Abstract: PURPOSE:To improve the linearity of an A/D converter by performing the subtraction of random number either before or behind the A/D converter and adding the same random number on the other side, and making a correction based upon a correction value found by using the output of the A/D converter. CONSTITUTION:Subtracters 31 and 32 subtract the random numbers DELTARX and DELTARY from analog position signals X and Y and the differences are A/D-converted by A/D converters 21 and 22 and sent to a correction calculating circuit 15 to access and read the correction value for linearity correction etc., digital values (X-DELTARX) and (Y-DELTARY); and adders 61 and 62 add the correction value to the output of the A/D converter and send the sums to the adders 71 and 72 to add the same random number DELTARX and DELTARY. The random numbers DELTARX and DELTARY are canceled eventually and even when the A/D converters 21 and 22 have the nonlinearity, the inputs are dispersed at random and averaged to prevent the output data from losing smoothness, so that such problem that a stripe appears in a picture is eliminated.

Title: Electronic circuit using comparator
Inventor: SHIBATA FUMIO
IPC: H03K7/02
Filed: 1989-07-03
Abstract: PURPOSE:To compensate the temperature characteristic of a comparator section at the comparator section itself by adding an output saturation voltage of a 2nd comparator having the equal temperature characteristic to a signal voltage to be modulated by the comparator. CONSTITUTION:A voltage Vp being the sum of a signal voltage Vs resulting from a voltage across a resistor R caused by a signal current I1 flowing thereto and an output saturation voltage of a comparator 3 is inputted to a noninverting input terminal of an operational amplifier 1. Thus, suppose that the output saturation voltage of the comparators 2, 3 is identical by taking the temperature characteristic into account, then the peak value of the modulation signal is equal to a signal voltage Vs regardless of the temperature. Thus, when the resistance of a resistor Rc is set so that load currents I2, I3 of the comparators 2, 3 are nearly equal to each other, the output saturated voltage and its temperature characteristic of the comparators 2, 3 in one and same package are nearly equal to each other and the temperature characteristic of the output saturation voltage of the comparator 2 is compensated.

In this instance, the (3X3) matrices A11-A33 which are previously stored are defined as one set. Then plural sets of chroma saturation correction coefficients are selected based on the preceding luminance ratio, and R' G' B' is calculated from the arithmetic result of each expression and converted. Thus it is possible to reduce the variance of chroma saturation caused by the range of density of the color images and to automatically reproduce the satisfactory colors according to each pattern.

Title: Via-filling method
Inventor: HONMA HIDEO
IPC: H05K3/46
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To enable via filling to be formed efficiently through a simple operation by a method, wherein a non-electrolytic metallic film is formed into a via hole, and then metal electroplating is carried out through PR electrolysis. SOLUTION: Since metal concentration and current distribution are not uniform in a via hole which is small and deep, generally a current is lessened in density or agitation is intensified, so as to form an electroplating film uniform and superior in electrodeposition properties in the via hole. Metal, preferentially separated out at an opening, dissolved by inverting electrodes in polarity through a PR electrolysis, so that electroplating is carried out in such a state that excess metal ions are produced in concentration near a separating point in a via hole at all times, and a uniform film can be formed for the formation of a via-filling without regulating a current density or agitation. In this manner, a via filling is formed through a comparative simple means such as an electroplating method, so that via-filling method is very effective for the manufacture of various circuits.
