    摘要: A driving apparatus and a driving method are disclosed that are capable of uniformly lighting each entire fluorescent tube irrespective of the length or number of fluorescent tubes when simultaneously driving a plurality of fluorescent tubes in a fluorescent tube lighting apparatus. When two inverter circuits having respective transformers are provided at both ends of a fluorescent tube to light the fluorescent tube by push-pull driving, feedback windings of transformers not used in self-excited oscillation of each inverter circuit are connected together, with the transformer connection that connects together the feedback windings being either in-phase or in opposite phase, and the method of connection for fluorescent tubes connecting to secondary windings of each transformer can be changed in accordance with that connection method.

    摘要: To compensate for uneven brightness in the longitudinal direction of fluorescent lamps of a backlight unit and achieve a display screen with an even brightness, a reflection unit of the backlight unit, the fluorescent tube surface of the fluorescent lamps or a diffusion unit is used to either reduce the reflectance, transmittance, or radiation brightness of the high-voltage side of the fluorescent lamps or increase the reflectance, transmittance, or radiation brightness of the low-voltage side thereof so as to compensate for uneven brightness of the illumination light and thereby ensure an even brightness. For example, dot pattern regions D1, D2 and D3, i.e., the regions whose density increases in stages, are imparted to the portion of a reflection layer 13 of the backlight unit with a relatively high brightness. As for the display device, on the other hand, the display image data supplied to a liquid crystal panel or the aperture ratio of the liquid crystal panel is controlled, for example, to compensate for uneven brightness in the longitudinal direction of the fluorescent lamps and ensure an even brightness.

    摘要: A sewing machine including a needle bar having a sewing needle, a spindle for driving the needle bar, a bed portion movable selectively to a using position or a retracted position, and a rotary hook housed in the bed portion. A stitch is formed by the cooperation of the sewing needle and the rotary hook. A rotary hook drive motor is provided in the bed portion for driving the rotary hook. A sensor is provided for detecting a position of the bed portion. The needle bar and the spindle is selectively disconnected from each other. If the bed portion is out of the using position, and this out position is detected by the sensor, the needle bar is released from the spindle for stopping the sewing needle. Further, in this case, the rotation of the rotary hook drive motor is also stopped.

    摘要: An embroidery machine having a plurality of beds and corresponding heads. In each of the heads, a plurality of needle bars supporting needles and thread take up levers are provided. Each bed contains a rotary hook drive motor provided independent of a sewing machine motor which drives a spindle extending through the heads. The rotary hook drive motor is driven in synchronization with the spindle for performing embroidery stitching, but is driven independently of the spindle at a specific rotation angle range thereof based on number of stitching. In each bed, a conventional needle thread holding mechanism is dispensed with. By controlling rotation of the rotary hook drive motor, a residual end part of the needle thread has a sufficient length capable of avoiding disengagement of the residual end part from an eyelet of the needle at a thread cutting operation.
