  • Publication number: 20200234643
    Abstract: A first storage capacitor is provided with respect to a data line. A pixel circuit includes a first transistor supplying current according to a voltage between a gate and a source, a light emitting element emitting light corresponding to current supplied by the first transistor, and a second transistor which is turned on or off between the data lines and the gate node. In a first period, an initial potential is supplied to the data line by turning on the second transistor, and in a second period, a data signal of a potential corresponding to a gradation level is supplied to the other end of the first storage capacitor by turning on the second transistor. After the second period, the second transistor is turned off.

  • Publication number: 20200001401
    Abstract: According to a laser cutting method, a processed part is laser-cut so that the processed part doesn't drop off from a sheet-shaped workpiece. In the laser cutting method, a cut slit of a pressing protrusion, which is curved due to a laser cutting process along an outline of the processed part and then presses a peripheral surface of the processed part, is preliminarily formed around the processed part to be cut out from the workpiece. Then, the laser cutting process is carried out along the outline of the processed part. The pressing protrusion curves toward the processed part due to the laser cutting process of the processed part, and then the processed part is retained by the pressing protrusion.

  • Patent number: 5003532
    Abstract: A multi-point conference system for making a video conference includes a center unit having a controller and an image selector, and three or more stations respectively coupled to the center unit, where each station includes at least one camera for picking up an image to output an image data, a display for displaying an image based on an image data and a request part for making a request. The controller initially sets master, sub and participating stations in conformance with a predetermined rule. The image selector automatically supplies the image data from the master station to the sub and participating stations to be displayed on the display thereof and supplies the image data from the sub station to the master station to be displayed on the display thereof.
