Abstract:
Several CRT monitor assemblies, (10, 10', 10", 40, 60, 120, 170, 190), each of which incorporates a specially constructed de-ionized air generating system (12, 12', 12", 45, 70, 130, 175, 175') are adapted to produce a laminar-type flow of de-ionized air, in a predetermined direction, across the screen (26, 26', 26", 42a, 66a-69a, 126a-129a, 171a, 172a, 171a', 172a') of one or more monitors (11, 42, 66-69, 126-129, 171, 172) so as to prevent the build-up of detrimental static charge on the screens. In one particular application, wherein monitors of the computer-controlled graphics display type are employed as visual aids in circuit pack assembly and testing operations, it has been found that the excessively high values of static charge that normally tend to build-up on each monitor screen can often seriously impair, if not destroy, the operating function of many types of IC devices, particularly those of the mos-type, should they be brought into the field of such a static charge during routine handling at an assembly or test station. Advantageously, neither the de-ionized air generating system, nor the confined flow of de-ionized air produced thereby, in any way interferes with the comfort or the work functions required of an operator while utilizing such a monitor. When multiple CRT monitors are required in a given manufacturing operation of the type in question, they may advantageously be arranged in specially configured clusters, and within a common auxiliary housing (65, 122), so as to substantially reduce the floor space required, and further significantly facilitate the simplification, and reduce the cost, of the composite de-ionized air generating system employed in conjunction therewith.
