    摘要: In a stepping motor including two stators and a rotor having two magnets, three dimensional relations, specifically a relation of Lm/Ls, another relation of d/2Lm, and still another relation d/D, are optimally determined while satisfying their respective ranges: 0.35≦Lm/Ls≦0.45; 0.77≦d/2Lm≦1.10; and d/D≦0.45, where Lm is the axial dimension of the magnet, Ls is the axial dimension of the stator, d is the outer diameter of the magnet, and D is the outer diameter of the stator, whereby a space for accommodating a sufficient number of coil turns is secured maximally in the stator, and the inertia and the cogging torque of the rotor are reduced maximally, which leads to producing the highest possible torque at a high rotation speed range required.

    摘要: An image processing apparatus performs color conversion processing on an input image. The image processing apparatus includes a block pallet conversion unit, a first color converting unit and a restoration unit. The block pallet conversion unit converts the input image in units of blocks into (i) pallet color information including pallet colors number of which is less than pixels included in one of the blocks and (ii) selection information used to select one of the pallet colors for each pixel. The first color converting unit performs color conversion on the pallet color information obtained by the block pallet conversion unit. The restoration unit selects for each pixel, based on the selection information, one of the pallet colors of the pallet color information, which is color-converted by the first color converting unit, to restores an image.

    摘要: In a motor comprising a stator assembly and a rotor assembly housed inside the stator assembly, a bobbin is structured to be oval-cylindrical in its radial cross section, rather than circular-cylindrical, such that a body section of the bobbin is composed of four continuous walls, two of which are formed of flat plates oriented perpendicular to the minor axis of the oval and disposed opposite to each other in parallel, and the other two of which are formed of outwardly arced plates oriented perpendicular to the flat walls and disposed opposite to each other in a symmetric manner. Pole teeth are provided only at portions corresponding to the arced walls to thereby reduce the dimension between the flat walls for downsizing while allowing an increased number of turns of a magnet wire wound around the bobbin.

    摘要: A claw-pole stepping motor with rotor, including a vibration reducing magnet. Vibration in the axial direction is suppressed by having a correction force, which overcomes a force produced by a vertical motion caused when the rotor is pulse-driven, and keeps the rotor attracted to one side. The corrective force is generated between an index generating magnetized portion in a lower area of the rotor and a soft magnetic material base. Magnetic flux leakage produced by the excitation of the stator coils of the motor is suppressed by providing a shield ring made of a magnetic material on an inner side of the rotor magnet, which minimizes the magnetic flux flowing from the coils to the revolving shaft, and noises on the recording and reproducing head are thereby greatly reduced.

    摘要: Salient poles made from soft magnetic steel plates have tip sections of approximately the same length as a rotor magnet. The salient poles are constructed with laminations in the circumferential direction, with axial dimensions adjusted with respect to the circumferential dimensions determined by the constraints of the winding to allow winding sections with a minimum required cross-sectional area so that magnetic saturation does not occur. These winding sections are inserted into coils wound with magnet wire, and press fitted into the stator which makes the magnetic circuit with the salient poles and forms the armature.

    摘要: To reduce as much as possible the motor vibration due to the effect of harmonic components contained in the induced electromotive force waveform induced in the armature coil. In a motor structure, the pole tooth shapes of one pole tooth and the corresponding pole tooth thereto constituting one phase are made different from each other by changing their areas or amounts of skew, whereby the third harmonics caused by variations in the magnetic fluxes interlinking with these pole teeth are caused to cancel each other. Thus, the rotational vibration which has hitherto been a problem can be reduced and, further, the accuracy of the rotor movement can be improved without lowering the dynamic torque characteristic of the motor.
