Abstract: Disclosed is a non-heat-treated steel that has low deformation resistance during cold forging in bolt head forming and excellent product yield, and that can be manufactured without the need to perform heat treatment for controlling strength variation. The disclosed steel has a chemical composition containing C: 0.18-0.24%, Si: 0.10-0.22%, Mn: 0.60-1.00%, Al: 0.010-0.050%, Cr: 0.65-0.95%, Ti: 0.010-0.050%, B: 0.0015-0.0050%, N: 0.0050-0.0100%, P: 0.025% or less inclusive of 0, S: 0.025% or less inclusive of 0, Cu: 0.20% or less inclusive of 0, and Ni: 0.30% or less inclusive of 0, in a range satisfying: 0.45?C+Si/24+Mn/6+Ni/40+Cr/5?0.60 and N?0.519A1+0.292Ti, with the balance being Fe and inevitable impurities; and a microstructure in which bainite is present in an area ratio of 95% or more, where the microstructure contains prior austenite grains with a grain size number of 6 or more, and strength variation is 100 MPa or less.

Abstract: An image processing apparatus including a memory, and a processor configured to make a display device display an image captured by an image capturing device, measure a time for which a hand region remains still when detecting the hand region in a first specific shape corresponding to a designation operation of designating a part in the image, identify the part designated by the designation operation when the time for which the hand region remains still reaches a predetermined time, and make a display device display an image resulting from execution of predetermined image processing for the identified part when at least one of a hand region in a second specific shape and a specific movement of a hand region is detected in the image captured by the image capturing device.

Abstract: A method includes detecting a plurality of reference objects from an image, acquiring a plurality of contents, virtually arranging the plurality of contents based on position information of each of the plurality of contents, determining whether an overlap occurs between display regions of at least some contents among the plurality of contents virtually arranged, when the overlap occurs, changing at least one of a display size and a position of the at least some contents overlapping each other to remove the overlap, generating display data for displaying another image including the plurality of contents based on at least one of the changed display size and the changed position of the at least some contents, and the position information of contents other than the at least some contents, and controlling a display to display the another image based on the display data.

Abstract: A book detection apparatus detects a plurality of surface regions on the basis of three-dimensional measurement data that is obtained by a three-dimensional sensor and that falls within a search area, and determines, when a positional relationship between two surface regions among the plurality of surface regions satisfies a positional condition corresponding to a positional relationship between two opened pages of an opened book, the two surface regions as a book region that includes the book.

Abstract: An interactive projector includes: a base placed on a projection surface; a leg configured to raise with tilting from the base towards the projection surface; a projecting unit, mounted on the leg on the side of a projection surface, configured to project first image; a reflector, provided at a free-end portion of the leg, configured to reflect the image projected from the projecting unit towards the projection surface; and an image pickup unit, mounted on the reflector, configured to photograph the projection surface and output second image to an electronic device that outputs, to the projecting unit, the first image that is generated based on the second image.
