摘要： According to this invention, since black regions are provided along the advancing direction on an original plate, the dark-time output levels of the linear sensor would not be affected by dust adhered on the original plate or the presence of trimming lines. Since a calibration region is provided, the circuit system can be calibrated with the maximum and minimum values of the signals from the linear sensor to thereby achieve more precise reading of images.

摘要翻译： 根据本发明，由于在原版上沿着前进方向设置黑色区域，因此线性传感器的黑暗时间输出水平将不受附着在原版上的灰尘或修剪线的存在的影响。 由于提供了校准区域，所以可以利用来自线性传感器的信号的最大值和最小值校准电路系统，从而实现图像的更精确的读取。

摘要： The non-volatile memory device comprises a memory cell array, a block decoder, and a decode signal reading section. The memory cell array has a plurality of cell blocks. Each of the cell blocks is composed of a plurality of memory cells arranged roughly into a matrix pattern. Each memory cell has a floating gate to or from which electrons are injected or extracted to write or erase data. The block decoder receives a block address, and outputs a decode signal to select a cell block corresponding to the block address from the cell blocks. The memory cells of the selected block are erased simultaneously. When a control signal is inputted to the block decoder, the block decoder outputs the decode signal to select all the cell blocks for erasure of the memory cells of all the cell blocks simultaneously, irrespective of the block address. The decode signal reading section outputs the decode signal to the outside. The decode signal is applied to the cell blocks and in parallel to the decode signal reading section itself and further outputted to the outside therethrough. In the memory device, the block erase function can be checked at a short time and additionally the other functional blocks can be checked simply.

摘要： A memory cell array is divided into a plurality of blocks. In altering data for a block (selected block), a moderating voltage is applied to the source or control gate of a memory cell in another block (non-selected block) to moderate stress between the floating gate and source/drain, thereby preventing write error and erase error. In the program operation, the source and drain of a memory cell in the non-selected block are equalized to moderate an electric field between the control gate and source/drain and not to flow a channel current, thereby preventing write error. In carrying out a negative voltage erase method, prior to setting the source line and word line of a cell in a non-selected block to an erase voltage, the source and word lines are equalized. The equalization operation is released after the erase operation, thereby preventing malfunction of a non-selected cell.

摘要： Source and drain regions of a second conductivity type are formed in a stripe form in the surface area of a semiconductor substrate of a first conductivity type. A first insulation film is formed on the source and drain regions of the substrate. A second thin insulation film having a tunnel effect is formed on that part of the substrate which lies between the source and drain regions. A floating gate is formed on the second insulation film. A third insulation film is formed on the first insulation film, the floating gate and that part of the substrate which lies between the source and drain regions and on which the second insulation film is not formed. A control gate is formed on the third insulation film in a stripe form extending in a direction which intersects the source and drain regions. An impurity region of the first conductivity type having an impurity concentration higher than the substrate is formed in the substrate except the source and drain regions and the portions lying below the control gate. A floating gate transistor is constituted to include the substrate, source and drain regions, second insulation film, floating gate, third insulation film and control gate. An offset transistor is constituted to include the substrate, source and drain regions, third insulation film and control gate. The first insulation film and the impurity region are used as an element isolation region of a memory cell.

摘要： A method and process for processing picture image signals detects color separation signals of a color original image and then respectively converts these color separation signals into digital color separation signals. These digital color separation signals are then multiplied by predetermined coefficients and the results of these multiplications are sequentially accumulated for equalizing the levels of the digital color separation signals at a grey point of the original image so as to thereby obtain digital color separation signals which are converted to equivalent neutral densities. Hue signals of yellow, green, cyan, blue, magenta, and red which divide a color space into six hues are obtained from the digital color separation signals which are converted to the equivalent neutral densities. The hue signals are multiplied by predetermined color correction coefficients and the results thereof accumulated for color correction signals on yellow, magenta, and cyan. The digital color separation signals which are converted to the equivalent neutral densities are added to the color correction signals so as to thereby obtain selective color correction signals for recording the original image.

摘要： In a method for scanning a color fiber optic tube of an electron gun type in which a screen is formed by a plurality of band-shaped phosphors providing different illuminant colors, usually red, green and blue, respectively, an electron beam from the electron gun is deflected vertically in a lateral direction of the phosphors and horizontally in a longitudinal direction thereof. The vertical deflection of the electron beam is time controlled in response to the sensitivity of a photo-sensitive material disposed to the fiber optic tube. In another aspect, the horizontal deflection is performed by a stepped method in which the horizontal deflection is stopped during a time interval when one raster of the vertical deflection of the electron beam crosses the phosphors and progresses stepwisely when the vertical deflection is subsequently transferred to the next raster.
