摘要： A liquid crystal display, which displays images processed by a liquid crystal display control device, and a liquid crystal display control device are disclosed. The liquid crystal display displays two-dimensional images processed by the liquid crystal display control device, where the influence of surrounding pixels is reduced. A renewed pixel value corresponding to a first pixel is obtained by adding the result of the multiplication of the coefficient and the difference value of the first pixel value and the second pixel value in a computing block.

摘要： An apparatus installed in a molten metal plating line includes a blade pressed against a roll dipped in a molten metal plating bath, in which a metal strip travels. The apparatus removes substances deposited on a surface of the roll. The apparatus also includes an arm for supporting the blade, and a screw member disposed above the plating bath so as to traverse it and moving along an axis of the roll in the bath for removing substances deposited on the roll in the molten metal plating bath. Floats and/or weights are mounted on the arm so as to adjust a press force of the blade applied to the roll in the molten metal plating bath. A method for preventing the occurrence of dents on a molten-metal-plated steel strip using the apparatus is also disclosed.

摘要： A method of designing a logic circuit including pass transistors is disclosed. A logic group having a complementary variable in a given logical expression to be realized into the logic circuit is mapped using a multiplexer composed of a combination of the pass transistors. The number of transistors used in the logic circuit and the number of stages can be reduced by taking advantage of the multiplexer. When a logic circuit including both pass transistors and a multiple-input logic gate is designed, a logic group having a common variable in the given logical expression is mapped using the multiple-input logic gate. The number of transistors used in the logic circuit and the number of stages can be further reduced by taking advantage of the multiple-input logic gate. In order to ease the above mapping procedure, a complementary variable is identified and the given logical expression is optimized by grouping product terms of the logical expression by the complementary variable. Furthermore, a common variable is identified, and the logical expression is further optimized by grouping product terms of the logical expression by the common variable.

摘要： A grain-oriented electromagnetic steel sheet having a multiplicity of fine grains having a diameter of about 3 mm or less on the surface of the steel sheet, in a numerical ratio of about 65% or more and of about 98% or less relative to the constituting grains that penetrate the sheet along the direction parallel to its thickness, and a method for producing the same. The fine grains are artificially created and regularly disposed with a random orientation in the steel sheet, and contribute to decreasing the strain susceptibility of the steel. More preferably, a treatment for finely dividing magnetic domains is applied on the surface of the steel sheet. Transformers based upon the steel sheet have excellent magnetic characteristics (iron loss and magnetic flux density) together with strain resistance, and the steel sheet has good practical device characteristics (building factor) after being assembled into a transformer.
