    摘要: In order to provide a phosphor for a low-voltage electron beam and a vacuum fluorescent display apparatus in which the phosphor is used, a deposition layer is formed on a surface of a main body of a phosphor shown by the following chemical formula (1), the deposition layer being a plurality of oxide layers sequentially deposited on the surface of the phosphor main body. The phosphor for a low-voltage electron beam contains no cadmium, but has exceptional high-temperature exposure characteristics, as well as prolonged service life and higher brightness.

    摘要: A high-ratio zoom lens system includes a positive first lens group, a negative second lens group, a positive third lens group, and a positive fourth lens group. Upon zooming from the short to long focal length extremities, the lens groups move while increasing the distance between the first and second lens groups, and decreasing the distance between the second and third lens groups. The first lens group includes a negative lens element having a concave surface on the image side, a positive lens element having a convex surface on the object side, and a positive lens element having a convex surface on the object side, in that order from the object side. The following conditions (1) and (2) are satisfied: 1.7

    摘要: A camera according to the present invention includes a picture-taking lens unit including a picture-taking optical system having a bending optical system which optically bends incident light and an optical finder unit including a finder optical system having a bending optical system which optically bends incident light. A pre-bending optical system and a post-bending optical system in the bending optical system of the optical finder unit are arranged adjacent to a pre-bending optical system and a post-bending optical system in the bending optical system of the picture-taking lens unit, respectively. The body of the camera is therefore decreased in size.
