeral A3) may be locally reduced. The present invention places a colored layer (5) having the same color as the color of charged particles in this area A3. Therefore, even if the distribution density is low, the low density is hardly visually recognized, making it possible to prevent the display quality from deteriorating.

摘要翻译： 需要防止显示装置的显示质量恶化。 当带电粒子（9）被吸引到第一电极（3）时，分布密度在整个区域A 1上可能不均匀，并且仅在第一电极（3）周围的分布密度（参见附图标记A3 ）可能会局部减少。 本发明在该区域A 3中设置与带电粒子的颜色相同颜色的着色层（5）。 因此，即使分布密度低，几乎不可视地识别低密度，从而可以防止显示质量恶化。

摘要： A sensor for a throttle control device. The throttle control device includes a throttle body. A throttle valve is disposed within an intake air channel defined within the throttle body. A speed or gear reduction mechanism is coupled between a motor and the throttle valve. A sensor detects the rotational position, i.e., the rotational angle, of the motor and has a movable section and a fixed sensing section. The movable section is attached to a rotary shaft of the motor, so that the movable section rotates as the rotary shaft rotates. The fixed sensing section is mounted to the throttle body and is disposed within the movable section. By detecting the rotation of the motor a computing section can accurately determine the degree of opening of the throttle valve. The sensor outputs the degree of opening of the throttle valve.
