<p><P>PROBLEM TO BE SOLVED: To provide a gas pressure device, a crushing method using the gas pressure device, and a method of moving the aggregate of brittle substances capable of preventing the destruction of a device by a gas-forming agent, and recycling a pin, and not trapping a high pressure gas in the device. <P>SOLUTION: The gas pressure device includes a cylindrical body 10 having a degassing hole 14, a gas-forming section 15 having the gas-forming agent and its ignition device, and disposed at one end of the body 10, and a piston including the pin, movably disposed in the body 10, and driven by a gas pressure of the gas-forming agent so that the pin is projected from the body, a piston in the body is accelerated by the gas pressure of the gas-forming agent, the pin is driven to crush brittle substances by the pin by the kinetic energy of the piston, and the gas in the cylinder after moving the piston is released from the degassing hole 14. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
