Title: Structure analyzing method of crystal

Filed: 2008-08-18
Abstract: <P>PROBLEM TO BE SOLVED: To enable analysis even with respect to the origin of the sub-peak part separated from a main peak in X-ray diffraction measurement.  <P>SOLUTION: A sample such as a bulk crystal or the like is subjected to X-ray diffraction measurement to be structurally analyzed. At this time, a scanning angle is set to Δθ and the angle formed by a reflection index hkl surface and the surface of the sample is set to a surface angle θc to plot the horizontal axis of an X-ray diffraction profile as Δθ/sinθc while it is judged whether the peak expanse shape of an analyzing target peak is the peak expanse shape caused by the local twist distribution produced by the mosaicism of the crystal. This judge method is equipped with the process for judging whether the origin of the sub-peak appearing in the part separated from the main peak is the peak from the largely twisted specific part in a non-uniform twist distribution. That is, in a case that a sub-peak observing position does not depend on an index hkl even if the shape itself of the sub-peak does not coincide, it is judged that the origin of the sub-peak is the peak from the largely twisted specific part in the non-uniform twist distribution.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a spark plug with a thermal sensor capable of more precisely carrying out temperature measurement, through restraint of spark exhaustion at the tip part of a center electrode.  <P>SOLUTION: The center electrode 20 has a contact point 71 of a thermocouple 70 formed inside a tip part 22.
