摘要： A thin conductive film, which excels in film strength, weather resistance, transparency, and electric field shielding effect, is formed on a glass substrate at a low temperature as a multilayer film consisting of two layers of an ITO dispersed silicate layer and an overcoat silicate layer, or three or more layers, of which at least two layers are an ITO dispersed silicate layer and a high-conductivity oxide dispersed silicate layer, and the topmost layer is an overcoat silicate layer.
The ITO dispersed silicate layer is essentially consists of ultra fine particles of indium tin oxide and a silicate-based glass matrix, and the high-conductivity oxide dispersed silicate layer consists of one or more among ultra fine particles selected from a group of ruthenium dioxide, rhenium trioxide, iridium dioxide, rhodium dioxide and irridium-based pyrochlore and a silicate-based glass matrix.-

摘要： Electrical apparatus comprises antenna means (200) for directing towards an electric field source to detect the electric field (E) to be reduced. The antenna means (200) is connected to amplifier means (210) for generating an output signal in response to an input signal from the antenna means (200). The output signal is in anti-phase to the input signal. Radiator means (140) is connected to the amplifier means (210) for radiating an cancelling electric field (E') in anti-phase to the electric field (E) from the source (100) in response to the output signal from the amplifier (210) to at least partially cancel reduce the electric field from the source (100). The antenna means (200), when directed towards the source (100), is positioned relative to the radiator means (140) and the source (100) to detect both the cancelling electric field (E') from the radiator means (140) and the electric field (E) from the source (100). The input signal produced by the antenna means (200) is thus derived from the sum of the electric field (E) to be reduced from the source (100) and the cancelling electric field (E') from the radiator (140).

摘要： A color cathode-ray tube (CRT) has a rectangular faceplate panel (12) with a major axis (A-A) and a minor axis (B-B). A viewing screen (13) is disposed on an internal surface of the panel. The panel is sealed to a funnel (14) along an edge (16) of a sidewall of the panel. A color selection electrode assembly (22) is spaced from the screen and attached to the sidewall of the panel. An internal magnetic shield (218) has a substantially rectangular base (219), with four corners (240-246), which is secured to the color selection electrode assembly, and a flange (230) circumscribing an aperture (231). A substantially continuous shield sidewall (227) extends between the base and the flange. The shield sidewall extends backward along an inner surface of the funnel. The internal magnetic shield is improved by at least two pairs of strengthening ribs (234,236) which are formed in opposite sides of the shield. The ribs are substantially parallel to the minor axis of the panel and in proximity to the flange of the shield. At least one (236) of each pair of ribs extends around two adjacent corners of the shield sidewall.

摘要： A cathode ray tube (CRT) has a deflection yoke (22) and an internal conductive layer (20). A conductive guard screen (24) is positioned between the deflection yoke (22) and the internal conductive layer (20) for reducing capacitative coupling between them. This reduces AC electric fields emitted from the viewing surface of the CRT. The guard screen comprises a flexible circuit wrapped around the outside of the CRT, the circuit having interdigitated sets of conductive tracks or fingers.

摘要： In a flat cathode ray display tube in which an electron beam (30) is directed firstly in a rear region (24) parallel to a faceplate (14) carrying a phosphor screen (16) and then reversed to travel in the opposite direction in a front region (22) before being deflected towards, and raster scanning over, the screen, a magnetic shield (60) is provided in the rear region to shield the beam from magnetic fields entering through the faceplate over a certain of its path length in that region to reduce raster shift effects caused by such fields. This is especially useful where the electron beam in the front and rear regions is a low-energy beam, rendering it particularly susceptible to influence by magnetic fields, this beam being supplied to an electron multiplier (44) overlying the screen.
