Title: Character recognizer
Inventor: TAKENOUCHI MARIKO
IPC: G06K9/62
Filed: 1984-07-20
Abstract: PURPOSE:To obtain a highly accurate and stable character recognition by extracting projections in each side direction of a subject character pattern concerned, which is rectangularly segmented and utilizing the number of projections and their shapes as features for character recognition. CONSTITUTION:A subject character to be recognized is binarized into black and white from a picture signal in a picture input part 9 so as to be inputted, while a character segmenting part 10 segments a rectangular pattern from the input picture as a recognized subject character pattern. A histogram calculating part 11 calculates histograms of distances from a character part to each top right- hand side and bottom left-hand side, and obtains four histograms for expressing the irregularity of the recognized subject character pattern with respect to sides in four directions. A projection extracting part 12 detects maximum points of four histograms and obtains projection information on the number of projections corresponding to each side direction and positions. A projection shape extracting part 13 extracts the shape of the projection from four histogram and projection information. A recognizing part 16 collates features extracted by a feature extracting part 14 with a dictionary 15, obtains a recognition candidate character and displays the recognized result on a display part 17.

Filed: 1983-08-22
Abstract: PURPOSE:To ensure a safe reignition of burner with no risk of explosion, by providing a means adapted to interrupt the reignition of burner for a specific time duration after a miss ignition of burner. CONSTITUTION:By opening a hot water feed cock 9, a water flow switch 9 is turned ON and a condenser C increases its voltage higher than a reference voltage. A comparator 12 outputs an operation signal to a combustion actuation circuit 11 to effectuate an ignition trial a1.

An electrical discharge is thus effectuated via a second discharge circuit 14, so that the voltage condenser C may be reduced to zero. Hence, the ignition trial a1 is not actuated until the voltage of condenser C is increased to a reference voltage, even when a water flow switch 9 is turned ON in an attempt to reignite. In turn, a pre-purge a2 is actuated by natural ventilation.
