    • The accuracy of focus adjustment operation is enhanced further. When focus adjustment operation is performed, a first measured distance acquired by utilization of TTL-AF and a second measured value acquired by utilization of a distance between the eyes have been computed in advance. The degree of reliability of the first measured distance is compared the degree of reliability of the second measured distance in accordance with a result of a determination as to whether or not a face is detected (S10), a result of a determination as to whether or not an ambient brightness value Br is equal to or less than a reference value (S12), a result of a determination as to whether or not a focal length “f” is equal to or less than a reference value (S16), and a result of a determination as to whether or not a second measured distance De is less than a first measured distance Dt (S18). Focus adjustment operation is performed in accordance with a measured distance determined to be more reliable.
    • 焦点调整操作的精度进一步提高。 当执行焦点调整操作时,预先计算通过利用TTL-AF获得的第一测量距离和通过利用眼睛之间的距离获得的第二测量值。 将第一测量距离的可靠度与第二测量距离的可靠度进行比较,该距离是根据关于是否检测到脸部的确定结果(S10),确定是否 或者不是环境亮度值Br等于或小于参考值(S12),关于焦距“f”是否等于或小于参考值的确定的结果(S16) ,以及第二测量距离De是否小于第一测量距离Dt的确定结果(S18)。 根据被确定为更可靠的测量距离执行对焦调整操作。

    • A line condition data collecting system for a telephone exchange includes an image memory in a central processing unit which stores line condition data to reduce the amount of time the central controller in the central processing unit waits for the line condition data. A signal receiving memory in the telephone exchange stores the line condition data and is sequentially accessed by an image memory controller autonomously from the central controller in the central processing unit. When the central controller requires line condition data, the image memory is checked and if the line condition data stored therein is valid, it is supplied to the central controller. If the line condition data in the image memory is invalid, a conventional access request is made to the signal receiving memory, but this occurs less frequently than in a conventional system.
    • 用于电话交换机的线路条件数据收集系统包括中央处理单元中的图像存储器,其存储线路条件数据以减少中央处理单元中的中央控制器等待线路状况数据的时间量。 电话交换机中的信号接收存储器存储线路条件数据,并且由图像存储器控制器从中央处理单元中的中央控制器自主地顺序地访问。 当中央控制器需要线路条件数据时,检查图像存储器,并且如果存储在其中的线路条件数据有效,则将其提供给中央控制器。 如果图像存储器中的线条件数据无效,则对信号接收存储器进行传统的访问请求,但是这比常规系统中的频繁发生。

    • An door lifter for coke ovens is provided with a door lifting or lowering power actuator consisting of two hydraulic cylinders connected in series and in back-to-back relationship. In the case of the door removal, first one of the two hydraulic cylinders is actuated so that the hooks are made into engagement with the corresponding lug pieces of the door and when they have engaged, said one hydraulic cylinder is stopped and locked. Thereafter the other hydraulic cylinder is actuated so that the door is lifted to be removed from the oven. In order to reengage the door, the other hydraulic cylinder is reversely actuated so that the door is lowered by the same stroke as the lift stroke and then said one hydraulic cylinder is reversely actuated so that the hooks are disengaged from the lug pieces of the door. In the case of the prior art door lifter of the type having a single hydraulic cylinder for lifting or lowering the door in two steps or strokes, there must be provided a hydraulic control circuit which is very complex in construction and expensive, but the use of two hydraulic cylinders can considerably simplify the hydraulic control circuit.
    • 用于焦炉的门提升器设置有门提升或降低动力致动器,其由串联连接和背对背关系的两个液压缸组成。 在门拆卸的情况下,两个液压缸中的第一个被致动,使得钩与门的相应的凸耳片接合,并且当它们接合时,所述一个液压缸被停止和锁定。 此后,另一个液压缸被致动,使得门被提升以从烘箱中移出。 为了重新接通门,另一个液压缸被反向致动,使得门以与升程行程相同的行程下降,然后所述一个液压缸反向致动,使得钩与门的凸耳片脱离 。 在现有技术的具有用于以两步或中风提升或降低门的单个液压缸的门式升降机的情况下,必须提供一种在结构上非常复杂并且昂贵的液压控制回路,但是使用 两个液压缸可以大大简化液压控制回路。
