The fed members differ in the load applied and each of the fed members is independently designed to accommodate its respective load as well as to accommodate a single feeding member. While the respective loads differ, only the design of the respective fed member is modified to accommodate the different load value while no modifications to the single feeding member are made.

摘要： A non-contact electric power transmission apparatus including a power supply unit and a load unit. The power supply unit has a first oscillation circuit, a signal secondary winding, a filter circuit, and a driving control circuit. The load unit has a power secondary winding, a signal primary winding, and a second oscillation circuit. The first oscillation circuit has a power primary winding and intermittently oscillates at a first oscillation frequency. When the load unit is placed at a predetermined position with respect to the power supply unit, since signals are induced in the power secondary winding by the signals in the power primary winding, the second oscillation circuit oscillates at a second oscillation frequency which is different from the first oscillation frequency. The signals from the second oscillation circuit are transmitted from the signal primary winding to the signal secondary winding. When the signals having the second oscillation frequency is input from the signal secondary winding to the driving control circuit through the filter circuit, the driving control circuit controls the first oscillation circuit to successively oscillates.

摘要： A driving unit of the present invention comprises a moving element, an elastic body configured to support the moving element, a permanent magnet fixed on said moving element, an electromagnet disposed to be opposed to said permanent magnet, and a controller. The moving element and the elastic body constitute a resonance system. The electromagnet includes a magnetic material and a coil wounded around the magnetic material. The controller magnetizes the magnetic material by feeding a current through the coil and gives a vibration force to the moving element by magnetic force acting between the magnetic material and the permanent magnet. The feature of the present invention resides in that the controller determines a current waveform necessary for an intended motion of the moving element, and applies a voltage to the coil intermittently so that a current in the form of the current waveform flows through said coil.

摘要： An electrostatic atomization device provided with a transformer including primary and secondary coils. A switching element is connected in series to the primary coil. A switching element drive circuit provides the switching element with a pulse signal to perform a switching operation and generate high voltage from the secondary coil. A discharge unit including a discharge electrode performs electrostatic atomization on liquid supplied to the discharge electrode to generate charged fine liquid droplets when high voltage generated by the secondary coil is applied to the discharge electrode. The switching element drive circuit generates a pulse signal having an oscillation frequency set so that the transformer has drooping characteristics that prevent air discharge from occurring between the discharge electrode and ground even when load on the discharge unit varies and prevents the generation of ozone having a predetermined concentration or greater when the liquid undergoes electrostatic atomization.
