摘要:
An automatic observation apparatus of sky climate conditions is provided in which an opening and closing device is designed such that a lid moves upward and downward by an elevator so as to open and close the upper portion of an observer and thus, although it snows in winter, the lid moves upward and downward while maintaining a state in which snow is accumulated on the lid, the snow does not collapse due to movement of the lid and does not fall onto a transparent cover of the observer, and thereby obstruction of a visual field of a camera by snow is prevented.

A method and an apparatus for manufacturing a nanowire are provided. The method for manufacturing a nanowire includes i) providing a source gas into a chamber, ii) controlling the temperature of a substrate received in the chamber separately from the temperature of the source gas, iii) forming a temperature gradient on the substrate, and iv) forming a nanowire having at least one growth condition selected from a group of growth speed and growth direction controlled according to the temperature gradient on the substrate.

The present invention relates to a rear projection screen (1) for allowing an observer to view an image at a front side by receiving light projected at a rear side. The rear projection screen comprises a transparent plate (3); an optical sheet (8; 8′) which is hot-pressed on a rear surface of the transparent plate (3) and includes a plurality of fine prisms (5; 5′) formed from side to side and parallel to one another to refract the light and guide the refracted light to the front side, each fine prism protruding to the rear side; a diffusion film (20) which is bonded to a front surface of the transparent plate (3) and including a transparent film (2) and diffusion layers (6) formed on front and rear surfaces of the transparent film to omnidirectionally disperse and diffuse the light refracted through the optical sheet (8; 8′); and light-shielding printed layers (4) which are formed on an upper surface of the diffusion layer (6) to be horizontally parallel to one another and face portions between the fine prisms (5; 5′) of the optical sheet (8; 8′). According to the rear projection screen of the present invention so configured, there is no reflected image on a surface on the side of an observer even under a bright environment such as the presence of sunlight, and a extremely precise color image with a high black level can be obtained. Further, a large-sized screen with less light loss can be manufactured at a low cost by first refracting light emitted from a projector through a fine prism optical sheet and then diffusing the refracted light.
