Abstract: An image control processing section controls a game playback device to employ an advertising image being an image for advertising a product or a service, as a character image used in a game screen. The image control processing section comprises an advertising image information database that stores advertising image information, which is information related to a product or service including advertising image data, and an advertising image selection device that selects an advertising image of a product having a better advertising effectiveness from the advertising image database, by referencing information from among; information related to a store where a user terminal is installed, a period of time, a date, a day of the week, and a time elapsed from when a user using a user terminal sits down, taken as a start time.

Abstract: In order to reflect a difference between an actual value and a target value of a strip profile of a product at a tandem mill, the load pattern for the next rolled material is changed in accordance with the difference of a target value and an actual value of the crown ratio of the previously rolled material. In this case, there are calculated the coefficients of the crown ratio/load, and load/load ratio. The crown ratio difference is sequentially given to the previous stand in accordance with the load ratio to determine the change amount of the load ratio at each stand. The load pattern for the next rolled material is given while considering the change amount, to calculate the delivery thickness at each stand carrying out the rolling operation.

Abstract: In setting roll gaps of a rolling mill having stands arranged in tandem, the resistance to deformation of a workpiece in each of the stands is calculated on the basis of a cumulative strain in each stand, with strain of the workpiece which is in an entrance side of the mill and in a soaked state being zero. The resistance to deformation of the soaked workpiece is obtained in each stand, so that the accuracy of estimation of the resistance to deformation is improved. Thus, a precise roll gap setting becomes possible, resulting in a product of a thickness accurately coincident with an objective thickness.
