  • Patent number: 6496191
    Abstract: A character font generation apparatus generates a font of a character for the output of the character to an output unit. First, whether the character specified through the operation of an input unit can be output in a desired font based on a predetermined resolution of the output unit or not is determined. If the result of the determination is no, a stroke of the character is omitted to reduce the size of the character, to allow the correct output according to the predetermined resolution. The stroke omission is performed with reference to contents of a memory storing various information necessary for the character font generation and a priority determination rule indicating various information for determining the priority of stroke omission, so as to maintain the balance and to preserve the shape (contour) of the character.

  • Publication number: 20020070938
    Abstract: A character font generation apparatus generates a font of a character for the output of the character to an output unit. First, whether the character specified through the operation of an input unit can be output in a desired font based on a predetermined resolution of the output unit or not is determined. If the result of determination indicates “output not allowed”, a stroke of the character is omitted to reduce the size of the character to allow the correct output according to the predetermined resolution. The stroke omission is performed with reference to contents of a DB (database) memory storing various information necessary for the character font generation and a priority determination rule indicating various information for determining the priority of stroke omission, so as to maintain the balance of the character such as center and centroid thereof and to preserve the shape (contour) of the character.

  • Patent number: 5541838
    Abstract: A translation machine is provided with an idiom registering capability. If a header standing for a idiom contains two or more variable parts, these parts are represented by representative symbols. With this representing method, the idiom is allowed to be easily registered and retrieved. This makes it possible to shorten the registering time, reduce the translating toil and prevent increase of information storage capacity. The translation machine includes an input unit, a storing unit, an output unit, an idiom registering unit, and a translating unit for performing a routine translating operation. The idiom registering unit operates to register an idiom header with two or more representative symbols standing for words or word trains sharing a predetermined attribute.

  • Patent number: 5279856
    Abstract: A hydrophilic porous membrane is obtained by covering porous membrane substrate with a non-ionic, amino-acid-based or non-ionic fluorine-based surface active agent. For the covering, the porous membrane substrate is immersed in a solution containing the surface active agent and then drying the membrane substrate. A different hydrophilic porous membrane is obtained by providing the surfaces of a porous membrane substrate and inner pore surfaces with a polar group and then covering the membrane substrate with a hydrophilic polymer film. For this covering, after introduction of the polar group to the surfaces of the porous membrane substrate and inner pore surfaces, the membrane substrate is immersed in a solution containing a hydrophilic substance and then dried.
