Patent number: 9032799Abstract: A nondestructive inspection apparatus according to the present invention has a transmission-side probe configured to emit a first ultrasonic wave toward a test-target fluid, a plate through which a Lamb wave generated by the first ultrasonic wave is propagated when the first ultrasonic wave is propagated, and a reception-side probe configured to measure intensity of a second ultrasonic wave which is emitted from the plate and propagates through the test-target fluid. At this time, the nondestructive inspection apparatus can inspect the test-target fluid without bringing the transmission-side probe configured to emit the first ultrasonic wave and the reception-side probe configured to measure the second ultrasonic wave into contact with the test-target fluid.Type: GrantFiled: November 10, 2009Date of Patent: May 19, 2015Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Hidetaka Hattori, Hideki Horizono, Masayuki Kanemasu, Shigeyuki Matsubara, Kunihiko Shinoda, Hirotoshi Hujigaki, Susumu Ryuuou

Patent number: 8225668Abstract: An ultrasonic wave propagating method capable of propagating plate waves between a probe and a test piece despite variations in the thickness or the surface angle of a test piece, and an ultrasonic propagating device and an ultrasonic testing device using this method. Ultrasonic waves are propagated between a probe (20) for transmitting or receiving ultrasonic waves and a test piece (100) for propagating plate waves. When propagating ultrasonic waves, a probe that can set an ultrasonic wave incident angle from the probe (20) to the test piece (100) and/or an ultrasonic wave receivable angle from the test piece to the probe in a plurality of states is used. A focal point type probe may be used as the above probe (20).Type: GrantFiled: June 30, 2006Date of Patent: July 24, 2012Assignees: Independent Administrative Institution Japan Aerospace Exploration Agency, Non-Destructive Inspection Company LimitedInventors: Hideki Yabushita, Tatsuyuki Nagai, Shigeyuki Matsubara, Norio Nemoto, Hiroshi Miyamoto

Patent number: 8024975Abstract: An ultrasonic wave is sent from a transmission element to a test element to produce a plate wave in the test element, and the plate wave propagating through the test element is received by a reception element to thereby test the test element on the propagation route of the plate wave. The other probe that is the other reception element or transmission element is disposed between the transmission element and the reception element. A probe holding mechanism that has support legs contacting the surface of the test element and keeps constant an angle of the other probe with respect to the surface of the test element is allowed to support the other probe. And, the other probe is allowed to cross over in non-contact the propagation route of the plate wave extending from the transmission element to the reception element by means of support legs.Type: GrantFiled: June 30, 2006Date of Patent: September 27, 2011Assignees: Independent Administrative Institution Japan Aerospace Exploration Agency, Non-Destructive Inspection Company LimitedInventors: Hideki Yabushita, Tatsuyuki Nagai, Shigeyuki Matsubara, Norio Nemoto, Hiroshi Miyamoto

Patent number: 7721606Abstract: An ultrasonic test method for detecting a defective portion more precisely in a noncontact reflection way, and ultrasonic test instrument used for the method. An ultrasonic wave is transmitted from a transmitter (20 (21)) provided on one side of an object under test, and the reflected wave is received by a receiver (30 (31)) provided on the same side. The ultrasonic wave is transmitted/received through an air layer between the transmitter and the object (100) under test and between the receiver and the object (100). The relative positions of the transmitter (20), the receiver (30), and the object (100) are so determined that the air propagation time ta of the air path (RA) between the transmitter and the receiver is longer than the propagation time tb of the reflected wave in the reflection path (RB). The propagation of the ultrasonic wave through the solid body between the transmitter and the receiver is blocked.Type: GrantFiled: November 11, 2005Date of Patent: May 25, 2010Assignee: Independent Administrative Institution Japan Aerospace Exploration AgencyInventors: Makoto Shirai, Hiroshi Miyamoto, Shigeyuki Matsubara

Publication number: 20080302188Abstract: A ultrasonic testing method capable of carrying out a test of high degree of freedom where a degree of freedom of arranging a transmission element and a reception element is high and the scope of an object of testing is not likely to be limited, and a ultrasonic testing device using this. An ultrasonic wave is sent from a transmission element (20) to a test element (100) to produce a plate wave in the test element, and the plate wave propagating through the test element is received by a reception element (30) to thereby test the test element on the propagation route of the plate wave. The other probe that is the other reception element (20) or transmission element (30) is disposed between the transmission element (20) and the reception element (30). A probe holding mechanism (40) that has support legs (46) contacting the surface of the test element and keeps constant an angle of the other probe with respect to the surface of the test element is allowed to support the other probe.Type: ApplicationFiled: June 30, 2006Publication date: December 11, 2008Applicant: Independent Administrative Institution Japan Aerospace Explaration AgencyInventors: Hideki Yabushita, Tatsuyuki Nagai, Shigeyuki Matsubara, Norio Nemoto, Hiroshi Miyamoto
