    • An image forming apparatus provided with an image forming part capable of reproducing on a recording medium an image information frame recorded on a microfilm. The apparatus effects a decision as to whether or not image information is present within the range of a prescribed width inwardly of the edge of the image information frame. When the presence of the image information in the range mentioned above is discerned, the part of the projected light reaching the image forming part which falls outside the edge is intercepted and the image information within the image information frame is completely reproduced on the recording medium. When the absence of the image information in the aforementioned range is confirmed, the part of the projected light which falls outside the edge and within the range of the prescribed width inwardly of the edge is intercepted so that the background part of the negative film is not reproduced on the recording medium. The position of the edge of the image information frame is discerned by the fact that the density of the projected light is automatically detected with a sensor while the light is en route to the image forming part. During the detection of the position of the edge of the image information frame, the detection of the density of the projected light is performed outwardly from the central part of the image information frame.
    • 一种具有能够在记录介质上再现记录在缩微胶卷上的图像信息帧的图像形成部件的图像形成装置。 该装置对图像信息帧的边缘内部的规定宽度的范围内是否存在图像信息进行判定。 当识别到上述范围中的图像信息的存在时,到达图像形成部分落在边缘外侧的部分投射光被截获,图像信息帧内的图像信息在记录介质上被完全再现。 当确认了上述范围内的图像信息的不存在时,在边缘内侧落入规定宽度的范围内的投影光的一部分被截取,使得底片的背景部分不是 在记录介质上再现。 通过以下事实来识别图像信息帧的边缘的位置:当光线到达图像形成部分时,由传感器自动检测投射光的密度。 在检测图像信息帧的边缘的位置期间,从图像信息帧的中心部分向外执行投影光的浓度的检测。

    • There is disclosed an automatic exposure control device for use in a reader-printer which controls the amount of exposure in accordance with outputs of photodetectors arranged in an optical path. Each photodetector is connected to a comparator which is supplied with comparison voltage through changes of the comparison voltage stepwise. The control device changes the amount of variation per step of comparison voltage in accordance with a change of the type of film to the positive or to the negative, and limits the photodetectors to be used for controlling only to the photodetectors being capable of receiving the light of micro film image.
    • 公开了一种在读取器 - 打印机中使用的自动曝光控制装置,其根据布置在光路中的光电检测器的输出来控制曝光量。 每个光电检测器连接到比较器,该比较器通过逐步改变比较电压而提供比较电压。 控制装置根据薄膜类型的变化将比较电压的每一步的变化量改变为正或负,并限制用于仅控制能够接收光的光电检测器的光电探测器 的微电影图像。

    • A rotor of a rotating electric machine includes a cylindrical rotor core, a plurality of coil slots provided on an outer periphery of the rotor core along a rotor axis direction, rotor coils disposed in the coil slots by laminating a plurality of field conductors through an insulation material, a rotor wedge disposed at an opening end portion of the coil slot so as to support the rotor coil, a coil ventilation duct formed in the coil slot so as to pass through the rotor coils, the rotor wedge and the insulation material, and sub-slots provided at bottom portions of the coil slots so as to be communicated with rotor core ends and the coil ventilation ducts. In such a rotor of a rotating electric machine, the coil slot, the sub-slots and the coil ventilation duct constitute a cooling gas channel for distributing a cooling gas to thereby cool the rotor coils. A depth in a diameter direction of each sub-slot from the rotor coil end to a nearest coil ventilation duct is larger than a depth of the sub-slot at a portion near a center of the rotor core.
