摘要： A three-phase induction motor is subjected to countermeasure for the rotor and the stator in order to remove two harmonic components of the orders causing a torque ripple, among a plurality of harmonic components included in a magnetic flux generated in an air gap between a stator core and a rotor core. In the three-phase induction motor, conductor grooves of the rotor core are skewed by an electrical angle of 2.pi./n where n is the order of one of the harmonic components to be removed. In the stator, the number of slots (N) is selected so that an equation N=l.times.m.times.q is satisfied, where l=the number of poles, m=the number of phase, and q is a non integer number representing the number of slots per pole per phase, and the stator winding pitch is determined according to the order of another harmonic component to be removed.

摘要： A three-phase induction motor includes winding slots and a stator winding. The number of winding slots per pole per phase is a noninteger. The stator winding is a three-phase balanced winding. A pitch s of the winding satisfies s=(r-t)/r or s=r/(r+t) (where t is an odd number and r is the order of a harmonic wave to be suppressed).

摘要： A contact location detecting mechanism (1) of a touch signal probe (10) includes a rotary motion generator (30) for scanningly moving a stylus (102) on a plane (A), a phase value detector (50) for detecting a phase value (&thgr;) indicating a rotation position of the scanning rotary motion, and a contact location detector (70)for detecting a contact location of a contact portion (102A) based on a detection signal value (V) detected by the detector (103B) and the phase value (&thgr;).

摘要： A reference space includes a plurality of reference graphics. An image space is obtained by imaging the reference space. Affine transformation series are determined from the reference and image spaces for transcribing graphic cores of imaged graphics on graphic cores of reference graphics. If an affine-transformed positional error falls outside a tolerance, the reference space is divided into sub-spaces. Affine transformations and space divisions are repeated for out-of-tolerance sub-spaces until their estimations of distortion finally fall inside the tolerance.

摘要： A synchronous digital data processing system employing single-phase clock pulses comprises arithmetic and control units which are capable of completing an operation during one clock pulse period. The data processing system includes closed data paths wherein only one stage of a memory circuit capable of the same operation as a master/slave flip-flop is used as a data register in the arithmetic unit and as an address register in the control unit. In either case, during one cycle of a single-phase clock pulse, an input data is set in the memory circuit, and the output of the memory circuit is renewed in response to the input data. The output of the memory circuit is held until it is renewed in the following cycle.

摘要： A part of the output light from a semiconductor laser (1), which has a wavelength controllably variable with an injection current, is split at a beam splitter (3) and introduced into a interference optical system (5). In order to vary an optical path length difference between two light beams in the interference optical system (5) to modulate interference fringes to be obtained, AOMs (55, 56) are arranged on the two split optical paths and an EOM (56) on one of them. The interference fringes obtained from the interference optical system (5) are received at a photoreceptive device (7), and from the received signal, the phase is detected by a phase detector (8) and the phase amplitude is detected by an amplitude extractor (9). In order to stabilize the wavelength, a controller (10) feedback controls the injection current to the semiconductor laser (1) so that the phase amplitude matches to a predetermined setting.
