  • Patent number: 6472658
    Abstract: An incremental position measuring system in the form of a three-grating sensor is optimized in such a way, that the degree of modulation (M) of the incremental scanning device, as well as the intensity (I) of a reference marker signal are relatively strong. To this end, a phase grating with an effective phase deviation of &lgr;/4 is embodied on a scale 2, as well as a reference marker (R) in the form of an amplitude structure. A compact structure is achieved by the divergent illumination of the grating located in front of the scale.

  • Patent number: 6467590
    Abstract: In order to prevent squealing of a disk brake, the disk brake has a brake disk with friction rings having locally weakening section moduli which detune corresponding to the natural oscillation mode. As a result, the natural oscillation mode of the brake disk is changed to such an extent that brake squealing is avoided.

  • Patent number: 6464290
    Abstract: A frame structure of a body for a motor vehicle and a method of making same. The frame structure includes at least one lateral support arrangement which extends in a longitudinal direction of the motor vehicle between a forward body region and a rearward body region. The at least one lateral support arrangement is arranged to arch over a vehicle occupant compartment above a belt line and is bounded by a roof of the motor vehicle. The at least one lateral support arrangement includes a tube support which is operatively connected with a first reinforcement in a forward body region of the motor vehicle and a second reinforcement in a rearward body region of the motor vehicle. The tube support forms a stiff frame composite for the at least one support arrangement by way of a holding device operatively arranged with the tube supports. The frame structure of the present invention is relatively simple to manufacture and provides optimal stiffness.

  • Publication number: 20020144866
    Abstract: A device can indicate the total load of a brake disk made of carbon-fiber-reinforced ceramic material. In order to create such a device, which can be used for brake disks and other friction elements made of carbon-fiber-reinforced ceramic material, an indicator element can be provided in the brake disk starting from the friction surface. The oxidation stability of this indicator element is reduced with respect to the material of the brake disk.

  • Patent number: 6460890
    Abstract: In order to cause a deformation or a yielding, in the event of a head impact onto a safety belt system of a passenger vehicle, a deformation element is interposed which deforms plastically and absorbs energy. So that an exchange of numerous parts is avoided, an arrangement for a belt level adjuster is configured so that after a head impact, only the deformation element needs to be exchanged.

  • Patent number: 6457483
    Abstract: In a fixture for ascertaining pressure losses in a pressure line (3) which can be blocked for a selectable unit of time by means of shut-off valves (11, 13), in which the consumers (4, 5) are connected to the pressure line (3) and the pressure line (3) is provided with a pressure watchdog (15), the blocked pressure line (3) can have an adjustable quantity of the enclosed pressurised medium supplied into it via a branch line (24) for a unit of time, and the pressure watchdog (15) is provided with a circuit (31) by means of which the pressure line (3) can be controlled depending on the operating status of the pressure watchdog (15). By means of this embodiment, it is possible with only a very minor scope of circuitry to test the pressure line (3) at any time or at selectable time intervals and, depending on the measurement result, to resume the supply to the consumers (4, 5) or to deactivate the pressure line (3).
