摘要： In a method of manufacturing an optical medium, an extended optical conductor containing active substance is formed to a predetermined shape by the use of resin by repeatedly folding or winding the optical conductor. A laser light beam or an amplified light beam is outputted from an edge portion of the optical conductor by absorbing an excitation light beam incident from the side surface of the optical conductor into the active substance through the resin. Thermoplastic resin is used as the resin. The thermoplastic resin transmits the excitation light beam. The resin is heated up to a glass transition temperature or higher. The optical conductor and the resin are bonded to each other so as to constitute a predetermined shape. The resin is cured.

摘要： An image forming apparatus includes a charge roller rotatable in contact with the surface of an image carrier to thereby charge the surface. The charged surface of the image carrier is exposed imagewise for forming a latent image. A developing device develops the latent image to thereby form a corresponding toner image. The toner image is transferred to a recording sheet. The charge roller is formed of a core and an elastic body affixed to the periphery of the core. Stearic acid to be added to rubber, which is the major component of the elastic body, is selected to be 1 wt % or less. An AC current value to be applied to the core is selected to be 1.1 mA or less. The image carrier is free from defective charging ascribable to impurities to deposit on the charge roller.

摘要： A motion compensated prediction interframe coding system which first measures characteristics regarding the fineness of a pattern or texture of a picture, which is represented by an input television signal and is divided into a group of continuous blocks each quantized by using a quantization step size, and changes the quantization step size into a smaller one if quantizes a block having a picture pattern or texture finer than patterns of the other blocks. Thereby, an amount of generated codes can be limited but a motion compensated prediction frame coding operation can be performed without degrading the fineness of the texture of the original input picture.

摘要： An image forming apparatus includes a recording head, a conveyance belt, a reverse passage, and a charger. The belt is looped around at least two rollers to adhere a recording medium thereto by electrostatic force and convey the medium. The belt defines a normal conveyance area in which the medium is conveyed in a first direction with the medium facing the head. The reverse passage sends the medium back again to a portion of the belt upstream from the head in the first direction. The reverse passage includes an opposite conveyance area of the belt in which the medium is conveyed in a second direction and a bypass passage to guide the medium separated from the opposite conveyance area toward the normal conveyance area. The charger is disposed between the bypass passage and an outer surface of the belt to charge the outer surface of the belt.
