Abstract: A method for detecting a leakage position in an impervious sheet, which comprises disposing a first and a second electrode units on an upper side and a lower side of the impervious sheet, respectively, the first electrode unit intersecting with the second electrode unit; short-circuiting all of electrodes in the first electrode unit; selecting a plurality of electrode sets one set after another set in the second electrode unit, each set comprising three electrodes adjacent to each other; supplying an AC voltage from an AC power source across a central one of each electrode set and the short circuited electrodes of the first electrode unit; measuring a potential difference between the other electrodes in the each electrode set to produce a measured voltage signal; and phase-detecting the measured voltage signal with a signal synchronized with the AC voltage from the AC power source to produce a detected signal, a series of the detected signals produced one after another changing in polarity due to a damage existing in the sheet, whereby a first position of the damage being detected on a one dimensional coordinate in an extending direction of the first electrode unit. Thereafter, the similar operation is carried out by replacing the first and the second electrode units by each other to obtain a second position of the damage on a one-dimensional coordinate in an extending direction of the second electrode unit; and defining a two-dimensional position of the damage from the first and the second positions.

Abstract: In an image forming apparatus for forming an ordinary copy or a tonality image for an original image for a printing press, original image data is divided into data within a predetermined area and that outside the area, and pixel density within the area is subjected to a density conversion in accordance with screen half-toning information which will increase density information toward the approximate center of these pixels, by way of example. The original image data or the density-converted image data is converted into a binary-coded signal conforming to the density, and an output image is formed in accordance therewith. Preferably, plural types of non-linear correction tables are provided and a tone-conversion is performed selecting an appropriate correction table for each pixel, or for each line, of the density-converted image data. Preferably, the original image data is binary coded by a pattern signal having a long period, and the density-converted image data is binary coded by a pattern signal having a short period. The foregoing is applied to color-separated image data of each color. Preferably, the image data is divided, in accordance with color, into predetermined areas having the same or a different number of pixels, or into predetermined areas having a planar phase which differs for each color, and a screen angle is applied thereto.

Abstract: An image processing apparatus includes a D/A converter for generating an analog image signal, a variable resistor for changing an output range of the analog image signal generated by the D/A converter, and a comparator for processing the analog image signal generated by the variable resistor by using an analog pattern signal and for outputting a pulse width modulated signal. The analog pattern signal may be a triangular wave signal, a saw-tooth wave signal, a sine wave signal, or a trapezoidal wave signal. In another version, selection is performed between predetermined data and a generated image signal and the selected signal is processed using an analog pattern signal (e.g., a triangle wave) to output a pulse width modulated signal. A D/A converter may be used to convert the output of the selection. The output range of the DAC may be variable.

Abstract: A remote file server managing a remote storage device and a local file server managing a local storage device are coupled to a communication network (e.g. the Internet). The local file server (A) replicates a file in the local storage device to the remote file server and, (B) if a first condition is satisfied, manages the replicated file which is the file from which the data is replicated as a migration target file. The local file server, even if the (B) is completed, does not delete the migration target file from the local storage device and, if the second condition is satisfied, deletes the migration target file from the local storage device.
