摘要： A motor control device may include a position command output means, a first subtraction means that calculates and outputs a position deviation, a position control means, a second subtraction means that calculates and outputs a position deviation, a speed control means that outputs a torque command, a limiter limits the level of the torque command, a motor drive means, and a voltage fluctuation detection means. When the voltage fluctuation detection means detects that the voltage of said power source has dropped below a predetermined reference level, either the position command output means varies the position command so as to reduce the rotational speed of the motor and/or said position control means limits said speed command to be output.

摘要： A stator is provided. In the stator, abutting surfaces are formed on both ends of each of outer peripheral parts constituting an outer peripheral ring section of a stator core, and the abutting surfaces of circumferentially adjoining outer peripheral parts are abutted together. Angles formed by first abutting surfaces, that is, an abutted surface which is formed along a joint located at one of the boundaries of the outer peripheral parts in the circumferential direction, and respective center lines of salient pole parts which connect with outer peripheral parts are smaller than an angle formed by each second abutted surface, that is, an abutted surface other than that of the first abutting surfaces, and a center line of a salient pole part which connects with the outer peripheral part on which this second abutted surface is formed.

摘要： A card reader may include a fixed body having a card moving passage, a pulling-out prevention member supported by the fixed body and structured to turn between a closing position and an open position, and structured to prevent pulling-out of the card at the closing position, a first urging member which urges the pulling-out prevention member toward the closing position, a lock member to prevent turning of the pulling-out prevention member toward the open position, and a lock member drive mechanism. The lock member may be driven by the lock member drive mechanism and swung so as to be switched from one of an unlocking attitude permitting turning of the pulling-out prevention member toward the open position and a locking attitude interfering with the pulling-out prevention member and preventing turning of the pulling-out prevention member toward the open position to the other of the unlocking attitude and the locking attitude.

摘要： An optical unit with a shake correction function may include a movable module holding an optical element; a fixed body; a support mechanism swingably supporting the movable module at a midway position in an optical axis direction; and a shake correction drive mechanism to swing the movable module. The movable module may include an optical module which holds the optical element; and a weight provided on one side of a front side and a rear side in the optical axis direction of the optical module, the weight being configured to shift a gravity center position of the movable module to a support position side of the support mechanism relative to a gravity center position of the optical module in the optical axis direction. An end face of one side of the weight may be formed in a flat face which is perpendicular to the optical axis direction.

摘要： A motor in which a stator core is positioned in a case; a motor device equipped with the motor; and a pointer type display device are provided. Specifically, in a motor, a stator core is equipped with a round hole and an elongated hole, and positioning parts that correspond to the round hole and the elongated hole are formed in a first case. The positioning part is equipped with a cut-out part, guide parts disposed to either side of the cut-out part, and a projecting part positioned to the outer peripheral side of the cut-out part. The elongated hole is formed in a protruded part that protrudes to the outer peripheral side from a connecting part of the stator core. The stator core is positioned by fitting the round hole into a support shaft of a first gear, and fitting the projecting part of the positioning part into the elongated hole.

摘要： A wide angle lens includes a first to a third lenses, a diaphragm, a fourth to a sixth lenses disposed in order from an object side. The fourth lens is a glass lens, and the second lens, the third lens, the fifth lens and the sixth lens are plastic lenses. The fifth lens and the sixth lens constitute a cemented lens. When a center curvature radius on an image side face of the fourth lens is “R42” and a focal length of an entire wide angle lens is “f0”, the center curvature radius “R42” and the focal length “f0” satisfy the conditional expression: 2×f0≦|R42|≦5×f0. When a center curvature radius on an object side face of the fourth lens is “R41”, the center curvature radii “R41” and “R42” may satisfy the conditional expression: |R41|≧|R42|.

摘要： An optical unit with a shake correction function may include a movable module holding an optical element, a support body including a body part surrounding the movable module, a gimbal mechanism including a movable frame having elasticity and configured to swingably support the movable module between the movable module and the support body, a spring member connected to the movable module and the support body for holding posture of the movable module, and a shake correction drive mechanism configured to swing the movable module. When a natural vibration frequency of the movable frame is “fa”, a natural vibration frequency of the spring member is “fb”, and a vibration frequency band of a movable body on which the support body is mounted is “fw”, the natural vibration frequency “fa” and the natural vibration frequency “fb” are shifted from the vibration frequency band “fw”. Further, it may be preferable that a difference between the natural vibration frequency “fa” and the natural vibration frequency “fb” is set to be 135 Hz or more.
