Abstract: The image forming apparatus can retain a stable and high image quality for many hours without use of any high precise mechanical parts and without causing any non-uniformity and mal-registration in a color image. In the image forming apparatus, an image recording medium (photosensitive drum) (6a) is driven by a rotative driving mechanism (pulleys and belts) (40a); and an image recording section (print bar) (6c) records an image repeatedly on the rotating image recording medium (6a) in a direction perpendicular to a rotational direction of the image recording medium. The image recorded on the image recording medium (6a) is transcribed onto an image transcribing medium (paper) (22) being fed in the rotational direction of the image recording medium (6a) to form an image.

Abstract: An industrial robot apparatus comprise for controlling an industrial robot and a peripheral unit thereof according to a program so as to load workpieces on a pallet, an abnormal stop unit for detecting an abnormality which occurs in at least either of the industrial robot and the peripheral unit and for stopping both the industrial robot and the peripheral unit, a storage unit for storing a step of the program which is being executed when the abnormal stop takes place, and a removal unit for removing remaining workpieces to be loaded on the pallet in steps following the stored step of the storage unit.

Abstract: A rotary anode X-ray tube comprises a support frame disposed inside a glass bulb, a rotary anode fixed to a shaft portion of the support frame, a rotating shaft attached to the support frame coaxially with the shaft portion, a support member having a cylindrical portion concentrically surrounding the rotating shaft at a given space therefrom, a double tube concentrically disposed between the rotating shaft and the cylindrical portion and fixed to the cylindrical portion, first and second bearings concentrically disposed between the auxiliary tube and the rotating shaft at given spaces therefrom, and a coil spring for elastically pressing one race of one of the bearings along said rotating shaft, the other race of which is fixed.
