Title: Method and apparatus for reinforcement of analysis of frequency region
Inventor: RONARUDO DABURIYU POTSUTAA
IPC: G01R23/16
Filed: 1994-01-24
Abstract: PURPOSE: To achieve a more accurate frequency analysis by using a sampler for generating sampling time domain data, a DFT means for generating frequency domain data, and a means for generating interpolated frequency domain data. CONSTITUTION: A rectangular shaping window function having the width equal to a period T' does not generate a leak error in a frequency spectrum. The length T of a total time record is enough to meet the required over-sampling factor of an interpolation window function. Also, a zero value is padded to a time interval between T' and T, and when the fast Fourier transformation FFT applies, a spectrum sampled at the frequency interval of 1/T can be obtained. Thereafter, a convolution kernel is applied, and the value of a resulting curve is measured at the frequency interval of 1/T', thereby again implementing a sampling process. The results of this re-sampling process are a discrete linear set at a principal frequency and each harmonic frequency. Thus, no leak error is generated with the rectangular shaping window function.

Title: Tooth face modifying method for gear wheel
Inventor: UMEYAMA MITSUHIRO
IPC: B23F19/00
Filed: 1995-01-19
Abstract: PURPOSE: To keep a working communication error small regardless of mis- alignment in arranging a gear wheel. CONSTITUTION: Mis-alignment in arranging a gear wheel, that is a parallelism error and a stagger error, is converted into a pressure angle error and a spiral angle error, then a minimum crowning quantity and a tooth roundness quantity (A0) are found in such range as unbalanced contact does not generate even in a tooth face having these errors. When modification is carried out with taking account of manufacturing tolerance (diagonal area), bias modification is put into practice for a working communication error to be a same extent as modification quantity in a lower limit of tolerance (A1) with measuring an acutual modification quantity. A modification quantity is made small as to a central part of the tooth face contacting in the case of small mis-alignment.
