摘要： The disclosure provides system, computer readable medium, and method for producing a hydroxyl radical. A plasma of a plasma gas is formed, via a controller, using a remote plasma source fluidly coupled to a gas inlet conduit coupled to a first nozzle of a processing chamber. A first gas radical is produced by flowing a first gas from a first gas source through the remote plasma source. The first gas radical is introduced into the processing chamber using the gas inlet conduit coupled to the first nozzle. A second gas from a second gas source is introduced using a plurality of second nozzles fluidly of the processing chamber. An oxidation radical is produced by mixing the first gas radical and the second gas in the processing chamber.

摘要： To provide: a silicon nitride sintered body having excellent mechanical property, in particular fracture toughness, and having long lifetime of a product into which the silicon nitride sintered body is processed; a rolling element using the silicon nitride sintered body; and a bearing. The silicon nitride sintered body contains a rare earth element and an aluminum element. The silicon nitride sintered body contains 6-13 wt % of the rare earth element in terms of oxide, and 6-13 wt % of the aluminum element in terms of oxide, relative to the total weight of the silicon nitride sintered body. The silicon nitride sintered body contains an inclusion (I) in a surface layer portion that is a region within 2 mm from a surface of the silicon nitride sintered body. A ratio of a total sectional area of the inclusion (I) to a total sectional area of the surface layer portion is 0.05% or more.

A second aspect of the invention relates to a device, in particular for performing the above process, comprising at least the following components: —a vessel for receiving an electrostatically stabilized suspension of particles, —a charge injector, in particular including one or more electrodes or a source of high-energy charged particles, —means for moving the electrode and/or the vessel in the x, y and z directions, —a counter electrode arranged in the vessel for a contact with the suspension of particles, —one or more sensors for determining geometrical and physical parameters within said vessel. In one preferred embodiment, said device further comprises a means for directing a beam of gas-ionizing radiation, in particular a laser beam, to a predetermined position within the vessel.

摘要： A force-transmitting assembly includes a metal shaft having at least two longitudinally-extending grooves defined in an outer surface, and a metal hub having at least two longitudinally-extending grooves defined in an inner surface that surrounds the outer surface of the shaft. A plurality of discrete parts is disposed in the at least two longitudinally-extending grooves of the shaft and the hub in an interference-fit manner so as to transmit a torque from the shaft to the hub. Each of the discrete parts is composed of at least 50 mass % of technical ceramic selected from Si3N4, SiAlON, Al2O3, ZrO2, or a mixture of two or more of Si3N4, SiAlON, Al2O3, and ZrO2.
