Abstract: There are provided a mounted structure that is excellent in precision with little joining deviation and can be efficiently produced, an LED display, and a mounting method. There are provided a mounted structure, an LED display including the mounted structure, and a manufacturing method for mounting a semiconductor element on a substrate. The mounted structure is a structure in which the semiconductor element including a terminal is mounted on the substrate including an electrode. The mounted structure includes a joining portion that joins the terminal and the electrode to make the terminal and the electrode oppose each other, the electrode is a bump of a bulk metal material disposed on the substrate, and the joining portion is obtained by thermally fusing metal nanoparticles in ink containing the metal nanoparticles transferred onto at least one of the electrode or the terminal by using a microcontact printing method.

Abstract: Problems to be solved by the present invention relate to group control of moving objects in three dimensions, and the invention proposes a group control method, unlike conventional cumbersome methods, the method being stably provided with a function of causing a group to move in the same direction while preserving the aggregate form of the group, and with a function of causing the group to turn around a fixed point in the vicinity of an operational target. The method for three-dimensional group control of moving objects according to the present invention includes: setting, around individual moving objects, an interaction zone formed in a spherical or ellipsoidal three-layer structure of, sequentially from outside to inside thereof, an approach zone, a parallel-orientation zone and a repulsion zone; and employing, as an algorithm, a behavior model which comprises an approach rule, a parallel-orientation rule and a repulsion rule depending on the zone at which a neighbor moving object is present.

Abstract: The invention can reduce a system load within a sales server, and provides a more rapid service by simplifying the construction and the function of the sales server. In a utilization license solving server of the sales server, when a utilization right certificate is solved on the basis of a utilization license about contents desired by a user and is transmitted to a user terminal device, the utilization right certificate is stored and managed in a utilization right certificate managing section. In a service solving server, when a utilization right is solved on the basis of this utilization right certificate and is transmitted to the user terminal device, the utilization right is stored and managed in a utilization right managing section. Thereafter, when the utilization right is presented by the user, the contents corresponding to this utilization right are transmitted from a contents managing server to the user terminal device.
