  • Electric power interchange system
    Patent number: 8990114
    Abstract: In a power interchange system, a power generated by a power generation device is interchanged between power consumers which receive an electric power supply from a power supply system. The amount of electric power sold by a power consumer is defined as an amount of selling power, and the amount of electric power that the power consumer demands from another electricity consumer is defined as an amount of purchasing power. Power interchange groups are formed, in which power consumers interchanges an electric power thereamong, and each power consumer is provided with a power control device which manages the electric power from the power generation device.
    Type: Grant
    Filed: November 2, 2010
    Date of Patent: March 24, 2015

  • Linear oscillator and electrically driven toothbrush
    Patent number: 7315098
    Abstract: A linear oscillator and an electric toothbrush capable of emitting a low noise and of being assembled compact are provided. The linear oscillator, which reciprocates a shaft in an axial direction thereof, includes a plunger movable together with the shaft in the axial direction of the shaft, an elastic member for applying an axially acting resilient force to the plunger, an electromagnetic driving unit operable to reciprocate the plunger in the axial direction of the shaft at a resonant frequency when an alternating current is supplied thereto, and a fixing member restricting rotation of the plunger about an axis thereof within a predetermined angle. The electric toothbrush includes the linear oscillator and a brush head attached to the shaft for use in brushing teeth.

  • Linear oscillator
    Patent number: 6958553
    Abstract: A linear oscillator includes a reciprocating moving part, a case to contain the moving part, and an amplitude control spindle moveably supported in the case. The moving part and the amplitude control spindle reciprocate at a frequency approximately equal to the resonance frequency of the linear oscillator.
