  • Publication number: 20250109969
    Abstract: A scanning element for an inductive position measuring device includes a multilayer circuit board having a first receiving conductive path extending along a first direction and an excitation track. The first receiving conductive path is formed from a plurality of first conductive path sections that are wired in series. Along a subsection, two first conductive path sections are arranged in the structure of the circuit board, offset to each other with respect to a third direction and concurrently. Along a first section, which is arranged offset to the subsection in the first direction, a further one of the first conductive path sections extends in the structure of the circuit board, without a first conductive path section extending concurrently to the further first conductive path section with respect to the third direction.

  • Publication number: 20240426593
    Abstract: An inductive angle measuring device includes a sensing element and a scale element rotatable relative to the sensing element. In a first receiving track, the sensing element includes a first receiving conductive path and a second receiving conductive path, by which a first signal can be generated and a second signal can be generated. The first and second signals have a first phase offset relative to each other. The sensing element further includes a fifth receiving conductive path, a sixth receiving conductive path, a seventh receiving conductive path, and an eighth receiving conductive path. The fifth and sixth receiving conductive paths are connected in series with each other, so that a first overall signal can be generated by the fifth and sixth receiving conductive paths. Furthermore, the seventh and eighth receiving conductive paths are also connected in series with each other, so that a second overall signal can be generated by the seventh and eighth receiving conductive paths.

  • Patent number: 7883578
    Abstract: Homogeneity residuals of the refractive index have a strong influence on the performance of lithography tools for both 193 and 157 nm application wavelengths. By systematic investigations of various defects in the real structure of CaF2 crystals, the origin of homogeneity residuals can be shown. Based on a quantitative analysis we define limiting values for the individual defects which can be either tolerated or controlled by optimized process steps, e.g. annealing. These correlations were carried out for all three relevant main crystal lattice orientations of CaF2 blanks. In conclusion we achieved a strong improvement of the critical parameters of both refractive index homogeneity and striae for large size lens blanks up to 270 mm diameter.

  • Publication number: 20060254046
    Abstract: An armature for an electric motor has a lamination stack on a shaft with a commutator mounted on one end of the shaft. Magnet wires wound in slots in the lamination stack, the commutator and armature shaft are at least partially encapsulated in a first plastic, such as by insert molding. The commutator has a commutator ring divided into a plurality of segments with slots between the segments that are filled with a second plastic when the commutator is made by molding a core of the second plastic, such as phenolic, in the commutator ring before the commutator ring is mounted on the armature shaft. Where the commutator is a tang type commutator, the commutator ring has notches at axial ends of the slots which is filled with the second plastic when the second plastic is molded. The mold used to mold the first plastic includes projections that extend between the tangs of the commutator and against the notches at axial ends of the slots of the commuter.

  • Publication number: 20060001885
    Abstract: The present invention relates to a method and a device for quantitative determination of the optical quality of a transparent material. In the method, a light beam is incident on the sample made of the transparent material, in order to form a scattering volume in the sample, wherein light scattered in the scattering volume at a predefined scattering angle (?s) is imaged on a light-sensitive element and wherein signals of the light-sensitive element are integrated or added up over at least a portion of the scattering volume in order to determine a measured value representing the optical quality of the transparent material of the sample. Signal contributions which do not originate from scattering of the incident light beam at the light entry or light exit surfaces of the sample are used exclusively to determine the measured variable.
