Title: Defect detection method
Inventor: NAKAMOTO SHIGEMI
IPC: B21C51/00
Filed: 2002-10-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a defect detection method for performing detection and classification on injurious defects by using an effective feature quantity with respect to local frequency of a luminance signal and directionality of the spread of a defect.  <P>SOLUTION: This defect detection method for detecting a defect developed on a surface of an industrial product by an optical method is characterized by dissolving an image signal acquired by imaging into multiple resolution components by two-dimensional wavelet transform, previously selecting multiple resolution components corresponding to the characteristics of the defect to restore images by two-dimensional inverse wavelet transform, and selectively extracting images of defective and non-defective elements each having an intrinsic local frequency and an intrinsic shape. Edges of a steel sheet can be detected by binarizing the restored images and extracting linear factors by means of Hough transform. Different combinations of the resolution components and the number of remaining pixels of the binarized images can be used. Further, defects can be classified by applying a maximum likelihood determination method to the number of remaining pixels.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-10-28
Abstract: <P>PROBLEM TO BE SOLVED: To precisely calculate a lag time of a cell under an objective electric power source voltage, even when a lag time table in which the electric power source voltage is only one kind is prepared.  <P>SOLUTION: An approximate function for expressing the lag time of the representative cell as a function of the electric power source voltage is prepared in an approximate function preparing process F1. A transition time S of an input signal waveform and the lag time of a load capacity C are found by interpolation, based on the lag time table 150 of the electric power source voltage V1 of the one kind in the every cell, in a lag time calculating process F42. Then, an interpolation function g (Vdd) corresponding to the lag time found by the interpolation is calculated in an interpolation function calculating process F22. Substitution is conducted with a supplied electric power-source voltage Vdd in the calculated interpolation function g (Vdd) in a lag time interpolation process F32 to calculate the lag time of the transition time S of the input signal waveform and the lag time of the load capacity C.  <P>COPYRIGHT: (C)2003,JPO

Filed: 2002-11-08
Abstract: <P>PROBLEM TO BE SOLVED: To stabilize operation, to increase operation speed, and to reduce power consumption, with low power source voltage.  <P>SOLUTION: Threshold voltage of a transistor used for a memory cell Qs is made higher than threshold voltage of a transistor used for a word driver WK, and threshold voltage of a transistor used for the word driver WD is made higher than threshold voltage of a transistor used for a voltage converting circuit VCHG for word line. The voltage converting circuit for driving word line is provided with MISFETQE having a gate connected to a drain of a charge pump circuit. Further, cross couple is formed in the charge pump circuit. Therefore, a leak of electronic charges of a memory cell is prevented and a refresh- characteristic is stabilized. When the number of word drivers are many and threshold voltage is low, a leak current is problem as total sum, such a leak current is prevented effectively. Also, as a circuit scale of the voltage converting circuit is not so large, a leak current is relatively small as total sum, as MOS of threshold voltage can be utilized, driving capability is improved and stabilized even with low power source voltage.  <P>COPYRIGHT: (C)2003,JPO
