  • Publication number: 20140315427
    Abstract: Provided is a switch attached coaxial connector that improves an isolation characteristic between a common terminal and a closed terminal. In a normal state where a coaxial plug is not connected to the switch attached coaxial connector, a movable contact portion biased by a leaf spring piece portion elastically contacts a fixed contact piece portion so that a closed terminal and a common terminal are electrically connected to each other. When the coaxial plug is connected to the switch attached coaxial connector, the movable contact portion moves rearward from the fixed contact piece portion by the plug pin abutting against a plug contact portion so that the contact with respect to the fixed contact piece portion is disconnected and the electrical connection of the common terminal is switched from the closed terminal to the plug pin.

  • Patent number: 8823681
    Abstract: A method of outputting an input position of a touch panel is provided which can output an input position intended by an operator even if two or more different input positions are detected. When an input operation on a position different from a first input position is detected in a scan cycle after output of the first input position, the input position where the new input operation is detected is output as a second input position. Even if input operations on two or more different positions are simultaneously detected, only one input position is output.

  • Publication number: 20140192015
    Abstract: A touch input device includes a touch panel, a controller, and a cancellation electrode. The touch panel includes a sensor pattern and an operation surface arranged above the sensor pattern. The sensor pattern includes first electrodes and second electrodes insulated from one another and arranged in a grid. The controller applies a drive pulse signal to the sensor pattern and detects a touch location where the operation surface of the touch panel is touched based on changes in capacitance of the sensor pattern. A cancellation pulse signal is applied to the cancellation electrode during application of the drive pulse signal. The cancellation pulse signal has a phase inverted from that of the drive pulse signal.

  • Patent number: 8582320
    Abstract: There is provided a self-excited switching power supply circuit. A cycle control capacitor is charged with a flyback voltage generated in a feedback winding of a transformer during OFF operation period in which an exciting current does not flow in a primary winding of the transformer. An OFF control capacitor the charging speed of which changes ON operation period is charged with the charging voltage of the cycle control capacitor during the ON operation period in which an exciting current flows in the primary winding. The charging voltage of the cycle control capacitor is changed with a periodic cycle Tc sufficiently longer than an oscillation cycle To to make the oscillation cycle To of continuous oscillating operation variable based on the periodic cycle Tc. As a result, the frequency of a harmonic is distributed.

    Abstract: Provided is a power supply system which is capable of controlling a power receive device to have an input voltage or an input current at a predetermined input setting value even when a power supply device and the power receive device are connected to each other with an arbitrary power cable. The power receive device detects the input voltage or the input current inputted through the power cable and transmits a detected input voltage or input current as power-receive side information to the power supply device through the power cable. The power supply device controls the output value of an output voltage or an output current to be outputted to the power cable based on the power-receive side information received through the power cable so that the input voltage or the input current to be inputted to the power receive device is converged on a predetermined input setting value.

  • Patent number: 8547113
    Abstract: Changes of the stray capacitances of a large number of sensing electrodes can be detected simultaneously. Further, even if a stray capacitance changes slightly, an input operation to a sensing electrode can be detected based on elapsed time until the electric potential of the sensing electrode becomes the same as a threshold potential. The stray capacitance of a sensing electrode and a resistor of the sensing electrode form a CR time constant circuit. Charge or discharge of the stray capacitance of the sensing electrode is controlled while a rest time in a predetermined time ratio is set. A stray capacitance that slightly increases in response to an input operation made near a sensing electrode can be detected by detecting the stray capacitance in extended elapsed time until the electric potential of the sensing electrode becomes the same as the threshold potential.
