Abstract: A structure comprising a substrate and a component which forms involatile metal etch products is plasma etched. A structure comprising a substrate and a component which forms involatile metal etch products is provided. The structure is positioned on a support within a chamber having a first gas inlet arrangement comprising one or more gas inlets and a second gas inlet arrangement comprising one or more gas inlets. The structure is etched by performing a first plasma etch step using a first etch process gas mixture which is only introduced into the chamber through the first gas inlet arrangement. The structure is further etched by performing a second plasma etch step using a second etch process gas mixture which is only introduced into the chamber through the second gas inlet arrangement.

The power supply device has a capacitor which stores power to be supplied to the load and a processing unit in which a power supply circuit from the capacitor to the processing unit via the electrical connection device is established in a state where the power supply device is electrically connected to the electrical connection device.

Abstract: A motor according to the present invention includes an output axis, a brake for holding the output axis, a sensor for detecting an external torque applied to the output axis from outside, and a controller for decreasing or increasing the torque of the brake during operation of the brake in accordance with an increase or decrease in the external torque detected by the sensor.

Abstract: Software for a distributed streaming platform launches an application that runs on a streaming platform, in real time or near real time rather than offline. The application is structured as a directed acyclic graph (DAG) with instances of operators as nodes and streams as edges between nodes. The software receives an indication that a first instance of an operator is I/O bound. A stream connects the first instance of an operator to a second instance of another operator in a single container provided by the streaming platform. The software then transmits the indication to the application and receives a request to combine the first instance with the second instance into a single third instance of an operator. The software creates the third instance and re-initiates the stream using a recovery policy.

Abstract: A system and method for efficiently accessing replicas of a storage object. A first node may perform a find operation to determine a plurality of nodes that each store a replica of a first storage object. For each node in the plurality of nodes, the first node may establish a direct connection to the node. The first node may then access the replicas of the first storage object using the respective direct connections to the plurality of nodes. In one embodiment, the nodes may be nodes in a peer-to-peer network. Establishing a direct connection to each storage object replica may enable the first node to communicate with each node in a single hop without having to pass messages via intermediate nodes in the peer-to-peer network.

Abstract: A starter/generator mechanically coupled to a gas turbine transmission housing is disclosed. The starter/generator includes a generator with a rotor forming a field winding and a stator forming an armature, and an energizer with a stator forming a field winding and a rotor forming an armature connected to the generator field winding. The generator rotor and the energizer rotor are mounted on a common shaft with a transmission housing gear wheel, on either side of the gear wheel.

Abstract: An electrical synchronous machine, in particular for use as a drive machine in motor vehicle applications. A stator has an electrical winding arrangement for generating a rotating field. A rotor has magnetic flux generating means for generating a rotor flux with which the rotating field interacts. The rotor has a first rotor section with first magnetic flux generating means and a second rotor section with magnetic flux influencing means. It is possible to move the two rotor sections relative to one another between at least a first and a second relative position in such a way that the rotor flux provided by the rotor has a different magnitude in the two relative positions.

Abstract: A motor that delivers high force linear motion or high torque rotary motion to a moving element. The motor may include a driving brake, a driver, a holding brake and a flexible moving element. Operation of the motor may involve activating the holding brake, activating the driver to flex the moving element, activating the holding brake to maintain the position of a portion of the moving element, releasing the driving brake, and restoring the moving element to an unflexed position. The elements are arranged to provide linear motion, belt-driven rotary motion, or directly-coupled rotary motion using brakes and drivers arranged in linear or circular fashion. Drivers may be linear or rotary actuators or motors based on electrostatic, piezoelectric, magnetic, or electrostrictive properties. The brakes may be applied through electrostatic forces, magnetic forces, or mechanical gears engaged with a linear or rotary driving mechanism.

Abstract: The present invention provides an engine generator which is small in the size but high in the efficiency of power generation and a controller for the engine generator. The present invention is implemented by a power generator G driven by an engine E, a starter motor M for cranking the engine E, and a controller 4 for supplying various electric loads including the starter motor M with a driving voltage which depends on the power released from the generator G and a battery 5. The controller 4 includes an igniter 43 for feeding the ignition coil 5 in the engine with igniting energy. The controller 4 allows the source line of the igniter 43 to be supplied with a driving voltage received from a power supply line of the generator and a power supply line of the battery which are connected in parallel with each other so that the driving voltage for the igniter 43 stays not declined when the starter motor M is driven.

Abstract: An electric generation system includes an electric generator swung in a orbit and having an external contact surface for rotation of its armature by a rolling engagement with an enlarged band. The band can be turned relative to the generator within a larger diameter retaining ring so that the band is constantly radially inclined at its contact point with the generator contact surface.

Abstract: A linear synchronous motor for a high speed, ground transportation vehicle includes a linear stator assembly that is divided into sections. The stator assembly has an air gap and generates a magnetic field traveling wave therein from a constant frequency alternating current. The traveling wave has variable speeds and accelerations along different sections of the stator. A rotor assembly has a plurality of magnets forming at least one pole-pitch of a variable length. The rotor assembly is coupled to the vehicle and disposed in the air gap of the stator and runs laterally therewith, producing an attractive force between a magnetic field of the rotor and the traveling wave of the stator. The rotor has at least one magnet that includes an upper portion, a lower portion spaced apart from the upper portion, and a nonmagnetic coupler rigidly coupling the upper portion of the magnet to the lower portion. The magnetic field of the rotor propels the vehicle.
