Abstract: The present invention relates to an electromagnetic shielding device. Further, the present invention relates to a arrangement for electromagnetic shielding of two adjacent relatively movable members having opposed surfaces with a space therebetween. The electromagnetic shielding device includes a resilient cap portion having a center portion and a plurality of segments extending radially outwardly therefrom.

Abstract: Formed metal electrical wiring boxes possess integral wiring device mounting members which permit the facile push-insertion of the wiring device mounting screws, but which firmly engage the mounting screws once tightened down. The mounting members comprise a flat portion attached to each endwall of the wiring box and formed at right angles to the endwalls. Opposed leg portions are attached to the flat portion, and are folded downwardly along the box endwalls. The leg portions terminate in opposed foot portions spaced apart from one another by a distance less than the diameter of the wiring device mounting screw. A mounting screw inserted through an aperture in the flat portion and between the opposed leg portions contacts the opposed foot portions forcing the leg portions apart to permit the push-insertion of the screw. Turning the mounting screw draws the opposed foot portions upward, forcing them against the screw threads to firmly engage the screw.

Abstract: An electronic part mounting construction, such as a transistor package or a substrate for a resin mold device, has a substrate for mounting an electronic part on a principal surface, at least one metallized layer deposited on the principal surface and soldered to the electronic part thereon, another metallized layer continuously extended from the at least one metallized layer in a direction perpendicular thereto, and an insulator layer deposited on the other metallized layer. The other metallized layer is provided on a side surface of a wall member or the substrate.

The contact finger(s) is/are thus effectively embedded in the sealing compound, and locked in position when it sets, so giving a secure contact as well as an effective fluid-tight seal.

Abstract: A filter for use in combination with a cathode ray tube screen to transmit light and absorb other types of energy comprises a translucent plastic substrate onto which is applied a wire mesh impregnated with a thin layer of a bonding agent which constitutes one surface of the filter.
