摘要： A server system with a cooling ability that can cope with an increase in the amount of heat generated by a CPU of a server module detachably mounted on a blade server. The server module includes an enclosure accommodating therein a motherboard on which a CPU, memory, and the like are mounted, and part of a boil cooling device for cooling heat generated by the CPU. A fan accommodated in a fan module is adapted to blow air into the server module through an opening of the server module enclosure. The boil cooling device includes a first heat transmission member disposed in the server module enclosure, a second heat transmission member disposed outside the server module enclosure, and a plurality of pipes connecting them. The first heat transmission member is a box body with an internal space for hermetically sealing a refrigerant therein, one external planar face of which is thermally connected to the CPU and the other external planar face of which is provided with a heat sink. The second heat transmission member is disposed in the fan module unit, and a heat radiation member provided for the pipes forms an airflow passage together with the motherboard.

摘要： An electric power-steering device 100 comprises a steering mechanism 10, an electric motor 20 which outputs an assist force to this steering mechanism 10, a transmission mechanism 30 which comprises toothed pulleys 31, 32 and a toothed belt 33 and transmits the output power of the electric motor 20 to the steering mechanism 10, and a torque limiter 40 which sets a limit on the extent of the torque transmitted between the electric motor 20 and an output member (11) of the steering mechanism 10. In this electric power-steering device 100, a variation lower limit of a teeth jump torque at which a teeth jump occurs between the toothed pulleys 31, 32 and the toothed belt 33 is set at a value larger than a variation upper limit of a limit torque in the torque limiter 40. Therefore, when a torque which exceeds a normal torque occurs at a motive-power transmission system between the electric motor 20 and the steering mechanism 10, the torque limiter 40 functions (acts) before a teeth jump occurs in the transmission mechanism 30.
