IPC: G01J3/447
Filed: 2004-03-11
Abstract: <P>PROBLEM TO BE SOLVED: To reconcile a time required for analysis with analysis accuracy in a well-balanced state.  <P>SOLUTION: In this ellipsometer 1, measurement is performed relative to some point on a sample S by a first spectroscope 8 and a second spectroscope 9. Analysis is performed by using a measurement result from the first spectroscope 8 and analysis is also performed by using a measurement result from the second spectroscope 9, and an approximate expression for approximating an analysis result relative to the second spectroscope 9 to an analysis result relative to the first spectroscope 8 is calculated. Measurement is performed relative to residual points on the sample S by the second spectroscope 9, and an analysis result acquired by using the result is corrected on the basis of the approximate expression. Since the second spectroscope 9 has a shorter measuring time, through having lower measurement accuracy, compared with the first spectroscope 8, the total measuring time becomes short, and since the analysis result relative to the second spectroscope 9 is corrected, the analysis accuracy is improved.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2004-03-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electric power steering device reducing deviation of an engaging position of a worm wheel and a worm caused by a change of temperature and allowing easy assembly.  <P>SOLUTION: Since there is a ball bearing 34 as a supporting base of a pinion shaft 2 immediately below the worm wheel 51, relative deviation of the engaging position of the worm wheel 51 and the worm 53 to an axial direction of the pinion shaft 2 is slight in quantity even when the temperature on the periphery of the electric power steering device is changed. A bearing hole 47 into which an outer ring of a lower needle bearing 36 is pressed and a bearing hole 45 into which the outer ring of an upper ball bearing 34 is pressed are formed on the same lower gear box 41. Also, since through processing by a boring tool from a bearing hole 45 side can be carried out, processing time is shortened, and concentricity of the bearing holes is enhanced. Thus, oscillation of the worm wheel 51 is reduced, and noise in an engaging part or abrasion of a tooth surface can be suppressed.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
