    • An induction heating device for inductively heating an object to be heated which is formed of conductive material has a holder. The holder is positioned outside the object. The device has an exciting coil for inductively heating the object. The exciting coil is supported by the holder. The exciting coil is composed of a plurality of turns of conductor forming a layer, which is positioned along the object. The device also has a demagnetizing coil which is positioned along the layer of the exciting coil. In the demagnetizing coil, a back electromotive force is induced in accordance with a magnetic field produced by the exciting coil, so as to cancel the magnetic field. Stability in the temperature control for the object such as a heating roller can be improved by effective function of the demagnetizing coil. The device can be miniaturized and configured at low cost.
    • 用于感应加热由导电材料形成的被加热物的感应加热装置具有保持器。 支架位于物体外部。 该装置具有用于感应加热物体的励磁线圈。 励磁线圈由支架支撑。 励磁线圈由形成层的导体的多个匝组成,沿着物体定位。 该装置还具有沿着激励线圈的层定位的去磁线圈。 在去磁线圈中,根据由励磁线圈产生的磁场感应出反电动势,以抵消磁场。 可以通过退磁线圈的有效功能来提高对加热辊等物体的温度控制的稳定性。 该设备可以以低成本小型化和配置。

    • An apparatus is provided with a movable cartridge casing capable of facilitating film cartridge loading and unloading operations. In a loading operation, the cartridge casing is positioned at a cartridge receiving position outside the body of the apparatus so that the film cartridge can easily be inserted in the cartridge casing, the cartridge casing containing the film cartridge is pushed into the body to an intermediate position where the film spool of the film cartridge is separated from a spool driving shaft, and then the cartridge casing is moved toward the spool driving shaft along a line substantially parallel to the axis of the spool driving shaft to bring the film spool into engagement with the spool driving shaft. In an unloading operation, the cartridge casing is moved away from the spool driving shaft to the intermediate position along the line substantially parallel to the axis of the spool driving shaft to separate the film spool from the spool driving shaft, and then the cartridge casing is moved to the cartridge receiving position outside the body.
    • 一种装置设置有能够促进暗盒装载和卸载操作的可移动的盒壳体。 在装载操作中,盒式壳体被定位在设备主体外部的盒接收位置处,使得暗盒可以容易地插入盒壳体中,将包含暗盒的盒壳被推入到中间体 胶片暗盒的胶片卷轴与卷轴驱动轴分离的位置,然后盒壳体沿着基本上平行于卷轴驱动轴的轴线向卷轴驱动轴移动,以使胶片卷轴与 阀芯驱动轴。 在卸载操作中,盒壳体沿着基本上平行于卷轴驱动轴的轴线的线路从卷轴驱动轴移动到中间位置,以将胶卷卷轴与卷轴驱动轴分离,然后盒壳体 移动到身体外部的墨盒接收位置。
