    摘要： A chuck for use in a percussion drill or the like has a unit for securing the chuck jaws against unintentional loosening during operation. The securing unit moves from an unlocked position in which a tool can be received by the chuck jaws to a locked position automatically for drilling operations without the use of a key. The securing unit includes a first surface (22) upon which a sliding member (21) is slidable to be received in a recess (26) during the shaking caused by drilling, so that coupling members (15, 19) between a securing sleeve (17) and a clamping sleeve (13) engage with one another.

    摘要： Polymer mixtures containing a first long-chain polymer and a second short-chain polymer. The structural parameters of the two polymers are coordinated in such a way that a polymeric material is obtained which is easier to process while being provided with improved mechanical properties and in part also improved thermal properties compared with the first polymer at suitable conditions for producing the polymer mixture as a result of networks being formed and heterocrystallization taking place.

    摘要： The stator winding of a brushless D.C. motor receives two current pulses per 360.degree.-el. of rotor rotation, each current pulse being furnished via a respective current path. Each current path contains at least one power transistor switch having conductive and non-conductive states. These states are determined by respective driver transistor switches; when the driver transistor switch is in a high-output-impedance state the respective power transistor switch is rendered conductive, but when in the low-output-impedance state it renders the power transistor switch non-conductive. In various ways disclosed herein measures are taken to prevent the power transistor switches of both current paths from being simultaneously conductive. This may be accomplished using inherent or discrete base-emitter capacitances so connected that a power transistor switch is switched off abruptly but switches-on only after the elapse of a predetermined delay. Alternatively, the Hall voltage produced by the motor's rotor-position-sensing Hall cell may be applied to comparators such that the power transistor switches are not even commanded to conduct except during respective periods each shorter than 180.degree.-el.

    摘要： A three-phase brushless dc motor includes a permanent-magnet rotor magnet arrangement having at least four poles and a Y-connected, or star-connected, three-phase stator winding. The winding's phases are arranged non-overlapping in slots of a slotted stator, the currents flowing in the three phases being controlled via at least three semiconductor elements by at least three magnetic-field-sensitive rotor position sensors. Each sensor is associated with a respective two of the winding's three phases and triggers a commutation which switches off the current in one of the associated two phases and switches on the current in the other of the associated two phases. The sensors are located to sense the permanent-magnet flux emanating from the rotor poles themselves. The rotor position sensors are provided at special angular locations on the stator. Each sensor is provided at an angular location at which there is not to be found, neither prior to nor subsequent to the commutation associated with that sensor, any energized stator pole; this may mean that the sensor location is (i) an angular location at which no energizable stator pole whatever is present, and it may mean that the sensor location is (ii) an angular location at which an energizable stator pole is in fact present, but during motor operation this energizable stator pole is in an unenergized state prior to a commutation associated with the particular sensor in question and likewise is in unenergized state subsequent to that commutation.
