In the spreading dimension acquiring step, circumferential spreading dimensions of each shroud-of two rotor blades are acquired. In the misalignment acquiring step, a misalignment amount in the direction of the axis between the shrouds of two rotor blades adjacent to each other in the circumferential direction is measured. In the correcting step, the spreading dimension acquired in the spreading dimension acquiring step is corrected on the basis of the misalignment amount acquired by the misalignment acquiring step. In the pre-twist amount acquiring step, the pre-twist amount of the blade is acquired on the basis of the spreading dimension corrected in the correcting step.Type: ApplicationFiled: February 24, 2017Publication date: October 31, 2019Applicant: MITSUBISHI HEAVY INDUSTRIES COMPRESSOR CORPORATIONInventors: Yuzo Tsurusaki, Yuki Nakamura, Yuichi Sasaki

Publication number: 20190310755Abstract: In a coordinate correction apparatus, a coordinate acquisition unit sequentially acquires coordinates of touch positions on a touch panel when a touch operation is continued on the touch panel. When the coordinate acquisition unit acquires first coordinates which are coordinates of a new touch position, a coordinate correction unit calculates a weighted average of the first coordinates and second coordinates determined from coordinates of a past touch position acquired by the coordinate acquisition unit, with applying weighting that varies according to a touch movement amount on the touch panel. The coordinate correction unit outputs a calculation result as corrected coordinates. An application unit uses the corrected coordinates.Type: ApplicationFiled: March 22, 2016Publication date: October 10, 2019Applicant: Mitsubishi Electric CorporationInventors: Yuichi SASAKI, Atsushi HORI, Kentaro MORI, Hiroyasu NEGISHI
