摘要： One page of image data is divided into six data streams of blocks data. First to sixth FIFO memories of a speed difference absorbing circuit absorb a difference between a transfer rate of the block data and a processing speed of the subsequent circuits. FIFO memories of a line delay circuit delay the respective block data such that delay times for the respective block data change step by step by a predetermined time. An order conversion circuit produces 4-line parallel image data by sequentially selecting the block data sent from the line delay circuit. Sync signals for the four respective lines are delayed step by step by a predetermined time.

摘要： A density controlling method for controlling the density of toner applied to the surface of a photosensitive drum of a photocopying machine is disclosed herein. A small area of the drum is irridated with light, and toner is applied thereon. A photo-transistor sensor senses the density of the toner, and a signal produced by the sensor is compared to a reference signal indicative of optimal toner density. The difference signal is then applied through a CPU to control both the bias voltage of the developing system and the speed of the toner motor.

摘要： Embodiments of the present invention help allow accurate control of the magnetization reversal in a magnetic recording layer in small reversal units, whereby high-density recording can be achieved. According to one embodiment, by forming an intermediate layer having a granular structure similar to that of the magnetic recording layer below the magnetic recording layer, a continuous crystal grain boundary is formed at the interface between the magnetic recording layer and the intermediate layer, thereby preventing incomplete formation of the crystal grain boundary found in the initial growth layer of the magnetic recording layer. The intermediate layer comprises a non-magnetic alloy comprising Co and Cr as its main components and an oxide such as Al, Cr, Hf. Mg, Nb, Si, Ta, Ti and Zr. Further, the average content of the oxygen element in the intermediate layer is in the range from 6 at % to 20 at %.

摘要： Embodiments in accordance with the present invention provide a perpendicular recording medium with low noise and high recording density by reducing the effects from noise generated from the vicinity of the interface with the intermediate layer of the recording layer, in a perpendicular recording medium utilizing a granular recording layer containing oxygen or oxide additive in a cobalt-chromium alloy formed on an intermediate layer with a ruthenium or ruthenium alloy layer. A first recording layer and a second recording layer are formed in order on an intermediate layer of ruthenium or ruthenium alloy. The first recording layer and the second recording layer are comprised of cobalt as the main material in a granular structure containing chromium and oxygen. The saturation magnetization of the first recording layer is lower than the saturation magnetization of the second recording layer. When a first recording layer saturation magnetization is set as Ms1 (emu per cubic centimeter), a second recording layer saturation magnetization is set as Ms2 (emu per cubic centimeter), and the first recording layer film thickness is set to t1 (nm), then (Ms2−Ms1)×t1 will be larger than 0 (memu per square centimeter) and smaller than 0.15 (memu per square centimeter).

The intermediate film includes at least two layers, i.e., an oxygen-containing layer, or a nonmetallic element-containing layer containing nitrogen, silicon or carbon, and a metallic layer formed on a surface side of the oxygen-containing layer or the nonmetallic element-containing layer. The metallic layer includes a plurality of isolated island-shaped structures. Crystal grains of the perpendicular magnetization film are formed so as to correspond to the isolated island-shaped structures. As a result, a high recording density is obtained.
