  • Patent number: 9603288
    Abstract: A housing for electronic/electrical components includes an inner panel and an outer panel, a strip of metal plate, and a strip of shape memory material. The inner panel and the outer panel are disposed parallel to each other to define an internal space. The strip of metal plate extends from an inner surface of the outer panel. The strip of shape memory material extends from an inner surface of the inner panel and is attached to or detached from the metal plate on the outer panel while changing into an original straight shape or a bent shape according to a temperature variation. When the temperature increases beyond a first transition temperature, the shape memory material straightens to form a heat transfer path. When the temperature falls below a second transition temperature, the shape memory material bends and is separated from the metal plate to interrupt the heat transfer path.

  • Patent number: 9296871
    Abstract: The present disclosure provides a high heat radiation composite material including a hybrid filler comprising expanded graphite filled with expandable polymeric beads, and a fabrication method thereof. In the method, a dispersion solution is prepared by dispersing expandable polymeric beads in ethanol. Expanded graphite is immersed in the dispersion solution, and heat-treated to remove ethanol, thereby producing the hybrid filler. The hybrid filler is dispersed into the matrix polymer via an extrusion/injection process, thereby producing the composite material.

  • Publication number: 20150382442
    Abstract: This disclosure describes systems, methods, and apparatus for pulsed RF power delivery to a plasma load for plasma processing of a substrate. In order to maximize power delivery, a calibration phase using a dummy substrate or no substrate in the chamber, is used to ascertain a preferred fixed initial RF frequency for each pulse. This fixed initial RF frequency is then used at the start of each pulse during a processing phase, where a real substrate is used and processed in the chamber.
