Patent number: 7497165Abstract: 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.Type: GrantFiled: January 20, 2005Date of Patent: March 3, 2009Assignees: National Institute of Advanced Industrial Science and Technology, Kabushiki Kaisha Kobe Seiko ShoInventors: Shuzo Fujiwara, Takehiro Matsunaga, Katsuo Kurose, Kiyoshi Asahina, Kenji Koide

Patent number: 6415658Abstract: The present invention is directed to a wear detection probe in which the deflection of a folded portion of an electric detection wire is suppressed so as to be able to cut the folded portion of the wire in a secure position. A truncated cone is formed at the edge part of a retention member, and a groove extending in a diametric direction is cut at the edge part. A supporting protrusion is formed by traversing the groove, and the electric detection wire is retained in a position in which the folded portion is securely mounted on the supporting protrusion which extends from both openings from which the electric wire extends. The wire is sandwiched by both side walls of the groove and the side walls operate as regulating walls so that when the folded portion of the electric wire begins to be exposed and contacts a brake drum, the folded portion will not be pulled out by a deflecting force in a sidewards direction.Type: GrantFiled: March 24, 2000Date of Patent: July 9, 2002Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Hitoshi Takanashi, Takehiro Matsunaga

Publication number: 20020062975Abstract: A waterproof structure applied to a wire harness has a length direction and includes a plurality of electrical cables, each of the electrical cables including a tubular coating and a core made up of plural wires. The electrical cables are respectively stripped of the tubular coating at a same given portion chosen in the length direction of the wire harness, and the cores are exposed. The exposed core wires are adhered to one another by soldering, thereby forming an aggregated external surface. The aggregated external surface is provided with a waterproofing material including an adhering material. That portion of the wire harness corresponding to the aggregated external surface is provided with a bend-prevention device. The waterproof structure of the invention can be applied to a wire harness subjected to frequent bending.Type: ApplicationFiled: November 29, 2001Publication date: May 30, 2002Applicant: SUMITOMO WIRING SYSTEMS, Ltd.Inventor: Takehiro Matsunaga
