A recording apparatus includes a lower unit including a recording unit that performs recording on a medium, and an upper unit including a reading unit that reads a document image, the upper unit being disposed above the lower unit and being configured to open and close with respect to the lower unit. The upper unit includes an arm that maintains an open state of the upper unit by being supported by the lower unit. The lower unit has a cam groove that receives a protrusion disposed on the arm and that has a route along which the protrusion moves in a certain direction when the upper unit opens or closes. A recess that the protrusion enters and that supports the protrusion from below is disposed in the cam groove and the open state of the upper unit is maintained by the protrusion entering the recess.

A door assembly for a vehicle. The door assembly has a door body and a hinge. The hinge is connected to the door body and is rotatable about an axis of the hinge. The hinge is configured to expand along the axis from a contracted position to an expanded position when rotated in a first direction, and is configured to contract along the axis from the expanded position to the contracted position when rotated in a second direction that is opposite to the first direction. In the contracted position, the door body is in a closed, lowered position. In the expanded position, the door body is in an open, raised position.

A hold open rod includes an inner member; an outer member configured to have the inner member slide in and out of the outer member; and a noncircular dampening member arranged on the inner member. The noncircular dampening member being configured to dampen movement of at least one of the following: the inner member and the outer member.

One example of a cowling assembly for a rotorcraft includes a stationary fairing affixed to an airframe of the rotorcraft, an articulated fairing hinged on the stationary fairing for articulation relative to the stationary fairing between a closed position, a first partially open maintenance position and a second fully open maintenance position. The articulated fairing is supported in the first maintenance position by a for example gas-charged strut and is releasably locked in the second maintenance position against the stationary fairing by a locking mechanism. The locking mechanism includes a latch blade disposed on the stationary fairing and a latch arranged on the articulated fairing, wherein a latch pin engages with a hole or recess in the latch blade when the latch blade extends through a slot in the articulated fairing.

An electromechanical door supporting system for temporarily maintaining a door in an open position having: a) a housing with an electric motor in communication with a power source; b) a base plate sized to pass underneath a swinging door; c) the base plate extending away from the housing; d) the electric motor causing rotational movement in a rod extending from inside the housing, to outside the housing and over a surface of the base plate; e) a door supporting element extending perpendicular to the extended rod; and f) the door supporting element being attached to the extended rod at a proximal location and extending over the surface of the base plate to a distal end so that rotation of the extended rod causes the distal end of the door supporting element to elevate above the base plate to secure an opened door.
