  • Patent number: 12248758
    Abstract: A generation device is a device that generates a translated sentence in a second language from an input sentence in a first language to be translated. The generation device includes: an acquisition unit that acquires the input sentence; a normalization unit that converts the input sentence into a normalized sentence that is a grammatically correct sentence in the first language; and a first translation unit that generates the translated sentence by translating the normalized sentence into the second language using first parallel translation data that is parallel translation data between the first language and the second language. The normalization unit generates the normalized sentence by using second parallel translation data that is parallel translation data between a third language and the first language. A data amount of the second parallel translation data is larger than a data amount of the first parallel translation data.

  • Patent number: 10481552
    Abstract: An image forming apparatus that forms a toner image on a recording medium includes an image forming unit that forms an unfixed toner image on a recording medium; a fixing unit that heats the recording medium bearing the unfixed toner image and fixes the unfixed toner image onto the recording medium at a nip portion; a heating member and a pressurizing member that touches the heating member and forms the nip portion therebetween; a first blower that blows air to a non-sheet-passing area of a small-size recording medium in the heating member; and a second blower that blows air to a non-sheet-passing area of a small-size recording medium in the pressurizing member. Upon the temperature of the non-sheet-passing area of the heating member exceeding a threshold temperature, the first blower blows without the second blower blowing, then the two blowers start blowing together.
