  • Patent number: 7995205
    Abstract: Apparatus and methods are disclosed for viewing low-birefringence structures within samples directly, with the eye, in real-time. The sample is placed between an entrance polarizer and analyzer polarizer, the transmission state of one of which is changed dynamically to create a modulated view of the scene; against this background, birefringent structures are visible because of their different appearance when modulated. Modulation rates of 4 or more states per second; use of 4 or more states, or even a continuum of states, which lie substantially on a latitude line on the Poincare sphere; and orientation of the polarization components to produce a uniform background; produce a clear view that does not produce operator fatigue. Broad-band wavelength operation spanning 50 nm or more, or the whole visible range, is achieved, and it is compatible with integration into other microscopy modes such as Hoffman relief contrast.

  • Patent number: 7993555
    Abstract: Provided are a structure of molding tools and an injection molding device that can easily perform molding of an optical element even from a resin of low velocity or the like and can suppress any negative effects by air. The structure of the molding tools includes between the molding tools (61, 62) a fixed molding tool (61) and a movable molding tool (62) and an O-ring (63a) for keeping air tightness and a resin seal (63b) for preventing any resin leakage. The O-ring (63a) performs decreasing of the pressure in a cavity (CV) formed by joining the molding tools (61, 62), whereby the vacuum molding in which resin supply and resin curing is carried out under a decreased pressure can be performed. Accordingly, the effects such as prevention of air bubbling due to air trapping by injected resin within the cavity (CV) can be attained. Furthermore, the resin seal (63b) can prevent any resin leakage from the molding tools (61, 62) even when the resin having a low viscosity is used.

  • Patent number: 7994779
    Abstract: Presented is a method for continuously determining the tensile force F in a cable of a parking brake that includes transmitting the tensile force F to a cable grommet coupled to a first end of an expandable intermediate part that includes a magnet and/or a magnetic sensor. The first end of the expandable intermediate part faces away from a drive spindle coupled to a second end of the expandable intermediate part. The method further includes changing the length of the expandable intermediate part in the direction of its longitudinal axis in response to the transmitted tensile force F, moving the magnet and the magnetic sensor relative to each other in response to the change in length, changing the signal voltage of the magnetic sensor in response to the relative movement between the magnet and the magnetic sensor, and determining the tensile force F from the respective signal voltage.

  • Patent number: 7993065
    Abstract: A printer is disclosed having a media unit which can move relative to a printing unit. Until now, difficulties in aligning the media unit in the printer always resulted in a poor printing quality. To rectify this, the disclosed printer provides that the printing unit is designed so that it can move inside the housing, and elements are provided for aligning the printing unit with the media unit so that the printing unit and the media unit can be aligned with one another when the media unit is pushed in the direction of insertion. A resilient element enables the printing unit to be advantageously tensioned, in a manner that equalizes tolerances, against the support of the media unit in an operating position. This enables an advantageous equalization of work tolerances and positional tolerances, and the position of the print head relative to the medium to be printed.
