An apparatus for forming images on a photosensitive material of non-crystalline silicon where the deterioration of image quality from charge storage effects is reduced by charging the photosensitive material at a polarity opposite that of its initial charging prior to the image forming irradiation of photosensitive material.

A floating apparatus for use in an attractive floater railway includes a magnetic rail mounted on the underside of a track. The magnetic rail comprises sheets of ferromagnetic material laminated together and is formed to have a cross section in the shape of a trapezoid or a quadrant of a circle with faces of the rail including a horizontal surface and a vertical surface. A guiding electromagnet is disposed opposite to the vertical surface and a supporting electromagnet is disposed opposite to th...
