  • Patent number: 9876482
    Abstract: A matching unit includes a directional coupler for detecting a travelling wave and a reflected wave; a matching circuit including a first variable capacitance capacitor, a second variable capacitance capacitor and an inductance; and a control unit for controlling VC1 and VC2 of the first and the second variable capacitance capacitor by calculating a reflection coefficient based on the travelling wave and the reflected wave. When a distance between the calculated reflection coefficient and a circle described by a trace of the reflection coefficient which passes through a matching point on a Smith chart is greater than a predetermined value, the control unit changes VC2 of the second variable capacitance capacitor and the calculated reflection coefficient to make the distance within the predetermined value. When the distance becomes within the predetermined value, the control unit changes VC1 of the first variable capacitance capacitor and makes the calculated reflection coefficient smaller.

  • Publication number: 20170243332
    Abstract: In a case where noise reduction processing is performed on an image acquired by radiography, the noise reduction processing is prevented from being influenced by other image processing performed in advance. A structure determination unit determines a structure present in a target pixel of a preprocessed captured image. A first image processing unit performs a predetermined image processing based on a determination result of the structure present in the target pixel of the preprocessed captured image. A second image processing unit performs image processing different from the predetermined image processing on an image acquired through the predetermined image processing performed by the first image processing unit.
