    Abstract: A method for producing a high-quality group-III element nitride crystal at a high crystal growth rate, and a group-III element nitride crystal are provided. The method includes the steps of placing a group-III element, an alkali metal, and a seed crystal of group-III element nitride in a crystal growth vessel, pressurizing and heating the crystal growth vessel in an atmosphere of nitrogen-containing gas, and causing the group-III element and nitrogen to react with each other in a melt of the group-III element, the alkali metal and the nitrogen so that a group-III element nitride crystal is grown using the seed crystal as a nucleus. A hydrocarbon having a boiling point higher than the melting point of the alkali metal is added before the pressurization and heating of the crystal growth vessel.

  • Patent number: 8099427
    Abstract: A search article estimation apparatus is provided that is capable of estimating an article that a user is trying to search for, even when the user cannot accurately provide information on the article that the user wants to search for. The state of access to a storage equipment by the user and a change in articles in the storage equipment during the access are checked by a sensing apparatus. If there is no change in articles, then a search state detection means determines that the user has performed an article search but has been unable to find the article. Furthermore, a search article estimation means refers to a storage location database and estimates an article that should originally be stored in the storage equipment, to be the article that the user is searching for.

  • Patent number: 8005379
    Abstract: An image forming apparatus is provided with a control section which stores detection results of a toner sensor regarding detection patterns. When forming a plurality of detection patterns on an intermediate transfer belt, the control section determines circumference-directional lengths of the detection patterns formed this time, based on the detection results of the toner sensor regarding the detection patterns formed immediately before. Thereby, the waste toner amount and toner consumption are not only decreased but also the time taken to detect the density of a detection pattern is reduced, while maintaining the detecting accuracy thereof.
