A microfabricated magnetic field transducer uses a magnetically sensitive structure in combination with one or more permeable magnetic flux guides. Using the monoamino compound, an organic luminescence device is provided, which exhibits a luminescence hue with extremely high purity, and having an optical output of a high luminance with a high efficiency and a long life time. As the cannula is withdrawn, filler material in the injection control device is uniformly deposited into the tract or tunnel via the automatic metering system. The first arm is length adjustable such as to adjust the orientation of the bracket. The imaging channels are configured to independently examine different spectra of the image of the biochemical arrays. Exhaust is passed either directly or through a vacuum pump to the atmosphere.
