Abstract: Shock mounting and enhanced conductive cooling of electrical components on printed circuit cards are achieved by mounting the non-component surface of the circuit card to a cold plate with a viscous, heat conductive, electrically insulating material sandwiched between the cold plate and circuit card. The cold plate may be an aluminum plate with a thermally conductive, electrcially insulative anodized surface. Typically, the cold plate is attached to a chassis of electrical equipment, or to a similar heat sink.

Abstract: A stage for holding a slide under a microscope in a microscope system is disclosed. The stage includes a movable support member, a slide holder for engaging a slide secured to the movable member. The slide holder is movable with the support member so that a slide held thereby is movable with respect to the optical axis of the system. A condenser disposed in the optical axis of the system is provided. The slide is held and supported by the slide holder and is slidably supported by the condenser so that the plane of the slide in the optical axis of the microscope system remains substantially fixed longitudinally of the optical axis as the slide is moved transversely with respect thereto.
