摘要： Provided is a reactor including a coil, and a core having an inner core portion arranged inside the coil and an outer core portion covering the outside of the coil. The inner core portion of the reactor has a higher saturation magnetic flux density than that of the outer core portion. The outer core portion has a lower permeability than that of the inner core portion, and is made of a mixture of a magnetic material and a resin. The case has a heat-transfer portion at an inner wall surface, as a heat-radiation structure for at least one of the coil and the inner core portion. With the reactor, even if the outside of the coil is covered with a core member, heat generated in the reactor can be effectively dissipated.

摘要： Provided is a reactor including a core; and a case housing the coil and the core, the core including an inner core portion arranged inside the coil and an outer core portion partly or entirely covering the outside of the coil, the outer core portion being formed of a mixture of a magnetic material and a resin. The coil is arranged such that the axial direction of the coil is substantially parallel to a bottom surface of the case. The difference in concentration of the magnetic material in the outer core portion in the axial direction of the coil is smaller than the difference in concentration of the magnetic material in the outer core portion in a direction along a side wall of the case. With the reactor, even if the outer core portion covering the outside of the coil is formed of the mixture of the magnetic material and the resin, a desirable inductance value can be easily achieved and the reactor can have good heat radiation performance.

摘要： Provided are a reactor which can perform step-up/step-down operations and soft switching with a small size and a smaller leakage inductance, and a method of adjusting a leakage inductance of the reactor. A reactor 1A includes a magnetic core 10A having a pair of inner core portions and forming a closed magnetic path, a main coil 11A having main coil elements 11a and 11b, and a sub-coil 12A having sub-coil elements 12a and 12b. The coil elements 11a and 12a are concentrically layered over one of the inner coil portions, and the coil elements 11b and 12b are concentrically layered over the other inner coil portion. One end portion of a wire 11w of the main coil 11A and one end portion of a wire 12w of the sub-coil 12A are joined to each other. A spacing between adjacent turns constituting the sub-coil element 12a (12b) is wider than that between adjacent turns constituting the main coil element 11a (11b). Thus, the reactor 1A has a smaller leakage inductance.

摘要： A compact reactor with excellent productivity and heat dissipation is provided. Reactor 1α includes a coil formed by spirally winding a wire 2w and a magnetic core 3 having an inside core portion inserted into the coil and an outside core portion 32 coupled to the inside core portion. These core portions form a closed magnetic circuit. The coil is covered with an inside resin portion 4 on the outer circumference thereof to form a coil molded unit 20α with its shape being held. The outer circumference of a combination unit 10 of the coil molded unit 20α and the magnetic core 3 is covered with an outside resin portion 5α. Reactor 1α does not have a case and is thus compact. A surface of the outside core portion 32 on the installation side (core installation surface 32d) is exposed form the outside resin portion 5α and is in direct contact with a fixed object, thereby achieving excellent heat dissipation. The provision of the coil molded unit 20α facilitates the handling of the coil during assembly of reactor 1α, thereby achieving good productivity.

摘要： It is provided a computer game apparatus for displaying an image of virtual space in which first and second characters locate, the image being viewed from a first point in the virtual space to a direction from the first point to a second point in the virtual space, comprising: a first processor for obtaining positions of the first and second characters in the virtual space; and a second processor for setting the first or second point in accordance with a distance between the positions of the first and second characters which are aligned in the direction in the virtual space. According to the present invention, when the characters approach each other in virtual space in a game, the first point in virtual space is raised, so that the image is displayed as virtual space is looked down. Therefore, since the first character manipulated by the player and the enemy character do not overlap in the image, the player can clearly observe the movements of the enemy character. And even when the two characters are fighting in close, since the character controlled by the player can quickly cope with an attack by the enemy character, the game will be more exiting.
