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 material for packaging light-sensitive materials having a light-shielding film with a thickness of 30-150 .mu.m comprised of a thermoplastic resin containing 5-25 wt % of an ethylene-propylene based rubber having a Mooney viscosity of 10-100 [ML 1+4 (100.degree.C.)] and an iodine value of 20 (I.sub.2 g/100 g EPFDM) and 1.2-10 wt % of carbon black.

Abstract: A granular carbonaceous heat insulator comprising a carbon black pellet the surface of which is coated with a carbon layer having a dense structure is disclosed. This heat insulator is prepared by adhering a binder solution to a carbon black pellet, heating the resulting coating to remove a solvent from the binder solution and, at the same time, to cure the binder, and baking the carbon black pellet coated with the cured binder in a non-oxidizing atmosphere to carbonize the cured binder. Alternatively, the heat insulator is prepared by subjecting a carbon black pellet having specific characteristics to wet granulation in the presence of a binder solution to crush the carbon black pellet and, at the same time, to granulate the crushed pellet, thereby preparing a granulated carbon black pellet, followed by removal of the solvent from the prepared pellet, curing of the binder and baking of the cured binder in the same manner as that described above.

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: An improved process for producing a photographic material in which an assembly of superposed liquid photographic layers is coated onto the surface of a moving base support in such a way that the properties of the liquid photographic layers being coated are evaluated by their dynamic surface tensions.
