Abstract: An equalizing mechanism of a welding apparatus connects an apparatus body and a fixed bracket, and includes a fixed member on the fixed bracket, and a pressure shaft on an apparatus body close to a bottom face of the fixed member. A cutout is at a position facing the fixed member A movable member on the apparatus body accommodates the fixed member. A restrictive member located by side faces of the fixed member and the movable member restricts relative movement thereof to a direction parallel to the pressure shaft. A driven lever is supported by a front portion of the fixed member to abut on an inner front face of the movable member at one end and abut on the pressure shaft at an other end. A spring between a back portion of the fixed member and an inner back face of the movable member presses the two members to move away from each other.

Abstract: An image sensor holder includes a frame, first and second slidable holders, first and second driving devices, first and second driving arms, and at least two elastic members. The first slidable holder is slidably mounted on the frame. The second slidable holder is slidably mounted on the first slidable holder. The first and second driving devices are separately mounted on the frame. The first driving arm is mounted on the frame and contacts to the first slidable holder and the first driving device by opposite ends thereof. The second driving arm is slidably mounted on the frame extending from the second slidable holder, and contacts the second driving device by an end thereof. The two elastic members are separately positioned between the first holder and the frame and between the first holder and the second holder.

Abstract: An image sensor holder a frame, a first slidable holder, a second slidable holder, a first and a second driving arms, a first and a second driving device and at least two restoration devices. The first slidable holder is slidably mounted on the frame. The second slidable holder is slidably mounted on the first slidable holder. The first and second driving devices are separately mounted on the frame. The first driving arm rotatably is mounted on the frame and contacts the first slidable holder and the first driving device by both opposite ends thereof. The second driving arm slidably is mounted on the frame and contacts the second slidable holder and the second driving device respectively by both opposite ends thereof. The restoration devices are respectively positioned on the frame and the first holder for restoring the first and second holders back to original positions.

Abstract: The actuator system has a external rotor motor having: (i) an internal armature configured as a stator having a set of coils wrapped around a set of arms, and (ii) an external permanent magnet rotor having a set of poles configured to rotate less than 90 degrees around the stator. The actuator system has a drive shaft configured to be rotated by the external rotor motor. The actuator system has a drive train connecting the external permanent magnet rotor to the drive shaft, and configured to provide gear ratio to the drive shaft.

Abstract: A rotational transfer connection mechanism to convert the rotational motion of one shaft to a corresponding, but different defined rotational motion in another shaft. The actuating part of the mechanism attaches to the first shaft and includes an offset tab or pin that fits into an aperture in the second part, which is attached to a second shaft, thus allowing the tab to travel through a portion of its rotation before engaging the second part. The dimensions of the aperature and tab or pin allow the shaft connected to the second part to move only a defined portion of the rotation of the first part.

Abstract: An amplifying linkage for rotational actuation between a driving shaft and a driven shaft wherein the driving shaft rotates through a first rotary angle and the driven shaft rotates through a second and different rotary angle. The driven shaft is provided with a first lever arm having a slot formed in its distal end, and the driving shaft is provided with a second lever arm having a pin protruding in a direction parallel to the axis of the driven shaft. The shafts are offset such that the pin is receivable and slidable in the slot. Rotation of the driving shaft through a first angle causes the driven shaft to be rotated through a second angle. The first lever arm is shorter than the second lever arm, so that the second angle is always greater than the first (angular rotation is amplified). The invention is particularly useful in adapting a four-pole torque motor to the actuation of an Electric Throttle Control throttle valve for an internal combustion engine.
