PROBLEM TO BE SOLVED: To provide a power supply system by which even when a power source device and a power receiving device are connected by an optional power cable, an input voltage or input current of the power receiving device can be controlled to a predetermined input setting value.SOLUTION: A power receiving device detects an input voltage or input current inputted from a power cable, and transmits the detected input voltage or input current as power receiving side information to a power source device via the power cable. On the basis of the power receiving side information received from the power cable, the power source device controls an output value of an output voltage or output current outputted to the power cable so that the input voltage or input current inputted to the power receiving device converges to a predetermined input setting value.

PROBLEM TO BE SOLVED: To provide a low-cost switching power supply, by making the structure of a flyback transformer simple and by detecting an output voltage at the primary side. SOLUTION: A first switching element, which is self-oscillated by a voltage impressed from a drive coil of the flyback transformer to excite an exciting coil, is inserted between an exciting coil and a DC power supply. The drive coil is directly connected to one end of the exciting coil, and an output voltage detecting portion is provided for detecting a voltage corresponding to an output voltage of the exciting coil. An error detecting portion that compares a detected voltage with a reference voltage is provided in the output voltage detecting portion. A switching control device is connected to this error detecting portion. Based on the magnitude of a voltage difference detected by the error detecting circuit, a time constant circuit of the switching control device is made variable to control the ON time of a first switching element in such a way that the output voltage becomes constant by controlling the on-off of a second switching element.

PROBLEM TO BE SOLVED: To provide a capacitive touch panel having high accuracy in detecting an input operation position.SOLUTION: A potential between a uniformly conductive layer laminated on an input operation surface and a reference node is vibrated at a natural frequency f. A signal detection circuit detects a natural oscillation signal with the natural frequency f appearing in each detection electrode relatively to the reference node. Then, signal voltages are compared with each other to detect an input operation position. The signal voltage of the natural oscillation signal with the natural frequency f is not detected in an input standby state, so that the signal voltage appearing in each detection electrode due to the approach of an input operation body can be detected with high accuracy.
