Abstract: A silicon wafer is produced by growing a silicon single crystal ingot having a resistivity of 100 &OHgr;·cm or more and an initial interstitial oxygen concentration of 10 to 25 ppma by the Czochralski method, processing the silicon single crystal ingot into a wafer, and subjecting the wafer to an oxygen precipitation heat treatment so that a residual interstitial oxygen concentration in the wafer should become 8 ppma or less. A silicon wafer produced as described above shows little decrease in resistivity even after a heat treatment in device production etc. Further, if a silicon wafer is produced and heat-treated so that the wafer should have the above-defined initial interstitial oxygen concentration and residual interstitial oxygen concentration, slip dislocations in a subsequent heat treatment process are prevented irrespective of resistivity.

Abstract: The present invention is provided for accurately estimating an amount of angular disagreement of planes of polarization between two polarization-maintaining optical fibers when connecting the polarization-maintaining optical fibers. In the present invention, a distribution of the polarization-maintaining optical fibers by irradiating a light on the lateral side of the polarization-maintaining optical fibers. The positions and heights of peaks of brightness of a transmitted light produced by the irradiated light are varied to comply with the angular disagreement of an axis of polarization which traverses two stress applying sections toward the irradiation direction of the light of each polarization-maintaining optical fiber. The amount of angular disagreement of the planes of polarization can be accurately estimated from the positions and heights of the peaks.

Abstract: The invention provides a graphic form shaping apparatus which shapes, when a graphic form having certain symmetry with respect to a line and surrounded by a curved line is inputted, the input graphic form so as to be symmetrical with respect to a line. Apexes and maximal points and minimal points in horizontal and vertical directions of an input graphic form are determined as characteristic points, and the degree of symmetry with respect to a straight line interconnecting two of the characteristic points is measured. If the degree of symmetry satisfies a criterion determined in advance, then it is determined that the input graphic form is symmetrical with respect to the straight line, and the input graphic form is corrected based on the symmetry with respect of the straight line.

Abstract: In a point symmetry shaping apparatus used for a curved figure, any unrecorded symmetry figures are automatically shaped in a point symmetry manner within a short processing time. In the point symmetry shaping apparatus, a coordinate point which constitutes a symmetry center candidate point is calculated from all of center points of symmetry-judging-line-segments. A first point symmetry center candidate point/center point distance calculating unit calculates a distance between the symmetry center candidate point and the center point of the symmetry-judging-line-segment. A point symmetry judging unit judges a point symmetry of the input curved figure in such a manner that a calculation is made of a fluctuation value contained in the distances between the symmetry center candidate point and the center points of the symmetry-judging-line-segments, and the calculated fluctuation value is compared with a threshold value.
