摘要:
New imidyl-benzenedicarboxylic acid derivatives, in particular 5-maleimidyl-isophthalic acid derivatives and 5-(nadic acid-imidyl)-isophthalic acid derivatives, and a process for their manufacture are described. These imidyl-benzenedicarboxylic acid derivatives are suitable for the manufacture of crosslinkable polymers, above all polycondensation and polymerization products, which are distinguished by good processability and good solubility in the customary organic solvents.

The imidyl compounds, according to the invention, of the formula I are suitable for the manufacture of polymers which can be crosslinked by light, which polymers can be, for example, polyesters, polyamides, polyamide-imides, polyimides, polyester-polyamides, polyester-amide-imides, polyethers, polyamines, polysaccharides and polysiloxanes. Polymers of this type are suitable for carrying out photochemical processes. Compared with known polymers, the polymers based on the imidyl compounds according to the invention have the advantage that they are photochemically substantially more sensitive. In addition, this sensitivity can also be further increased effectively by a combination with sensitizers.
摘要:
An antenna coupler for testing a mobile-radio device with a coupling element formed in a flat manner by strip conductors on a printed-circuit board and with a retaining device formed on a first side of the printed-circuit board for positioning a mobile-radio device in the vicinity of the coupling element. On the first side of the printed-circuit board, at least one slit structure is introduced into an ground metallization formed there. For feeding the slit structure serving as the coupling element, at least one stripline formed on the second side facing away from it forms a microstripline with the ground metallization remaining between the slit structure of the first side.

Disclosed herein is a gear selection method and device for an automatic transmission for a traction phase (Z2) after a coasting phase (S) of a motor vehicle. According to the method, in a traction phase (Z1) before the coasting phase (S), a sliding average value of the rotational speed level (n) and/or of the traction force level (Fx) is formed depending on the particular velocity (v) and particular gradient (ST) and is taken into consideration for defining at least one gear choice of the automatic transmission for the traction phase (Z2) after the particular coasting phase (S).
摘要:
The method for reconstructing the three-dimensional shape of the surface (14) of at least a portion of an ear canal (18) and/or of a concha comprises—for each of a multitude of points (12) on said surface (14)—the step of using a chromatic coded distance measurement technique for determining a distance value (40) representative of a distance to said point (12); and further comprises the step of reconstructing said three-dimensional shape based on said multitude of distance values (40). The system for reconstructing the three-dimensional shape of the surface (14) of at least a portion of an ear canal (18) and/or of a concha, comprises a distance measurement unit for determining—by means of a chromatic coded distance measurement technique and for each of a multitude of points (12) on said surface (14)—a distance value (40) representative of a distance to said point; and a reconstructing unit (50) operationally connected to said distance measurement unit for reconstructing said three-dimensional shape based on said multitude of distance values (40).
