Abstract: The present invention is to provide an equipment production management system, in which the electronic equipment is designed corresponding to an order from customers, which enables unified preparation from derivation of equipment corresponding to the customer conditions concerning equipment installation design, and construction associated drawing design. The system includes a terminal unit and a central control system, in which is provided a customer base order information file, design data file, a design know-how information file established by making a know-how library on the equipment installation design as input files. The central processing system includes an installation designing section corresponding to installation design for respective stages from overall layout to installation of the elementary parts.

Abstract: A cooling structure for an electronic equipment rack which comprises a plurality of shelf units stacked one upon another and arranged in a cabinet, each shelf unit accommodating a plurality of printed circuit boards and having vent holes formed on upper and lower surfaces thereof respectively. A fan unit having at least one fan is disposed on top of each shelf unit to constitute a separate cooling block. The fan unit of each cooling block generates a cooling wind which is passed linearly through the shelf unit from the bottom to the top of the shelf unit as well as introducing atmosphere through vent holes formed on side face portions of each fan unit to mix the atmosphere with the cooling wind. As a result, the flow rate of the cooling wind will be gradually increased as the cooling wind proceeds to the upper cooling blocks due to the addition of an upward blowing force caused by the fans of the fan units.

Abstract: Electronic communication device shelf units for packing therein printed circuit boards wherein the shelf units are to be put one upon another in a cabinet, wherein each said shelf unit comprises hollow side plates provided with air inlet openings on their outer faces, and a top plate which is connected to the side plates and having a V-shaped heat diffusion plate defining thereon an air introduction space; the side plates are provided, on their inner faces, with openings communicating with the air introduction space, such that hot air diffusion for each shelf unit is independent of the other shelf units.

Abstract: This application discloses a frame unit for communication and other electronic devices including a pair of parallel side plates interconnected by upper and lower guide rails extending between and perpendicular to the side plates, and a plurality of guide members which are secured to the guide rails and which are adapted to guide therealong printed boards on which circuit elements of an electronic device are provided. The application also discloses a frame device composed of a number of such frame units.

Abstract: A mounting apparatus for communication signals exchange equipment is described. The apparatus includes supporting poles, each of which is erected close to each of the components of the communication signals exchange equipment, and further includes frameworks which are assembled horizontally above said supporting poles and rigidly fixed to the top ends of said supporting poles. The supporting poles and frameworks are provided both for mechanically supporting said components and for distributing a large number of communication signals cables between one component and other components. The construction of both the supporting poles and frameworks is completed by the time said components are located at their desired positions.
