Patent number: 9514872Abstract: An electromagnetic actuator includes a plunger, an armature, and a coil. The plunger is moveable between a first position and a second position. The armature includes a first armature portion proximally disposed about the first position, and a second armature portion proximally disposed about the second position. The coil is proximally disposed with the first armature portion and, when energized, is configured to generate a magnetic field. The magnetic field causes the plunger to move toward the first position by a magnetic flux through a magnetic circuit. The magnetic circuit includes the first armature portion, the plunger, a main air gap, and a variable air gap. The main air gap and variable air gap are between the first armature portion and the plunger. The main air gap diminishes as the plunger moves toward the first position. The variable air gap enlarges as the plunger moves toward the first position.Type: GrantFiled: December 19, 2014Date of Patent: December 6, 2016Assignee: General Electric CompanyInventors: Vandana Rallabandi, Srinivas Satya Sai Mallampalli, Ravindra Shyam Bhide

Publication number: 20130192761Abstract: A substrate processing system for processing multiple substrates is provided and generally includes at least one processing platform and at least one staging platform. Each substrate is positioned on a substrate carrier disposed on a substrate support assembly. Multiple substrate carriers, each is configured to carry a substrate thereon, are positioned on the surface of the substrate support assembly. The processing platform and the staging platform, each includes a separate substrate support assembly, which can be rotated by a separate rotary track mechanism. Each rotary track mechanism is capable of supporting the substrate support assembly and continuously rotating multiple substrates carried by the substrate carriers and disposed on the substrate support assembly. Each substrate is thus processed through at least one shower head station and at least one buffer station, which are positioned at a distance above the rotary track mechanism of the processing platform.Type: ApplicationFiled: January 30, 2013Publication date: August 1, 2013Inventors: Joseph Yudovsky, Ralf Hofmann, Jeonghoon Oh, Li-Qun Xia, Toshiaki Fujita, Pravin K.
