Abstract: A stacked connector includes a base dock connecting to an electric circuit. The base dock has an insert member mounted thereon. The insert member includes at least two insert slots and is encased by a metal shell from outside. The rear side of the insert member is coupled with a transfer connection circuit. The base dock has connection terminals directly connecting to the electric circuit. The connection terminals in each insert slot are extended to the rear side of the insert member to connect to the transfer connection circuit. Thereby the length of the connection terminals may be reduced to lower the cost and enhance the structural sturdiness and reduce interference between the terminals.

Abstract: Non-asbestos ion-polymer composite friction materials show high heat resistance and low wear, being especially useful for friction elements in brake shoes or blocks in automobiles and industrial machines. The non-asbestos ion-polymer composites are basically composed of a polyacrylonitrile fiber and an ion-polymer used as binder matrix. An optional friction modifier can be added to include, e.g., carbon, graphite and/or MoS.sub.2, etc. The ion-polymer is polymerized from alpha, beta-unsaturated-gamma-carbonyl monomers, e.g., acrylic acid, or esters thereof or their comonomers, directly onto the solid surface of divalent metal compounds, e.g., Ca, Sr, Ba, Zn salt(s) and/or oxide(s).
