Title: Character reader
Inventor: SUDA MASATO
IPC: G06K9/34
Filed: 1992-04-23
Abstract: PURPOSE:To provide a character reader where a character is normally and stably detected and segmented for a character picture generated by dots. CONSTITUTION:A photoelectric converting part 1 converts the character picture generated by the dots into an electric signal by optical scanning. An A/D converting part 2 converts the output signal of the photoelectric converting part 1 into a digital signal and stores it in the multi-picture memory 3 as the multi-character picture. A max. density value pick-up part 4 repeatedly scans the character picture which is stored in the multi-picture memory 3 so that max. density value data on respective scanning lines is picked-up. A row detecting and segmenting part 5 detects and segments a character row from the picked-up max. density value data. A character detecting and segmenting part 6 obtains the detecting and segmenting position of the character from the continuity of width between the maximal values of max. density value data on the respective scanning lines in the scanning direction of the character picture and detects and segments respective character units from the detected and segmented character row. A character recognizing part 7 recognizes the respective detected and segmented characters.

IPC: B01D46/42
Filed: 1981-07-07
Abstract: PURPOSE:To improve durability and safety and simplify structure, by making up a collecting material with a ceramic form of three-dimensional reticulate structure and installing a wall which sections an exhaust gas passage of the collecting material into plural lines. CONSTITUTION:A collecting material 28 is made up of a ceramic form while a wall sectioning an exhaust gas passage of a collecting material 28 into plural lines is installed and furthermore plural electric heater elements 26 are dispersedly arranged each at the upstream end of the collecting material 28 in order to meet each passage of the material 28. With this, the collecting material 28 gets strengthened itself and, what is more, combustion of the exhuast corpuscle is not diffused around wastefully, shortening the regenerating time as combustion is transmitted still earlier in the axial direction. In addition, since a drift of exhaust gas is obviated by dint of the wall 29, there is no fear of producing a portion of incomplete combustion at all.
