Abstract: PROBLEM TO BE SOLVED: To provide a vehicle-use tandem rotary electric machine that prevents the temperature rise of a rectifier device while preventing the increase of its size and weight.
SOLUTION: A positive diode 81 and a negative diode 82 constituting rectifying elements of a rectifier device 8 of the vehicle-use tandem rotary electric machine dissipate heat to a stator core 33 of a second rotary electric machine 3 acting as a heat sink through a housing 13. The stator core 33 is larger than a stator core 23 in size and weight and does not supply electric power to a highly frequent load. Thereby, the effect of preventing the temperature rise of the positive diode 81 and the negative diode 82 caused by the stator core of the second rotary electric machine can be improved.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of component items, a diameter of an ignition device for an internal combustion engine, and cost, in the ignition device where an ignition plug 2 and ignition coil 3 are integrally mounted to a cylinder head. SOLUTION: The ignition device has a cylindrical case 1 where a part for storing components of the ignition plug 2 and a part for storing components of the ignition coil 3 are integrally formed, and the case 1 is made of magnetic and conductive metal material. The case 1 including the part for storing components of the ignition coil is integrally formed of the metal material, so that the case 1 itself has a function of the outer peripheral core of the ignition coil. Therefore, the number of component items, the diameter of the ignition device, and the cost are reduced. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To improve the cooling performance of an armature that is an electrical heating element in a magnet generator with a stator clutch especially even without using any conductors with high heat resistance, to suppress the temperature increase of a permanent magnet, and to make small the reduction of generation output. SOLUTION: In a magnet generator with a starter clutch where a stator clutch 5 is mounted onto the end face of a rotor 1, a window hole 20 for cooling is formed onto the end face of the rotor 1 while the window hole is extended from one part of a stator clutch clamping seat 100 in that the stator clutch 5 is mounted to the outer-periphery side. The window hole 20 for cooling being exposed at the outer-periphery side of the stator clutch 5 is covered with a fan 10, at the same time, an opening part 200 is provided on the rotary-direction side of the rotor 1 of the fan 10, and the angle of the blade of the fan 10 is bent forward to the rotary-direction side of the rotor 1.
