摘要： A heat roll for electrophotography of a surface heating type having a heating resistor is arranged such that a bonding layer, an insulating layer, a resistance layer, and a surface insulating layer are consecutively provided on an outer surface of a hollow cylindrical core, and a bearing member for fitting with a bearing is fitted at each opposite end of the heat roll. A pipe or a round bar formed of aluminum, an aluminum alloy, copper, a copper alloy, or the like which has a greater coefficient of thermal conductivity than that of mild steel is disposed inside the core to permit a uniform distribution of the temperature. In addition, a gap of 0.2 mm or more is provided between the inner surface of the core and an outer peripheral surface of the member formed of the high-temperature conductive material. As a result, effects that are attributable to a difference in the coefficients of thermal conductivity can be alleviated, and a temperature rise of the heat roll up to a predetermined temperature can be accelerated.

摘要： This invention provides a method for producing an oxide superconductor which has a uniform texture and is markedly high in sintered density and current density.The method involves the formation of intermediate products from the starting materials. The intermediate products are then used to form the final product. Specifically, to form an oxide superconducting material having a compositional formulaYBa.sub.2 CU.sub.3 O.sub.7-8,where 8 is more than zero but less than 0.5, the method of the invention includes forming a first intermediate product of Y.sub.2 CU.sub.2 O.sub.5, forming a second intermediate product of BaCuO.sub.2, mixing the first and second intermediate products, and sintering the intermediate product mixture to form the oxide superconducting material.

摘要： A method and an apparatus for recording an image is disclosed, in which toner is supplied between a conductive recording drum covered with an insulating material and recording electrodes with the forward end thereof with a small gap from the drum and inclined at a great angle upstream of the direction of rotation of the recording drum. A toner carriage force is generated in the toner to flow out downstream by rotation of the recording drum. A permanent magnet is arranged in the recording drum to form a toner chain inclined at a great angle downstream of the recording drum from the forward end of the recording electrodes. The component of the magnetic force of the magnet in the direction of drum movement is balanced with the toner carriage force. Upon application of a recording voltage to the recording electrodes under this condition, the toner of the most downstream toner chain in contact with the drum surface develops a force of adhesion to the recording drum so that the drum rotates downstream with the toner attached thereon, thus forming an image due to the toner on the recording drum.
