Abstract: An XY-axes table having a base, a plurality of linear guiding apparatuses, a stage, an X-axis drive linear motor and a Y-axis drive linear motor. The linear motor include an armature and a movable element relatively movable with respect to the armature. The linear motor further includes first magnetic pole teeth rows which are magnetically connected to a first magnetic pole of the armature and are arranged so as to be separated into a first stage and a second stage in a substantially vertical direction to a moving direction of the movable element. Second magnetic pole teeth rows which are magnetically connected to a second magnetic pole of the movable element are arranged so as to be separated into a first stage and a second stage in a substantially vertical direction to the moving direction of the movable element.

Abstract: A fluid transfer apparatus utilizes a linear motor including a movable element in which magnetic poles are provided at a predetermined pitch along a moving direction, magnetic pole teeth provided in upper and lower portions of the movable element at a predetermined pitch along a moving direction of the movable element and so as to oppose to each other via the movable element, and a coil, wherein adjacent magnetic pole teeth and opposing magnetic pole teeth among the magnetic pole teeth form different poles.

Abstract: A mesh type automatic transmission is equipped with a plurality of shift gears arranged to rotate freely to an output shaft for providing driving force to the wheels. Cogged clutches 12, 15 engage with the output shaft. Counter shift gears corresponding to each speed are fixed to a counter shaft rotated by the rotation of an input shaft and mesh with the shift gears for performing automatic shifting by controlling engagement of one of the cogged clutches with the voluntary shift gears determined from the accelerator command value and the vehicle speed. An assist mechanism transmits rotational force of the input shaft to the output shaft via the assist shaft which rotates from the rotation of the counter shaft when no cogged clutch of the plurality of cogged clutches is engaged with any of the plurality of shift gears occurring during switching when an engaged cogged clutch of the plurality of cogged clutches is disengaged and one of the cogged clutch of the plurality of cogged clutches is to be engaged.

Abstract: A linear motor and a method of producing the linear motor are provided to reduce a leak magnetic flux flowing between an armature and a moving element to reduce a one-direction magnetic attraction force generated between the armature and the moving element. The linear motor includes the armature having a core formed of a magnetic body and a winding wound around the core, and the moving element supported so as for the moving element to move relatively to the armature via a gap, magnetic pole teeth disposed above and below the moving element, disposed at predetermined pitches along a moving direction of the moving element and disposed opposite to each other via the moving element, and a winding for exciting the magnetic pole teeth such that adjacent and opposite magnetic pole teeth have different magnetic poles, and the moving element is reciprocated relatively to the armature by exciting the winding according to a predetermined control circuit.
