Coil block manufacturing method
A coil block manufacturing method of winding a wire around a coil core in which a core portion is provided between a first attachment portion and a second attachment portion, includes: a first step of fixing one end of the wire; a second step of, in a state of holding the first attachment portion of the coil core by a first chuck to expose the whole core portion, winding the wire around an end of the core portion; and a third step of, in a state of holding the second attachment portion of the coil core by a second chuck to expose the whole core portion, winding the wire around the whole core portion, to form a coil portion.
MOTOR DEVICE AND POINTER-TYPE DISPLAY DEVICE
In the case of this motor device, tip parts (230) of first protrusion sections (23), which hold a stator core (60) from inside of a first case (21) in the direction of a rotational center axis line (LO) in conjunction with a second case (22), are tapered toward the stator core (60). Also, tip parts (240) of second protrusion sections (24), which hold the stator core (60) from inside of the second case (22) in the direction of the rotational center axis line (LO) in conjunction with the first case (21), are tapered toward the stator core (60). Thus, when the protruding lengths of the first protrusion sections (23) and the second protrusion sections (24) are set somewhat long in advance, the first protrusion sections (23) and the second protrusion sections (24) hold the stator core (60) in a state in which the tip parts (230, 240) are crushed.

Electromechanical Limited Rotation Rotary Actuator and Method Employing Segmented Coils
An electromechanical rotary actuator includes a stator having teeth extending inwardly from an inner wall surface, wherein free ends of each tooth form an aperture dimensioned for receiving a rotor, the free ends forming a gap therebetween. A segmented set of electrical coils extends around each tooth, wherein each coil of the segmented set has a thickness sufficient for passing through the gap between the first and second teeth. Electrically insulating tabs extend into an opening around each tooth carrying the segmented set of coils. The tabs maintain each of the coils within the segmented set in a spaced relation to the stator. When fabricating the actuator, each of the coils are fabricated and individually placed around a tooth with each coil having a thickness and breadth for optimally packing the stator.
