  • Publication number: 20160333929
    Abstract: A hydrodynamic plain bearing has a bearing shell with an inner surface forming a bearing surface for a rotating shaft or the like. The bearing surface, in order to form a bearing having a multi-wedge bore, has a plurality of surface segments arranged one after the other in the circumferential direction and each forming a circle segment having a radius R by way of the inner circumference of the surface segments. The center point of the circle segment of each surface segment is shifted relative to a center point of the bearing shell by an eccentricity. The bearing shell has two halves, each extending over 180° of the bearing surface and joined in a joint plane. At least one surface segment is offset from the center point of the bearing shell along an offset plane at an angle to the joint plane in the circumferential direction of the bearing shell.

  • Patent number: 9470986
    Abstract: A method for determining overlay error includes measuring asymmetry of radiation reflected from each of a plurality of targets on a substrate. The plurality of targets include a predetermined overlay offset. The method also includes comparing the measured asymmetry of the radiation reflected from each of the plurality of targets to the corresponding predetermined overlay offset of the respective target. Additionally, the method includes determining the overlay error of a point on the substrate as a function of measured asymmetry reflected from the point. The function is determined by fitting a polynomial or a Fourier series to a comparison of the measured asymmetry of the radiation reflected from each of the plurality of targets to the corresponding predetermined overlay offset of the respective target. The function limits an effect of linearity error.

  • Patent number: 9438085
    Abstract: The invention relates to a converter system (1, 1?, 1?) for an electric vehicle and in particular a lightweight electric vehicle. The converter system (1, 1?, 1?) has a supporting housing (10, 10?, 10?) for connecting to the vehicle, has an electromechanical energy converter arranged at least partially in the supporting housing (10, 10?, 10?), said electromechanical energy converter having at least one stator (21, 21?) and a rotor (22, 22?) which is rotatable relative to the stator (21, 21?) about a drive axis (7, 40), and has a power transmitting device which connects the rotor (22, 22?) to a connection element. To permit a particularly cheap design which is easy to maintain and to reduce thermal problems, the supporting housing (10, 10?, 10?) has at least one first (14) and one second axial portion (15). wherein (the first portion (14) has a greater diameter than the second portion (15) in a direction transversely with respect lo the drive axis (7, 40).

  • Publication number: 20160180517
    Abstract: A scatterometer is used in a dark-field imaging mode to measure asymmetry-related parameters such as overlay. Measurements of small grating targets are made using identical optical paths, with the target in two orientations to obtain separate measurements of +1 and ?1 diffraction orders. In this way, intensity scaling differences (tool asymmetry) are avoided. However, additive intensity defects due to stray radiation (ghosts) in the optical system cannot be avoided. Additive intensity issues strongly depend on the ratio between 0th and 1st order diffraction and are therefore strongly substrate (process) dependent. Calibration measurements are made on a few representative target gratings having biases. The calibration measurements are made, using not only different substrate rotations but also complementary apertures. Corrections are calculated and applied to correct asymmetry, to reduce error caused by stray radiation.

  • Publication number: 20160018207
    Abstract: A method for correcting an angular deviation between a real angle and an ideal angle between motion axes of a coordinate measuring device. The angular deviation depends on position, temperature, and/or loading mass. Values of a position-dependent angular deviation for partial measurement ranges of the coordinate measuring device are determined, and/or a difference between the angular deviation in a partial measurement range and a total measurement range, and the position-dependent angular deviation is corrected by using these values. Values of the temperature-dependent angular deviation for at least two different temperatures are determined and the deviation is corrected based on these.

  • Patent number: 9235141
    Abstract: An inspection apparatus measures a property of a substrate including a periodic structure. An illumination system provides a beam of radiation with an illumination profile including a plurality of illuminated portions. A radiation projector projects the beam of radiation onto the substrate. A detector detects radiation scattered from the periodic structure and separately detects first order diffracted radiation and at least one higher order of diffracted radiation of each of the illuminated portions. A processor determines the property of the substrate from the detected radiation. The plurality of illuminated portions are arranged such that first order diffracted radiation arising from one or more of the illuminated portions are not overlapped by zeroth order or first order diffracted radiation arising from any other of the illuminated portions.

  • Publication number: 20150326330
    Abstract: An AM/FM radio system for a vehicle that is selectively impedance matched to the particular tuned frequency of interest so that noise received by other frequencies does not affect the received signal. The radio system includes an HMI allowing a user to select an AM or FM radio station and a radio tuner responsive to a signal from the HMI identifying the selected radio station. The tuner tunes the radio system to the radio station, and provides a signal to the HMI identifying the radio station. The HMI places a message on a vehicle bus identifying the radio station that the radio tuner is tuned to. An antenna controller receives the message from the vehicle bus to selectively control an impedance matrix to provide impedance matching for the selected radio station frequency. The antenna controller also selectively tunes antenna radiating elements to the particular tuned frequency.

  • Patent number: 8908147
    Abstract: A method of determining an overlay error. Measuring an overlay target having process-induced asymmetry. Constructing a model of the target. Modifying the model, e.g., by moving one of the structures to compensate for the asymmetry. Calculating an asymmetry-induced overlay error using the modified model. Determining an overlay error in a production target by subtracting the asymmetry-induced overlay error from a measured overlay error. In one example, the model is modified by varying asymmetry p(n?), p(n?) and the calculating an asymmetry-induced overlay error is repeated for a plurality of scatterometer measurement recipes and the step of determining an overlay error in a production target uses the calculated asymmetry-induced overlay errors to select an optimum scatterometer measurement recipe used to measure the production target.
