    摘要: A composite membrane comprises a substrate made from a polymer selected from copolymers and homopolymers of ethylenically unsaturated nitriles, which substrate has preferably first been treated with a pore protector in absence of curing agents and catalysts therefor, prior to applying as the final coating a silicone layer, which is crosslinked. The pore protector, which may be, for example, a hydroxy-terminated polysiloxane, particularly a silanol-terminated polysiloxane, serves the dual purpose of preventing the pores from collapsing, when the support is dried during the curing of the silicone layer, and of preventing passage of the coating material deeply into the pores and thus also preventing an undue reduction of the flux of the finished coated membrane. Such composite membranes include solvent stable membranes which swell to an extent of no more than about 10% when immersed in various organic solvents, and their mixtures with each other and/or water.

    摘要: An electronic component such as a capacitor includes a substrate having first and second principal surfaces, a dielectric layer overlaying the first principal surface of the substrate, a first electrode, and a second electrode. There is a passivation layer overlaying the first and second electrodes, a first opening being formed in the passivation layer over the first electrode and a second opening being formed in the passivation layer over the second electrode. A first bottom electrode termination is positioned in the first opening and a second bottom electrode termination is positioned in the second opening. The first bottom electrode termination is electrically connected to the first electrode and the second bottom electrode termination is electrically connected to the second electrode. A standoff is positioned between the first bottom electrode termination and the second bottom electrode termination and attached to the passivation layer to thereby provide support for the electronic component when mounted. The standoff provides resistance to tilting.
