Title: Method and device for normalizing hand-written character, and recording medium recorded with program therefor
Inventor: NAGAISHI MICHIHIRO
IPC: G06K9/36
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To efficiently execute detecting and correcting processings by presuming the shape of a circumscribed rectangle which expresses the rotation and shearing deformation of a character from the stroke angles of the character in vertical and horizontal directions and attain detection from the inflection point part of a projection function based on relation between the respective angles with a projection and the number of integration pixels. SOLUTION: The shape of the circumscribed rectangle is guessed by the angles of the character in vertical and horizontal strokes. In this case, when the projection direction coincides with the vertical stroke direction of the character, the projection becomes sharp. When the projection direction comes out of the vertical stroke direction, the projection becomes the flat one and a sharpness is reduced. When the projection is used, the width of the projection in a state where the character is erect without the rotation and shearing deformation is narrowed so that a rotary angle is presumed by the change of the width of the projection.  Then, a detecting algorithm by the entropy of the projection by which the sharpness of the picture is uniquely evaluated is utilized as the projection function based on relation between the respective angles with the projection and the integrated values of the pixels.

Title: Circuit for stabilizing high voltage generated in ic chip
Inventor: NISHIOKA HIROSHI
IPC: H01L29/866
Filed: 1987-06-30
Abstract: PURPOSE:To stabilize a high voltage generated at the output of a charge pump circuit at the time of boosting mode by connecting an N<-> well Zener diode to the output of a low voltage/high voltage switching circuit. CONSTITUTION:A Zener diode is formed in an N<-> well NW formed on a P<-> type substrate PS, and a pattern of an N<+> type diffused region NR is formed in the pattern of a P<+> type diffused region PR. 3 stages of Zener diodes (ZD1, ZD2, ZD3) are connected in series with a GND to the output of a low voltage/ high voltage switching circuit KC. Since a P<+> type thermal diffusion coefficient is larger than an N<+> type thermal diffusion coefficient, it is difficult to so set both N<+> and P<+> type high concentrations highly in the N<-> well. Accordingly, a Zener voltage of 10V or higher is scarcely obtained. Even in this embodiment, 3 stage Zener diodes are composed in a section for stabilizing a high voltage. This circuit system can stabilize the high voltage at the time of boosting mode to the three times (3 .Vz) of the Zener voltage (Vz).
