Abstract: An LED print head is arranged opposite to a photosensitive body, consisting of a base body, which is arranged parallel to the axis of the photosensitive body and consists of a large volume base part having an upper face opposite to the photosensitive body and a small volume projection part extending upward from a part of the upper face of the base part, and having a narrow width in the path of the photosensitive body. An LED base panel is fitted on the upper face of the base part, and a lens array is on the part of a side of the projecting part, being arranged between the opposing face of the photosensitive body, and the upper face of the LED base panel. Manufacturing and attaching methods relating to the print head are also disclosed.

Abstract: A motor comprising: a rotor which is supported via a rotating shaft in a radial direction of the rotating shaft, the rotating shaft being disposed around a fixed shaft provided on the side of a stator to form a dynamic-pressure bearing; a stator-side thrust magnet disposed in the stator so as to support the rotor with respect to the stator in a thrust direction of the rotating shaft; a rotor-side thrust magnet disposed in the rotor; and a rotating main body portion mounted to the rotating shaft of the rotor and formed integrally by a resin magnetic material, in which a main magnet portion, an FG magnet portion for generating a speed-of-rotation detecting pulse, and a rotor-side thrust magnet portion serving as said rotor-side thrust magnet are respectively polarized at predetermined positions in the rotating main body portion.

Abstract: The invention is applied to a developing device having a cylindrical toner carrying body. The cylindrical toner carrying body includes a cylindrical electrically conductive inner layer and a cylindrical semiconductor outer layer. The surface potential at the semiconductive outer layer is controlled by power supplies connected to the electrically conductive inner layer, so that particles of a single-component toner charged by friction can adhere to the semiconductive outer layer surface. In such a developing device having the thus constructed toner carrying body, the electrically conductive inner layer is formed of a cylindrical sleeve made of an electrically conductive metallic material, and the semiconductive outer layer not only is formed of a semiconductive resin layer coated on the outer peripheral surface of the cylindrical sleeve but also has uniform irregularities on its surface.

Abstract: In connecting a bow of a pusher boat having a driving power source with a stern of a barge having no driving power source at a recessed portion formed at the stern of the barge, a plurality of freely projectable connecting pins provided at positions in the vicinity of center part of both sides as well as at the bow of the pusher boat are inserted into connecting pin receiving ports formed at corresponding positions in the recess of the barge so as to make both pusher boat and barge to be unified into a single navigable body, and the connecting pins at both sides of the pusher boat and the connecting pin receiving ports provided at the recessed portion at the stern of the barge are arranged in a backward obliquity, or swept back direction, with respect to the lengthwise direction of the boat hull.
