Abstract: Disclosed is an electric power generating apparatus. The electric power generating apparatus includes a casing that is made of a nonmagnetic material and has an outer surface and an interior space, a guide shaft that is made of a nonmagnetic material and provided in the interior space while being supported by the casing, a permanent magnet provided to the guide shaft so that the permanent magnet is capable of being reciprocated, a coil provided on an outer circumference of the interior space, a shield case to cover the outer surface of the casing, the shield case being made of a magnetic material, and an electric circuit unit to output an electric energy generated in the coil by reciprocating the permanent magnet.

Abstract: Provided is a fan motor apparatus. The fan motor apparatus includes a rotor and a stator. The rotor includes a blade. The stator includes a rotor supporting mechanism, a supporting member, and a vibration insulation member. The rotor supporting mechanism rotatably supports the rotor. The supporting member supports the rotor supporting mechanism. The vibration insulation member is provided between the rotor supporting mechanism and the supporting member. The stator is capable of regulating relative movement of the rotor supporting mechanism and the supporting member.

Abstract: A motor includes a shaft that serves as a rotation center when a rotor is rotated with respect to a stator, a bearing that supports the shaft in a circumferential direction of the shaft, a thrust bearing that supports one end of the shaft in a thrust direction of the shaft, a magnet that is fixed to the rotor and alternately magnetized to different poles in a rotational direction of the shaft, a core that is fixed to the stator and disposed to face the magnet in a radial direction of the shaft, a coil that are wound around the core, and a magnetic shield that shields leakage flux leaking from the magnet to the coil. A magnetic center of the core is offset from a magnetic center of the magnet in the thrust direction, so that the shaft is attracted to the thrust bearing.

Abstract: The rotation of axial-flow blades permits air entered through an inlet port to exit directly to outside of a case in the axial direction, and the rotation of centrifugal blades permits air entered through the inlet port to exit through a side surface outlet port to the outside of the case in the centrifugal direction. Accordingly, the amount of flow of air exiting from inside of the case can be increased so that the amount of heat dissipation is increased. It is therefore able to provide a cooling apparatus and electronic equipment mounting the cooling apparatus with improved cooling efficiency while achieving a small thickness.

Abstract: A fan motor having a small thickness and its impeller's blades formed to have a longer length in the diametrical direction than a width in the axial direction. Since the blade of the fan motor has a tooth structure or chamfers at its edge end in the diametrical direction, turbulence is forcibly evoked in an airflow to promote the turbulent diffusion, thereby suppressing the trailing vortex and reducing the aerodynamic noises, and thus the ventilation efficiency is improved.

Abstract: A fan motor having a small thickness and its impeller's blades are formed to have a longer length in the diametral direction than a width in the axial direction. Since the blade of the fan motor has a tooth structure or chamfers at its edge end in the diametral direction, turbulence is forcibly evoked in an airflow to promote the turbulent diffusion, thereby suppressing the trailing vortex and reducing the aerodynamic noises, thus the ventilation efficiency is improved.
