Title: Recognizing system of handwritten character
Inventor: ICHINOTO YASUO
IPC: G06K9/62
Filed: 1983-09-12
Abstract: PURPOSE:To recognize a handwritten character by selecting a segment having a lower degree of difference among the segments of the other (one) side for either one of an input and a standard pattern as the 1st (2nd) segment correspondence group and obtaining the degree of the difference among the groups which share 1 or more segments within both groups. CONSTITUTION:A standard pattern S approximated by a broken line and an input pattern S' are normalized according to the size and positions of centroids and superposed to obtain the degree of the difference of the segments between both patterns. The segment having the lower degree of the difference is obtained, and plural groups are formed in paired forms, i.e., the 1st group l1:l1' and the 2nd group l2, l3:l2', l3', l4' respectively. Then l4:l5', l6' is finally ob tained. The degree of difference is detected for each group. Then the sum total of these degrees of difference is defined as the degree of difference between both patterns. This method is applied also to other standard patterns to decide an input pattern approximating a standard pattern. Thus the characters are recognized.

Title: Production of aminobenzylamine
Inventor: YAMAGUCHI KEISABUROU
IPC: C07C211/53
Filed: 1983-09-12
Abstract: PURPOSE:To produce the titled compound useful as a raw material of an epoxy resin hardener, etc. in high yield, by the catalytic reduction of nitrobenzaldoxime in the presence of boric acid, phosphoric acid and/or their anhydride. CONSTITUTION:Aminobenzylamine is produced by the catalytic reduction of the nitrobenzaldoxime of formula (the configuration of nitro group is m- or p-) in the presence of boric acid, phosphoric acid and/or their anhydride. The reduction is carried out in an organic solvent in the presence of >=2 equivalent of boric acid, phosphoric acid and/or their anhydride. Various intermediates produced by the reduction, e.g. amines, imines, etc. are stabilized in the form of borates or phosphates. The basicity of the amino group and the imino group of the salt is lowered by the stabilization, which causes the suppression of the decomposition and side reactions, the acceleration of the reduction of the nitro group and the aldoxime group, and the production of the objective compound in high selectivity. The activity of the catalyst does not decrease by the reaction and the catalyst can be reused for the reaction.

Abstract: PURPOSE:To perform constantly the appropriate line pressure control during the changing of the speed, by changing a set point of an inertia phase time corresponding to a shift pattern used in the changing of the speed, that is, corresponding to the speed at the time of changing of the speed. CONSTITUTION:In a change gear mechanism, a line pressure selectively actuates each kind of friction element so as to perform the predetermined changing of the speed. During this time, an inertia phase time measuring means measure a time when a gear ratio has been changed, that is, the inertia phase time, on the basis of a signal from the input and the output rotation sensors, and a line pressure adjusting means controls the line pressure so that the measured time coincides with the set point. In this case, a shift pattern signal output means outputs a signal showing the kind of shift pattern as a base of the chang ing od the speed of an automatic transmission, and a set point changing means changes the set point of the inertia phase time in the line pressure adjusting means on the basis of the signal, that is, corresponding to the speed at the time of changing of the speed. The line pressure during the changing of the speed can be thus controlled appropriately.
