The main-drive-motor shaft (12) is coupled at least indirectly to the secondary-drive-motor shaft (22, 62) in terms of rotation, and therefore the secondary-drive-motor shaft (22, 62) is coupled to the rotor in terms of movement.
Abstract:
An internally powered sliding panel has a power source and drive train contained internally within the stiles and rails of a frame. A driven wheel is rotatably mounted on the frame and connected to the power source via the drive train. The panel may further include a lift system including a second power source, a lift mechanism, and a lift drive which are contained internally within the stiles and rails of the frame. The power sources, drive train, lift mechanism, and lift drive may be contained completely inside the stiles and rails of the frame. The movement of the panel along a fixed path, and the raising and lowering of the panel, may be regulated by a control system. The control system includes a microcontroller and sensor used to determine the position of the panel.
Abstract:
A system, method, and computer storage configured for determining period-ending positions of multiple parts movable by select actuation of corresponding active materials. The operations include receiving, from a work-source sensor, work-source input indicating a distance moved by the work source and a direction of the movement, and determining, based on the work-source input and a first and second status histories, corresponding to a first and a second part, respectively, first and second distances travelled by the parts, respectively. Operations also include calculating, based on the first and second distances determined and first and second period-starting positions, corresponding to the first and second parts, respectively, first and second period-ending positions for the first and second parts, respectively.
Abstract:
Provided is a small plug door device capable of performing an opening/closing operation and a plugging operation with a door drive mechanism for causing a force in a vehicle front-rear direction to act on a door, and further applicable also to a one-panel sliding door. A slide base 12 is installed slidably in a vehicle width direction relative to a fixed base 11. A door drive mechanism 13 for moving one door 104 in a vehicle front-rear direction via a connecting portion 19 has a drive portion 13a including an electric motor 21, a drive wheel member 13b, a follower wheel member 13c, and an endless member 13d, and is installed on the slide base 12. A guide portion 15 guides a shaft portion 14 provided on the connecting portion 19 so as to move the shaft portion 14 in a vehicle width direction. In a double-speed rail 16 in which a pinion 16c is disposed between two racks (16a, 16b), one rack 16b is connected to the slide base 12, the other rack 16a is connected to the door 104 side, and the pinion 16c is connected to the connecting portion 19.
Abstract:
The invention relates to a drive system for a gate, the gate panel thereof being guided in a guide rail on each side. A carriage is guided in one of the guide rails, and a pusher arm is joined with a hinge to the carriage and the upper edge of the gate panel. A motor is supported on the pusher arm.
Abstract:
The embodiment relates to a refrigerator. The refrigerator according to the exemplary embodiment includes: a cabinet that includes at least one storage compartment; a plurality of doors that open and close the at least one storage compartment; a plurality of operating units that are provided at each door; and a door opening apparatus that is positioned at the cabinet and opens one of the plurality of doors corresponding to the operation of the plurality of operating units, wherein the door opening apparatus includes a driving motor, a power transfer unit that transfers power of the driving motor, and a plurality of push members each of which corresponds to the plurality of doors and are connected to the power transfer unit, and when the driving motor is operated, one of the plurality of push members pushes one of the plurality of doors.
Abstract:
A driving mechanism is arranged such that at least a part is contained within a space corresponding to the external shape of a driving motor, that is, within a space corresponding to a distance in the radial direction of the driving motor. The driving mechanism comprises a pinion, a transmission gear, a ring gear that forms a fixed axis, and a carrier. The pinion is connected to a rotary shaft of the driving motor. The transmission gear has a disk gear portion that meshes with the pinion, and a sun gear portion that is located on the same side as the pinion with respect to the disk gear portion. The carrier has a planet gear and rotates with a drum.
Abstract:
A door closer with an automated calibration mode is disclosed. The door closer that can be self powered and includes a control unit to intelligently control a valve within the door closer to vary the operating characteristics of the door closer as needed. The control unit includes a calibration mode that can be invoked to match the control unit to the mechanical door closer assembly. A plurality of positional values being output encoders coupled to an arm of the door closer and the motor for the valve can be determined. The positional values from the encoders and the positions that they indicate can then be stored in a memory within the controller for use during normal operation of the door closer.
Abstract:
A step unit includes: a step member which is provided with a pair of lower rails extending in an opening and closing direction of a slide door of the vehicle; and a rail plate member which is provided to a cutout formed in a part of either of the lower rails and which continuously connects the lower rails in the opening and closing direction. The step member is molded using a resin material and is provided with an insertion hole which vertically penetrates through the step member at a position corresponding to the cutout; and a support extension section which is extended from a side end of the cutout of the lower rail. The rail plate member is mounted to the step member by being inserted so as to penetrate through the insertion hole from above the step member.
