Abstract: A tank is disposed beneath a floor for storing methanol and water. A reforming unit is disposed beneath the floor for generating hydrogen from methanol and water supplied from the tank. A fuel cell is disposed beneath the floor for generating electricity from an electrochemical reaction of hydrogen generated by the reforming unit and oxygen in air. A secondary battery is disposed beneath the floor for storing electricity generated by the fuel cell. In this way, mechanisms for generating electricity from air, methanol, and water are centralized.

Abstract: The invention relates to an improvement in the design of the magnetic circuit in a permanent-magnet rotary machine, e.g., a servomotor, with an object to stabilize the output of the motor with respect to temperature variation. The inventive improvement is in making the value of (A.sub.m B.sub.m)/(A.sub.y B.sub.ys), which is called the area factor .alpha., larger than 1 but smaller than 5, A.sub.m and B.sub.m being the cross sectional area and magnetic flux density, respectively, in the magnetic circuit of the permanent magnet and A.sub.y and B.sub.ys being the effective cross sectional area and saturation magnetic flux density at room temperature, respectively, in the magnetic circuit of the yoke.

Abstract: An electric generator organization, particularly adapted for small vehicles such as motorcycles, is described in which a rectifier mechanism electrically disposed between the stator and the rotor is mechanically connected to the rotor for rotation therewith during engine startup and disconnected therefrom during periods of normal engine operation. An operating circuit enables efficient transmission of electric current from the battery to starting coils in the generator only during the period of engine startup. During periods of normal engine operation, the transmission of electric current is from generating coils in the generator to the battery. Included in the operating circuit is an engine operation detector that prevents excessive current feed from the generator coils to the rectifier mechanism.
