摘要： PURPOSE:To obtain light with very high chromatic pureness as original color light by furnishing a filter incl. neodymium oxide on the light takeout side. CONSTITUTION:On the inside of a neodymium oxide glass filter plates 7 arranged oppositely on the display side electrode 6 side at a certain spacing, a stripped red filter 8r and green filter 8g are furnished alternately in the facial direction in stripe pattern at the installation pitch corresponding to each stripe of the display side electrode 6. Similar light emission display may be obtained when a simple glass plate is used in lieu of neodymium oxide and instead the filters 8r, 8g contain neodymium oxide powder. It is also practicable that a neodymium oxide glass filter plate is used as substitute for a base board 1 and layers of elements are formed on this filter plate.

摘要： The compsn., based on a water-soluble polymer (I) which becomes insoluble when exposed to light in the presence of a Cr (VI) cpd. (II), contains 25-400, pref. 50-200 pts. wt. water-soluble monomer (III), forming a polymer which is insoluble or scarcely soluble in water, per 100 pts. (I) and 1-30 pts. (II). Used for the prodn. of printing plates. The speed and adhesion of the resin to the substrate are improved. Examples of materials are, for (I): gelatin, polyvinyl alcohol, polyvinylbutyral, poly(vinyl alcohol-CH2: CHCONH2), and polyacrylamide. As (II) (NH4)2Cr2O7, Na2Cr2O7, K2Cr2O7 or (NH4)2CrO4 may be used. An example of (III) is CH2:CR. COO(CH2)nOR' (in which R is H or Me; R' is H, Me, Et or Bu and n = 2 or R' is H and n = 3). The addn. of 20,40 or 60% polyethylene glycol 600 dimethacrylate to a compsn. based on PVA and 5% (NH4)2Cr2O7 reduced the min. exposure needed from 2.51 to 2.42, 1.65 or 0.95 klx-min respectively.

摘要： PURPOSE:To obtain a high-quality thin film of a luminescent material to which a donor-acceptor pair luminescence center is homogeneously added by supplying the raw material of the donor-acceptor pair which forms a luminescence center from an independent evaporation source which differs from the raw material to a reaction system. CONSTITUTION:In a method for forming a thin film having a luminescence center and made of the material represented by the formula by reacting or depositing the desired raw material under reduced pressure, the raw material of a donor-acceptor pair which forms the luminescence center is supplied from an independent evaporation source which differs from the raw material represented by the formula to a reaction system to form the intended thin film of a luminescent material. The thin film is one which comprises the donor-acceptor pair as the luminescence center added to the material represented by the formula and emits light based on the donor-acceptor pair when excited by light. This thin film can be applied to a thin-film electroluminescent element and, particularly, ZnS:Ag, Cl or Zn:Ag, Al which is blue- emitting material realizes highly luminant and high-purity blue electroluminescence which has been believed to be difficult to realize.

摘要： PURPOSE:To obtain a cathode ray tube using a blue light-emitting fluorescencer capable of improving the luminous color tone and electric current coefficient. CONSTITUTION:A silver-activated cubic zinc sulfide fluorescencer is mixed with a silver-activated hexagonal zinc sulfide fluorescencer at a suitable ratio. The resultant fluorescencer is then used to prepare a cathode ray tube. Both color tone and electric current efficiency of the cathode ray tube can be improved by providing the cathode ray tube with the blue fluorescencer capable of emitting deep blue light as a fluorescent film. The obtained cathode ray tube can be used to realize an improvement in the range in which the color tone is reproduced and the resolution of a color TV image receptor.

摘要： PURPOSE:To form a coated layer with pulverulent body at a part where tackiness is produced by light of a sensitive paint film in a short time, by setting up a potential difference between a base body coated with a film carrying tackiness or an ordinary film and an electrode opposed to the base body, while having the pulverulent body and the film contacted with each other after giving a charge to the pulverulent body from the electrode. CONSTITUTION:A luminous tacky sensitive material 2 is applied to a glass panel 1, and a strapy figure is exposed through a shadow mask. Next, a blue luminescent zinc sulfide phosphor 3, etc., stuck with a cobalt blue pigment and the like is given from a powder feed nozzle 4 adjacent to the lower part of the panel. Furthermore, a wire net 5 is set up in an interspace between a luminous tacky film and the powder feed nozzle 4 and then a voltage of -10kV, for example, is impressed on the luminous tacky film grounded. With this, a coated layer with pulverulent body can be formed up at a part where tackiness is produced by light of the sensitive paint film in a short time.
