Filed: 1989-12-05
Abstract: PURPOSE:To reduce power consumption of a whole device by providing a low power consumption type-clock buffer, and supplying a clock signal to a digital circuit. CONSTITUTION:In the clock signal outputted from output terminals A11 and B12 of a clock generation means 10, it is set that the 'H' period of the signal from the terminal A11 is longer than the 'H' period of the signal from the terminal B12 and the 'L' period of the signal from the terminal B12 is longer than the 'L' period of the signal from the terminal A11.

IPC: G06K9/68
Filed: 1990-11-21
Abstract: PURPOSE:To eliminate wrong recognition caused by the difference of a character type by inspecting whether the feature of an inputted character has feature information for each character type stored in a recognition dictionary or not. CONSTITUTION:A character input means 5 calculates the feature information of the character for each character from picture information read by a scanner 13 and outputs it to a character type discriminating means 6 and a character type converting means. The character type discriminating means 6 discriminates it from the feature information of the character whether the inputted character is a Ming typeface of a Gothic typeface, and outputs the result to a dictionary selecting means 8. Further, a character recognizing means 9 compares the feature information of the character with information stored in the recognition dictionary and outputs the character showing the most coincident information on a display 15 as the recognizing character corresponding to the inputted character. Thus, there is no wrong recognition caused by the difference of the character type between the feature information of the inputted character and the information stored in the recognition dictionary.

Title: Manufacture of grain oriented silicon steel having stress relief annealing resistance and low core loss
Inventor: MOGI TAKASHI
IPC: C21D8/12
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To show the optimum instruction of manufacture according to application magnetic flux density and to manufacture a steel sheet from deterioration in core loss due to stress relief annealing by regulating B8 deterioration before and after the formation of grooves in a steel sheet to a specific value when the design magnetic flux density of a transformer for which the steel sheet is used is set at a specific value. SOLUTION: Core loss is improved by physically forming grooves in a finish annealed steel sheet to fractionize a magnetic domain. When the design magnetic flux density of a transformer is >=1.7 T, B8 deterioration before and after the formation of the grooves in the steel is 0.03-0.06 T. It is preferable that B8 deterioration becomes 0.04-0.06 T when the design magnetic flux density of the transformer is 1.4-<1.7 T and that B8 deterioration becomes 0.04-0.06 T when the design magnetic flux density becomes <1.4 T. A fixed relationship is held between the amount of B8 deterioration and core loss after the magnetic domain fractionization, and the depth of the grooves is regulated as a means of regulating B8 deterioration.  Core loss characteristic after stress relief annealing treatment is regulated so that most suitable core loss can be obtained according to the applied magnetic flux density, and the energy loss of the transformer can be reduced.
