Abstract: HIGH PRESSURE SODIUM VAPOR DISCHARGE LAMP The specification discloses a high pressure sodium vapor discharge lamp comprising an alumina tube envelope containing sodium, an inert starting gas, a mercury or cadmium buffer gas source and a pair of discharge electrodes. The inner diameter d in mm of the tubular envelope and the average potential gradient E in volt/cm has the following relationship: E ? 37.7-2.05d. The lamp further comprises a radiation suppressing means at least partially surrounding the tube envelope for selectively, and at least partially, absorbing red radiation having wavelengths longer than 620 nm. The lamp achieves a higher color temperature and a higher general color rendering index than conventional lamps of this type without an undesirable increase in the tube voltage, and is suitable for highly efficient indoor illumination.

Abstract: A plurality of scanning electrodes and a plurality of sustaining electrodes parallel to each other are located on an inner face of a first glass substrate. Each of the scanning electrodes and each of the sustaining electrodes form a pair. A dielectric layer and a protection layer are formed on the first glass substrate in this order, covering the electrodes. A plurality of data electrodes perpendicular to the scanning electrodes and the sustaining electrodes are located on an inner face of a second glass substrate which is located opposed to the first glass substrate with a discharge space interposed therebetween. In an AC-type PDP having such a structure, at least one of the plurality of scanning electrodes and the plurality of sustaining electrodes are divided into a plurality of groups, and pulses having different phases are applied to the electrodes in different groups, thereby causing sustaining discharge. The scanning electrodes and the sustaining electrodes may be comb-like with teeth. The comb-like scanning electrodes and the comb-like sustaining electrodes are opposed to each other with a small gap interposed therebetween in the manner that the teeth thereof are in engagement with each other. In such a case, the data electrodes are located opposed to and in a longitudinal direction of the teeth of the scanning electrodes.

Abstract: PURPOSE:To simplify the panel structure of a display apparatus, lessen the electric power consumption, and extend the life of the apparatus by forming a discharge hole to expose at least a part of a first electrode to a dielectric layer in a discharge cell. CONSTITUTION:A group of first electrodes 11 and a group of starting electrodes 12 formed on an insulating substrate 10 are coated with a dielectric layer 13 and a group of stripe-like second electrodes 15 are formed on a transparent glass substrate 14. The group of the electrodes 15 are kept from the group of the electrodes 11 and the group of the electrodes 12 at prescribed gap and so set as to face to these groups at right angles. Discharge cells 17 are positioned at the position facing to the group of the electrodes 11 and the group of the electrodes 15 at right angles and are composed of walls 16 which are arranged to form a lattice and discharge holes 18 are so formed as to expose at least a part of the electrodes 11 to the layer 13 in the cells 17. Furthermore, auxiliary discharge cells 19 are set at the position facing to the group of the electrodes 15 at right angles and slits 16a are formed in the walls 16 of neighboring cells 17 for the electrodes 12 and the auxiliary cells 19 are communicated with the cells 17. As a result, the resulting panel has a simplified structure, electric power consumption is lowered and the action life can be extended.

Abstract: PURPOSE:To control discharge current as well as to reduce the electric power consumption of a driving device and to allow POG (package on glass) while eliminating the need for an anode resistor of a high resistance value for limiting the discharge current by providing a constant current output circuit which compares the output of a logical circuit for display with a reference power source output. CONSTITUTION:The constant current output circuit 19 and the anode resistor 20 are connected to the electric lines from the logical circuit 9 for display to the respective anodes 4a, 4b... of a discharge tube for display. The constant current output circuit 19 has the function to form the constant current by as much as to control the discharge current. The anode resistor 20 is merely used for protecting the constant current output circuit 19 and is, therefore, required to be much smaller than the conventional anode resistor. The electric power consumption by the anode resistor is drastically reduced in this way and the direct packaging of integrated circuit elements for driving, etc., on a flat glass plate is possible. The POG is thus possible.

Abstract: PURPOSE:To check occuring of cathode glow discharge concentrically on a small region of a cathode surface by providing a transducent anode to be connected with a positive potential terminal of a DC power source in opposition to a group of cathode elementary pieces through a discharge space. CONSTITUTION:A glow discharge tube for background lighting starts discharge by the properly impressed DC voltage between anode 5 and a back electrode 6 to generate cathode glow on the group of cathode elementary pieces and when the cahode elementary piece 8b, for instance, of the group of cathode elementary pieces starts discharge prior to others, voltage drop due to internal resistance rb between the cathode elementary piece 8b and the back electrode 6 becomes selectively big. Accordingly, the potential of the cathode elementary piece 8b tends to be biased to the positive side than that of the other cathode elementary pieces 8a, 8b... and the cathode glow having been generating on the surface of the cathode elementary piece 8b extends to the side of the cathode elementary pieces 8a, 8c... to obtain uniform cathode glow luminescence with no unevenness and missing on the whole surfaces of the group of cathode elementary pieces.
