  • Patent number: 7417331
    Abstract: An engine drive electric generator apparatus converts the reciprocating movements of a pushrod of an internal combustion engine to electricity. Each generator apparatus has an electric coil surrounding a combustion engine pushrod, and a magnet on the pushrod that reciprocates with the pushrod through the coil. The relative reciprocating movement between the magnet and coil generates an electric current in the coil that is communicated with a battery of the vehicle to charge the battery.

  • Patent number: 7414339
    Abstract: [Problem] In a vehicular rotating electrical machine apparatus mounted in an electric vehicle or a hybrid electric vehicle, a rotating electrical machine apparatus in which a rotating electrical machine and an inverter unit to control the rotating electrical machine are integrated is miniaturized, and its torque characteristic and efficiency are improved. [Means for Resolution] Since an inverter unit 4 is cooled by cooling air forcibly formed by a cooling fan 28, the inverter unit 4 is efficiently cooled. Then, heat radiating fins 401a, 402a and 403a of heat sinks 401, 402 and 403 can be miniaturized, and consequently, the inverter unit 4 is miniaturized, and mountability of the inverter unit 4 to a rear bracket 19 is improved.

  • Patent number: 7408288
    Abstract: A determination is made whether a moving speed of a slider section with respect to a rod section in a piezoelectric actuator is lower than a predetermined speed. When the moving speed is lower than the predetermined speed, it is considered that a friction-bonded portion between the rod section and the slider section is in a fastened state or a nearly fastened state. A resonance frequency of the piezoelectric actuator or a frequency proximity to the resonance frequency is set as a driving frequency for the piezoelectric actuator. The slider section is moved in a reciprocating manner plural times with respect to the rod section. As a result, an abnormal state is eliminated from the piezoelectric actuator.
