摘要： The present invention provides a switching circuit and an electronic switching component having a switching semiconductor device to perform switching between a conducting state and a non-conducting state of a conducting path to thereby reduce the power loss thereof and a control method thereof. In the present invention, at least two FETs 11 and 12, wherein the FET 11 has a faster switching time and the FET 12 has a lower ON resistance. Active terminals (drains and sources) of the FETs 11 and 12 are connected to each other in parallel. By employing these FETs 11 and 12, the conversion between an ON-state and an OFF-state of the conducting path is performed. In converting from the non-conducting state to the conducting state, the control circuit 13 first turns on the FET 11 and then turns on the FET 12 when if a voltage between terminals of the FET 11 reaches around a saturation value thereof. In converting from the conducting state to the non-conducting state, the control circuit 13 first turns off the FET 12 and then turns off the FET 11 when if a voltage between terminals of the FET 11 reaches around a saturation value thereof.

摘要： A wireless charging system includes a first winding portion, a second winding portion which is disposed with an interval between the first winding portion and the second winding portion in an axis direction of the first winding portion, and a pair of magnetic members which are disposed so as to sandwich the first winding portion and the second winding portion in the axis direction. In this case, protrusion portions which protrude toward the other magnetic member are provided in one magnetic member. Also, the magnetic member is held so as to be able to move forward and backward toward the other magnetic member. As a result, since the coefficient of magnetic coupling between a transmitting unit and a receiving unit during charging is enhanced, a charging efficiency can be enhanced.

Eight array antennas, each of which is arranged in a manner similar to that of the array antennas of the application integrated circuit, are formed at intervals of 45 degrees around a rotation axis on an imaging process integrated circuit of a movable housing. A controller selects one of the eight array antennas of the imaging process integrated circuit so that a magnitude of a difference between a rotation angle of a movable housing and a rotation angle of the movable housing becomes equal to or smaller than 22.5 degrees based on the rotation angle of the movable housing, and controls a stepping motor so that a selected array antenna opposes to the array antenna on the application integrated circuit.
