Abstract: Sub pits are suppressed from branching in a surface layer of an aluminum foil, and an electrode foil for an aluminum electrolytic capacitor with a large electrostatic capacitance and a method of manufacturing the same are provided. A large number of main pits are formed by etching on both surfaces of the aluminum foil to extend from the surfaces in a thickness direction of the foil, sub pits are formed to branch away from the main pits for a range from a vicinity of a surface layer portion of each main pits excluding the surface layer portion, to inner ends of the main pits. Since the sub pits are not formed in the surface layer of the aluminum foil, the sub pits can be increased in density effectively to the electrostatic capacitance, allowing the electrode foil for the aluminum electrolytic capacitor to have high mechanical strength and high electrostatic capacitance.

Abstract: A liquid crystal display system which can accept input display data having a resolution which is larger (e.g. 1120×780 dots) or smaller (e.g. 640×480 dots) than a resolution of a liquid crystal panel (e.g. 1024×768 dots), and convert the input display data to reduced or enlarged display data for display on the liquid crystal panel. The system generates, for example, one new vertical or horizontal line based on two contiguous vertical or horizontal lines in the input display data. If the resolution of the input display data is larger than the resolution of the liquid crystal panel, the system replaces the two contiguous lines with the one new line. If the resolution of the input display data is smaller than the resolution of the liquid crystal panel, the system inserts the one new line between the two contiguous lines.

Abstract: A liquid crystal display system which can accept display data having a resolution different from that of a screen for the liquid crystal display and display the display data. For example, a CPU outputs display data of 1120×780 dots and a liquid crystal panel has a 1024×768-dot resolution which is smaller than the display data resolution. The display screen of the liquid crystal panel comprises a linear arrangement of pixels. A data conversion section generates display data for a new horizontal or vertical line based on display data for two horizontal or vertical lines contiguous to each other and repeats replacement of display data of the two lines with the display data of the one line for reducing the number of horizontal lines of one screen and the number of dots of one line so as to match the resolution of the display data output by the CPU with the liquid crystal display.

Abstract: An information processing system having a character/pattern generator, in which outline information of a character/pattern expressed in a vector form is subjected to any of at least two sorts of coordinate transformations in accordance with an address allocation scheme of an output engine to-be-used. Besides, in generating and transferring character/pattern data of dot form for each of the outline information items of character/pattern parts in subregions into which a region of the character/pattern has been divided, the outline information of the character/pattern is divided in either of horizontal and vertical directions in data transfer unit in accordance with the address allocation scheme of the output engine to-be-used. Further, in transferring the character/pattern data of the dot form, addresses are updated in conformity with any of at least two address update schemes in accordance with the address allocation scheme of the output engine to-be-used.
