    摘要: A three-phase spindle motor has three terminals each driven with pulse width modulated signals. Rotation of the motor is controlled by iteratively measuring an electrical period of the motor, determining a rotational position of the motor, and synchronizing the sinusoidal pulse width modulation of the spindle motor with the measured electrical period. The electrical period of the motor is measured by detecting zero crossings in the a back electromotive force induced at a first terminal of the motor and determining the time between successive zero crossings. The rotation position of the motor is determined based upon the last measured electrical period and a location of last detected zero crossing. The zero crossings are detected by selecting a time window during which the back electromotive force signal is sensed for zero crossings. The time window is selected as a function of the last measured electrical period and the rotational position of the motor.

    摘要: A multiple adhesive bead applicator has a handle member and a cross member. A network of adhesive distribution tubes is attached to the application and extends from the handle member to multiple distribution points in a preselected spacing on the cross member. Such an application is useful in a method for applying a cover member, such as an elastomeric membrane or insulation board, to a roofing substrate by first positioning the membrane adjacent a work area, then dispensing multiple beads of an adhesive onto the substrate in a preselected spacing and in a single pass and contacting the adhesive beads with the cover member.

    摘要: A recording system stores recording cycle information identifying the parameters for recording user data on a particular data sector. During a subsequent operation, the recording system employs the recording cycle information to select a different set of parameters for recording new user data at the particular data sector. One of the parameters might identify a recorded pattern in a balance pad at the data sector, and another one of the parameters might identify a scrambler seed value. By employing a different set of recording parameters for each occurrence of recording user data at the particular sector, sample timing of, for example, a read channel might be based on an average of easy and hard transitions.

    摘要: The present invention relates to isolated canine animal plasma, a method for isolating canine animal plasma, plasma obtained form an immunised or hyperimmunised canine animal and treating a canine animal with the isolated canine animal plasma. The method includes the step of selecting a canine animal having a blood group compatible with a recipient canine animal having an unmatched blood group, namely, selecting a canine animal for a blood group that does not cause plasma transfusion reaction and/or haemolysis. In one form, the method includes the step of immunising or hyperimmunising a canine animal plasma donor with one or more antigens of a canine animal pathogen. The pathogen is preferably a bacteria or virus.

    摘要: A handle assembly for holding together a pair of bulky fluid supply containers, such as liquid foam reaction product containers is provided that has a unique force exerting characteristic. The two containers are encircled by a flexible band capable of tightening, while a wire form member is provided that attaches to the supply container handles. This wire form member may serve as a handle and it has two diverging leg portions with free ends that engage the handles of the supply containers. The leg portions exert an outward force due to their divergence on the supply containers to bias them outwardly against the band.
