Title: Method for representing equimagnetic potential contour
Inventor: TAKAHATA MITSUHIRO
IPC: G06F19/00
Filed: 1994-07-04
Abstract: PURPOSE:To suppress the positional shift of magnetic peak by making smooth the equipotential contour even when the number of measuring point is few using an interpolation harmonic function containing field attenuation terms of sine and cosine curves. CONSTITUTION:Magnetic data, positional data, etc., at 25 points are inputted to a CPU 1 where 5 points are picked up in the lateral direction in order to determine the n-value of field attenuation term. The n-value is subjected to least minimum normalization in order to determine the unknown numbers related to sine and cosine. Interpolation calculation is then performed at 21 points in the lateral direction using the unknown numbers and a variable N(N=0) is incremented by 1 in order to perform calculation in the lateral direction for next row. The step is repeated 5 times and 5 points are picked up in the longitudinal direction for N=5. Subsequently, interpolation calculation is performed at 21 points in the longitudinal direction in order to determine the n-value of field attenuation term before a variable M(M=0) is incremented by 1. The step is repeated 21 times to produce a mesh data at 441 point for creating a contour map. Since the interpolation is effected appropriately, the contour coverage is made smooth and the positional shift of field peak is suppressed.

Title: Correction method for dynamic balance of rotating machine
Inventor: UEDA MOTOHIKO
IPC: F04D23/00
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To obtain a correction method in which a dynamic balance is obtained with high accuracy by correcting not only the imbalance of a component in the radial direction but also the imbalance of a component in the axial direction. SOLUTION: The dynamic balance of a rotating body is measured, and a dynamic imbalance mass at a prescribed mass is then formed in a position which is deviated by a prescribed angle from a first dynamic imbalance position which is measured (a trial machining operation). After that, the dynamic imbalance of the rotating body is measured again, and the dynamic imbalance is corrected. Thereby, since the dynamic imbalance mass at the prescribed mass is added to the imbalance of a component in the axial direction in addition to a first dynamic imbalance mass, the imbalance becomes large as compared with that before the trial machining operation. Consequently, since the imbalance of the component in the axial direction can be measured with high accuracy after the trial machining operation, a dynamic balance can be obtained with high accuracy.
