    Abstract: An AC adaptor has an AC plug having wider contact portions facilitating better contact despite the displacement. AC plug 3 of AC adaptor 3 has a pair of conductive blades 4, an end surface with the blades projecting with a substantially right angle, a first surface and a first rotary shaft on a first side surface. On a second side surface opposite to the first side surface, there are provided a second surface and a second rotary shaft. A first and second planar contact portions which are electrically connected respectively to a first and second conductive blades are configured respectively to project slightly from the surfaces of the first and second rotary shafts. On a circuit board in the case, there are provided conductive spring terminals 17 with projecting portions thereof making resilient contact with the first and second planar contact portions 15.

    Abstract: To provide cramp mechanism for cramping a disk medium (3) with an even cramp load without needing special process such as heating shrinkage fit, the cramp mechanism comprises a disk cramper (4) having an inside opening and a cramping part (A) for cramping the disk medium (3), a cylindrical wall provided on a spindle hub (2) having the same center axis with a spindle motor (7), and a cramp nut (5). The outside surface of the cylindrical wall is configured to make a clearance fit at a fitting part (B) with the inside opening of the disk cramper (4), and the inside surface of the cylindrical wall is made tapered and provided with screw threads. On condition that the disk cramper (4) is added with a pre-load for cramping the magnetic disk medium (3), the cramp nut (5) is screwed onto the spindle hub (2) engaging with the screw threads with a tightening force (C) so as to deform the fitting part (B) to make a close fit with the disk cramper (4).

    Abstract: A color image forming apparatus has a plurality of developing units each including a developing sleeve and storing a developer of particular color. The developing sleeve is located to face a photoconductive element or similar image carrier. When the supply of the developer from the developing sleeve to the image carrier begins or ends, a magnet brush formed on the sleeve by the developer is slowly brought into or out of contact with the image carrier. As a result, a load acting on the image carrier due to the brush contacting it is slowly applied and cancelled. This eliminates changes in the moving speed of the image carrier and thereby insures desirable image quality.

    Abstract translation: 彩色图像形成装置具有多个显影单元，每个显影单元包括显影套筒并且存储特定颜色的显影剂。 显影套筒位于面向感光元件或类似图像载体。 当显影剂从显影套筒向图像载体的供应开始或结束时，由显影剂形成在套筒上的磁刷缓慢地与图像载体接触或脱离接触。 结果，缓慢地施加和消除由于刷子与其接触而作用在图像载体上的负载。 这消除了图像载体的移动速度的变化，从而确保期望的图像质量。

    Abstract: A color electrophotographic copying process utilizing the Carlson process. A colored original to be copied is color-separated and read by a solid-state image pickup device. Color compensation or gradation compensation is carried out on the basis of the data read by the solid-state image pickup device. When the color compensation is effected, amounts of masking are determined on the basis of the data read by the solid-state image pickup device, and the color-separated latent images are partially erased in an area-modulating manner dependent on the determined amounts of masking with an eraser having a light-emitting dot array. When the gradation compensation is effected, the latent images are partially erased with the eraser in an area-modulating manner dependent on the determined amounts of masking, or an appropriate gradation reproduction curve is selected on the basis of the data read by the solid-state image pickup device.
