摘要:
A CMOS FET master slice integrated circuit (20) of the gate-array type implemented in a semiconductor logic chip, comprises a plurality of core cells (CELL1, CELL2, . . . ) arranged adjacent one another on a repetitive basis in a row direction to form horizontal stripe shaped functional gate region (21) of a determined height (H). Each core cell (e.g., CELL1) is comprised of four different sized devices: one small and one large NFET (N1.1, N2.1), thus one small and one larger PFET (P1.1, P2.1), that are disposed in a column direction. The NFETs have separate gate electrodes (GN1.1, GN2.1) to define individual devices, while the PFETs have preferably a common gate electrode (GP1) to define a single device. The relative size of NFETs and PFETs have been optimized to provide the required functionality to the latches and to ensure the balanced rise and fall delays in a maximum of basic logic circuits of the chip. As a result, the use of such core cells, allows that complex logic functions, such as latches, can be implemented in gate arrays that have a density and performance comparable with standard cell circuits. In addition, the use of these core cells also permits optimization of other basic logic circuits (INV, NOR, . . . ) that are used in critical logic paths and clock distribution trees, where balanced delays are highly desirable.
摘要:
A sash frame is provided having a first mounting surface for a first glazing pane and a second mounting surface for mounting a second glazing pane substantially parallel to the first glazing pane. The first and second mounting surfaces are spaced apart to provide an insulating space between the glazing panes. An evacuation opening is provided in communication with the insulating space. The first glazing pane is adhesively mounted to the first mounting surface and the second glazing pane is adhesively mounted to the second mounting surface. Air is allowed to exhaust through the evacuation opening as the insulating space is formed between the glazing panes. A vacuum is drawn from the evacuation opening to draw the first and second glazing panes closer together after the panes have been mounted on their respective mounting surfaces. Mounting of the glazing panes may also be facilitated using a roll press.
摘要:
An integrated multipane window sash is fabricated from a sash frame having an inside perimeter. An adhesive material is applied to the inside perimeter. The adhesive material has sufficient stiffness to function as a mounting structure for glazing panes, and may also function as a spacing structure. A first glazing pane is mounted to a first side of the adhesive mounting structure. A second glazing pane is mounted to a second side of the adhesive mounting structure or to a separate adhesive mounting structure. The adhesive mounting structure can be applied by co-extrusion with the sash profile, by post-extrusion, manually or automatically and can comprise, for example, at least one of a bead of adhesive, a preformed adhesive foam, a preformed adhesive tape, or a chemical sealant. The adhesive mounting structure can be combined with a desiccant.

A sash frame is used to provide an integrated multipane window unit. A first strip of adhesive material is applied to the sash frame. The outside surface of a first glazing pane is mounted to the first strip of adhesive material. A second strip of adhesive material is applied to the sash frame substantially parallel to the first strip. The outside surface of the second glazing pane is mounted to the second strip of adhesive material. The inside surfaces of the glazing panes face each other. The glazing panes can be mounted to the sash frame by drawing them outwardly against their respective adhesive strips. Respective spacer structure elements can be provided as part of the sash frame to provide structural support and maintain a consistent desired spacing between the glazing panes.

Various desiccant, vapor barrier and/or sealant components are provided for a multipane window unit sash assembly having an integral glazing pane mounting structure. The components have varying shapes and features, which may include glazing pane mounting surfaces, spacer functions, dual seal capabilities and muntin bar retaining functions. Various materials can be used to fabricate the components, including adhesive, sealant, sealant strip, tape, foam, resin, metallic or plastic materials, or combinations of such materials. The components may be preformed, extruded onto the sash, or otherwise applied. Automated assembly of the components to the sash is also disclosed.
摘要:
Methods and apparatus are provided for mounting one or more glazing panes or insulating glass units into a window sash frame member having spaced side walls joined by an inner facing frame surface with a spacing structure disposed on the frame surface. Glazing panes are placed against strips of adhesive sealant within the window sash frame. Folding glazing beads hingedly attached to the side or inner walls of the frame member are folded against the glazing panes to secure them to the window sash frame member and/or to cover the glazing pane edges.
摘要:
A window sash frame is provided with a glazing pane installation opening accessible from a first side thereof and a glazing pane support surface on a second side thereof. A first glazing pane is inserted into the installation opening and an outside surface perimeter of the pane is placed adjacent to the support surface. A second glazing pane is then inserted into the opening. An inside surface perimeter of the second pane is mounted (e.g., via an adhesive bead, strip, tape or foam) to an inside surface perimeter of the first glazing pane. The adhesive thickness is such that the panes are separated by a space, which can contain air or an inert insulating gas. A glazing bead is installed along at least a portion of the glazing pane installation opening after the glazing panes have been inserted. A spacer can alternatively or additionally be provided between the glazing panes.
摘要:
Techniques are provided for mounting simulated muntin bars, preassembled muntin grids and the like between parallel glazing sheets in an integrated multipane window sash. Among the mounting techniques disclosed are clips for holding simulated muntin components to a spacing and mounting structure of an integrated multipane window sash. Clip-less embodiments are also presented, as well as a one-piece sash that includes integral muntins and an integral spacing and mounting structure for the glazing sheets.
