    摘要: A miniature x-ray tube has an anode assembly capable of transmitting x-rays through the anode and over a wide angular range. The anode is in the shape of a cone or truncated cone with an axis on the x-ray tube frame axis, formed of low-Z material with high thermal conductivity for heat dissipation. A target material on the anode body is in a thin layer, which may be approximately 0.5 to 5 microns thick. In one embodiment a tube evacuation exhaust port at the tail end of the anode assembly forms a cavity for a getter, with a pinched-off tubulation at the end of the cavity.

    摘要: A miniature x-ray tube capable of intra vascular use, has a micro cathode preferably formed by MEMS techniques. The very fine wire of the cathode filament is formed on a semiconductor base and draws a current sufficiently low that lead wires in a cathode heater circuit, passing through a probe line connected to the x-ray tube, can be very small wires, which helps maintain sufficient dielectric spacing in the high voltage circuit handled by the same probe line. In a preferred embodiment the probe line comprises a glass fiber, held at a small diameter to allow flexibility for navigating small-radius turns within the vessels. In a preferred embodiment the fiber is overcoated with a high-dielectric polymer to significantly increase the dielectric strength of the overall cable, without adding significantly to stiffness. The high voltage ground conductor is a coaxial sheath on the outside of the polymer. Exterior to the ground conductor is a further flexible layer having paths for coolant.

    摘要: A grid which controls electron flow, placed between a field emitter cathode and fluorescent anode in a flat cathode ray tube improves focusing, and reduces the switching voltage necessary to stop electron flow. The focusing capabilities of the grid enable increased distance between the cathode and anode, permitting higher anode voltage and use of more efficient phosphors. With the grid, electron flow on/off addressing can be done with drivers operating at less than 30 V, thereby reducing capacitive power loss over prior art addressable arrays and permitting use of inexpensive CMOS control circuitry. The grid's switching capabilities enable the use of a simplified field emitter cathode structure with resistive gate films which increase emitter reliability, emitter life, and, for cathode ray tube displays, the uniformity of the display.

    摘要: A flat screen cathode ray tube is self supporting of a phosphor coated glass face place in that a multiplicity of support points or lines of support extend from an addressing grid structure to contact the inside surface of the face plate between pixels. A cathode or back plate is similarly supported against the addressing structure. The addressing structure itself is formed of a series of ceramic plates or layers, assembled in an unfired state wherein the ceramic and/or glass materials are held together with a plastic binder and are flexible and easily handled. A matrix of very small holes is formed in each plate, one hole for each of the R, G and B components of each pixel in a color display. The holes, in registry in the laminated addressing grid structure, each have adjacent conductive metal traces deposited on the ceramic surfaces, and these traces, connected by vias between layers, form a grid of connectors which permit the addressing of each pixel in a sequence in accordance with an input signal such as a video signal. Addressing traces preferably extend between ceramic layers under the hermetic seal of the CRT so that the seal does not directly cross any addressing traces.

    摘要: A method and apparatus for controlling the stripping of paint and the like from a substrate is disclosed. Embodiments for controlling the stripping of paint and the like by pulses of high intensity radiant energy are described. The control is accomplished by illuminating the area of the paint and the like which is to be stripped and subjecting the light reflected therefrom to spatial spectral dispersion. The spatial spectral dispersion is sensed and an electronic signal representative thereof is generated. The generated electronic signal is compared to a pre-recorded electronic signal representative of the spatial spectral dispersion of light reflected from the paint and the like which is to be stripped before each pulse of high intensity radiant energy and the pulse is applied only upon such comparison resulting in a substantial match. Methods and means for normalization of the sensed spatial spectral dispersion and for utilizing mismatch comparisons are disclosed.
