摘要： A pointer measuring instrument capable of indicating “zero” on an indication panel by a pointer even if a play (backlash) is present in gears. The measuring instrument comprises a pointer reference position setting means (7a, 7b) for determining the reference position of the pointer (4). A control means (6) rotates the pointer (4) in the direction toward the reference position when a power supply to a stepping motor (2) is turned on, and performs a first drive for stopping the rotation of the pointer (4) when it receives a pointer reference position arrival signal from the pointer reference position setting means (7a). Then, the control means performs a second drive for moving the pointer (4) by a first angle from the reference position in the reverse direction away from the reference position, and performs a third drive for rotating the gear (3S) of a reduction mechanism (3) on the stepping motor (2) side by a second angle.

摘要： A contact-and-separation system includes a first roller, a second roller, and a contact-and-separation device. The first roller contacts a belt. The second roller is opposed to the first roller. The contact-and-separation device contacts or separates the belt to or from the second roller via a sheet conveyed. The contact-and-separation device includes an eccentric cam, a motor, and a circuitry. The eccentric cam is mounted on an end of a rotation shaft of the first roller. The motor rotates the eccentric cam. The circuitry controls the motor to rotate the eccentric cam to contact or separate the belt to or from the second roller via the sheet conveyed. The circuitry controls the motor to decelerate a rotation speed of the motor on contact or separation of the belt to or from the second roller between the first roller and the second roller.

摘要： A stepper motor may be controlled by a controller to provide extended revolution of a motor shaft while operating in a first mode and to allow a user to manually intervene with an intended position or rotation of the motor shaft while operating in a second mode. In some embodiments, the controller may adjust a torque applied to the stepper mode during operation of the stepper motor. The controller may reduce a torque applied by the stepper motor to a lower torque while the user intervenes with the intended position or rotation of the motor and increase the torque to a holding torque after the user intervention has ended. Thus, the controller may dynamically adjust a torque of the stepper motor in response to detection of the user intervention.

摘要： A system and method for reducing vibration in a dome camera security system is provided in which the heat produced by the motors is reduced as well. The dome camera system is equipped with an acceleration detecting circuit disposed in close proximity to the camera. The acceleration detecting circuit has an accelerometer for detecting accelerations in any of three directions (i.e., X-axis, Y-axis and Z-axis). As a vibration is induced on the camera by external forces, such as wind or traffic, the acceleration detection circuit detects accelerations indicative of the vibrations and in proportion to the magnitude of the vibration on the camera. A controlling circuit adjusts the holding current of the motors in response to the detected accelerations, thereby increasing the ability of the motors to maintain a particular camera position. When vibrations are detected to be minimal or not present, the holding current can be reduced thus reducing heat production by the motors.
摘要翻译： 提供一种用于减少半球摄像机安全系统中的振动的系统和方法，其中由电动机产生的热量也减小。 圆顶照相机系统配备有一个靠近相机设置的加速度检测电路。 加速度检测电路具有用于检测三个方向（X轴，Y轴，Z轴）中的任一方向的加速度的加速度计。 由于通过外部力（例如风或交通量）在相机上引起的振动，加速度检测电路检测表示振动的加速度并且与相机上的振动的大小成比例。 控制电路响应于检测到的加速度来调整电动机的保持电流，从而增加电动机维持特定照相机位置的能力。 当检测到振动最小或不存在时，可以减小保持电流，从而减少电动机产生的热量。
