Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of a low-density composite article. SOLUTION: The method involves a step for forming a curable prepreg to a given shape and a step for curing a prepreg formed into a given shape. In the step for forming the curable prepreg into the given shape, the curable prepreg is formed into the given shape under a consolidation pressure sufficiently low so as voids to be formed in the prepreg in the curing step. In the curing step, so as evaporated material evolved from a resin composition of the prepreg by curing the curable prepreg to form voids described above, the prepreg formed into the given shape described above is cured under a curing pressure in a range from about 8.61×10 4 Pascal absolute pressure (12.5 psia) to 103.4×10 4 Pascal gauge pressure (150 psig).

PROBLEM TO BE SOLVED: To provide a nontoxic, noncorrosive and nonhygroscopic sensitized explosive that comprises an explosive precipitated onto a sensitizer and a percussion primer, a method of forming the same and a gun cartridge and other primer-containing ordnance assemblies employing the percussion primer. SOLUTION: The explosive is CL-20, PETN, RDX, HMX or mixtures thereof and the sensitizer is aluminum, titanium, zirconium, magnesium, melamine, styrene, lithium aluminum hydride or mixtures thereof. The sensitized explosive is used in the percussion primer that includes a bismuth compound and a melt binder. The bismuth compound is bismuth oxide, bismuth subnitrate, bismuth tetroxide, bismuth sulfide or mixtures thereof and the melt binder is a wax having a melting point above ambient temperature, trinitrotoluene, poly(3,3-bis(azidomethyl)oxetane), poly(3-azidomethyl-3-methyloxetane), ethyl-3,5-dinitrobenzoate or mixtures thereof.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for crystallizing ε-polymorphic phase of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.0 5,9 0 3,11 ]-dodecane (CL-20) that is useful as a propellant powder, explosive or the like. SOLUTION: In this method, the crystallization solution for CL-20 is prepared by using at least one of organic solvents and at least one of non-solvent and the solution is saturated. The saturated solution is heated up higher than about 60°C. Then, the organic solvents are vaporized and removed by applying vacuum or blowing dry gas. At this time, a sufficient amount of the non-solvent is retained to crystallize the CL-20 to the ε-polymorphic phase, and finally the crystals are filtered from the non-solvent slurry and the separated crystals are washed. The ε-polymorphic CL-20 crystals having no crystal defect and high grain density are obtained in high yield through this method. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract:
PURPOSE: To obtain facsimile equipment which can change the size and resolution of an image by changing the timing for the release of image data and the sweep of electronic beams and also repeatedly controlling lines of the image data. CONSTITUTION: When image dimensional information is given, a graphics microprocessor 10 stores image data in memory buffers 30 and 31 of a storing means 22. In a horizontal direction, it controls the ratio of releasing the image data to a CRT 50 through a timing that is supplied from a timing means 70, which includes an oscillator 72 and frequency dividers 75 and 76 and adjusts a beam intensity. It also controls a horizontal sweep ratio of the electronic beams of the CRT 50. In a vertical direction, it repeatedly controls lines of the image data. With this configuration, it can generates images with various sizes horizontally and vertically and various resolutions, and facsimile equipment that is capable of changing the size and resolution of an image is obtained.
Abstract:
PURPOSE: To inhibit electromagnetic radiation from a cathode-ray tube. CONSTITUTION: A secondary shielding enclosure 14 which surrounds CRT 18 and inhibits electromagnetic radiation is contained in a shielding-type CRT 18 display. A primary shielding enclosure 12 in the secondary shielding enclosure 14 is provided with a part 16 which is coaxial with the neck part 22 of CRT 18 for inhibiting electromagnetic radiation from CRT 18. An inner conductive layer comprising an inner aqua tag, a wire mask and fluorescence coating is included in CRT 18. The inner conductive layer is grounded through a reactive route for suppressing electromagnetic radiation. The outer shielding of the display face part of CRT 18 becomes unnecessary by the duplex shielding suppression technology.

PROBLEM TO BE SOLVED: To provide automated bias-ply material preparation device and process.SOLUTION: A material preparation device 100 includes a bias-ply assembly 105, a feedstock assembly 103 and an application head 130. The bias-ply assembly 105 is configured to pass a bias-ply backing material 146 along a first path. The feedstock assembly 103 is configured to pass a feedstock along a second path that crosses the first path at a select angle. The feedstock includes resin pre-impregnated fiber reinforced material (prepreg) having the fibers at a first orientation relative to an edge of the feedstock. The application head 130 is configured to transfer the pre-preg from the feedstock to the bias-ply backing material 146 at a location where the first path crosses the second path to form a bias-ply 158 with the fibers of the pre-preg having a second different orientation relative to an edge of the formed bias-ply 158.
