  • Publication number: 20200118797
    Abstract: To provide a RF generating apparatus that enables apparatus size to be decreased and the cost reduced thereby while also improving power efficiency by performing a stable matching operation, and to provide a plasma treatment apparatus using said apparatus. This RF generating apparatus comprises a plurality of RF generators and matching units, the matching units being provided with only variable-capacity capacitors connected in parallel, thereby reducing the number of elements in terms of the variable-capacity capacitors. A matching calculation section for the RF generators determines, on the basis of traveling waves and reflection waves detected by a detection circuit, the capacity values of the variable-capacity capacitors for the matching units, while adjusting and determining the oscillation frequencies for oscillation circuits in the RF generators so as to decrease the level of the reflection waves. The plasma treatment apparatus uses this RF generating apparatus.

  • Patent number: 10623231
    Abstract: A communication terminal includes circuitry. The circuitry receives data of a whole image, data of a material image, and superimposition position information indicating a position where the material image is to be superimposed on the whole image, the data of the whole image, the data of the material image, and the superimposition position information being transmitted from another communication terminal. The circuitry superimposes the material image on the whole image at the position indicated by the superimposition position information. The circuitry causes a display to display a predetermined-area image, which is an image of a predetermined area of the whole image. When at least a part of the material image being superimposed is not displayed in the predetermined-area image, the circuitry changes the position where the material image is superimposed such that the material image is displayed at a predetermined position in the predetermined-area image.
