Abstract: In a server cooling device having a cold zone and a hot zone, a flow of cold air is determined depending on an air conditioner disposed in the hot zone and a size of a casing. A server cooling system is provided in which a chamber is substantially divided into two parts with a cold aisle formed in one part and a hot aisle formed in the other part, and a server rack is disposed on a boundary between the cold aisle and the hot aisle. The server cooling system includes: an air conditioner provided on the hot aisle side; a circulation path disposed so as to extend from the air conditioner to the cold aisle; and a shield provided on the boundary excluding the server rack. The shield is provided with a gallery capable of venting from the cold aisle to the hot aisle.

Abstract: A digital photograph processing system capable of facilitating editing operation after photographing and outputting a photograph of defined dimensions in a short period of time. A cut range of picture data which permits a distance between two points of picture data required to be realized as an actual predetermined dimension is operated by merely inputting the two points by operation, resulting in a photograph being outputted. This highly facilitates designation of a cut position as compared with the conventional image or picture processing.

Abstract: A light-amount correction dynamic range expanding device that can increase the number of exposure gray levels without increasing the memory capacity of the storage section for light-amount correction. Input data is formed of (n+k) bits to increase exposure gray-scale level. A first look-up table stores the output densities to the number of exposure gray levels for photosensitive substances classified by photosensitivity. Of (n+k) bits output from the first table, a first selector selectively outputs only effective n bits to a second table 2 to use m bits needed for a photosensitive substance. The second look-up table stores brightness information to correct variations in brightness between luminous dots of a print head, with a memory capacity of n bits. A FIFO memory temporarily stores the brightness information. A selector 2 again converts the output from the FIFO memory into a (n+k)-bit form and ten it to a gray-scale control means.

Abstract: A flat type display device capable of being substantially thinned and carrying out display of very high definition on a large image plane. A plurality of electron streams emitted from a cathode arranged at one end of a airtight casing in a manner to be deviated from a phosphor screen section are guided and turned toward the phosphor screen section. Then, the electron streams are selected and controlled by an address electrode section, resulting in formation of an electron beam, which is then accelerated by an accelerating electrode section and impinged on the phosphor screen section for desired luminous display.
