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： PURPOSE:To improve heat radiation efficiency at a semiconductor laser edge side and to prevent heat generation due to optical absorption at the edge side by forming ZnxSe1-x(0 direction. Then Zn is diffused in the diffusion holes and a current path which reaches the layer 4 through the layer 5 is formed on a trapezoid groove. Then p side and n side electrodes 6, 7 are formed and a laser chip having a desired length of a resonator is constituted. The chip is put in low pressure MOCVD equipment then a ZnSSE film 8 of a desired thickness which is relevant to half of the laser oscillation wavelength is formed on both the end sides of the resonator of the chip at a predetermined temperature, thus increasing the heat radiation effect of the edge side.

摘要： PURPOSE:To efficiently lead a gas introduced into a vacuum chamber on a substrate and speed up a crystal growth rate, by providing a reflecting plate having a specific position and direction below blowout holes provided at the tip of gas-introducing part of a gas cell. CONSTITUTION:A substrate 43 attached to a holder 42 in a vacuum vessel 41 is arranged downward and a gas cell is in the position opposite to the substrate 43. There is a gas blowout part 45 at the tip of a gas introducing pipe 44 and a blowout holes 46 and reflecting plate 47 are arranged therein. A raw material gas introduced from a gas introducing bomb 48 to direction of the arrow 49 enters the blowout part 45 while repeatedly reflecting on the wall face. The gas molecule collides with the reflecting plate 47 in the blowout part and is reflected thereby and passes through the blowout holes 46 and goes forward the substrate 43. Only gas molecule whose spread is regulated by the blowout holes 46 is permitted to go forward the direction of the substrate 43. When the gas molecule reflected with the reflecting plate 47 is reflected to opposite direction by a plate 50 in which the blowout holes are formed, the gas molecule is repeatedly reflected in the blowout part 45 until the molecule is passed through the blowout holes 46.

摘要： PURPOSE:To improve brightness of the captioned tube by forming a fluorescent material layer being a fluorescent screen of said tube by adding, into said fluorescent material, white-colored fine powder of Al2O3 or In2O3 having better thermal conductivity than said fluorescent material. CONSTITUTION:Upon forming a fluorescent screen of a projection type cathode- ray tube, white-colored fine powder of Al2O3 or In2O3 having better thermal conductivity than a fluorescent material to be applied is added into said fluorescent material Y2O3S:Tb in a weight ratio of 1-5%, and applied on the fluorescent screen to provide a fluorescent material layer. Accordingly, white-colored fine powder is added in a specific amount, whereby a coefficient of utilization of an electron beam can be improved, while fine powder having good thermal conductivity is added in a specific amount, whereby surface temperature of the fluorescent material layer can be reduced. Thus, brightness of the present tube can be improved by about 9% as compared with prior ones.

摘要： PURPOSE:To obtain a Eu -activated rare earth elements oxysulfide fluorescent substance with higher luminance than that of a conventional one by using a flux contg. at least sodium pyrophosphate to raw materials for synthesis. CONSTITUTION:In synthesis of a fluorescent substance of formulaI, oxide of A such as Y2O3, oxide of B such as Tb contained in the above Y2O3, oxide of Eu such as Eu2O3, and S are used as raw materials, and they are blended with Na4P2O7 as a flux and calcined. At this time, the Na4P2O7 may be used together with a conventional alkali metal phosphate such as K3PO4. The amt. of the Na4P2O7 added is more than 0.005mol, practically more than 0.05mol to 1mol of the rare earth elements oxide. The luminance of the resulting fluorescent substance can be enhanced by 1-3% compared to a conventional one.

摘要： PURPOSE:To lessen the degrading of electron beam diameter and improve image quality of projection type CRT by using registration technique of a phosphor film and a light scattering preventive structure. CONSTITUTION:In the case the width of a phosphor film strip, the width of a void, the diameter of a light emitting spot, and the diameter of electron beam are defined respectively 11, 12, 13, and 14 in the figure, even if the phosphor plane is resolved at high resolution, the improvement of light emitting spot diameter 13 is not remarkable. Based on the experiment result, to suppress the deterioration ratio of the light emitting spot diameter 13 to 50%, the width of the phosphor film strip 11 is needed to be 1/2 or less than the electron beam diameter 14. Meanwhile, since strain due to optical system is generated, the image should be strained analogously for correction, and to eliminate the optical strain in the periphery part of the image the width 11 of the phosphor film stripe is needed to be 1/5 or less than the electron beam diameter 14. This problem is also solved by making the registration (partitioning) structure of the phosphor film be a strip structure. Since black stripes are formed in a reticular screen of projection plane, the resolution in the perpendicular direction is kept by setting stripes at right angle to the former stripes. To make the perpendicular resolution high, dot shape is preferable.

摘要： PURPOSE:To obtain a fluorescent thin film which is easy to maintain the instrument and suitable for an electroluminescent display by using a mixture of rare earth oxides and sulfides as a sputtering target. CONSTITUTION:A mixture of Ln2O3 and Ln2S3 (Ln is Gd, La, Y) is used as target to effect sputtering in an inert gas such as Ar to form the subject Ln2O2S thin film. At least one of rare earth elements among Pr, Nd, Sm, En, Tb, Dy, Ho, Er, Tm and Yb may be added to the target as an activator in the form of sulfide, oxide or halide. Or it can be previously added to the Ln2O3 and/or Ln2S3. The molar ratio of Ln2S3/Ln2O3 mixture suitably ranges from 2 to 6.
