A method of recognizing a character specifies a character in an image. Furthermore, the method of recognizing a character evaluates a symmetrical-ness of a shape of the character. Furthermore, the method of recognizing a character carries out an inclination correction process for the shape when the symmetricalness of the shape is detected.

Method of recognizing character in which correction of inclination of character is carried out and apparatus for carrying out this method

A character segmentation system for segmentation out a character from a string of characters which are in touch with each other, which is capable of being executed on a small size hardware resource without influence of variation of touching condition due to difference of character font, comprises an image storing unit,for storing an electronic image of character string obtained by such means as optical scanning, a partial pattern dictionary,for storing partial pattern shapes used as features for specifying fonts of character, a partial pattern detecting unit,for extracting areas of the image of character string, which coincide with a partial pattern, a character font determining unit,for determining the font of character on the basis of positions of the areas of the image of character string, which coincide with the partial pattern, and the number of the areas, a feature extraction inhibited area dictionary,for storing areas in which feature extraction processing for respective fonts of character is inhibited, a character separating feature extracting area defining unit,for defining areas of the image of character string, from which character separating features are to be extracted, by referring to the feature extraction inhibited area corresponding to the font of character determined by the character font determining unit, a character separating feature extracting unit,for extracting the character separating feature from the areas for extracting the character separating feature, a character boundary position detecting unit,for detecting positions at which characters are to be separated from each other and a control unit,for controlling operations of all of the constructive components.

An electroplating bath solution for zinc-cobalt-iron alloy and electroplated product electroplating by the bath solution are described. The electroplating bath solution containing 5-30 g/l Zn, 0.01-0.3 g/l Co and 0.02-0.5 g/l Fe, and electroplating layer of the product contains 0.1-0.6 wt % Co, 0.2-0.7 wt % Fe and Zn. The electroplated product gives a high quality black chromate film at cheaper cost than before.

Electroplating bath solution for zinc alloy and electroplated product

An aqueous acidic electrolyte of the chloride, sulfate and mixed chloride-sulfate types suitable for electrodepositing a zinc-nickel alloy on a conductive substrate comprising an aqueous solution containing zinc ions and nickel ions, and an additive agent of a class selected from the group consisting of (a) aromatic sulfonic acids, (b) aromatic sulfonamides, sulfonimides and mixed carboxamides/sulfonamides, (c) acetylene alcohols as well as the bath soluble and compatible salts and mixtures thereof. The invention further encompasses the process for electrodepositing a zinc-nickel alloy employing the aforementioned electrolyte.

Zinc-nickel alloy electrolyte and process

The present invention includes an aqueous acidic chromate solution, suitable for forming colored chromate coatings on zinc-nickel alloy electrodeposits containing up to about 15% by weight nickel, which solutions have a pH within the range of about 1.3 to about 2.7, a hexavalent chromium concentration of at least 0.5 grams per liter, and preferably about 0.5 to about 100 grams per liter, and which contain sulfate in a weight ratio of SO.sub.4 :Cr.sup.+6 of about 0.025-1.5:1. The zinc-nickel alloy electrodeposits are preferably immersed in the chromating solution for a period sufficient to form the desired colored chromate coating. In some instances, a flash electrodeposit of zinc may be applied to the zinc-nickel alloy electrodeposit before it is immersed in the chromating solution. Alternatively, the zinc-nickel alloy electrodeposit may be immersed in the chromating solution and the solution electrolyzed, with the zinc-nickel alloy surface as the anode, at low current densities for a short period of time, after which, the electrolysis is discontinued and the zinc-nickel alloy surface is maintained in the chromating solution until the desired colored chromate film is formed.
