摘要： PROBLEM TO BE SOLVED: To provide a discharge lamp capable of efficiently preventing fragments from scattering when a lamp is exploded and of allowing the lamp to be high pressure and high watt. SOLUTION: In a discharge lamp provided with a reflector 2 and a front glass 3 mounted in front of the reflector 2, an air hole 4 is provided on the reflector 2 and a mesh 6 or a porous plate 5 is disposed on the air hole 4. Thereby, the heated air within the reflector 2 can be exhausted through a mesh or a through hole of the mesh 6 or the porous plate 5 so that an excessive rise of the peripheral temperature of the lamp can be prevented. Therefore, a high-pressure and high-watt discharge lamp of 150 W or above can be provided.

摘要： PROBLEM TO BE SOLVED: To restrict a change of light emitting position and light emitting shape while preventing charge of a spacer by fixing the spacer arranged between a front surface board and a back surface board having an electron source to at least one of the front surface board and the back surface board with the predetermined conductive adhesive agent. SOLUTION: A back surface board 2 loaded with an electron emitting element group 5 and a front surface board 1 loaded with an image forming member 6 are supported opposite to each other by plural spacers 4 arranged with an appropriate space. The spacer 4 is adhered for fixation to the back surface board 2 and the front surface board 1 by the adhesive agent 7 obtained by adding the metal powder having a mean grain diameter at 0.5-80 μm for distribution to the chemical reaction type inorganic adhesive agent such as alkali metal silicate at 8-80% of volume ratio so as to have conductivity. Peripheral edges of the front surface board 1 and the back surface board 2 are adhered to each other for fixation by the flit glass 8. With this structure, displacement of an electron orbit due to a change of the electric field by a charge of the spacer in the case of displaying image for a long time is eliminated, and the stabilized light emission is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a spacer which can be used relative to a high-resolution screen which works at a high voltage and, because of this, whose inter-electrode distance is large. SOLUTION: In this method for intensively manufacturing spacers also usable for a high-resolution screen having a large inter-electrode distance, a substrate is machined for obtaining a shape 30 equipped with a cross-section 32 which comprises a center core 33 and side strengthening parts 34 and in which a thickness e of the center core 33, a thickness d of the side strengthening parts 34, and a separation distance P between the side strengthening parts 34 are established so that this cross-section 32 can be inserted between pixels without interfereing with the pixels of the screen. Then, the shape-structure 30 is cut in order to obtain a portion having a predetermined length for forming a spacer.

摘要： PURPOSE:To provide a field emission cold-cathode array which can be formed by a simple and short throughput and has a uniform dimension and shape over a large area. CONSTITUTION:A substrate gap holding member 5 for holding a gap distance between an anode electrode layer 8 and the tip of an emitter 2 at a space (gap) between adjacent first substrates 11 is accumulatively formed. It can be realized by a simple method that the area of a cold-cathode array (array of emitter 2) is made large by accumulating the substrate gap holding member 5 and at the same time the gap distance between the substrate gap holding member 5 and the anode electrode layer is uniformly held over a large area.

摘要： PURPOSE:To prevent the occurrence of discharging by feeding a current through the portion where a light emitting means and its control means are brought into contact with each other. CONSTITUTION:Phosphors 20 and black lines 19 are arranged on a faceplate 12. A thin film Al is stuck on it, and stanchions 18 are formed. Stanchions 18 are formed in a train shape on a G4 electrode 15 in an electron beam control electrode group. The stanchion 18 is formed with powder glass mainly made of PbO, it is applied with the drying process each time, it is overlappingly coated 5-10 times by screen printing and baked, and a conductor film with the preset specific resistance is formed on the surface. The back side container of a back electrode, a back electrode, the electron beam control electrode group, and the faceplate 12 of the a panel thus manufactured are brought into contact with each other via stanchions 18. The withstand voltage can be stably maintained even when the electrode potential is high, and the occurrence of discharging can be prevented.

摘要： PURPOSE:To hold thermal stress generated to a minimum so as to obtain a highly reliable vacuum container for a flat display device by providing between the junction portion of an rumoring container with a plate-shaped glass and a pressure resisting member a blocking portion which protrudes from the plate- shaped glass or the rumoring container. CONSTITUTION:A blocking portion 5 protruding from a plate-shaped glass 1 or an rumoring container 2 is provided between the junction portion of the rumoring container 2 with the plate-shaped glass 1 and a pressure resisting member 3. Then an adhesive taking the form of a paste is allowed to flow from the junction portion when the process of joining the rumoring container 2 to the plate-shaped glass 1 is carried out, but the adhesive is blocked by the blocking portion 5 and will therefore not reach the inner face of the plate- shaped glass; heat stress will not be generated by junction of the pressure resisting member 3 with the plate-shaped glass 1. A highly reliable vacuum container for a plate-shaped display device is thus obtained.
