Abstract: An extreme ultraviolet light generation apparatus includes a target supply unit, a target passage detection device, a delay circuit, a laser device, a target image capturing device, and a processor. Here, the processor controls the vibrating element to provide irregular intervals between droplet targets adjacent to each other; generates integrated image data by integrating plural pieces of image data imaged at different times; specifies a position, in the integrated image data, of the droplet target most emphasized in the integrated image data; and sets a delay time based on a distance from a position of the most emphasized droplet target to a second detection position.

Abstract: Described herein are methods for producing a hot forged material in air using a Ni-based superalloy for the die. Also described herein are methods for producing a hot forged material, by placing on a lower die a material for hot forging, of which part or all of the surface is coated with a glass-based lubricant, and pressing the material for hot forging with the lower die and an upper die, to form a hot forged material, wherein one or both of the lower die and the upper die are made of a Ni-based superalloy, and wherein the surface of the die in contact with the material for hot forging is coated with a glass-based lubricant containing SiO2 as a main component, in which the total content of alkali metal oxides is 0 to 10.0% in mass %.

Abstract: The present disclosure is directed to a display control apparatus capable of reducing the possibility that predetermined information is not displayed despite the user intention. The display control apparatus includes a selection unit including an OSD display ON setting to display a video image with information superimposed thereon on a first display unit or OFF, an output unit, and a control unit configured to perform control so that in a case of the OSD display ON, the video image is displayed with predetermined superimposed information, whereas in a case of the OSD display OFF, if outputting the display to a second display unit is enabled, the video image is displayed with no predetermined superimposed information, whereas if outputting the display to the second display unit is disabled, either (1) the video image is displayed with the predetermined superimposed information or (2) an OSD item is displayed.

Abstract: A reproduction apparatus comprises a reproduction unit configured to reproduce image data from a recording medium; a detection unit configured to detect users; and a generation unit configured to generate, for each of a plurality of users, management information for distinguishing a portion that has been reproduced and a portion that has not been reproduced in the image data recorded in the recording medium.

Abstract: A reproduction apparatus comprises a reproduction unit configured to reproduce image data from a recording medium; a recognition unit configured to recognize users in response to reproduction of selected image data; and a control unit configured to inhibit deletion of the selected image data from the recording medium, in a case where there is a user, other than users recognized by the recognition unit, who has not reproduced the selected image data among a plurality of predetermined users.
