Inventor: MACKELVIE JOHN S
IPC: H02K29/12
Filed: 1986-07-16
Abstract: Novel winding arrangements and control circuits for brush less direct-current motors are described. Stator windings are arranged to produce an essentially continuous torque in each winding phase from D.C. current pulses each of about one-half the duration of a two-pole cycle of rotor movement. An electronic control circuit comprises one electronic power switch for each winding group or winding phase in the stator windings. One or two D.C. current pulses are applied to the windings for each two-pole cycle of rotor movement, depending on the arrangement of the coils. CEMF voltage generated in the coils is sensed and a change in the polarity thereof is used to control switching of the D.C. current between coils.

Abstract: A diversity receiver includes first and second receivers (3. 41, a first switch (6). a comparator (5), a second switch (7), and a controller (8). The first and second receiver (3. 4) have receiver antennas (1.2) and generate demodulated signals and electric field detection outputs in accordance with received electric fields, respectively. The first switch (6) performs switching between the demodulated signals from the first and second receivers (3, 4) in accordance with an output switching control signal and outputs a selected demodulated signal. The comparator (5) compares the electric field detection outputs from the first and second receivers (3. 4), respectively. and supplies the output switching control signal to the first switch (6). The second switch (7) turns on/off a power source of the first receiver (3) in accordance with a power source switching control signal. The controller (8) receives the electric field detection output from the second receiver (4), calculates an average intensity of the electric field, and supplies the power source switching control signal to the second switch (7) in accordance with the average intensity of the electric field.

Abstract: The invention refers to a holding device consisting of holding head and holding shaft for pick-up, transport, and targeted deposit of small components, namely preferably for supplying circuit boards with electrical SMD switching elements. According to the invention, the holding head is designed so that upon a pressure in the direction of the components to be picked up, a bistable switching element is activated and consequently, the adhesion of the component as well, and upon the next pressure in the same direction, it is again deactivated. This saves specific control actions to activate and deactivate a compressed air source or other adhesive devices.

Abstract: The invention relates to a catch device against undesired rolling of a roller door. A first worm wheel (2), which is connected to the roller door shaft (4) in a rotationally fixed manner, and a second worm wheel (5), which is mounted rotationally movably with respect to the first worm wheel (2) and the roller door shaft (4), mesh with the driving worm (1). The second worm wheel bears driver elements (7), which displace the blocking bodies (8) within a frictional locking mechanism (6-10) between the supporting surfaces (9, 10). During normal operation, the blocking bodies (8) are located approximately in the region of the centre of the supporting surface (9), so that the roller door shaft (4) runs freely within the stop (6) fixed to the housing. In the event of disturbance, for example wear of the teeth of the first worm wheel (2), a rotation of the two worm wheels (2, 5) relative to each other leads to a positional change of the driver elements (7) and thus of the blocking bodies (8) so that the roller door shaft (4) is blocked by means of the blocking bodies (8) directly against the stop (6) which is fixed to the housing, without the blocking force having to be transferred from the second worm wheel (5).
