  • Patent number: 10319344
    Abstract: A system consisting of a plurality of terminals storing image data and an image displaying device which are connected with each other through a network capable of two-way communication has the disadvantage of decreasing in throughput on account of slow image data transfer over the network. The image displaying device performs two-way communications with each of the terminals by a communication means at the display device side. Also, the image displaying device acquires image data from a relevant terminal while instructing other terminals to suspend transmission by the image data acquisition controlling means, thereby suspending transmission of image data. The image displaying device displays images by the image displaying means based on the thus acquired image data.

  • Publication number: 20190148155
    Abstract: In a substrate processing method, electrons having a first energy are supplied from an electron beam generator into an inner space of a chamber body of a substrate processing apparatus to generate negative ions by attaching the electrons to molecules in a processing gas supplied to the inner space. Then a positive bias voltage is applied to an electrode of a supporting table that supports a substrate mounted on thereon in the inner space to attract the negative ions to the substrate.

  • Patent number: 9971419
    Abstract: An interactive projector is provided with a projection section adapted to project an image on a screen surface, a detection section, and a correction section. The detection section detects presence or absence of contact of the pointing element with the screen surface based in a relationship between a difference between a Z-coordinate value of the pointing element and a Z-coordinate value of the screen surface, and a difference threshold value set in advance. The correction section corrects at least one of the Z-coordinate value of the screen surface, the Z-coordinate value of the pointing element, and the difference threshold value based on a history of the Z-coordinate value of the pointing element.

  • Patent number: 9934947
    Abstract: A plasma processing apparatus includes an electrode to which a high frequency for plasma generation is applied and which serves as a mounting table for a target object. The plasma processing apparatus further includes a high frequency generation unit, a distortion component extraction unit and a waveform correction unit. The high frequency generation unit generates the high frequency by using waveform data including a set frequency component having a predetermined frequency. The distortion component extraction unit extracts a distortion component given to the high frequency in a path for transmitting the high frequency generated by the high frequency generation unit to the electrode. The waveform correction unit corrects the waveform data by combining an antiphase component obtained by inverting a phase of the distortion component and the set frequency component of the waveform data used for generation of the high frequency.
