    • A self-oscillating vibrator exciting circuit utilizing a drive transistor that operates in a switching mode. The ON-period of the transistor is determined by base/emitter inductance and capacitance and base/collector capacitance, while the OFF-period of the transistor is determined by collector/emitter inductance and capacitance. The vibrator is connected between transistor collector and emitter, and the ON-period frequency of the transistor is set in the neighborhood of the resonance frequency of the vibrator so that the vibrator exciting circuit oscillates generally at the resonance frequency of the vibrator.
    • 利用在切换模式下工作的驱动晶体管的自振荡振子激励电路。 晶体管的导通周期由基极/发射极电感和电容以及基极/集电极电容决定,晶体管的截止周期取决于集电极/发射极的电感和电容。 振动器连接在晶体管集电极和发射极之间,晶体管的导通周期频率设定在振动器共振频率附近,使得振动器激励电路大致以振动器的共振频率振荡。

    • To provide a small sized reactor with which it is possible to reduce the volume of a core and decrease electrical power losses.[Solution] A reactor has a first magnetic body and a pair of mutually insulated coils insulated from the first magnetic body while being arranged so as to surround the first magnetic body, and positively coupled to each other in response to a signal input between one end of each coil. The first magnetic body has a first and a second end portions, and the first and the second end portions are formed without directly facing each other via a space where the first magnetic body does not exist, and an output signal is output from between the other end of each of the pair of coils on the basis of the input signal input between the one end of each of the pair of coils.
