Title: Method for processing two-dimensional data
Inventor: USUI NOBUAKI
IPC: G06F17/10
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To perform data processing such as differentiation without making deterioration of data by sequentially extracting a one-dimensional data stream from two-dimensional processing data and calculating an approximation expression by approximating the one-dimensional data stream with a polynomial that uses a Chebyshev function. SOLUTION: Two-dimensional image data D(I, J) consists of pixel position data z in the directions X and Y of each pixel and pixel data y(z) which shows gradation. Dot column image data D(J) of a J-th column are extracted among the data D(I, J) after resetting a variable J that shows the position of a pixel column to be extracted there. An approximate expression is calculated by approximating the extracted one-dimensional data stream D(J) with a polynomial that uses a Chebyshev function. A differential expression of the approximate expression is calculated by differentiating the approximate expression and the differential value of processing data is acquired by calculating the differential value of each data of the data stream D(J) by using the differential expression.  In such cases, because an approximate expression that uses the Chebyshev function is an aperiodic function, it approximates even to processing data in which values arbitrarily fluctuate with high accuracy.

Title: Power converter
Inventor: YAMAMOTO SHIROJI
IPC: H02M1/32
Filed: 1993-06-03
Abstract: PURPOSE:To enable detection of abnormality using minimum number of components by gating a control rectifying element OFF and firing a semiconductor for suppressing overvoltage when the difference of current flowing through the resistors in two snubber circuits exceeds a predetermined level. CONSTITUTION:The power converter employs an instrument current transformer(CT) having two primary windings connected, respectively, with resistors 51, 52. A load resistor 8 is connected with the secondary winding of the CT7 and when the voltage across the resistor 8 exceeds a predetermined level, a detection signal is delivered from a detection circuit 9. When a GTO thyristor 12 breaks down due to abnormality and conducted, a current having double peak value flows through a resistor 51 of a snubber circuit 21. Current having high amplitude flows thereby through the primary winding, as a whole, to induce a voltage corresponding to the current waveform across the load resistor 8. Consequently, breakdown of any one snubber circuit is detected and the operation of sound GTO thyristor is interrupted. At the same time, a semiconductor element for suppressing overvoltage is fired.
