A semiconductor device of an embodiment includes a silicon carbide layer having a first plane and a second plane and includes a trench located on a first plane side and has a first region and a second region, a first silicon carbide region of an n-type, a second silicon carbide region of a p-type between the first silicon carbide region and the first plane, a third silicon carbide region of the n-type between the second silicon carbide region and the first plane, and a fourth silicon carbide region of the p-type between the second region and the first silicon carbide region; a gate electrode in the first region; a first electrode on the first plane side of the silicon carbide layer, a part of the first electrode is located in the second region and is in contact with the third and the fourth silicon carbide region; and a second electrode.

In order to improve control of a long-stator linear motor, a first measured value is ascertained in a first measurement section and a second measured value is ascertained in a second measurement section, in each case along a transport path in a movement direction. The first measurement section overlaps, in the movement direction, the second measurement section in an overlap region, and the first measured value and the second measured value represent the same actual value of a physical quantity. An operating parameter of the long-stator linear motor determined based on a deviation occurring between the first measured value and the second measured value.

A monorail vehicle includes a chassis supporting a vehicle body that includes a passenger floor, a first side wall, and a second side wall and first and second propulsion systems. Each propulsion system includes an electric motor and a drive wheel coupled to a rotor of the electric motor. Each electric motor and the drive wheel coupled to the rotor of the electric motor are positioned on both sides of an imaginary plane extension of the passenger floor. First and second shells cover portions of the first and second propulsion system. The first shell is positioned proximate to the first side wall and defines a first space between the second side wall. The second shell is positioned proximate to the second side wall and defines a second space between the first side wall.

Electrified roadway systems include a roadway, and vehicles configured to operate on the roadway. The roadway has a base, and two electrically-conductive rails mounted on the base. One of the rails is electrically connected to a source of electric power, and the other rail is electrically connected to an electrical ground. The vehicles include non-electrically-conductive tires, and an electric motor mechanically connected to, and configured to rotate at least one of the tires to propel the vehicle along the roadway. The vehicles draw electric power from the roadway via two electrical pickups. The electrical pickups are configured to move between a deployed position at which the pickups contact the respective rails, and a retracted position at which the pickups are out of contact with the rails.

According to some embodiments, a railcar comprises an interior wall and guard strips magnetically coupled to the interior wall. Each of the guard strips comprises a cushioning material for absorbing impact. The guard strips are configured to prevent an object loaded in the railcar from contacting the interior wall. The railcar further comprises protected magnetic fastening systems coupling each of the guard strips to the interior wall. Each of the protected magnetic fastening systems comprises a magnet and a rod comprising a first end and a second end. The first end is coupled to the magnet, and the second end extends through the guard strip. The protected magnetic fastening system may further comprise a cup washer coupled to the second end of the rod and secured with a fastener. The cup washer partially surrounds the fastener to restrict objects larger than the cup washer from contacting the fastener.

The present application comprises a loading gantry with at least one carriage traversable on a horizontal guide rail, in particular for the transport of workpieces between stations of a production system. In accordance with the application the loading gantry includes a media station which in at least one position of the carriage releasably can be mechanically coupled with the same in order to produce at least one media connection between the media station and the carriage.

A monorail vehicle includes two bogie assemblies supporting different ends of a chassis. Each bogie assembly includes guide wheels rotatably connected to a bogie frame, a wheel assembly for rolling along a top of a guide beam, and a drive unit. The drive unit includes an electric motor attached to the bogie frame via a mounting flange that is located within a first lateral half of the body, a brake unit, and a planetary gear assembly coupled to a rotor of the electric motor. The planetary gear assembly is located on a first side of the electric motor and the wheel assembly is mounted to an output of the planetary gear assembly. The drive unit is attached whereupon the wheel assembly may be dismounted from the drive unit in a direction of a second lateral half of the body without dismounting the drive unit from the bogie frame.

An overhead transport system includes a suspended railway and a motorized carrier configured to travel along the suspended railway. The motorized carrier includes a motorized trolley configured to move the motorized carrier along the suspended railway, chassis/beam configured to carry an object below the motorized trolley, and a bumper and deflection system configured to prevent the object from contacting another object.
