    摘要: A steering device for an amusement car including a drive wheel mounted off-center on a wheel shaft to provide a rotation force for quick and automatic recovery of the steering device to steer the car away from an obstacle that is encountered during use. The drive wheel being mounted to the wheel shaft in an area bounded by a distance equal to the radius of the drive wheel and a distance equal to the diameter of the drive wheel, both measured from the center of the wheel shaft.

    摘要: Disclosed are a radiant heat circuit board and a method for manufacturing the same. The radiant heat circuit board, which is used to mount a heat emitting device thereon, includes a metallic plate including a metallic protrusion having a solder to which the heat emitting device is attached, a bonding layer on the metallic protrusion, an insulating layer on the metallic plate to expose the metallic protrusion, and a circuit pattern on the insulating layer. Heat emitted from the heat emitting device is directly transferred to the metallic plate by providing the metallic plate including a heat radiation protrusion under the mounting pad, so that heat radiation efficiency is increased. The surface of the heat radiation protrusion is plated with an alloy including copper, thereby improving the adhesive property with respect to the solder, so that the failure rate is reduced.
