摘要:
An apparatus for draw forming glass filaments includes a melt furnace 1 having a bottom plate 12 with a plurality of flow holes therein, each terminating in a conical nozzle tip 2. Cooling fins 10 extend outwardly from a water pipe 11 and are disposed between the rows of tips, and additional cooling is provided at least during the initial start-up period by air blown across the nozzle tips from a manifold 13 disposed opposite the water pipe. With such an arrangement the flow hole diameters may be increased, which results in an exponential increase in the molten glass flow rate and filament production rate, while still achieving smooth initial and stable continuous filament forming conditions.

To facilitate seeing of the image on a peripheral region which may become difficult to see as the screen size increases.A stereoscopic two-dimensional image display device includes a display unit 1 including an image display plane 1a on which an image is displayed; an image transfer panel 3 arranged apart from the image display plane, for imaging light emitted from the image display plane on an imaging plane 2 in a space, thereby displaying a stereoscopic two-dimensional image; and an optical path changing member (not shown) arranged between the image display plane and the imaging plane, for changing the optical path of the light emitted from the peripheral edge having a predetermined region constituting the image display plane. The optical path of light emitted from the peripheral edge is changed by the optical path changing means so that the light can be reached the eyes of a viewer 100 who sees at a near position.

A floating-image display module includes a display unit having an image screen for displaying a two-dimensional image, and an image transfer unit that is located far from the image screen of the display unit and that transfers light left from the image screen to image the light in a space to thereby display a floating image. The space is located at one side opposite to the image screen. The floating-image display module includes a supporting wall that is airtightly joined to the image display unit and the image transfer unit and that supports the display unit and the image transfer unit.
摘要:
It is an object to provide an image display device that does not damage a feeling of a three-dimensional shape of an object displayed as a floating image even if a contrast of a display unit is so bad that floating blacks occur. An image display device (100) is comprised of a display unit (10) having an image display surface (11) for displaying a two-dimensional image, an image transmitting panel (20) disposed apart from the image display surface (11), and a floating image display unit (1) that forms an image of light projected from the image display surface (11) on an image forming plane (30) in a space positioned on a reverse side to a side opposite to the display unit (10) of the image transmitting panel (20) to display a floating image. A shielding plate (2) is disposed at a place from the image display surface (11) of the display unit (10) to an observing place. The shielding plate (2) is comprised of a black mask (shielding member) (40) with a rectangular frame, for instance, shaped at the frame portion of the image transmitting panel (20) and shields a part or all of the light projected from a boundary (11a) of a display area of the image display surface (11) of the display unit (10).
摘要:
An image display device makes it possible to easily display a stereoscopically two-dimensional image and to improve its direction effect. A display device includes a first display for displaying a first image on a first screen, an image transmission element that is set in a light path for a display light component of the first image and that transmits the display light component of the first image so that a real image of the first image is displayed on an image forming surface positioned at a space on a side opposite to the first screen as a stray image. Further, the display device includes a. controller for controlling the first display so that at least one icon out of a plurality of icons (A-H) is displayed as a stray image disposed along a virtual path with a predetermined shape set in a real space portion including the first mentioned space.
