Patent number: 9207211Abstract: An object is to improve the precision of estimating a blockage ratio or a deposited-scale thickness. In a deposit measurement apparatus that estimates a blockage ratio of a gap between a wall surface of a through-hole and an outer surface of a heat-conducting pipe or the thickness of a deposit deposited at the gap, an eddy-current flaw detection probe (61) acquires an eddy-current flaw detection signal by scanning inside the heat-conducting pipe with a sensor; and a processing device (62) estimates the blockage ratio at the gap or the thickness of the deposit deposited at the gap by using the eddy-current flaw detection signal for the gap of the pipe-supporting-plate protrusion in the through-hole.Type: GrantFiled: November 10, 2011Date of Patent: December 8, 2015Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Kayoko Kawata, Yuko Yamamoto, Masaaki Kurokawa, Masaharu Michihashi, Naoto Kawase

Patent number: 9121601Abstract: An insertion-hole blockage-rate evaluation system is applied to a heat exchanger that includes a heat transfer tube and a tube support plate having an insertion hole formed therein for inserting the heat transfer tube therethrough. The tube support plate is displayed in a three dimensional manner in an elliptical diagram with a ratio between a long axis and a short axis being in a range from 1.0 to 2.0 inclusive, each of the tube support plates is serially arranged so as not to overlap on each other, and the insertion-hole blockage-rate evaluation system includes an imaging process of color-coding and displaying the diagram displayed in the three-dimensional elliptical shape according to a value of a blockage rate of the insertion hole acquired by checking the blockage rate of the insertion hole.Type: GrantFiled: March 23, 2012Date of Patent: September 1, 2015Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Yuji Kohashi, Naoto Kawase, Kayoko Kawata, Takashi Inagaki, Masaharu Michihashi

Patent number: 6993178Abstract: A lifetime evaluating system includes a digitalizing unit, an acquiring unit and a determining unit. The digitalizing unit digitizes an original metallographic image of a mechanical element to form a digital image. The acquiring unit acquires a plurality of labels from the digital image. Here, each of the plurality of labels is a set of pixels with a predetermined property. The determining unit classifies the plurality of labels into a class of voids and a class of non-voids based on evaluation data. A lifetime of the mechanical element is determined based on a number of labels in the void class and a size of each of the labels in the void class.Type: GrantFiled: April 5, 2002Date of Patent: January 31, 2006Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Masashi Ozaki, Nobuhiko Nishimura, Nobuya Yoshimoto, Shintaro Kumano, Naoto Kawase
