A motor module includes: a motor; a driving unit; a control unit; a memory; and a communication unit. The control unit executes: receiving parameter information specialized for a vehicle-mounted device by the communication unit from a management module, and storing the parameter information in the memory; in a case where the parameter information is stored in the memory, driving the motor by the driving unit to operate the vehicle-mounted device so that the motor outputs a predetermined torque based on an operation signal input from an outside for operating the vehicle-mounted device and the parameter information; and in a case where the parameter information is not stored in the memory, driving the motor by the driving unit for a certain period of time and then stopping the motor to inch the vehicle-mounted device so that the motor outputs a maximum torque, based on the operation signal.

A system for transferring torque with zero lash from a driver to a driven object is provided. The system includes a shaft disposed about a rotational axis and a hub defining a bore that receives the shaft. The shaft and hub are each configured for coupling to one of the driver and driven object. The shaft defines a flat on a radially outer surface and the hub defines a flat on a radially inner surface opposing the flat in the shaft. In one embodiment, the shaft includes a threaded bore and the hub includes an aligned through bore. Rotation of a threaded fastener in the bores draws the flat into engagement. In another embodiment, the hub includes a threaded through bore. Rotation of a fastener extending through the bore and engaging the shaft diametrically opposite the flats urges the flats into engagement.

A flat-type ventilation door-window structure includes a frame (1), a first movable sash (2) and a second movable sash (3). The first movable sash (2) and/or the second movable sash (3) can slide up and down in an opening (11) of the frame (1). A first guide device (300) and a second guide device (400) being respectively provided between the first movable sash (2) or the second movable sash (3) and the frame (1). The first guide device (300) and the second guide device (400) can guide the first movable sash (2) or the second movable sash (3) to change the sliding path. The flat-type ventilation door-window structure can block outdoor sound, rain and air, and improve sound insulation, water tightness and air tightness.

An economical bi-parting door assembly for an aisle between two rows of data center IT racks is disclosed which is easy to assemble, has no floor track or leveling requirements, and an overhead suspension and drive assembly for the left and right door assemblies. Guide ribs and channels can be provided for the door leaves at the lower portions of the leaves and mating features are placed on the leading faces of the leaves. Some features are designed to work specifically with a containment system frame for server cabinets.

A vehicle door includes a door panel slidably operable between a secured position within a door aperture and a staging position partially distal from the door aperture. A latch is engaged with a striker path during operation of the door panel between the secured and staging positions, and is selectively disengaged from the striker path to define open and closed positions of the door panel when the door panel is in the staging position.

A mechanism for conjointly operating a plurality of gate assemblies mounted on a hopper car having an elongated car body with sides and ends, and a bottom defining a discharge area comprised of a plurality of discharge openings. Each gate assembly includes a slide door arranged in operable association with one of the discharge openings. The mechanism operates the slide door on all the gates conjointly relative to each other. Methods for controlling the gravitational discharge of material from a hopper car are also disclosed.
