Abstract: A display control method includes displaying a first small image generated by shrinking a first image generated by an application program, on an actual display provided in an output device, receiving an operation on the first small image, drawing, on a virtual display, a second image generated by the application program executing processing corresponding to the operation on the first small image, displaying the second image drawn on the virtual display, using a display device, and displaying a second small image generated by shrinking the second image, on the actual display.

Abstract: A semiconductor device that can be scaled down or highly integrated is provided. The semiconductor device includes a first layer and a second layer over the first layer. The first layer and the second layer each include a transistor. The transistor in the first layer and the transistor in the second layer each include a first oxide, a first conductor and a second conductor over the first oxide, a first insulator placed to cover the first conductor, the second conductor, and the first oxide, a second insulator over the first insulator, a second oxide placed between the first conductor and the second conductor over the first oxide, a third insulator over the second oxide, a third conductor over the third insulator, and a fourth insulator in contact with a top surface of the second insulator, a top surface of the second oxide, a top surface of the third insulator, and a top surface of the third conductor.

Abstract: For treating bilge containing solid matters and emulsion securely, an oily water separator includes a first treater 1 for separating oil ingredient roughly from bilge by gravity separation and removing fine suspended matter from the bilge by sand filtering, and a second treater 10 for separating and removing oil ingredient remained in the bilge treated by the first treater. The first and second treaters 1, 10 are connected directly by a feeding pipe 8. The first treater 1 includes an oil discharge portion 5a above an oily water, inlet 2 and a filtering sand layer 3 below the oily water inlet 2. The second treater 10 includes a coalescer 19 in a lower room 29 to communicate with the upper room.
