    • A camera with built-in motor having a motor disposed horizontally at the central bottom portion of the camera body and out of path of the input light for driving various drive mechanisms necessary for the photographing. Said motor has two output shafts extending out of the housing of the motor, so that two or more loads may be simultaneously driven by the motor. Said mechanisms are suitably sorted into groups by the magnitudes of the loads imparted by these mechanisms, and these groups are driven by the motor in such a sequence as to maintain a substantially constant level of load on the motor in relation to time.
    • 具有内置电动机的照相机具有水平设置在照相机主体的中央底部并且不在输入光路径外的电动机,用于驱动拍摄所需的各种驱动机构。 所述电动机具有两个从电动机外壳延伸的输出轴,从而可以由电动机同时驱动两个或更多个负载。 所述机构通过由这些机构施加的载荷的大小适当地分组成组,并且这些组由马达驱动以使得马达相对于时间维持基本恒定的载荷水平。

    • An electromagnetic wave amplifier and an electromagnetic wave generator operate using electron beams in a vacuum environment. The amplifier, arranged in a vacuum environment, comprises an electron emitting section for emitting electron beams and an amplifying section for amplifying an inputted electromagnetic wave in one direction by utilizing energy received from an electron beam emitted from the electron emitting section and traveling in the vacuum along a dielectric waveguide having a wave-shaped form. The generator, also arranged in a vacuum environment, comprises an electron emitting section for emitting electron beams and an oscillating section for generating an electromagnetic wave by utilizing electron beams emitted from the electron emitting section and travelling in the vacuum along a dielectric waveguide having a composite wave-shaped form.
