Thin film metal-insulator-metal capacitors having enhanced surface area are formed by a substituting metal for silicon in a preformed electrode geometry. The resulting metal structures are advantageous for high-density DRAM applications since they have good conductivity, enhanced surface area and are compatible with capacitor dielectric materials having high dielectric constant.

The present invention comprises a pair of bead plates on which beads are formed, and an intermediate plate on which first and second stepped portions are formed. One of the bead plates is provided with auxiliary beads so as to prevent a full compression of the beads and increase the sealability. This metal gasket comprises first and second bead plates having beads and extending along the circumferences of holes, and an intermediate plate interposed between the bead plates. The intermediate plate...

In the recovery of an electrically conductive metal from a liquid containing the metal in solution, a cathode member for deposition of the metal by electrolysis, comprises a carrier sheet with a cathode element of the metal to be recovered, on one side of the sheet; the carrier sheet is of a material from which the metal is readily refinable when smelted with the carrier sheet; the cathode member has particular application for removal of the silver content of fixer solution in photography; suita...

A metal gasket excellent in sealing performance and capable of sealing with a small pressing force. The metal gasket comprises at least one metal sheath with a C-shaped cross-section and a ring elastic core surrounded by the metal sheath. The metal gasket provides a seal upon exertion of a force in the axis center direction. The metal sheath has a locally thin cross-section over the whole annular length, and when the metal sheath subject to a force and deformed, the deflection in the axis direct...

This metal gasket comprises a bead base plate with first beads and a sub-plate stacked on the bead base plate. The sub-plate is made of a thick metal plate and formed with second and third beads and stepped portions. The second beads, the third beads and the stepped portions combine to form triple seal lines, which improve the sealing function. The sub-plate is formed with the second beads opposing the first beads of the bead base plate, with the high third beads formed inside the second beads a...

A double-walled metal building is provided wherein the exterior walls snap into place. The exterior walls are formed of panels which have inturned lips at each side which fit into mating slots and the bottom is provided with clips to hold the bottom of the panel in place. The panel is secured by a top cap which covers the tops of both the interior and the exterior walls, locking the structure together. The only fastening elements which must be installed by workmen are self-tapping screws holding...

A metal truss comprises elongated top chord members connected to each other at their ends. A first elongated bottom chord member is connected at its ends to the top chord members adjacent the free ends of the top chord members. A second elongated bottom chord member is connected at its ends to the top chord members, or directly to the first bottom chord member via spacers, such that the second bottom chord member is spaced below the first bottom chord member. At least one web member is positione...

An alloy particularly suited for use as an inert gas shielded-arc filler metal containing 28% to 35% chromium, 13% to 18% iron, 2.8% to 4.2% aluminum, 0.1% to 3.8% manganese, up to 0.2% silicon, 0.3% to 0.8% titanium, 0.04% to 0.15% carbon and the balance essentially nickel. The filler provides the capability for making substantially defect-free welds in heavy section thicknesses that have excellent elevated temperature carburization resistance and strength.

Infusible metal alloys are employed both as a parts material and as a brazing spelter for the connection of various parts and components made of materials based upon infusible metals and compounds, ceramics, graphite and the like. The alloys are based upon hafnium to which is added some elements selected from the subgroup B of the first group of the periodic system and some elements featuring melting point lying above 600.degree. C selected from the third to eighth groups of the periodic system.

A honeycomb structure brazed with an outer casing has a large corrugated foil and a small corrugated foil overlapped and wound alternately and formed like a cylinder by diffused junction. The large corrugated foil and the small corrugated foil has 20 .mu.m in thickness. The honeycomb structure has 900 cells/square inches in cell density. The large corrugated foil has a wave height of 0.81 mm and a pitch of 1.71 mm. The small corrugated foil has a wave height of 0.05 mm to 0.18 mm and a pitch of ...
