Abstract: A high-strength cold-rolled steel sheet has a chemical composition containing C: 0.150 to 0.350 mass %, Si: 0.80 to 3.00 mass %, Mn: 1.50 to 3.50 mass %, P: 0.100 mass % or less, S: 0.0200 mass % or less, Al: 0.100 mass % or less, N: 0.0100 mass % or less, and O: 0.0100 mass % or less, with a remaining part consisting of Fe and impurities. The amount of diffusible hydrogen is 0.50 mass ppm or less, the area ratio of tempered martensite and bainite is 55 to 95%, the area ratio of retained austenite is 5 to 30%, a prior austenite grain has an average circle equivalent diameter of 15.0 ?m or less, and the ratio b/a is 0.80 or less, where a circumferential length of the prior austenite grain is a, and a circumferential length of a portion of the prior austenite grain having a carbon concentration of 0.6 mass % or more is b.

Abstract: An information processing apparatus includes a display, an input unit, and a controller. The input unit is configured to receive an input of a first keyword from a user. The controller is configured to retrieve first character information including the input first keyword from a database configured to store a plurality of character information items converted from a plurality of voice information items by voice recognition processing, extract a second keyword that is included in the first character information acquired by the retrieval and is different from the first keyword, and control the display to display a list of items including first identification information with which the acquired first character information is identified and the second keyword included in the first character information.

Abstract: There is provided a playback device including a content playback unit configured to playback content, a playlist acquisition unit configured to acquire, while the playback unit is playing back the content on the basis of a playlist, at least one external playlist from outside, the external playlist having at least two pieces of content that are common to content in the playlist and having a matching playback order of at least the two consecutive pieces of content, and a playlist display unit configured to display the playlist and the external playlist acquired by the playlist acquisition unit such that the playlists are linked at positions of the consecutive matching pieces of content.
