Abstract: A joint structure has a male-side metal joint (3) fixed on a column (1) and a female-side metal joint (4) fixed on a beam (2). The two metal joint (3, 4) are common joints having the same shape, and have a first contacting surface (81), a second contacting surface (82) which continues from the back thereof and curves upward at an angle of less than 90.degree., and a third contacting surface (83) which continues from the front of the first contacting surface and curves downward at an angle of 270.degree. or more. When one of the two metal joints (3, 4) is put on the other, these contacting surfaces contact intimately with each other. If the two joints are fastened by a fastening bolt (5) in this state, the beam (2) is jointed to the column (1). Because the first to third contacting surfaces (81 to 83) incline, the joint metals (3, 4) do not get out of place longitudinally or vertically. Hence the simple subsequent operation of fastening and so forth can be carried out easily.

Abstract: For the directional drilling of boreholes, the orientation of accelerometer modules, magnetometer modules and gyroscopes or other directional sensing devices must be accurately known and maintained with respect to each other and to external mounting devices. This is accomplished by a self-aligning segmented cylindrical connection which accurately maintains modules in rotational alignment with each other for all three directions of rotation, even if the mating surfaces of the connection experience wear due to rough use in the drilling application or repeated calibration in a calibration fixture. Wedged surfaces on each of the male and female portions of the connection constitute the mating surfaces, and are the only surfaces at which the male and female portions contact one another. A depression between the mating surfaces defined by the female portion permits reproducible angular displacement of one portion with respect to the other even if one or both portions are worn.
