A transfer conveyor system for a semiconductor inspecting apparatus using a moving magnet includes a carrier in which a semiconductor wafer or a substrate is seated and accommodated and which is transferred, an armature which is provided to be accommodated in a permanent magnet plate under the carrier, a stator which is disposed to be spaced apart from the armature, is fixedly installed on a guide rail, a sensor unit which is installed at each of two ends of each motor coil, detects whether the armature approaches, senses a variation of the magnetic field, and measures a position of the armature from speed information of the armature, and a carrier monitoring unit which is provided on the carrier and monitors the carrier to detect an abrasion degree, a damage state, or an alignment/misalignment of the carrier in real time

The invention relates to an electromagnetic actuating device (20) having at least two actuator units (1a, 1b) which are arranged adjacently in a housing (10) and which each have electrically energizable static coil means (2a, 2b), armature means (3a, 3b) mounted so as to be movable relative to said coil means, and a plunger (4a, 4b) which interacts with the armature means (3a, 3b) and which is mounted so as to be movable along axial plunger direction (S1, S2) and which has a free end portion (5a, 5b) for engagement into an actuation partner, in particular a guide groove of a camshaft, wherein the plungers (4a, 4b) of the actuator units (1a, 1b) of the actuating device (20) are preferably arranged such that the plunger directions (S1, S2) thereof run parallel to one another, and wherein the device (20) has adjustment means (6) which are integrated in the housing (10) and which serve for varying the arrangement of at least one plunger along a plane (E) perpendicular to the respective plunger direction (S1, S2).

A valve for metering a fluid, including an electromagnetic actuator and a valve needle which is actuatable by an armature of the actuator and used to actuate a valve closing body which cooperates with a valve seat surface to form a seal seat. The armature is movably guided at the valve needle in the process. A stop element connected to the valve needle limits a relative movement between the armature and the valve needle in connection with an actuation of the valve needle. At least one elastically deformable spacer element is provided between the armature and the stop element, which, during the limitation of the relative movement between the armature and the valve needle at the stop element, encloses an attenuation space provided between a front face of the armature and a stop element surface of the stop element facing the front face of the armature.

An actuator assembly including a first actuator having a first magnetically actuated plunger and a first latching plate, where the first plunger is operable to be magnetically latched to the first latching plate. The actuator assembly further includes a second actuator coupled to and axially aligned with the first actuator. The second actuator includes a second magnetically actuated plunger, a second latching plate, a sleeve positioned within and extending from the second plunger and being rigidly secured to the first plunger, and a tolerance spring wrapped around the sleeve. The second plunger is operable to be magnetically latched to the second latching plate, where latching of the second plunger causes the tolerance spring to compress and provide additional latching force of the first plunger to the first latching plate.

An electromagnetic braking device includes a brake disk, a fixed disk, an armature, a biasing member for biasing the armature, and a stator for attracting the armature. In a stator magnetic circuit member, a first yoke, a permanent magnet, and a second yoke are arranged in this order from one end to the other end of a U shape. In a rotatable state or a rotation braking state, even when the coil energization is OFF, the rotatable state or the rotation braking state is maintained. When a current of a predetermined magnitude flows through the coil in a first direction in the rotatable state, the state shifts to the rotation braking state, and when a current of a predetermined magnitude flows through the coil in a second direction in the rotation braking state, the state shifts to the rotatable state.

The present invention provides lift pin strategies with a reduced risk of causing contamination due to the up and down actuation of lift pins. The present invention provides a lift pin system that uses electromagnetic actuation strategies in order to raise and lower lift pins. The electromagnetic forces act remotely on the lift pins so that direct contact or coupling of the lift pins to actuation components is not required. This avoids contamination that otherwise would be associated with friction and associated lubricants used for mechanical actuation strategies.

An electromagnetic positioning device includes an armature member for actuating a positioning partner and movable in an armature space relative to a stationary core (30). The armature member conducts magnetic flux upon energization of a stationary coil (32). The coil has a coil support with a winding and at least one external contactable connector (46) embedded at least in sections in the core and/or surrounded by the core. The core has an end surface (34), which is planar at least in sections, for interacting with the armature member. The core and the coil are embedded in and/or surrounded by a one-piece pot-like and/or cup-like housing (38) made of a material suitable for deep-drawing in such a manner that the core rests on a membrane-like, continuous and closed base section of the housing, the base section realizing a boundary surface of the armature space.
