    摘要: A direction-finding method for determining an incident angle of a high-frequency electromagnetic signal in a system including at least two receiving antennas spaced apart by a known distance. the antenna output signals of the at least two receiving antennas are converted, together (in accordance with a multiplexing procedure) or individually, into the frequency domain through a Fourier transformation, followed by a conversion into an IF range and an A/D conversion. In this range, the phase difference between the output signals is determined and the signal frequency of the incident wave is determined through a phase-sequence analysis. The incident angle of the incident wave is determined from the phase difference and the signal frequency.

    摘要: The invention relates to components made of steel, more particularly outer joint parts and inner joint parts of constant velocity joints, and to a process of heat treating such components made of steel. The heat treatment operation includes the process stages of nitriding, induction surface layer hardening and tempering, which processes follow one another. As a result of the nitriding operation, the joint parts are provided with a surface layer (15) including nitrides and a diffusion layer (18) positioned thereunderneath. The subsequent induction hardening process causes the diffusion layer (18) to be hardened, so that it comprises good supporting characteristics for supporting the surface layer (15) positioned above same.

    摘要: An X-ray analysis apparatus having a curved paraboloid-shaped curved graded multilayer Bragg reflector (5) is characterized in that the layers of the reflector (5) are directly introduced onto a concave curved surface of a paraboloid-shaped hollow substrate and a maximum allowable shape deviation for the concave substrate surface facing the reflector is &Dgr;p={square root over (2px)} &Dgr;&thgr;R, and having a maximum allowable waviness Δ ⁢   ⁢ y Δ ⁢   ⁢ x = 1 2 ⁢ Δθ R and a maximum allowable roughness &Dgr;y=d/2&pgr;, preferentially &Dgr;y≦0.3 nm, wherein the X radiation (7) impinges on the curved surface of the reflector (5) at an angle of incidence 0°
