  • Patent number: 7086145
    Abstract: The invention relates to an assembly device for microcomponents that are disposed in a magazine. The inventive assembly device does not require any optical systems and allows for an exact positioning of the microcomponents. The assembly will also be unaffected by any position changes of the microcomponents caused by wastage. The assembly device is provided with mechanical alignment devices that engage with or act upon adjustment structures of the magazine. The assembly device further comprises clamping devices for fixing the magazine and at least one plunger for ejecting at least one microcomponent from the magazine. An assembly platform is provided in the upper tool or in the lower tool of the assembly device and receives the microcomponents in a defined position. The invention further relates to a method for assembling microcomponents and to a corresponding magazine.

  • Patent number: 7041433
    Abstract: The invention relates to a flat coil and to a lthographic method for producing microcomponents with metal component sources in the sub-millimeter range. According to the inventive method, a resist material is structured by means of selective exposition and removing the unexposed zones and filling in the gaps between the resist structures with metal by means of a galvanic method to produe the metal component structures. The aim of the invention is to improve such a method so that the microcomponents can be subdivided during said process. To this end, a structured three-dimensional sacrificial metal layer is produced during the production of the microcomponent, said sacrificial layer delimiting the microcomponent and being removed once the microcomponent is due to be subdivided.

  • Patent number: 6906607
    Abstract: The object of the invention is to produce multipole magnetic systems that are composed of a plurality of individual magnetic components that preferably are made of rare-earth magnetic material. The invention relates to a method for producing and magazining at least one individual magnetic component, a magazine for at least one individual magnetic component by molding and for conventionally magnetizing the same. The invention further relates to a method of assembly for producing a magnetic system and to the resulting magnetic systems. The invention teaches that extremely flat multipole magnetic systems in the form of magnet rings or magnet strips and three-dimensional magnet bodies such as a magnetic scale, for example, can be produced by means of individual magnetic components that are directly adjacent to each other or are arranged at a distance by means of a molding material, for example.

  • Patent number: 6746819
    Abstract: The invention relates to a lithographic method for producing microcomponents with component structures in the submillimeter range. According to the inventive method, a structured adhesive layer is applied to a metal layer and then a photostructured epoxy resin layer is applied to said adhesive layer. Said epoxide resin is structured by means of selective exposition and removing the unexposed zones and filling in the gaps between the resin structures with metal by electroplating. The aim of the invention is to provide an adhesive layer that is suitable for photostructured epoxy resins, especially for SU-8 resist material and that prevents the resist material from being detached. To this end, the adhesive layer consists of polyimide or a polyimide mixture.

  • Patent number: 6700278
    Abstract: The invention relates to a disk motor with an armature disk, which is rotatably mounted and provided with permanent magnets, and with a stator which comprises a stator plate which is equipped with coils. The aim of the invention is to provide a disk motor that is as flat as possible and that is characterized by an improved smoothness of running. To this end, an annular soft-magnetic prestressing device is arranged concentrically on the stator plate in such a manner that at least one section of the prestressing device is located below the coil window of the coils in the axial direction. The armature disk may support an annular flux-return element opposite which the annular prestressing device is located in the radial direction. Said prestressing device has a cross-sectional contour that guides the magnetic lines of electric flux from the annular flux-return element to the coil window.

    Abstract: The invention relates to an assembly device for microcomponents that are disposed in a magazine. The inventive assembly device does not require any optical systems and allows for an exact positioning of the microcomponents. The assembly will also be unaffected by any position changes of the microcomponents casued by wastage. The assembly device is provided with mechanical alignment devices that engage with or act upon adjustment structures (42a-d, 44a-d, 45a-d) of the magazine (4). The assembly device further comprises clamping devices for fixing the magazine and at least one plunger (2a, b) for ejecting at least one microcomponent (3a, b) from the magazine (4). An assembly platform (8) is provided in the upper tool (101) or in the lower tool (102) of the assembly device and receives the microcomponents in a defined position. The invention further relates to a method for assembling microcomponents and to a corresponding magazine.
