The present invention relates to novel anti-inflammatory and antiallergic compounds of the glucocorticosteroid series, methods of preparing such compounds, pharmaceutical compositions comprising them, combinations and therapeutic uses thereof. Alternatively, in order to obtain a sufficiently large sense diode current in a stable manner, the sense region is provided with a second region in which a distance from the main cathode region in a plan view of the semiconductor substrate is equal to or shorter than 298 \u03bcm. At their free end the jaws are provided with incisions and, adjoining these, with gripper-like parts jutting outwardly toward the central axis for the purpose of engaging mechanically andor frictionally with the fastener head from behind. A slide is mounted to the socket body to move horizontally. In a second embodiment, the countertwist device comprises a movable twist imparting member, which is adapted for reciprocal movement between an idle position for not treating or for threading the yarn and an operating position for treating the yarn by twisting it. The fuel cell separator plate includes at least one groove formed in a face of the separator plate so as to feed reactant gas to a membrane electrode assembly applied against the face of the separator plate, the groove comprising an inlet section and an outlet section.
