IPC: B05B7/02
Filed: 1981-09-09
Abstract: PURPOSE:To prevent clogging despite the use of easy-to-solidify painting materials by retarding the stopping of an injecting gas from the interruption of the painting materials. CONSTITUTION:A painting gun 18 having passages communicating a supplying chamber 26 for painting materials with an injection port 27 for painting materials, shutting off the port 27 from the chamber 26 by means of a sliding pipe 28, and guiding an injection gas to the port 27 is provided. A stop valve 29 for the injection gas and a changeover valve 37 for the pipe 28 are separately provided and the stopping of the injection gas is retarded from the interruption of the painting material.

Title: Screw compressor
Inventor: AOKI MASAKAZU
IPC: F04C18/16
Filed: 1981-09-09
Abstract: PURPOSE:To reduce the internal resistance to avoid disturbance to the inflow of intake air by forming the concave having the gradient with which the radial slit increases gradually towards the discharge side from the intake side, at a part of the same phase as the intake port located in the range shifted to the intake side, on the inner peripheral wall of a casing. CONSTITUTION:A concave 15 is formed on the casing 3 which encloses male and female rotors 1 and 2. In other words, the gradient 15 with which the radial slit increases gradually towards the discharge side 15b from the intake side 15a is formed. Therefore, the air which is forced-out in the vicinity of the inner peripheral wall of the casing 3 by the centrifugal force following the revolution of a rotor, or the oil or the air heated in an oil-cooled type screw compressor flows to the discharge side where the internal resistance is small along the gradient of the concave 15 without being fed into the intake side 15a of the concave 15. Thus, the disturbance to the inflow of the air inhaled from an intake port 12 and the phenomenon that the intake air is heated can be avoided by the air forced-out by the centrifugal force due to the revolution of the rotor.

Title: Phosphor
Inventor: OSHIMA HIDENORI
IPC: H01J31/12
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a phosphor capable of coming to a substitute for a sulfide phosphor. SOLUTION: A phosphor is constituted by incorporating Pr into a composite oxide SrIn2O4 of Sr and In and accordingly, upon excitation of SrIn2O4 by an electron beam, by the excitation energy Pr is allowed to emit an emission color corresponding to the energy level, for example, a red color with a wavelength of about 610 nm. In addition, since the lattice defect present therein can be reduced by, for example, allowing Al present in the phosphor to form a solid-solution with SrIn2O4, the emission intensity is further enhanced. Since this causes deterioration of the cathode, the present phosphor does not contain S which remarkably reduces the life of a display tube and can obtain a luminance at a chromaticity equal to that of a similar red color emission phosphor of a (Zn, Cd)S:Ag, Cl phosphor in spite of a non-sulfide phosphor (oxide phosphor) free of harmful Cd.
