Abstract: An evaluation method to efficiently and precisely measure high-density oxygen-precipitation defects in the bulk of a silicon wafer is disclosed. A number of silicon wafers containing oxygen-precipitation defects are provided. The SPV method is utilized to measure the diffusion length of the minority carriers in the silicon wafers. The density of oxygen-precipitation defects is measured by the infrared tomography method. The diffusion length and the defect density are plotted and are found to be correlated. That is, the SPV measured diffusion length of the minority carriers and the defect density obtained by the infrared tomography method have specific relationships. A constant A can then be obtained from the plot. The diffusion length L of minority carriers in silicon wafers provided for evaluation is measured by the SPV method. Finally, the bulk oxygen-precipitation defects density can be calculated from the formula A.times.L.sup.-2.

Abstract: A universal tape measure including a housing formed with a downward extending opening on a lateral side. A lower end of the opening is disposed with a pen tip opening. An inner wall of the opening is disposed with intersecting cross lines which outward extend to mark a right angle cutout. The tape measure is marked with scales such as metric system scale, British Imperial scale and/or other scales. The tape measure is further formed with a circle center hole. The universal tape measure has the functions of drafting a circle, measuring whether an article is vertical and measuring the horizontal distance between two points on different levels.

Abstract: A method and a device for positioning boot bindings to be fitted depending on an axial deviation of a body of a snow board player in which a pair of fore and back loading disks (21) and (21') are arranged rotatably on a base (11) and each of the loading disks (21) and (21') can be fixed to a turning direction at an arbitrary angle. A player stands with his boots on the fore and back loading disks (21) and (21'). One of the loading disk (21) or (21') is temporarily fixed at a predetermined position to detect the axial deviation of the body by twisting an ankle right and left, while the axial deviation of the body on the other loading disk (21) or (21') is detected by a similar operation, thereby fixing fore and back boots on the snow board so as to provide an angular difference corresponding to an angular deviation ratio of both angles thus determined.
