摘要： A plasma pinch extreme ultraviolet source using lithium vapor requires surrounding surfaces that are heated or cooled in order to evaporate the desired quantity of lithium, typically setting the vapor pressure of lithium at a pressure of a few torr. Two distinct surfaces within the whole set are designated as the electrodes that emit and receive the high current of the plasma pinch. A method is described whereby the temperature of these designated electrode surfaces is manipulated in order to condense lithium and provide a liquid metal protective layer to absorb both plasma and extreme ultraviolet heat thereby controlling electrode erosion. A further method is described that provides a protective flow of liquid lithium exactly on the axis of the pair of discharge electrodes.

摘要： A cathode assembly (27) includes a thermally conductive insulating substrate (21) having a pair of opposing surfaces. A cathode base member (24) is formed on one surface of the insulating substrate, and a heating member (25) for heating the cathode base member is formed on the other surface of the insulating substrate. A heater electrode terminal (26) is fixed to the electrode of the heating member through a metal layer (26a). A first grid (30) is fixed to the insulating substrate to oppose the cathode base member through a predetermined space.

摘要： A cathode ray tube apparatus that can reduce the leakage extraneous electric field with low cost. The cathode ray tube apparatus comprises a front panel, a glass bulb having a funnel part including an anode terminal at the outer surface thereof and a neck part including an electron gun, a deflection apparatus comprising a horizontal deflection coil on the outer surface of the funnel part and the neck part of the glass bulb, a flyback transformer connected to the anode terminal of the funnel part via a first lead wire having an insulating coating, and a leakage extraneous electric field controller installed on the first lead wire. The controller reduces the leakage of the extraneous electric field from the first lead wire. It is preferable that the leakage extraneous electric field controller comprises a negative pulse generator generating negative pulses having a reverse polarity and a synchronized period with respect to the horizontal deflection voltage signal of the horizontal deflection coil, a conductor at least partially surrounding the insulation coated first lead wire, and a second lead wire connecting the negative pulse generator and the conductor.

摘要： A low-power cathode can be obtained by arranging it on a substrate (1), preferably of silicon, which is entirely or partly removed at the location of the emissive structure (11) by means of, for example, anisotropic etching. Because of its low power, the cathode is particularly suitable for multi-beam applications.

摘要： In order to bring a high power vacuum tube to full power in a few seconds, it is necessary to heat the cathode quickly to 1100.degree. C. In large tubes, prior art structures cannot be simply enlarged. A novel cathode structure in which the heater element is anisotropic pyrolytic graphite coated with anisotropic pyrolytic boron nitride for insulation and then sintered to the cathode avoids these problems.

摘要： A fluoroescent display panel has at least one indirectly heated cathode which is easy to manufacture, at a low cost. The cathode produces a uniformly lit display across the entire read out. An indirectly heated cathode comprises a metal sleeve having a layer of electron emissive material. A heating wire passes through the metal sleeve. The metal sleeve and the heating wire are electrically isolated from each other by an insulative layer on the heating wire, except at one portion where the metal sleeve and the heating wire are mechanically and electrically connected to each other.

摘要： A hollow cathode electrode, particularly useful in fluorescent lamps, comprises an outer metal sleeve, an inner metal sleeve disposed within the outer sleeve and an emissive mix disposed on the inner sleeve. In one embodiment, the inner sleeve is a folded cylinder having a square cross section disposed within a circular cylinder. The object of the present invention is to prevent heat loss from the inner sleeve and to minimize sputtering. The electrode of the present invention may also include a third exterior sleeve surrounding but not contacting the interior sleeve or sleeves.

摘要： A low mass insulated heater that can be bonded with low thermal drop to an object to be heated consists of a planar arrangement of a heater wire which, after being covered with a thin coating of insulation, is coated with material that is sintered or alloyed to form a metallic sheath. The sheath is brazed directly to a member to be heated to form an integrally bonded structure in which the composite materials all have similar thermal expansion characteristics.
