Abstract: A pointer instrument mechanism has a chassis (6) which is formed by a one-piece preform of plastic and has a plane dividing wall (7). Mounted on the one side of the dividing wall (7) is a measured value generator (G) which has a lifting element (3) facing the dividing wall (7) and converts changes in the measured variable into mechanical deflections of the lifting element (3) which are directed essentially perpendicularly to the dividing wall (7). On the other side of the dividing wall (7) a pointer shaft (5) is mounted perpendicularly to the dividing wall (7). A measured value converter (U) converts the deflection of the lifting element (3) into a rotation of the pointer shaft (5). For this purpose, in the dividing wall (7) there is a cut- out in which a rocker is mounted so as to be capable of swivelling about an axis parallel to the dividing wall (7). The rocker forms a part of the measured value converter and connects to the lifting element (3) in such a way that it is swivelled by means of the deflection of the lifting element (3). Further components of the measured value converter convert the swivelling movement of the rocker into a rotation of the pointer shaft (5). <IMAGE>

Abstract: Bei Prismenkopplern zur Einkopplung (Auskopplung) von Licht in einen (aus einem) optischen Schichtwellenleiter (11) ist der Einkoppelwinkel (Auskoppelwinkel) in der Regel temperaturabhängig. Diese Temperaturabhängigkeit soll beseitigt werden. Diese geschieht durch geschickte Wahl des Prismenwinkels und des Prismenmaterials bzw. mit einer Kombination von zwei Prismen (4, 5), durch die erreicht wird, daß der Temperaturgang des Brechungsindex (n effo ) des Wellenleiters (11) durch einen entsprechenden Temperaturgang im Prisma (2) oder der Kombination aus zwei Prismen (4, 5) kompensiert wird. Für einen Schichtwellenleiter in LiNbO 3  kann eine geeignete Prismenkombination wie folgt gewählt werden:
     Ein Prisma (4) besteht aus LiNbO 3  und weist einen Prismenwinkel y'= 89,2° auf.   Ein Vorsatzprisma (5) besteht aus Polystyrol und weist einen Prismenwinkel β = 36,4° auf.

Abstract: When induction motors are lightly loaded, their powerfac- tors and efficiency are poor but in the arrangement power factor is controlled regardless of load. An induction motor (10) is connected by way of a triac (12) to a supply (11). The voltage across the triac (12) is monitored by a comparator (21) for voltage steps which correspond to current turn-off and a signal is developed at the output of an amplifier (19), which represents error from required phase lag. A comparator (17) and trigger pulse generator (16) trigger the triac (12) in accordance with the error. An override circuit (31) overrides the control system during starting. A number of further induction motors (28, 29) may be connected in parallel with the motor (10). Additional circuits deal with problems arising when a three-phase induction motor is connected by three wires only.
