A touch panel having a panel body formed by transparent upper and lower electrodes spaced a predetermined distance. The touch panel is mounted on a front surface of a display device to detect a coordinate at a depressed position on the upper electrode. The improvement comprises a transparent insulating liquid material filled between the upper and lower electrodes and a coloring agent containing pigment or dyestuff dispersed in the liquid material. In another aspect, the improvement comprises a t...

A building system includes a plurality of building panels which are connected together to form a wall structure and are then connected to roof panels to form a roof structure. Each of the panels is formed by rotational molding to form a hollow body. The hollow body can be filled with a foamed insulation material. Side edges of the hollow body include either a projection or a correspondingly shaped recess which has a web and a bulbous part of increased width on the outer end of the web so that th...

A display panel includes a group of cathode segments, each segment comprising two cathode bars adapted to glow simultaneously to produce a single segment and circuits for coupling energizing signals to each bar of a segment separately and simultaneously so that if one bar does not light, the other will and proper display will be achieved. The panel also includes anode electrodes.

A stiffened panel of the type formed by a method including subjecting two metal sheets, both capable of superplastic deformation and diffusion bonding, which are positioned face to face, to a bending and deforming process during which the sheets are joined to one another at a series of spaced substantially continuous joint lines across their faces, and during which parts of said sheets between the joint lines are superplastically deformed in a mould to form a series of cavities between the two s...

A panel assembly including at least two panels and one or more connectors is disclosed in which the individual panels are provided with peripheral slots or channels which have contiguous walls which grasp connectors and serve to join two adjacent panels. The connectors are provided with slot penetrating ends and are dimensioned to be gripped within the slots.

A panel fastener having a first section to be buried in one panel and a second section to be buried in another mating panel, said first section including: a hook plate fitted to an eccentric cam rotatably provided in said first section; and a leaf spring forced in between said hook plate and said eccentric cam. The two panels are connected and fastened together by rotating said eccentric cam in order to rotate said hook plate together with said eccentric cam, and by further rotating said cam in ...

An antiglare panel is formed of a series of identical inter-locked strips. Each of the strips is formed of a series of "W" shapes having two connected short legs formed at right angles to each other and two long legs extending at right angles from a respective short leg to define the "W" shape. The long legs of adjacent "W's" are formed at right angles to define a projecting right angle. The projecting right angles of one strip are positioned within the recessed right angles of an adjacent strip...

A floor panel for use in elevated floor assemblies is disclosed which includes a core member, a top sheet and a bottom sheet positioned on opposed sides of the core member and a flexible edge member operatively positioned between the top and bottom sheet. The bottom sheet has an upwardly deflected edge which forms a first shoulder. The top sheet includes a central section, an edge section and a connecting section operatively connecting the central section to the edge section. The edge section is...

A platelike structural panel is disclosed having spaced surfaces with a foamed core material therebetween. The surfaces are formed of sheet metal plates having adjacent longitudinal edges which are bent so as to form grooved seams joining and locking the plates together. The surfaces may be formed by continuously joining and seaming sheet metal from a coil and the foamed core may be formed by foaming the material between the joined plates or by gluing already foamed material between the plates.

A membrane panel including at least one electrical component. The panel includes a rigid support member having substantially planar top and bottom surfaces. At least one void region, or hole, extends from the bottom surface of that support member. A flexible top member including at least one flexible layer, overlies the support member. A flexible bottom member including at least one flexible layer underlies the support member. The bottom member has its upper surface affixed to the bottom surface...
