Abstract: Provided is a program for a game where a plurality of ally characters and an enemy character are made to battle with each other, the program causing an electronic device to execute: determining whether the enemy is in a special-attack target state where the enemy becomes a target of a special attack; setting the allies disposed within a predetermined range of the enemy in the game field, in a state of being able to execute the special attack, if in the special-attack target state; allowing the allies to execute the special attack in the state of being able to execute the special attack; determining whether the executed special attack succeeded; increasing correction points when the special attack succeeded; decreasing the correction points according to a period during which the correction points are not increased; and correcting parameters associated with the allies when the correction points satisfy a correction condition.

Abstract: A fan motor includes an electric motor including a stationary unit and a rotary unit, an impeller including blades and rotating together with the rotary unit, a housing accommodating the electric motor and the impeller, lead wires connected to the electric motor and extending radially outward, and a guide member. The housing includes a tubular portion extending along a rotation axis and accommodating at least a part of the impeller, a flange portion protruding radially outward from at least a part of the tubular portion, a lead wire outlet port provided in at least a part of the tubular portion, and a vertical groove communicating with the lead wire outlet port and penetrating the flange portion in an axial direction. The guide member is disposed inside the vertical groove, and at least a part of the lead wires is accommodated radially inward of the guide member in the vertical groove.

Abstract: An impeller includes a hub rotated about an up-down axis and inclined blades disposed circumferentially on a hub's outer circumferential surface. The outer circumferential surface includes a first surface including a portion axially overlapping the blade above its joined portion to the blade, a second surface including a portion axially overlapping the blade below the joined portion, and a connecting portion connecting a rotating-direction rear end of the first outer circumferential surface and a rotating-direction front end of the second outer circumferential surface. The connecting portion is arranged forward of a rotating-direction blade front edge. A distance from the axis to a first point, positioned at the rotating-direction rear end of the first outer circumferential surface, is not shorter than that from the axis to a second point, positioned at the rotating-direction front end of the second outer circumferential surface and at the same axial position as the first point.

Abstract: In a fan, a housing includes decreased thickness portions and increased thickness portions arranged alternately in a circumferential direction. A distance between a central axis and an edge increases from an air inlet toward an air outlet. An inner circumferential surface has a minimum radius smaller than a distance between the central axis and an outermost portion of the edge. At a boundary between upper and lower housing portions of the housing, the inner circumferential surface has a radius greater than the distance between the central axis and the outermost portion of the edge. The increased thickness portions include component fastening structures defining a fastening structure arranged to fit the upper and lower housing portions to each other.

Abstract: A fan includes a stationary portion, a rotating portion, and a plurality of blades. The stationary portion includes a stator, an integral one-piece molded metal bearing housing, a bearing portion in the bearing housing, and a molded resin base portion supporting the bearing housing. The rotating portion includes a rotor holder, a rotor magnet, and a shaft. The bearing housing includes a cylindrical portion, and a protruding portion extending radially outwards from a lower portion of the cylindrical portion. The cylindrical portion includes a groove portion extending in an axial direction and arranged in a circumferential direction. The groove portion is joined to a region on the lower side of the protruding portion along a connecting position between the cylindrical and protruding portions. A resin on an upper side of the protruding portion, a resin on a lower side, and a resin in the groove portion are continuous.

Abstract: A motor includes a cover made of a resin material. The cover includes a first annular portion arranged to extend in an annular shape above coils, a side wall portion arranged to extend downward from an outer circumferential portion of the first annular portion, and a second annular portion arranged to extend radially outward or radially inward from a lower end portion of the side wall portion along an upper surface of a circuit board. The side wall portion is arranged to extend in an axial direction while filling in gaps between teeth on a radially inner side of radially outer end surfaces of the teeth. The coils are covered by the cover to be protected from dust, water droplets, etc. The radially outer end surfaces of the teeth are exposed from the cover, and are thus arranged to be in radial proximity to a rotor magnet.

Abstract: A serial axial fan unit includes first and second motors with their base portions, i.e., first and second base portions axially facing each other. A motor gap is arranged axially between the first and second base portions. An axial length of the motor gap is preferably in a range from approximately 0.3 mm to approximately 2.0 mm. This configuration reduces transmissions of vibration of each of the first and second motors to the other, thereby reducing vibration interference between the first and second motors.

Abstract: Bearing unit furnished with a bearing retaining part, the bearing retaining part formed from a single, seamless component and furnished with a cylindrical section disposed on the outer periphery of a sleeve of the bearing unit, and with a bottom section closing over the sleeve and the cylindrical section along their undersides. An attracting magnet is disposed on the bottom-section side of the bearing retainer, for magnetically attracting axis-wise the lower-end portion of a shaft of the bearing unit. A magnet holder, formed from a magnetic material, is disposed on the underside of the attracting magnet, with the magnet holder being attached to the bearing retainer.
