Abstract: A method for controlling the respective input voltages transmitted to a servomotor that tilts the ladle such that the molten metal that flows from the ladle drops accurately into the pouring gate in the mold, a servomotor that moves the ladle back and forth, and a servomotor that moves the ladle up and down, by using a computer. In the method, a mathematical model of the area on which the molten metal that flows from the ladle will drop is produced, and then the inverse problem of the produced mathematical model is solved. In view of the effect of a contracted flow, the position on which molten metal drops is estimated by the estimating device for estimating the pouring rate and the estimating device for estimating the position on which molten metal will drop.

Abstract: The purpose of the present invention is to provide a method for accurately dropping molten metal that flows from a ladle into a pouring gate in a mold. The present invention includes a method for controlling the respective input voltages transmitted to a servomotor that tilts the ladle such that the molten metal that flows from the ladle drops accurately into the pouring gate in the mold, a servomotor that moves the ladle back and forth, and a servomotor that moves the ladle up and down, by using a computer. In the method, a mathematical model of the area on which the molten metal that flows from the ladle will drop is produced, and then the inverse problem of the produced mathematical model is solved. In view of the effect of a contracted flow, the position on which molten metal drops is estimated by the estimating device for estimating the pouring rate and the estimating device for estimating the position on which molten metal will drop. Then the estimated position is calculated by a computer.

Abstract: A display device provided with a screen, comprising: an optical filter having a blind sheet that comprises a plurality of semitranslucent layers having translucence arranged side-by-side extending in a horizontal direction and having a predetermined thickness in a vertical direction, and a plurality of transparent layers which are disposed between the semitranslucent layers and which are of a higher translucency than that of the semitranslucent layers and of a greater thickness than the thickness of the semitranslucent layers; and an adhesive member for sticking the optical filter to the screen, wherein the ratio of the transmittance of a limit angle of the screen with respect to the transmittance of the optical filter at the center of the screen is at least 0.10 and not more than 0.50.

Abstract: A body antireflection layer is provided on a display surface of a display device body. A first antireflection layer and a second antireflection layer are provided on both sides of an optical filter that is opposed to the display surface by a predetermined gap. A light-blocking screen frame layer is provided on the optical filter between a light-transmissive base and the first antireflection layer near the display surface at a peripheral area corresponding to an outer periphery of the display device body. A color difference between a position of the screen frame layer and a position of a display area of the display device body is 40 or less. A border between the display area and the screen frame layer becomes difficult to be visible, so that the optical filter can be recognized by users as an integral surface having no border over the entire surface of the optical filter.

Abstract: An optical filter 17 is attached to the display screen surface of a flat display panel 3 of a flat display apparatus. The optical filter 17 is constituted of a lamination of an electromagnetic-wave blocking sheet 17A, an infrared-radiation absorbing and color-tone correcting sheet 17B and an ambient light antireflective sheet 17C.
