摘要： An image storing device for compressing an original image, storing the compressed image, and expanding the stored image while enabling a high speed searching for stored image data is provided. An encoded data classification unit can classify the encoded and compressed data into reduced data output and an unreduced data output. Both the reduced and unreduced data output are stored and a selective reading unit can address this data. The data can be decoded and expanded and an arrangement control unit can arrange a sequence to the data so that the original image is reproduced when operating upon the unreduced data and when operating upon the reduced data, only encoded and compressed corresponding to scanning lines which are subject to reduced output are decoded and expanded after being reduced in a line direction.

摘要： The invention provides a ceramic electric-discharge lamp having a pinch-sealer which is set to an end of an outer envelope and covered by a base having a pair of base pins projecting themselves into the base. The outer envelope is in vacuum, in which an arc tube composed of a square U-shaped tube is installed. Apertures of both ends of the square U-shaped illuminant are closed by ceramic discs each containing an electrode. Linear illuminant is formed in such regions where the radius of curvature of the square U-shaped arc tube greatly varies, in other words, between the curved portions.
