Abstract: An information generation method includes: receiving dictionary data used for morpheme analysis; and generating index information indicating relative positions of characters of each character included in a word registered in the dictionary data, a character at a head of the word, and a character at an end of the word based on the received dictionary data, by a processor.

Abstract: A learning method includes receiving first text information and second text information, acquiring first word information that identifies a combination of one of words included in the first text information and a word meaning of the one of the words, acquiring second word information that identifies a combination of one of words included in the second text information and a word meaning of the one of the words, specifying, by referring to a storage in which word meaning vectors associated with corresponding word meanings of words are stored in association with word information that identifies combinations of the words and the word meanings of the words, a first word meaning vector associated with the first word information and a second word meaning vector associated with the second word information, and learning parameters of a conversion model, by a processor.

Abstract: The present invention provides a method for producing a carbon nanotube having a high purity and a method for purifying an unpurified carbon nanotube or a carbon nanotube having a low purity. The method for producing a carbon nanotube comprises a step of providing a carbonaceous material containing a carbon nanotube and a step of adding an iron material and hydrogen peroxide to the carbonaceous material to thereby purity a carbon nanotube. It is preferred that an iron powder is used as the iron material. The iron powder is preferably used in a proportion of 0.5 to 20 parts by mass relative to 100 parts by mass of the whole carbonaceous material.

Abstract: Screen display matched to the progress of execution of the initialization function in small and inexpensive devices such as a portable terminal is performed. Furthermore, reliability in the event of an error is improved without providing excessive redundancy and with limited capacity in a NAND flash memory storing programs. A first boot layer and a second boot layer of the same content are stored in the NAND flash memory. The boot layer free from errors is copied (C2) to a RAM (step S21), and a boot layer program is executed in the RAM (step S30). A simple logo and the like comprising characters is then displayed (first screen display) (step S32). Next, a system layer program is executed in the RAM (step S40). A screen (second screen display) is then displayed by switching between a plurality of images (step S44).

Abstract: A method and apparatus for sorting object data, the object data having a data format of a next address and a record. The next address indicates the address of another object data, and the record includes information data which is the subject of the sort. The sorting method and apparatus perform two sorting processes. The first process performs a divisional sort which sorts the object data into blocks of object data; these blocks being sorted with respect to one another. In sorting the object data into these object data blocks, it is unnecessary to actually move the object data within the memory. Instead, only one address of an object data out of all the object data in a block needs to be stored. Use is made of the next address of the object data to link the remaining object data to the single object data stored in an object data block. Then the second sorting process performs a sort of the object data in each block; thus all the object data becomes sorted.

Abstract: A golf ball having a large carry having a core, a rubber thread layer and a cover layer, in which the rubber thread is composed of a rubber composition consisting essentially of 100 parts by weight of natural rubber and/or cis-1,4-polyisoprene and 2-20 parts by weight of carbon black.

Abstract: A process for preparing ultrafine carbide powder of silicon or titanium and other carbide which are used as refractory materials comprises the steps of passing electric current to a carbon member held in contact with a material such as silicon in a vacuum vessel into which an inert gas at a desired pressure is introduced and collecting a carbide powder of the material fuming into the gas as a result of a high-temperature reaction between the material and carbon member in contact, thus producing carbide powder of ultrafine particles and of high-purity with high efficiency. A preheater facilitates the passing of electricity through the material by reducing the resistance thereof and leads to efficient preparation of the ultrafine carbide powder.
