    • A digital camera capable of accurately detecting flicker even while a video image is displayed on a display device is provided. In a digital camera, a video image is displayed on a display device 40 serving as a viewfinder for photographing based on a display video signal supplied from a CMOS image sensor 120 while image data based on a recording video signal supplied from the CMOS image sensor 120 is recorded in a recording unit 50. The digital camera detects flicker based on a video signal supplied from a group of pixel circuits which do not supply the display video signal among the group of pixel circuits forming the CMOS image sensor 120.

    • A weft picking system for an air jet loom is provided with a microcomputer as a controller. The weft picking system comprises a weft traction device including a pair of rollers, one of which is driven by an inverter motor. A weft yarn fed from a weft measuring and storing device can be placed between the rollers to be drawn toward a weft posture regulating nozzle. The weft posture regulating nozzle is arranged to project the weft yarn into the shed of warp yarns and regulates the posture of the weft yarn under the influence of air jet ejected from the nozzle and from a plurality of sub-nozzles. The rollers always rotate during a weaving operation of the loom. A change-over device is provided to change the weft yarn from a first state of being placed between the rollers to a second state of separating from the rollers or vice versa. A weft yarn slackened portion is unavoidably formed between the weft traction device and the weft posture regulating nozzle, due to a temporary difference in the tractive speed between the weft posture regulating nozzle and the weft traction device. A slackened portion deforming device is disposed between the weft traction device and the weft posture regulating nozzle to effectively deform the slackened portion in a manner to smoothen the slackened portion enough as to prevent any trouble in the weaving operation and any defects in the woven fabric.
    • 用于喷气织机的纬纱拾取系统设置有作为控制器的微型计算机。 纬纱拾取系统包括一个包括一对辊的纬纱牵引装置,其中一个由逆变器马达驱动。 从纬纱测量和存储装置输送的纬纱可以放置在辊之间,以朝着纬纱姿势调节喷嘴拉伸。 纬纱姿势调节喷嘴布置成将纬纱投射到经纱梭口中,并且在喷嘴和从多个副喷嘴喷射的空气喷射的影响下调节纬纱的姿态。 滚筒总是在织机的织造操作期间旋转。 提供转换装置以将纬纱从放置在辊之间的第一状态改变到与辊分离的第二状态,反之亦然。 由于纬纱姿势调节喷嘴和纬纱牵引装置之间的牵引速度的暂时差异,纬纱牵引装置和纬纱姿势调节喷嘴之间不可避免地形成纬纱松弛部分。 在纬纱牵引装置和纬纱姿势调节喷嘴之间设置有松弛部分变形装置,以有效地使松弛部分变形,以使松弛部分平滑,足以防止织造操作中的任何麻烦和机织织物中的任何缺陷。
