    Abstract: A cosmetic case includes a frame unit and a stack of trays. The trays are mounted pivotally on the frame unit, and are turnable about a single axis to move between a closed position in which the trays are aligned with each other, and an open position in which the trays are out of alignment from each other. Each of the trays lags behind an adjacent one of the trays during turning movement of the trays, and has a first engaging member, a slide rail, and a second engaging member. The first engaging member of each of the trays is slidable along the slide rail and is engageable with the second engaging member of an adjacent one of the trays for subsequent simultaneous movement therebetween.

  • Patent number: 6420226
    Abstract: A process for fabricating a buried stack capacitor structure, to be used in a one transistor, RAM cell, has been developed. The process features formation of a self-aligned, ring shaped storage node opening, formed in a top portion of an silicon oxide filled, shallow trench shape, via a selective dry etch procedure. The selective dry etch procedure in combination with subsequent selective wet etch procedures, create bare portions of semiconductor substrate at the junction of the ring shaped storage node opening and the adjacent top surface of semiconductor, allowing a heavily doped region to be created in this region. The presence of the heavily doped region reduces the node to substrate resistance encountered when a storage node structure is formed in the ring shaped storage node structure, as well as on the overlying the heavily doped region.
