Abstract: A broadband line source that is directional, rugged, compact, spatially and temporally uniform, stable, without the need for warmup, and relatively easy to implement. The source can be in single-color or multi-color, and it can be used, for example, in a scanner. In one embodiment, the line source includes a first thin-film electroluminescent stack with at least a bottom electrode, a top electrode, and a first active film between the two electrodes. The active film generates radiation in an area that has a width and a length, with the length being larger than the width. The length of the area sets the length of the line radiation, which is substantially homogenous along the line. In another embodiment, three of such stacks are encapsulated through thin-film processes by a cap, which sits on a substrate. The cap has one side surface that is more transmissive to radiation. The generated radiation is directed by the cap to be emitted at the more transmissive side surface to produce a single-color or a multi-color line source.

Abstract: A liquid cooling type projector is provided with greater flexibility to meet different screen sizes of a projection television and, thus, contributes to the reduction of production cost. The projector has a cylindrical frame containing a projection lens unit mounted by a liquid-tight member thereto and coupled at a rear end to a CRT in liquid-tight arrangement such that a liquid-sealing space is established between the projection lens and the CRT. In particular, the projection lens unit is arranged so as to be movable with respect to the frame along its optical axis. Also, the liquid-tight member is arranged to maintain the liquid-tight condition regardless of the position of the projection lens unit relative to the frame. Thus, the projection lens unit can arbitrarily be displaced towards and away from the CRT, increasing a focusing range. Accordingly, the projector will successfully be matched to different sizes of projection screens contributing to the reduction of the production cost of projection televisions.

Abstract: An electron beam current modulator is provided between a cathode and a laser screen of a cathode-ray tube and has at least three deflecting plates positioned around, and symmetrically with respect to an optical axis of the cathode-ray tube and a diaphragm having an aperture of a regular shape. An electromagnetic control system is provided between the cathode and deflecting plates. A pickup senses position of the electron beam and produces a signal in case of an offset of the electron beam with respect to the optical axis. A video signal source is connected to a carrier generator having an output connected to an input of a phase shifter. The phase shifter has its outputs connected to the deflecting plates to rotate the cross-section of the electron beam in a plane drawn perpendicularly with respect to the optical axis. The apparatus has a control unit having an input connected to the pickup and an output connected to the electromagnetic control system.

Abstract: A projection cathode ray tube (CRT) includes a multilayered interference film interposed between a face plate pane and luminescent material layer. This multilayered interference film is composed of alternately superimposed of high refractive index material layers and low refractive index material layers, and the number of layers to be superimposed is four or five. By using a multilayered interference film of only four or five layers, the interference layer is not subject to cracks or film separation occurring during heat processing, due to the difference in thermal expansion coefficients between high and low refractive index material. Further, there still remains enough layers to produce a display highly improved in brightness in the direction of the normal of the face plate pane of the CRT.
