Abstract: A method of manufacturing a plurality of chips by dividing a workpiece having a substrate harder than a monocrystalline Si substrate includes a cut groove forming step of, while holding the workpiece on a holding table with a surface of the workpiece being exposed, cutting the workpiece along each of projected dicing lines with a first cutting blade as it is vibrating at a frequency in the ultrasonic band, to form a cut groove in the workpiece such that the cut groove extends from the surface of the workpiece and terminates short of another surface of the workpiece, and a dividing step of, while holding the workpiece on the holding table with the other surface of the workpiece being exposed, cutting off an uncut residual portion from the workpiece along each of the lines with a second cutting blade to divide the workpiece into a plurality of chips.

Abstract: An information processing device is configured to identify language of character strings in a text. The information processing device includes a processor and a memory storing a program. The processor is configured to or the program, when executed by the processor, causes the processor to: identify a first character, which is used commonly in a plurality of languages, in an input text; infer to which one of the plurality of languages the first character belongs based on a second character used only in one of the plurality of languages in the input text; and infer that the first character belongs to a language that is the one of the plurality of languages to which the second character belongs, based on whether a string of characters immediately preceding or following the first character in the input text contains the second character.

Abstract: The information processing device includes: an acquisition unit configured to acquire a first character used commonly in a plurality of languages; and an inferring unit configured to infer to which one of the plurality of languages the first character belongs based on a second character used only in one of the plurality of languages. If a string of characters immediately preceding or following the first character contains the second character, the inferring circuitry infers that the first character belongs to a language that is the one of the plurality of languages to which the second character belongs.
