Abstract: A projection display apparatus employs a plurality of projectors 1, 2, 3 and combines images from the projectors into a large composite image on a nonplanar screen such as a concave spherical screen 10. The composite image is of high quality and high resolution and is normally visible by audience. The projectors 1, 2, 3 receive video signals through a geometric conversion unit and project and display images on the nonplanar screen 10 according to the received video signals. The geometric conversion unit transforms the field angles of images to display, according to relationships among the positions of the projectors 1, 2, 3, the positions of areas of the nonplanar screen 10 to which the projectors project images, and the position of an audience, thereby compensating distortions of images caused by the nonplanar shape of the screen 10.

Abstract: An optical attenuator which provides almost the same degree of attenuation even when the difference in wavelength of two different kinds of input optical signals is small. Another optical attenuator is provided with a dopant concentration in a technically realizable range which increases the difference in optical attenuation of two different kinds of input optical signals. Almost the same degree of attenuation may be obtained even when the difference between wavelengths is small by canceling the wavelength dependency of attenuation of the dopant by raising the refractive index of an axially central portion of the core as compared to that of the peripheral portion of the core and by taking into account the type and area of the dopant and the ratio of the difference &Dgr;2 between the refractive indexes of the cladding and the axial portion of the core and the difference &Dgr;1 between the refractive index of the cladding and the refractive index of the peripheral portion, i.e., &Dgr;1/&Dgr;2.

Abstract: When in use a highly luminous automobile discharge lamp will experience a temperature rise to about 700.degree. C. at the lamp glass surface. As such, the light-screening film formed on the lamp will also be exposed to a temperature of 700.degree. C.; the temperature of the glass surface of a lamp rises and, accordingly, that of the light-screening film formed thereon also rises. Especially with a highly luminous automobile discharge lamp, the temperature of the lamp glass surface rises to about 700.degree. C. during the lighting. Necessarily, the light-screening film on the glass surface is also exposed to a temperature of 700.degree. C. As such, a light-screening film material free of discoloration or peeling even after exposure to a temperature of 700.degree. C. has been desired. There is disclosed a light-screening film paint for lamps containing (1) at least one compound of either manganese oxide or an iron oxide compound doped with a metallic manganese and having the formula (Fe.sub.x Mn.sub.1-x).sub.
