Abstract: A view port of chemical vapor deposition apparatus for manufacturing semiconductor devices prevents heat loss in a chamber during a plasma deposition process. The view port includes a bracket protruding at the circumference of an opening in an electrode serving as a wall of a chamber of the apparatus, a transparent window pressed by the bracket against the wall via an O-ring, a pivoting cap for capping an opening in the bracket aligned with the window, and heat-insulative material and/or a heating element integral with the cap so as to be positioned close to the window when the cap is closed. The heating element can be a resistive heating wire or a warm air duct formed by a hose or the like. During the deposition process, the temperature of the window is maintained, thereby minimizing the tendency of polymer to adhere to the window.

Abstract: A connector for use in a card reader is provided. A frame is included for accommodating a card therein. The frame has an opening through which a card is inserted into the frame and removed from the frame. A plurality of connector terminals are mounted on the frame, being insulated from one another and each of the connector terminal extending from the frame to contact the card. A card sensor switch is provided for detecting complete insertion of the memory card in the frame. The card sensor switch is mounted in the inner rear portion of the frame, in an electrically insulated insulation state. A landing yoke supporting one portion of each of the connector terminals is pivotably mounted to the frame in order to minimize the sliding contact area of the memory card with the connector terminals during insertion or removal of the memory card.
