摘要： A direct-current motor is provided with an armature, which includes a core and coils, a commutator, which has segments, a first, second, and third brushes, and a pair of magnets. The core includes teeth, which form teeth groups. The tooth located at the most advancing end in a teeth group in the rotation direction of the armature is the most advancing tooth. Each coil is wound about one of the teeth groups. One of the magnets includes a reverse flux portion. When the third brush starts to establish a short circuit between an adjacent pair of the segments during the rotation of the armature, the most advancing end of the most advancing tooth in the teeth group that corresponds to the coil connected to the pair of the segments starts circumferentially overlapping the reverse flux portion. This suppresses the interference caused by a short circuit established by the third brush.

摘要： When one of armature coils is in a beginning of a commutation process, a center line of a trailing end tooth of a corresponding group of teeth, around which the one of the armature coils is wound, is generally aligned with a corresponding boundary between magnets. When the one of the armature coils is in an end of the commutation process, a center line of a leading end tooth of the corresponding group of the teeth is generally aligned with another boundary between the magnets.

摘要： The armature of a direct-current motor is formed by an armature core and armature coils. The core includes teeth, which are arranged at a pitch of a predetermined angle. The coils are wound about every group of selected teeth of a predetermined number. Two magnets face each other with the armature in between. Each magnet includes main portion, an extended portion, which extends from the main portion, and a first weak flux part. The first weak flux part is located in the vicinity of the border of the extended portion and the main portion. The first weak flux part extends along one pitch of the teeth. The flux of the first weak flux part gradually increases along the rotation direction of the armature. The motor also includes a commutator, which has segments. The segments are connected to each coil. A pair of brushes can contact each segment. The brushes supply current to the coils through the segments. During commutation, each brush establishes a short circuit in an adjacent pair of the segments, thereby changing the direction of current flowing through the coil. When commutation is started, the advancing end of the first tooth in one of the teeth groups, the first tooth being located at the most advanced position in the group in the rotation direction of the armature, is aligned with the first weak flux part of one of the magnets.

摘要： A direct current motor is comprised of an armature, magnets arranged to face each other through the armature, a commutator and brushes. The armature has a core and a plurality of coils wound on the core. Each magnet has a main part and an extension extending form the main part. The main part has an angular interval which corresponds to an interval of winding each coil, so that the extension is positioned outside the coil in the circumferential direction. During the commutation period of the coil, that is, during shorting of the coil by the brush, the amount of magnetic flux passing through the coil is changed by the extension of the magnet. Thus, an induction voltage is generated in the coil to counteract to a reactance voltage of the coil.

摘要： An image processing device includes a first encoding processing portion to perform first encoding processing according to a first compression method for compressing multilevel image data and a second encoding processing portion to perform second encoding processing according to a second compression method for compressing binary image data. A determination portion determines whether an image made up of acquired image data is a monochrome image. A data volume estimating portion makes an estimation between a first data volume when image data forming the monochrome image is compressed by the first encoding processing and a second data volume when the image data is compressed by the second encoding processing as to which data volume becomes smaller. A file creating portion creates a data file from image data that has the smaller volume.
