Abstract: A PWM controlled multiphase DC motor apparatus has a multiphase DC motor, a current sensor, and a PWM controller. The DC motor has multiple windings which turn on and off during commutation at a commutation frequency. The current sensor is coupled to sense power supply current flowing in all windings of the DC motor. The PWM controller is coupled to control the DC motor using a PWM signal at selected PWM frequency with variable duty cycle. Using the feedback from the current sensor, the PWM controller maintains approximately constant torque in the DC motor by adjusting the duty cycle of the PWM signal. The PWM controller includes a soft switching circuit which manipulates a voltage used to generate the controlling PWM signal in a manner which causes linear slewing of currents in the windings during commutation. The linear current slewing occurs at a slew rate that is slow relative to the PWM frequency to thereby reduce torque ripple during commutation. The combined features of continuous PWM duty cycle control and linear current slewing during commutation significantly reduces torque ripple at the fundamental commutation frequency, as well as at the first few harmonics. A method for PWM control of a multiphase DC motor is also described.

Abstract: In a magnetic resonance method for imaging of a moving part of a body (106) temporary magnetic gradient fields (230) are applied and an echo signal (641, 642) is obtained after an excitation pulse (201). An image of the moving part is reconstructed from the received echo signals (240). The moving part introduces artefacts in the reconstructed image. These artefacts could be reduced when the instantaneous position of the moving part is known and the region of the moving part to be excited is adjusted according to this instantaneous position. This instantaneous position is derived from navigator signals (640). These navigator signals (640) could be generated independently from the other echo signals (641, 642) in the moving part of the body. A further reduction of artefacts in the image could be obtained by deriving a phase correction and a frequency correction from the navigator signals (640) and to apply the derived corrections to the received echo signals (641, 642). Also this method could be combined with ECG-triggering and respiratory gating.

Abstract: In an electron microscope it is sometimes important that specimens can be studied at a very low temperature (for example, that of liquid helium). In the case of known specimen holders the specimen is cooled by supplying the cooling medium via a bore in the specimen holder; this causes thermal drift of the removed specimen holder each time when a specimen is exchanged, and also an acoustic coupling (i.e. transfer of vibrations) exists with the dewar vessel connected to the specimen holder. In accordance with the invention, the specimen is arranged on the end ( 20 ) of the specimen holder (7) by means of a separate transport unit (13, 36) so that it is not necessary to remove the specimen holder (7) in order to exchange a specimen, with the result that the specimen holder is not heated. Moreover, the coupling to the cold source (22, 28) can take place via a flexible cooling conduit ( 30 ) which extends directly to the end ( 20 ) to be cooled and may be permanently connected thereto, thus avoiding the transfer of vibrations.

Abstract: A description is given of an optical inspection device for inspecting two oppositely located surfaces (3, 4) of a transparent object (1), for example a lithographic mask. The device is constructed in such a manner that for each inspection beam (a, c) the radiation path to the surface to be inspected (3, 4) is substantially equal to the radiation path from the surface to be inspected to a detector (29, 40), so that these paths comprise the same scanning element (10), preferably a mirror polygon. By virtue thereof, the radiation spots formed on the detectors are stationary and an inspection signal having a good signal-to-noise ratio is obtained.

Abstract: A hair styling instrument comprises a housing (8) having a front side (9), formed with at least one passage (10) for heated air. Elongate hair guides (12, 13, 14) project exclusively from the front side (9) of the housing (8) or, at least in the area of the passage (10), fixed elongate hair guides (12, 14) project from the housing (8). Movable ones of the hair guides (13) are movable between a first position, in which they project fully from the housing (8), and a second position, in which they project from the housing (8) at the most to a smaller extent than in said first position. With the movable hair guides (13) in the second position the hair styling instrument can be moved through wet tangled hair with a low resistance. Subsequently, when the hair is tidied and dried, a proper grip and hence a satisfactory styling performance is achieved with the movable hair guides (13) in the first position.
