Abstract: A blasting method of blasting an explosive device at least containing an explosive and a chemical agent in a sealed pressure vessel that prevents soot generation during blasting and improves an efficiency of decomposing the chemical agent. First, a transported chemical bomb (explosive) 100 is placed and sealed in a blasting chamber (pressure vessel) 10. The blasting chamber 10 is then brought into a reduced-pressure or vacuum state by aspiration of the air therein by using a vacuum pump 13a and oxygen is supplied through an injection port 12 into the blasting chamber 10 to a pressure of 15 to 30% of atmospheric pressure. The chemical bomb 100 is then blasted, as it is ignited by an ignition device not shown in the Figure.

Abstract: A blasting method of processing a bomb by forming an explosive layer on an outermost surface of the bomb to be processed having a casing in a particular shape and by exploding the explosive layer, wherein the explosive layer comprises a first explosive layer formed around the outermost surface of the casing and a second explosive layer formed as to surround the first explosive layer, an explosive in the second explosive layer has a higher explosion velocity than an explosive in the first explosive layer, and the second and first explosive layers are exploded at a certain time interval by igniting a particular region of the second explosive layer. The method allows low-cost blasting of bombs, by relaxing the impact of the scattering casing fragments.

Abstract: A ceramic shaped body-positioning system which can accurately position even a thin-walled ceramic honeycomb shaped body without occurring deformations, cracks and breakages of the ceramic shaped bodies and which is particularly suitable for positioning odd-shaped products is provided. A positioning system 1 for a ceramic shaped body 2 is used for positioning the ceramic shaped body 2 to accurately convey the ceramic shaped body 2 to the next step. The positioning system 1 comprises a centering table 3 for placing the ceramic shaped body 2, a plurality of chucking unit 4-1 each consisting of a chucking body 5-1 and a pair of ceramic shaped body-pushing members 5-1a and 5-1b provided in the chucking body, and a drive unit 6 for moving the chucking unit 4-1 toward/away from the ceramic shaped body 2 on the centering table 3.
