Provided is a small plug door device having a slide base is installed slidably in a vehicle width direction relative to a fixed base. A door drive mechanism for moving one door in a vehicle front-rear direction via a connecting portion has a drive portion including an electric motor, a drive wheel member, a follower wheel member, and an endless member, and is installed on the slide base. A guide portion guides a shaft portion provided on the connecting portion so as to move the shaft portion in a vehicle width direction. In a double-speed rail in which a pinion is disposed between two racks, one rack is connected to the slide base, the other rack is connected to the door side, and the pinion is connected to the connecting portion.

The museum showcase comprises a casing with at least one open side, a sliding door for closing the open side of the casing, a guide system to allow the horizontal displacement of the sliding door with respect to the casing, and an actuation system to cause the displacement of the sliding door on the guide system. The actuation system comprises a rack, integral with the sliding door and extending in the direction of its width, two drive pinions rotatably mounted on the casing and in meshing engagement with the rack. The two pinions are arranged spaced apart from each other in the direction of the width of the open side of the casing. It follows a very wide opening of the showcase.

An anti-theft security system for business entryways that is a housing assembly with at least one sidewall. An entrance in the sidewall is located opposite an exit so a person can move straight through with the sidewall including at least one transparent portion. A sensor assembly on the housing assembly is designed to detect electronic tags on products. Separate entrance and exit retractable doors are opened or closed independently or simultaneously in response to the sensor assembly. At least one control unit and at least one electronic motor assembly is electrically or wirelessly coupled to the sensor. The electronic motor is also coupled to the entrance and exit retractable doors, the doors slidably movable along a track assembly disposed internally, externally, or within the sidewall to open or close the doors. At least one alarm is electrically coupled to the sensor assembly. A control switch controls which doors are closed when a sensor detects a tag and a release actuator may open doors manually.

A sliding door has a brake element for braking the door leaf, an adjustment device configured to switch the brake element over from a braking position, in which the door leaf is being braked, to a release position, in which the door leaf is not being braked, and from the release position to the braking position, and a motor drive unit which is configured to cooperate with the adjustment device and to allow the brake element to be adjusted.

A drive cable for actuating a vehicle element movable relative to a vehicle body is provided, the drive cable having a cable body having a cable core around which a coil following a helical line is coiled, the coil serving to engage with a gear wheel, the cable body being provided with a cable sheath. The cable sheath is glued to the coil.

A control apparatus includes a first controller which controls an operation of a door of a railway vehicle, a second controller capable of controlling the operation of the door, and a diagnosis tester. The diagnosis tester performs a diagnosis related to an abnormality in the second controller when performing a start process which accompanies turning on power of the control apparatus.

A system and portable device are provided for opening and closing sliding doors associated with conventional sliding doors as used in residences and businesses. The portable sliding door device attaches to a sliding door via a bracket, and moves along the same track used by the sliding door. The sliding door device can be initiated to move the sliding door to the open position through remote control, voice-activation, and proximity transmitters. The sliding door device can communicate with wireless routers and be remotely controlled and monitored by computers, netbooks and cell phones. The sliding door device has safety features, including cameras and speakers to ward off attempted break-ins.
